入力 If you enter a production plan that does not equalize the amount of goods to the dispatch plan tool of the logistics support software mentioned above, the quantity of trucks will change every day because the quantity of goods changes every day. Due to the shortage of trucks and drivers in recent years, few logistics companies can cope with changing the number of trucks every day. In such a situation, in order to secure the number of transportation vehicles necessary for the transportation of the product, it is necessary to prepare the number of trucks adapted for a large amount of transportation. In this case, when the amount of goods to be transported is small, the loading rate of the truck becomes low and waste occurs, so that the distribution cost becomes high.

The present invention has been made in view of the above-described problems, and an object of the present invention is to make it possible to reduce logistics costs while securing the number of transportation vehicles necessary for transportation of transportation objects.

The transportation management device determines whether or not the transportation vehicle uses an automobile road. The base terminal includes a completion time information acquisition unit and a first transmission unit. The completion time information acquisition unit acquires completion time information indicating a time at which preparation of the transportation object is completed. The first transmission unit transmits completion time information to the transportation management device. The in-vehicle device includes a position information acquisition unit and a second transmission unit. The position information acquisition unit acquires position information indicating the position of the transport vehicle on which the position information acquisition unit is mounted. The second transmission unit transmits the position information to the transportation management device.

The receiving unit receives completion time information from the base terminal and receives position information from the in-vehicle device. A 1st memory | storage part memorize | stores the transport object information which shows the specification of a transport object, and the preparation plan information which shows the preparation plan of a transport object. A 2nd memory | storage part memorize | stores the load information which shows the loadable amount of a transport vehicle, and the base information which shows the location of the base including a loading base. The quantity prediction unit calculates the predicted quantity by predicting the quantity of the transportation object prepared at the loading base based on the transportation object information, the preparation plan information, and the completion time information. The arrival / departure time prediction unit is based on the location information, the operation plan information indicating the operation plan between the bases of the transport vehicle, and the base information, the departure time from the base of the transport vehicle that has arrived at the loading base and the next base Predicting arrival time to obtain predicted departure time and predicted arrival time, and based on the obtained predicted departure time and predicted arrival time, estimated arrival times at the respective bases of the operation plan of the transportation vehicle arriving at the loading base And the operation plan information is updated by changing the scheduled departure time from each of the bases. The berth usage status prediction unit predicts the usage status of the berth that performs loading and unloading of each base based on the operation plan information updated by the arrival and departure time prediction unit. The use road determination unit includes the load information, the predicted amount calculated by the amount prediction unit, the operation plan information updated by the arrival / departure time prediction unit, and the berth usage status of each base predicted by the berth usage state prediction unit.

The use road judgment part 17 which judges whether to do is provided.

The communication unit 11 acquires completion time information from the production site terminal 2 and acquires vehicle state information and latitude / longitude information from the in-vehicle device 3. The communication unit 11 stores the acquired completion time information in the production-related storage unit 12 and stores the acquired vehicle state information and latitude / longitude information in the transport-related storage unit 13. The communication unit 11 is an example of a receiving unit in the present invention.

In addition to the completion time information stored by the communication unit 11, the production related storage unit 12 stores production plan information indicating a product production plan at a production site and product information indicating a product specification. Production plan information and product information may be stored in advance, may be configured to be input by a user, or may be configured to be acquired from an external server. The production related storage unit 12 is an example of a first storage unit in the present invention.

The production plan information shown in FIG. 3 includes a “date” indicating the date of manufacturing the product, a “product” indicating the name of the product to be manufactured, a “manufacturing line” indicating the manufacturing line to be used, and the number of products to be manufactured. "Production quantity" indicating "Production number", "Scheduled start time" indicating the scheduled time to start manufacturing, and "Break time" indicating a predetermined day break time. In the production plan information of FIG. 3, for example, for the product Pa manufactured on 2018/03/01, the manufacturing line is L1, the number of manufactured products is 10, the scheduled start time is 9:00, and the break time is 0:45. The item “product” is not limited to the name of the product, but may be information identifying the product. The item “manufactured number” may be the number of lots of products to be manufactured. When the item “manufactured number” is the number of lots of a product to be manufactured, the item “lot number” may not be included in the product information. Further, when there is one production line at the production base, the item “production line” may not be present.

Subsequently, the completion time information stored in the production-related storage unit 12 will be described with reference to FIG. The completion time information shown in FIG. 4 includes a “date” indicating the date of the day, a “product” indicating the name of the manufactured product, and a serial number in the order of manufacture for each lot of the same product manufactured on that day. It has items of “lot No.” which is a number to be assigned and “completion time” indicating the time when the lot is completed. The item “product” is not limited to the name of the product, but may be information identifying the product. The item “Lot No.” is not limited to serial numbers, and may be information identifying a lot. In the completion time information of FIG. Lots 1 to 4 have already been completed. Lots 5-10 are not yet complete.

Returning to FIG. 1, when the completion time information is stored in the production-related storage unit 12, the volume floor area prediction unit 14 predicts the volume and floor area of the product produced on the day at the production base. In the following description, the day is assumed to be 2018/03/01. The volume floor area prediction unit 14 refers to the production plan information on that day and calculates the number of production lots of the product indicated by the completion time information. The volume floor area prediction unit 14 assigns information for identifying the lot to each lot of the product. The volume floor area prediction unit 14 calculates the volume and floor area of one lot of the product based on the product information.

Specifically, the volume floor area prediction unit 14 calculates the scheduled completion time of each lot of the product in the production plan based on the production plan information and the product information. The volume floor area prediction unit 14 calculates a production result difference that is a difference between the latest completion time and the scheduled completion time of the completed lot indicated by the completion time information. The volume floor area prediction unit 14 calculates an adjustment time obtained by adjusting the scheduled completion time of an unfinished lot using the production result difference. The volume floor area prediction unit 14 assumes that the volume and floor area of one completed product increase at the completion time of a completed lot and the adjustment time of an unfinished lot, Predict volume and floor area. Hereinafter, the volume predicted by the volume floor area prediction unit 14 is referred to as a predicted volume, and the predicted floor area is referred to as a predicted floor area.

The volume floor area prediction unit 14 generates predicted volume floor area information indicating the predicted volume and the predicted floor area, and sends the predicted volume floor area information to the use road determination unit 17. Further, the volume floor area prediction unit 14 corrects the scheduled start time of a product manufactured on the same production line as the product indicated by the completion time information in the production plan information, and updates the production plan information. The volume floor area prediction unit 14 is an example of a quantity prediction unit in the present invention. The scheduled completion time of each lot of product may be calculated in advance or may be included in the production plan information.

Here, the predicted volume floor area information generated by the volume floor area prediction unit 14 will be described with reference to FIG. The predicted volume floor area information shown in FIG. 5 includes “date” indicating the date of the day, “product” indicating the name of the product to be manufactured, “lot No.” identifying each lot, and product stacking possible. “Number of stackable numbers” indicating the number, “Scheduled time to start the lot” indicating the scheduled time to start manufacturing the lot, “Break time” indicating the break time during the manufacturing of the lot, and the lot is completed “Scheduled completion time” indicating the scheduled time to perform, “volume” indicating the volume of one lot of product, “floor area” indicating the floor area occupied when one lot of product is placed, and the lot is completed “Adjustment time” indicating the completed time, and “adjustment time” indicating the adjustment time obtained by adjusting the scheduled completion time based on the latest completion time of the completed lot when the lot is incomplete Shows the predicted volume of the finished product lot at It has a "prediction volume", the item of the shows the predicted floor area of the lot of the finished pre-product at the time of the "adjustment time", "predict floor area". When the lot has been completed, the completion time is recorded in the item “adjustment time”. The time in parentheses in the figure is the completion time. The item “product” is not limited to the name of the product, but may be information identifying the product. The item of “Lot No.” has lot No. However, the present invention is not limited to this.

The predicted volume floor area information shown in FIG. 5 indicates the predicted volume and the predicted floor area of the product Pa manufactured on the day at the production site. In generating the predicted volume floor area information illustrated in FIG. 5, the volume floor area prediction unit 14 refers to the product information in which “product” is the product Pa from the product information illustrated in FIG. 2. The volume floor area prediction unit 14 refers to the production plan information in which “date” is 2018/03/01 and “product” is the product Pa from the production plan information shown in FIG. The volume floor area prediction unit 14 refers to the completion time information shown in FIG.

The volume floor area prediction unit 14 calculates the number of production lots of the product Pa by dividing the value of the “production number” of the product Pa in the production plan information by the value of the “lot number” of the product information. Here, 10 ÷ 1 = 10 lots are manufactured. The volume floor area prediction unit 14 assigns serial numbers 1 to 10 to 10 lots of the product Pa to be manufactured on the day, and records them in the item “lot No.”. The volume floor area prediction unit 14 records the “number of stackable numbers” value of the product Pa of the product information in the item “number of stackable numbers”. The volume floor area prediction unit 14 calculates the volume and floor area of one lot of the product Pa based on the value of “1 lot size” of the product Pa in the product information, and calculates the calculated values as “volume” and “floor area”. In the item. The volume is determined by the formula of width (mm) ÷ 1000 × depth (mm) ÷ 1000 × height (mm) ÷ 1000 = volume (m ³ ). The floor area is determined by the formula of width (mm) ÷ 1000 × depth (mm) ÷ 1000 = floor area (m ² ). Here, the volume is 0.960 (m ³ ) and the floor area is 0.800 (m ² ).

The volume floor area prediction unit 14 calculates a scheduled start time, which is a scheduled time to start manufacturing each lot, from the “scheduled start time” of the product Pa in the production plan information. The scheduled start time of each lot is the time when the “scheduled start time” of the product Pa in the production plan information is set as the scheduled start time of the first lot, and the value of the “cycle time” of the product Pa in the product information is added in order. is there. Here, the “planned start time” of the product Pa in the production plan information is 9:00, and the value of the “cycle time” of the product Pa in the product information is 0:00. The scheduled start times of 1 to 10 are times when 0:03 has elapsed in order from 9:00. The volume floor area prediction unit 14 records the calculated scheduled start time of each lot in the item “scheduled start time of lot”.

When there is a pre-designated break time period between the scheduled start time of each lot and the time when the “lead time” value of the product Pa of the product information is added, the volume floor area prediction unit 14 In the item “time”, the value of “break time” of the product Pa in the production plan information is recorded. If there is no pre-designated break time period between the scheduled start time of each lot and the time when the “Lead time” value of the product Pa in the product information is added, the “break time” item is set to 0: 00 is recorded. Here, the break time zone is from 12:00 to 12:45, and the items of “break time” of each lot are all 0:00. The volume floor area prediction unit 14 calculates a time obtained by adding the value of the “lead time” and the “break time” of the product Pa in the product information to the scheduled start time of each lot, and the item “scheduled completion time” To record.

The volume floor area prediction unit 14 includes the lot No. of the product Pa in the completion time information in the item “completion time”. Record the value of “Completion Time” from 1 to 10. Although the value of “completion time” of the completion time information is in units of seconds, the volume floor area prediction unit 14 records the value of “completion time” in units of minutes in accordance with the item “scheduled completion time”. When the item of “completion time” has a value, the volume floor area prediction unit 14 records the value of “completion time” in the item “adjustment time” of the lot. When there is no value in the item “completion time”, the volume floor area prediction unit 14 calculates an adjustment time obtained by adjusting the scheduled completion time based on the latest “completion time” value. In the predicted volume floor area information shown in FIG. There is a value in the “completion time” of lots 1 to 4, and lot No. There is no value for the “completion time” of lots 5 to 10.

Here, a method for calculating the adjustment time when the “completion time” item has no value will be described in detail. First, the volume floor area prediction unit 14 pays attention to the latest lot of the “completion time”, and calculates a production performance difference indicating a delay in progress or an advance. Here, the latest “completion time” is 13:59. When there is a pre-designated break time zone between the “lot start scheduled time” of the lot and the latest “completion time”, the volume floor area prediction unit 14 sets the break time during the production of the lot. As a result, the value of the “break time” of the product Pa in the production plan information is set as the actual break time. If there is no pre-designated break time zone between the “scheduled start time of the lot” and the latest “complete time”, the volume floor area prediction unit 14 does not take a break time during the production of the lot. As a thing, the actual break time is set to 0:00. Here, since there is a break time zone from 9:09 to 13:59, the actual break time is set to 0:45. The volume floor area prediction unit 14 subtracts the value of the actual break time from the difference between the latest value of “completion time” and the value of “scheduled completion time” to calculate the production result difference. When the latest “completion time” is earlier than the “scheduled completion time”, the production performance difference is a negative value. On the other hand, when the latest “completion time” is later than the “scheduled completion time”, the production performance difference is a positive value. Here, since the latest “completion time” is 13:59, the “scheduled completion time” is 11:39, and the actual break time is 0:45, the production performance difference is +1: 35.

The volume floor area prediction unit 14 calculates a time obtained by adding the production result difference to the “scheduled completion time” for each lot having no value in the “completion time” item. If there is a pre-designated break time zone between the “lot start scheduled time” and the “scheduled completion time” plus the production performance difference, the break time will be taken during the production of the lot. The adjustment time is calculated by further adding the value of the “break time” of the product Pa in the production plan information to the time obtained by adding the production result difference to the “scheduled completion time”. If there is no pre-designated break time between the "lot start scheduled time" and the "scheduled completion time" plus the production difference, it is assumed that no break time will be taken during the production of the lot. The time obtained by adding the production result difference to the “scheduled completion time” is set as the adjustment time. For example, the lot number shown in FIG. In the case of the lot of 5, when the production result difference + 1: 35 is added to the “scheduled completion time” 11:42:00, it becomes 13:17. Since there is a break time zone between 9:12 and 13:17, the volume floor area prediction unit 14 adds 14:02 obtained by adding the break time 0:45 to 13:17 as the lot number. The lot adjustment time of 5 is assumed. The volume floor area prediction unit 14 records the calculated adjustment time of each lot in the item “adjustment time”.

The volume floor area prediction unit 14 calculates the predicted volume by adding the value of “volume” every time one lot is manufactured. The volume floor area prediction unit 14 records the calculated predicted volume in the item “predicted volume”. Since the product Pa has a “number of stackable numbers” of 2, the volume floor area prediction unit 14 calculates the predicted floor area by adding the value of “floor area” every time two lots are manufactured. The volume floor area prediction unit 14 records the calculated predicted floor area in the item “predicted floor area”. The “predicted volume” item indicates the predicted volume of the finished product Pa at the time of “adjustment time”, and the “predicted floor area” item indicates the completed product Pa at the time of “adjustment time”. The estimated floor area is shown. In the predicted volume floor area information shown in FIG. 1-No. At the time point 14:17 when all 10 lots were produced, the predicted volume is 9.600 m ³ and the predicted floor area is 4.000 m ² .

The volume floor area prediction unit 14 in advance between the “planned start time” of the product Pb manufactured on the same production line L1 as the product Pa in the production plan information and the time when the production result difference is added to the “scheduled start time”. If there is no designated break time zone, the production performance difference is added to the “scheduled start time” of the product Pb. On the other hand, if there is a pre-designated break time period between the “scheduled start time” of the product Pb and the time when the production result difference is added to the “scheduled start time”, the “scheduled start time” of the product Pb is set. Add the actual production difference and the value of the set break time. The volume floor area prediction unit 14 also performs this process for the product Pc and the product Pd manufactured on the same manufacturing line L1 as the product Pa, and updates the production plan information.

In FIG. 5, in order to facilitate understanding, “product”, “lot No.”, “number of stackable numbers”, “volume”, “floor area”, “lot start” used for calculating the predicted volume and the predicted floor area. An example of predicted volume floor area information including items of “scheduled time”, “break time”, “scheduled completion time”, and “completion time” has been shown, but the predicted volume floor area information includes at least “date”, “adjustment time” ”,“ Predicted volume ”, and“ predicted floor area ”may be included.

In a warehouse that stores products manufactured at a production site, there are a set volume that is the upper limit of the volume of products that can be stored and a set floor area that is the upper limit of the floor area of products that can be stored. The predicted volume and the predicted floor area calculated by the volume floor area prediction unit 14 increase each time a product is manufactured, and may exceed the set volume and the set floor area, respectively.

The state where the predicted volume calculated by the volume floor area prediction unit 14 exceeds the set volume will be described with reference to FIG. FIG. 6 is a graph showing the time transition of the total predicted volume of all products manufactured at the production site on the day. The graph of FIG. 6 is displayed at intervals of 5 minutes for convenience, but the calculation of the predicted volume is performed in units of 1 minute. In the graph of FIG. 6, the set volume of the production base warehouse is 200 m ³ , and the predicted volume increases every time the product is manufactured, and the predicted volume exceeds the set volume at 10:00. Similarly, the total estimated floor area of all products produced at the production site may exceed the set floor area. Actually, since the transportation vehicle arrives at the production base and carries out the product from the warehouse, the volume and floor area of the product in the warehouse are reduced by the amount carried out each time the transportation vehicle arrives. The arrival / departure time prediction unit 15 predicts the arrival time of the transport vehicle at the production site.

FIG. 9 shows an example of the vehicle state information acquired from the in-vehicle device 3 of the truck T1 on that day. In the vehicle state information shown in FIG. 9, for example, in the truck T1, the worker starts work from 8:50:23 and departs to the next base at 9:10:55. The transport-related storage unit 13 stores vehicle state information for all transport vehicles.

Subsequently, latitude and longitude information will be described with reference to FIG. The latitude / longitude information shown in FIG. 10 includes “transport vehicle” indicating the name of the transport vehicle, “date” indicating the date of the day, and “time” indicating the time when the latitude and longitude of the current position of the transport vehicle are measured. , It has items of “latitude” indicating the measured latitude and “longitude” indicating the measured longitude. The item “transport vehicle” is not limited to the name of the transport vehicle, but may be information identifying the transport vehicle. In the example of FIG. 10, the latitude / longitude information acquired from the vehicle-mounted device 3 of the truck T1 on the day is shown. For example, the track T1 is at a position of latitude 34.2545 and longitude 135.2353 at 8:40:00. The transport-related storage unit 13 stores latitude / longitude information of all transport vehicles. The load amount information will be described later.

Returning to FIG. 1, the arrival / departure time prediction unit 15 first determines whether there is a transport vehicle (hereinafter referred to as a target transport vehicle) that has arrived at the production site based on the latitude and longitude information. When determining that there is a target transport vehicle, the departure / arrival time prediction unit 15 determines whether or not vehicle state information indicating “work” of the target transport vehicle is recorded in the transport-related storage unit 13. When it is determined that the vehicle state information indicating the “work” of the target transport vehicle is recorded in the transport-related storage unit 13, the arrival / departure time prediction unit 15 is based on the past vehicle state information, the past latitude / longitude information, and the base information. An average work time is calculated when the same transport vehicle as the target transport vehicle at the same base is in the same state “work”. Hereinafter, the time indicated by the vehicle state information indicating the “work” of the target transport vehicle recorded in the transport related storage unit 13 is referred to as a state start time. The arrival / departure time prediction unit 15 adds the average work time calculated to the state start time to calculate the state end scheduled time. A production site is an example of a loading site.

The departure / arrival time prediction unit 15 predicts a time obtained by calculating the estimated state end time in minutes as a departure time from the production base of the target transport vehicle. Hereinafter, the departure time predicted by the arrival / departure time prediction unit 15 is referred to as a predicted departure time. The arrival / departure time prediction unit 15 calculates the average travel time from the production base to the next base based on the past vehicle state information, the past latitude / longitude information, the operation plan information, and the base information of the target transport vehicle. The arrival / departure time prediction unit 15 predicts a time obtained by adding the average travel time calculated to the scheduled state end time in minutes to the arrival time of the target transport vehicle at the next base. Hereinafter, the arrival time predicted by the arrival / departure time prediction unit 15 is referred to as a predicted arrival time. The past vehicle state information and the past latitude / longitude referred to by the arrival / departure time prediction unit 15 may be limited in duration, for example, for the past 20 days and for the past one year. In addition, when there is no past vehicle state information or past latitude / longitude information, a preset initial value may be used.

Next, the arrival / departure time prediction unit 15 indicates the “estimated arrival time” of the target transport vehicle at the production base in the operation plan corresponding to the operation plan information, in the latitude and longitude information indicating that the target transport vehicle has arrived at the production base. Set the time. The corresponding operation plan is specified with reference to vehicle state information and latitude / longitude information. The arrival / departure time prediction unit 15 sets the estimated departure time from the production base of the target transport vehicle in the corresponding operation plan as the predicted departure time from the production base where the target transport vehicle arrived. The arrival / departure time prediction unit 15 sets the estimated arrival time to the next base of the target transport vehicle in the corresponding operation plan as the calculated predicted arrival time to the next base.

The arrival / departure time prediction unit 15 calculates a difference in transportation performance, which is a difference between the predicted arrival time of the target transport vehicle at the next base and the original “estimated arrival time” at the next base of the target transport vehicle in the corresponding operation plan. calculate. The arrival / departure time predicting unit 15 uses the “estimated arrival time” and “scheduled departure time” of the operation plan after the “scheduled departure time” item of the next base, respectively, based on the “scheduled arrival time” and “scheduled departure time”. The operation plan information is updated to the time obtained by adding the difference in transportation results to the time. The departure / arrival time prediction unit 15 is an example of a departure / arrival time prediction unit in the present invention.

Here, the process executed by the arrival / departure time prediction unit 15 will be described in detail with reference to FIGS. 11 and 12. In the example of FIG. 11, the truck T1 arrives at the factory that is the production base at 8:50:00 on that day. Referring to the operation plan information shown in FIG. 7, the next base of the truck T1 is an external warehouse. Returning to FIG. 11, when the departure / arrival time prediction unit 15 determines that the truck T1 has arrived at the factory, the departure / arrival time prediction unit 15 waits for the vehicle state information indicating the “work” of the truck T1 to be recorded in the transport-related storage unit 13.

When the vehicle state information indicating the “work” of the truck T1 is recorded in the transport-related storage unit 13, the departure / arrival time prediction unit 15 sets the time 8:50:23 indicated by the vehicle state information indicating the “work” of the truck T1. State start time. The arrival / departure time prediction unit 15 calculates the average when the state of the truck T1 is “work” in the factory based on the past vehicle state information, the past latitude / longitude information, and the base information stored in the transport-related storage unit 13. The work time is calculated and added to the state start time to calculate the state end scheduled time 9:10:57. The arrival / departure time prediction unit 15 sets 9:10, which is the estimated state end time in minutes, as the predicted departure time from the factory. The arrival / departure time prediction unit 15 calculates the average travel time from the factory to the external warehouse based on the past vehicle state information, the past latitude / longitude information, and the base information stored in the transport-related storage unit 13, and is scheduled to end the state. Add to the time 9:10:57 to calculate the predicted arrival time 10:00 to the external warehouse in minutes.

FIG. 12 shows an example in which the operation plan information shown in FIG. 7 is updated using the predicted departure time and predicted arrival time of the target transport vehicle calculated by the arrival / departure time prediction unit 15 in the example of FIG. In FIG. 12, the first operation plan for which the truck T1 is the factory is the corresponding operation plan. First, the arrival / departure time prediction unit 15 records the time 8:50 indicated by the latitude / longitude information indicating arrival at the factory in the item “estimated arrival time” of the corresponding operation plan in the operation plan information. In the example of FIG. 12, the actual arrival time is displayed in parentheses. The arrival / departure time prediction unit 15 records the calculated predicted departure time 9:10 in the item “scheduled departure time” of the corresponding operation plan, and in the “scheduled arrival time” column of the external warehouse as the next base, The calculated predicted arrival time 10:00 is recorded.

The arrival / departure time prediction unit 15 calculates a transport result difference—10 minutes, which is the difference between the predicted arrival time 10:00 of the external warehouse as the next base and the original time 10:10 of the “estimated arrival time”. In the “Scheduled Arrival Time” and “Scheduled Departure Time” items of the operation plan after the “Scheduled Departure Time” item of the next warehouse, the “Scheduled Arrival Time” and “Scheduled Departure Time” respectively. Record the time of transportation result difference minus 10 minutes and update the operation plan information. When the arrival / departure time prediction unit 15 updates the operation plan information, the berth use state prediction unit 16 predicts the berth use state of each base.

Returning to FIG. 1, the berth usage status prediction unit 16 refers to the operation plan information updated by the arrival / departure time prediction unit 15 and calculates the number of transport vehicles arriving at each base and the time zone in which the berth is used. The berth use state prediction unit 16 determines whether or not berth batting occurs in which the number of arriving transport vehicles exceeds the number of berths. When berth batting does not occur, the berth usage status prediction unit 16 generates berth usage status information indicating the number of transport vehicles arriving at each base and the time zone in which the berth is used.

When berth batting occurs, the berth use state prediction unit 16 sets the estimated arrival time of the transport vehicle waiting by berth batting in the operation plan information updated by the departure / arrival time prediction unit 15 as the scheduled departure time of the first transport vehicle. The process of changing and changing the scheduled departure time of the waiting transport vehicle in accordance with the estimated arrival time is repeated until all berth batting is resolved. When all the berth batting is eliminated, the berth use state prediction unit 16 generates berth use state information indicating the number of transport vehicles arriving at the base and the time zone in which the berth is used. The berth usage status prediction unit 16 sends the generated berth usage status information to the usage road determination unit 17. The berth usage status prediction unit 16 is an example of a berth usage status prediction unit in the present invention.

Here, with reference to FIG. 13A and FIG. 13B, a process in which the berth use state prediction unit 16 predicts the berth use state of each base will be described in detail. 13A and 13B show examples of berth usage status information for the day generated by the berth usage status prediction unit 16. FIG. 13A is an example of berth usage status information in which berth batting has occurred. FIG. 13B is an example of berth use status information in which berth batting is eliminated. In the example of FIG. 13A and FIG. 13B, the display is performed at intervals of 5 minutes for convenience, but the berth usage status is calculated in units of 1 minute.

First, the berth use state prediction unit 16 records the values of the “base” and “berth number” items of the base information (see FIG. 8) in the “base” and “berth number” items of the berth use state information, respectively. To do. Next, the berth use state prediction unit 16 refers to the operation plan information updated by the arrival / departure time prediction unit 15 (see FIG. 12), and the time zone in which the transport vehicle arriving at each base uses the berth, that is, the transport vehicle. “1” is added to the item of the time zone from the scheduled arrival time to the base of the vehicle to the scheduled departure time from the base. As shown in FIG. 13A, berth batting occurs in which three transport vehicles exceeding the number of berths “2” in the factory arrive for 10 minutes 20 minutes to 15 minutes 35 minutes.

When the berth batting occurs, the berth use state prediction unit 16 changes the scheduled arrival time of the transport vehicle waiting by the berth batting in the operation information to the scheduled departure time of the first transport vehicle, and the scheduled departure time of the transport vehicle waiting. Is updated in accordance with the estimated arrival time until all berth batting is resolved, that is, until there is no transport vehicle waiting, and the operation information is updated. The berth usage status prediction unit 16 generates berth usage status information in which the berth batting shown in FIG.

The berth use state prediction unit 16 generates berth use state information that highlights a time zone in which berth batting occurs, as shown in FIG. 13A, and transmits the berth use state information to the in-vehicle device 3 of the transport vehicle via the communication unit 11. Also good. At this time, the berth use status information highlighting the time zone in which berth batting occurs may be transmitted to each transport vehicle or may be transmitted to the transport vehicle on standby. The highlighting method is not limited to the method of inverting the color of the cell in the time zone in which barbating occurs, as in the example of FIG. 13A, but may be bold, or the character color or background color may be changed. .

Returning to FIG. 1, when the usage road determination unit 17 receives the berth usage status information from the berth usage status prediction unit 16, the usage road determination unit 17 first refers to the operation plan information and the base information, and starts from the production base where the target transport vehicle arrives. It is determined whether there is a dedicated road for automobiles on the route to the base. If there is no dedicated road for automobiles, the use road determination unit 17 ends the process. In the case where there is a dedicated road for automobiles, the use road determination unit 17 stores the warehouse of the production base that becomes the maximum amount within the range of the loadable capacity of the transportation vehicle that arrives at the production base based on the load capacity information and the operation plan information. The volume and floor area of the product combination (hereinafter referred to as the unloading volume and unloading floor area, respectively) are calculated. The use road determination unit 17 carries out the unloading volume and the unloading floor area from the predicted volume at the time when the transport vehicle arrives at the production base and the predicted floor area value of the predicted volume floor area information received from the volume floor area prediction unit 14, respectively. The value of is subtracted. The use road determination unit 17 performs this process for all transport vehicles that arrive at the production site on the same day, and updates the predicted volume floor area information.

Here, the load amount information stored in the transport-related storage unit 13 will be described with reference to FIG. The loading amount information shown in FIG. 14 includes “transportation vehicle” indicating the name of the transport vehicle, and “loading platform size” indicating “width”, “depth”, and “height” indicating the size of the transport platform of the transport vehicle. Have items. For example, the size of the loading platform of the truck T1 is 2000 mm wide, 6000 mm deep, and 2800 mm high. The height here indicates the maximum height from the floor surface to the roof when the loading platform has a roof, and the maximum height from the loadable floor surface when the loading platform has no roof. The item “transport vehicle” is not limited to the name of the transport vehicle, but may be information identifying the transport vehicle. Further, the load amount information is not limited to information indicating the size of the loading platform, but may be information indicating the loadable amount of the transport vehicle.

Next, a process in which the use road determination unit 17 subtracts the unloading volume from the predicted volume at the time when the transport vehicle arrives at the production base in the predicted volume floor area information will be described with reference to FIG. FIG. 15 is a graph showing a three-hour time transition from 9 o'clock to 12 o'clock of the total predicted volume of all products manufactured at the production site on that day. The graph of FIG. 15 is displayed at intervals of 5 minutes for convenience, but the process of subtracting the unloading volume from the predicted volume is performed in units of 1 minute. In the example of FIG. 15, the set volume of the production base warehouse is 200 m ³ . The use road determination unit 17 subtracts the unloading volume from the predicted volume between the scheduled arrival time and the scheduled departure time of the transport vehicle. As a result, the predicted volume from 9:00 to 12:00 does not exceed the set volume. Similarly, for the predicted floor area, the use road determination unit 17 subtracts the carry-out floor area from the predicted floor area at the time when the transport vehicle arrives at the production base in the predicted volume floor area information.

Returning to FIG. 1, when the use road determination unit 17 performs the process of subtracting the unloading volume and the unloading floor area from the predicted volume and the predicted floor area, respectively, and updating the predicted volume floor area information, the updated predicted volume floor area information is updated. Based on the above, it is determined whether or not there is a timing at which the predicted volume after the time when the target transport vehicle arrives exceeds the set volume or a timing at which the predicted floor area exceeds the set floor area. When there is no timing exceeding the set volume or the set floor area, the use road determination unit 17 determines that the target transport vehicle does not use the automobile road for movement to the next base. At this time, the use road determination unit 17 may determine that the automobile-only road should not be used. When there is a timing exceeding the determination set volume or the set floor area, the use road determination unit 17 predicts arrival at the next base in the travel time when the target transport vehicle uses the automobile road for moving to the next base. Recalculate the time. The use road determination unit 17 may hold in advance the travel time when the automobile-only road is used, or may calculate from past vehicle state information and past latitude / longitude information.

The usage road determination unit 17 refers to the berth usage status information received from the berth usage status prediction unit 16 and determines whether or not the berth is free when the next arrival point is reached at the predicted arrival time when the automobile-only road is used. Determine whether. When the berth is not vacant, the use road determination unit 17 determines that the target transport vehicle does not use the automobile road for moving to the next base. When the berth is vacant, the use road determination unit 17 determines that the target transport vehicle uses the automobile road for movement to the next base. At this time, the use road determination unit 17 may determine that an automobile-only road should be used. The use road determination unit 17 generates determination result information indicating a determination result of whether or not to use an automobile-only road, and sends the determination result information to the communication unit 11. The communication unit 11 transmits the determination result information received from the use road determination unit 17 to the in-vehicle device 3 of the target transport vehicle. The use road determination unit 17 may transmit the determination result information to the in-vehicle device 3 of the target transport vehicle only in the case of determination using an automobile exclusive road. The usage road determination unit 17 is an example of a usage road determination unit in the present invention.

When the communication unit 33 of the in-vehicle device 3 receives the determination result information from the transportation management device 1, the communication unit 33 displays the information on the display unit 34. Here, an example of the determination result information displayed on the display unit 34 is shown in FIG. In the determination result information in FIG. 16, it is instructed to use the expressway that is an automobile-only road for the movement to the external warehouse that is the next base for the truck T1 that is the target transport vehicle.

Each process of 17 is performed.

The temporary storage unit 101 is, for example, a RAM (Random-Access Memory). The temporary storage unit 101 loads a control program stored in the storage unit 102 and is used as a work area for the calculation unit 103.

The storage unit 102 is a nonvolatile memory such as a flash memory, a hard disk, a DVD-RAM (Digital Versatile Disc-Random Access Memory), and a DVD-RW (Digital Versatile Disc-Rewritable). The storage unit 102 stores in advance a program for causing the calculation unit 103 to perform processing of the transportation management apparatus 1, and supplies data stored in the program to the calculation unit 103 in accordance with an instruction from the calculation unit 103. Data supplied from the unit 103 is stored. The production-related storage unit 12 and the transport-related storage unit 13 are configured in the storage unit 102.

The input unit 104 is an interface device that connects an input device such as a keyboard and a pointing device and an input device such as a keyboard and a pointing device to the BUS. For example, in the case of a configuration in which the user inputs production plan information, product information, operation plan information, site information, or load capacity information, when the user inputs information to the transportation management device 1, the information is input via the input unit 104. Information is supplied to the calculation unit 103.

The external output unit 105 is a network termination device or wireless communication device connected to the network, and a serial interface or LAN (Local Area Network) interface connected to them. The external output unit 105 functions as the communication unit 11.

The display unit 106 is a display device such as a CRT (Cathode Ray Tube) or an LCD (Liquid Crystal Display). For example, in the case of a configuration in which the user inputs production plan information, product information, operation plan information, base information, or load capacity information, the display unit 106 displays an operation screen.

The communication unit 11, the production related storage unit 12, the transport related storage unit 13, the volume floor area prediction unit 14, the arrival / departure time prediction unit 15, the berth usage status prediction unit 16, and the usage road determination unit 17 of the transportation management apparatus 1 shown in FIG.

For example, a computer program for executing the above-described operation is a computer-readable recording medium such as a flexible disk, a CD-ROM (Compact Disc-Read-Only Memory), and a DVD-ROM (Digital Versatile Disc-read-Only Memory). The transportation management apparatus 1 that performs the above-described processing may be configured by storing and distributing the program and installing the computer program in the computer. Further, the transport management apparatus 1 may be configured by storing the computer program in a storage device included in a server device on a communication network such as the Internet and downloading the computer program by a normal computer system.

Further, when the functions of the transportation management device 1 are realized by sharing of an OS (Operating System) and an application program, or by cooperation between the OS and the application program, only the application program portion is stored in a recording medium or a storage device. May be.

It is also possible to superimpose a computer program on a carrier wave and provide it via a communication network. For example, the above-mentioned computer program may be posted on a bulletin board (BBS, “Bulletin” Board System) on the communication network, and the above-mentioned computer program may be provided via the communication network. The computer program may be started and executed in the same manner as other application programs under the control of the OS, so that the above-described processing may be executed.

Subsequently, the flow of each process executed by the transport management device 1 will be described. First, the volume floor area prediction process executed by the transportation management apparatus 1 will be described with reference to FIGS. 2 to 5 and FIG. The volume floor area prediction process shown in FIG. 18 starts when the power of the transportation management apparatus 1 is turned on. If the communication unit 11 of the transportation management device 1 does not acquire completion time information from the production site terminal 2 (step S11; NO), the communication unit 11 repeats step S11 and waits for acquisition of completion time information. When the communication unit 11 acquires completion time information from the production site terminal 2 (step S11; YES), the communication unit 11 stores the acquired completion time information in the production-related storage unit 12.

When the completion time information is stored in the production-related storage unit 12, the volume floor area prediction unit 14 refers to the production plan information on the day and calculates the number of production lots indicated by the completion time information (step S12). The volume floor area prediction unit 14 assigns information for identifying the lot to each lot (step S13). The volume floor area prediction unit 14 calculates the volume and floor area of one lot of the product indicated by the completion time information based on the product information (step S14).

When the communication unit 11 acquires the completion time information shown in FIG. 4 in step S11, the volume floor area prediction unit 14 sets the value of “Production quantity” of the product Pa in the production plan information shown in FIG. 3 in step S12. The number of production lots of the product Pa is calculated by dividing by the value of “lot number” of the product information shown in FIG. Here, 10 ÷ 1 = 10 lots are manufactured. In step S13, the volume floor area predicting unit 14 assigns serial numbers 1 to 10 to 10 lots of the product Pa manufactured on the day as shown in FIG. In step S14, the volume floor area prediction unit 14 calculates the volume and floor area of one lot of the product Pa based on the value of “1 lot size” of the product Pa in the product information shown in FIG. Here, the volume of one lot of product Pa is 0.960 (m ³ ) and the floor area is 0.800 (m ² ).

18, the volume floor area prediction unit 14 calculates the scheduled completion time of each lot of the product indicated by the completion time information of the production plan on the day based on the production plan information and product information (step S15).

When the volume floor area prediction unit 14 calculates the volume and floor area of one lot of product Pa in step S14, the volume floor area prediction unit 14 calculates the product Pa of the production plan information shown in FIG. 3 in step S15. The “scheduled start time” is set as the scheduled start time of the first lot, and the time when the “cycle time” value of the product Pa in the product information shown in FIG. 2 is sequentially added is calculated as the scheduled start time of each lot. Here, since the “planned start time” of the product Pa in the production plan information is 9:00 and the “cycle time” value of the product Pa in the product information is 0:00, lot No. As shown in FIG. 5, the scheduled start times 1 to 10 are times when 3: 00: 3: 00 have elapsed in order from 9:00:00.

The volume floor area predicting unit 14 has a break time zone 12:00 designated in advance between the scheduled start time of each lot and the time when the “lead time” value of the product Pa of the product information shown in FIG. 2 is added. Determine if there is ~ 12: 45. Since there is no break time zone from 12:00 to 12:45 between the scheduled start time of each lot and the time when “lead time” of 2:30:00 is added, the volume floor area prediction unit 14 All break times during production of 1-10 lots shall be 0:00. The volume floor area predicting unit 14 determines whether the NO. A time obtained by adding the value of “lead time” of the product Pa of the product information to the scheduled start time of the lots 1 to 10 is calculated as the scheduled completion time of each lot.

Returning to FIG. 18, the volume floor area prediction unit 14 adjusts the scheduled completion time of the unfinished lot based on the production result difference that is the difference between the latest scheduled completion time and the completion time of the completed lot. Time is calculated (step S16).

In step S15, the volume floor area prediction unit 14 determines that the NO. When the scheduled completion times of the lots 1 to 10 are calculated, in step S16, the volume floor area prediction unit 14 first focuses on the lot of the latest completion time of the product Pa, and indicates production delay or advance Calculate the difference in performance. As shown in FIG. 5, the latest completion time of the lot of product Pa is the lot number. It is 13:59 of 4 lots. The volume floor area predicting unit 14 determines the lot number. Since there is a pre-designated break time zone from 12:00 to 12:45 from the scheduled lot start time of 9:09 to the completion time of 13:59, the actual break time is set to 0:45. The volume floor area prediction unit 14 subtracts the value of the actual break time from the difference between the latest value of “completion time” and the value of “scheduled completion time” to calculate the production result difference. In the example of FIG. 5, since the latest “completion time” is 13:59, “scheduled completion time” is 11:39, and the actual break time is 0:45, the production performance difference is +1: 35.

The volume floor area prediction unit 14 calculates a time obtained by adding the production result difference to the “scheduled completion time” for each lot having no value in the “completion time” item. The capacity floor area prediction unit 14 determines whether or not there is a pre-designated break time period between the “scheduled launch time” and the time when the production result difference is added to the “scheduled completion time”. When there is a break time zone, the capacity floor area prediction unit 14 assumes that a break time is taken during the production of the lot, and the production plan information shown in FIG. The adjustment time is calculated by further adding the value of the “break time” of the product Pa. When there is no break time zone, the volume floor area prediction unit 14 assumes that no break time is taken during the production of the lot, and sets the time obtained by adding the production result difference to the “scheduled completion time” as the adjustment time. For example, the lot No. of product Pa shown in FIG. In the case of the lot of 5, when the production result difference + 1: 35 is added to the “scheduled completion time” 11:42:00, it becomes 13:17. Since there is a break time zone between 9:12 and 13:17, the volume floor area prediction unit 14 sets 14:02 obtained by adding the actual break time 0:45 to 13:17 as the lot number. The lot adjustment time of 5 is assumed.

Returning to FIG. 18, the volume floor area prediction unit 14 assumes that the volume and floor area of one completed product will increase at the completion time of a completed lot and the adjustment time of an unfinished lot. The floor area is calculated (step S17).

When the volume floor area prediction unit 14 calculates the adjustment time obtained by adjusting the scheduled completion time of the unfinished lot of the product Pa in step S16, one volume of the volume floor area prediction unit 14 is manufactured in step S17. The predicted volume is calculated by adding the value of “volume” every time. Since the product Pa has a “number of stackable numbers” of 2, the volume floor area prediction unit 14 calculates the predicted floor area by adding the value of “floor area” every time two lots are manufactured. That is, the predicted volume shown in FIG. 5 indicates the predicted volume of the finished product Pa at the time of adjustment, and the predicted floor area indicates the predicted floor area of the completed product Pa at the time of adjustment. Yes. In the example of FIG. 1-No. At the time point 14:17 when all 10 lots were produced, the predicted volume is 9.600 m ³ and the predicted floor area is 4.000 m ² .

Returning to FIG. 18, the volume floor area prediction unit 14 corrects the scheduled start time of the product manufactured on the same manufacturing line as the product indicated by the completion time information in the production plan information based on the production result difference, and produces the production plan information. Is updated (step S18). The volume floor area prediction unit 14 generates predicted volume floor area information indicating the calculated predicted volume and the predicted floor area (step S19), and sends it to the use road determination unit 17.

When the volume floor area prediction unit 14 calculates the predicted volume and the predicted floor area of the product Pa in step S17, the volume floor area prediction unit 14 performs the following processing in step S18. The volume floor area prediction unit 14 in advance between the “planned start time” of the product Pb manufactured on the same production line L1 as the product Pa in the production plan information and the time when the production result difference is added to the “scheduled start time”. If there is no designated break time zone, the production result difference is added to the “scheduled start time” of the product Pb. On the other hand, if there is a pre-designated break time period between the “scheduled start time” of the product Pb and the time when the production result difference is added to the “scheduled start time”, the “scheduled start time” of the product Pb is set. Add the actual production difference and the value of the set break time. The volume floor area prediction unit 14 also performs this process for the product Pc and the product Pd manufactured on the same manufacturing line L1 as the product Pa, and updates the production plan information. In step S 19, the volumetric floor area prediction unit 14 generates predicted volumetric floor area information shown in FIG. 5 and sends it to the use road determination unit 17.

Returning to FIG. 18, when the power of the transportation management apparatus 1 is not turned off (step S20; NO), the process returns to step S11 and repeats steps S11 to S20. When the power of the transportation management device 1 is turned off (step S20; YES), the process is terminated.

Subsequently, the arrival / departure time prediction processing executed by the transportation management apparatus 1 will be described with reference to FIGS. 9 to 12 and FIG. The departure / arrival time prediction process shown in FIG. 19 starts when the transportation management apparatus 1 is turned on. The arrival / departure time prediction unit 15 of the transport management device 1 determines whether there is a target transport vehicle that has arrived at the production site each time latitude / longitude information is stored in the transport-related storage unit 13 (step S21). When determining that there is no target transport vehicle (step S21; NO), the departure / arrival time prediction unit 15 repeats step S21 and waits for the arrival of the transport vehicle.

When the departure / arrival time prediction unit 15 determines that there is a target transport vehicle (step S21; YES), it determines whether vehicle state information indicating “work” of the target transport vehicle is recorded in the transport-related storage unit 13 ( Step S22). If it is determined that the vehicle state information indicating the “work” of the target transport vehicle is not recorded in the transport related storage unit 13 (step S22; NO), the arrival / departure time prediction unit 15 repeats step S22 to “ It waits for the vehicle state information indicating “work” to be recorded in the transport-related storage unit 13.

In step S21, when the departure / arrival time prediction unit 15 refers to the latitude / longitude information shown in FIG. 10 and determines that the truck T1 arriving at the production base at 8:50:00 is the target transport vehicle as shown in FIG. In S 22, the departure / arrival time prediction unit 15 waits for the vehicle state information indicating “work” of the truck T 1 to be recorded in the transport-related storage unit 13.

Returning to FIG. 19, when it is determined that the vehicle state information indicating the “work” of the target transport vehicle is recorded in the transport-related storage unit 13 (step S22; YES), the arrival / departure time prediction unit 15 determines the vehicle state information, latitude / longitude information. Then, based on the base information, the estimated end time of the “work” state is calculated as the predicted departure time from the production base where it arrived (step S23). The arrival / departure time prediction unit 15 calculates a predicted arrival time of the target transport vehicle at the next base based on the vehicle state information, the latitude / longitude information, and the base information (step S24). The arrival / departure time prediction unit 15 sets the “scheduled arrival time” to the production base of the target transport vehicle in the corresponding operation plan as the time of the latitude / longitude information indicating that the target transport vehicle has arrived at the production base. The departure / arrival time prediction unit 15 sets the “departure scheduled time” from the production base of the target transport vehicle in the corresponding operation plan to the predicted departure time from the production base at which the target transport vehicle arrives calculated in step S23. The arrival / departure time prediction unit 15 sets the “estimated arrival time” to the next base of the target transport vehicle in the corresponding operation plan as the predicted arrival time at the next base calculated in step S24.

If the departure / arrival time prediction unit 15 determines in step S22 that the vehicle state information indicating the “work” of the first truck T1 shown in FIG. 9 is recorded in the transport-related storage unit 13, the arrival / departure time prediction is performed in step S23. As illustrated in FIG. 11, the unit 15 sets time 8:50:23 indicated by the vehicle state information indicating “work” of the truck T1 as the state start time. The arrival / departure time prediction unit 15 is based on past vehicle state information, past latitude / longitude information, and base information stored in the transport-related storage unit 13, and the state of the truck T1 in the factory is “work”. The average work time is calculated and added to the state start time to calculate the state end scheduled time 9:10:57. The arrival / departure time prediction unit 15 sets the estimated departure time from the factory at 9:10 with the estimated state end time in minutes.

In step S24, the departure / arrival time prediction unit 15 moves from the factory to the external warehouse based on the past vehicle state information, the past latitude / longitude information, and the base information stored in the transport-related storage unit 13, as shown in FIG. The average travel time is calculated. The arrival / departure time prediction unit 15 calculates an estimated arrival time 10:00 to the next external warehouse, which is the unit of minutes by adding the average travel time to the estimated departure time 9:10:57.

As shown in FIG. 12, the arrival / departure time prediction unit 15 records the time 8:50 indicated by the latitude / longitude information indicating arrival at the factory in the “estimated arrival time” item of the corresponding operation plan in the operation plan information. To do. In the example of FIG. 12, the actual arrival time is displayed in parentheses. The arrival / departure time prediction unit 15 records the calculated predicted departure time 9:10 in the item “scheduled departure time” of the corresponding operation plan, and in the “scheduled arrival time” column of the external warehouse as the next base, The calculated predicted arrival time 10:00 is recorded.

Returning to FIG. 19, the arrival / departure time prediction unit 15 sets “estimated arrival time” and “estimated departure time” after the “estimated departure time” item of the next base of the operation plan of the target transport vehicle to “estimated arrival time”, respectively. The schedule information is updated to the time obtained by adding the difference in transportation results to the original time of “and scheduled departure time” (step S25), and the process ends.

In step S24, when the arrival / departure time prediction unit 15 calculates the predicted arrival time 10:00 to the external warehouse that is the next base of the target transport vehicle, in step S25, the departure / arrival time prediction unit 15 A transport result difference—10 minutes, which is the difference between the predicted arrival time 10:00 of the warehouse and the original time 10:10 of the “scheduled arrival time”, is calculated. As shown in FIG. 12, the arrival / departure time prediction unit 15 includes the “estimated arrival time” of the operation plan after the “departure scheduled time” item of the external warehouse which is the next base of the original operation plan information shown in FIG. In the “scheduled departure time” item, the times of “scheduled arrival time” and “scheduled departure time” plus the difference in transportation performance minus 10 minutes are recorded, and the operation plan information is updated.

When the arrival / departure time prediction process is completed, the transportation management device 1 performs a berth use state prediction process for predicting a berth use state at each base. From here, the berth use condition prediction process which the transportation management apparatus 1 performs is demonstrated using FIG. 12, FIG. 13A, FIG. 13B, and FIG. The berth use state prediction process shown in FIG. 20 starts when the arrival / departure time prediction process ends. When the arrival / departure time prediction unit 15 updates the operation plan information, the berth use state prediction unit 16 of the transport management device 1 refers to the operation plan information on the day and uses the number of transport vehicles arriving at each base and the berth time. A band is calculated (step S31). Next, the berth use state prediction unit 16 determines whether or not berth batting occurs (step S32). When berth batting does not occur (step S32; NO), the berth use state prediction unit 16 generates berth use state information indicating the number of transport vehicles arriving at the base and the time zone in which the berth is used (step S34). .

In step S31, the berth use state prediction unit 16 refers to the operation plan information shown in FIG. 12, calculates the number of transport vehicles arriving at each base and the time zone in which the berth is used. When the berth usage status information shown in FIG. 13A in which “1” is added to the item of the time zone from the arrival time to the departure time from the base is generated in step S32, the berth usage status prediction unit 16 in FIG. Regarding usage status information, it is determined that berth batting occurs in which three transport vehicles exceeding the number of berths “2” of the factory arrive for 15 minutes from 10:20 to 35/35.

Returning to FIG. 20, when berth batting occurs (step S 32; YES), the berth use state prediction unit 16 changes the scheduled arrival time of the transport vehicle waiting by berth batting to the scheduled departure time of the first transport vehicle. Then, the scheduled departure time of the waiting transportation vehicle is changed in accordance with the estimated arrival time, and the operation plan information is updated (step S33). The berth use state prediction unit 16 repeats steps S32 and S33 until all berth batting is eliminated. When all the berth batting is eliminated (step S32; NO), the berth use state prediction unit 16 generates berth use state information indicating the number of transport vehicles arriving at the base and the time zone in which the berth is used (step S34). ). The berth usage status prediction unit 16 sends the generated berth usage status information to the usage road determination unit 17 and ends the process.

If the berth usage status prediction unit 16 determines in step S32 that berth batting has occurred with respect to the berth usage status information shown in FIG. 13A, in step S33, the berth usage status prediction unit 16 waits for transportation by berth batting. The scheduled arrival time of the vehicle is changed to the scheduled departure time of the first transport vehicle, the scheduled departure time of the transport vehicle waiting is changed according to the scheduled arrival time, and the operation information updated by the departure / arrival time prediction unit 15 is updated. . The operation information is updated by repeating the process of changing the scheduled departure time of the waiting transport vehicle in accordance with the estimated arrival time until all berth batting is resolved. In step S 34, the berth usage status prediction unit 16 generates berth usage status information in which the berth batting shown in FIG. 13B has been eliminated, and sends it to the usage road determination unit 17.

When the berth use state prediction process is completed, the transportation management device 1 determines whether or not the target transport vehicle uses an automobile road for movement to the next base and displays the determination result on the target transport vehicle. Judgment processing is performed. From here, the use road determination process which the transportation management apparatus 1 performs is demonstrated using FIG.8, FIG.11, FIG.14, FIG.16 and FIG. The usage road determination process shown in FIG. 21 starts when the berth usage status prediction process ends.

When the usage road determination unit 17 of the transportation management apparatus 1 receives the berth usage status information from the berth usage status prediction unit 16, it refers to the operation plan information and the base information, and from the production base where the target transport vehicle arrives to the next base. It is determined whether or not there is a dedicated road for automobiles (step S41). The use road judgment part 17 complete | finishes a process, when there is no vehicle exclusive runway in the path | route from the production base where the object transport vehicle arrived to the next base (step S41; NO). The use road determination unit 17 predicts based on the load amount information and the operation plan information when there is a dedicated road for a car on the route from the production base where the target transport vehicle arrives to the next base (step S41; YES). The value of the unloading volume and the unloading floor area is subtracted from the predicted volume and the predicted floor area value at the time when the transport vehicle of the volume floor area information arrives (step S42). The use road determination unit 17 performs the process of step S42 for all transport vehicles arriving at the production site on the day, and updates the predicted volume floor area information (step S43).

In step S41, based on the operation plan information updated by the berth use state prediction unit 16 and the base information shown in FIG. 8, the usage road determination unit 17 sets the route from the factory to the external warehouse for the truck T1 shown in FIG. If it is determined that there is an expressway Y, in step S42, the use road determination unit 17 calculates the predicted volume floor area information based on the load information shown in FIG. 14 and the operation plan information updated by the berth use state prediction unit 16. The unloading volume value is subtracted from the predicted volume value at the time when the transport vehicle arrives. Similarly, for the predicted floor area, the use road determination unit 17 subtracts the carry-out floor area from the predicted floor area at the time when the transport vehicle having the predicted volume floor area information arrives at the production base. In step S43, the use road determination unit 17 determines the unloading volume and unloading from the predicted volume and predicted floor area value at the time when the transport vehicle arrives in the predicted volume floor area information for all the transport vehicles arriving at the production site on that day. A process of subtracting the value of the floor area is performed, and the predicted volume floor area information is updated.

Returning to FIG. 21, the use road determination unit 17 determines the predicted volume or the predicted floor area after the arrival time of the target transport vehicle exceeds the set volume or the set floor area, respectively, based on the updated predicted volume floor area information. It is determined whether or not there is (step S44). When there is no timing exceeding the set volume or the set floor area (step S44; NO), the use road determination unit 17 determines that the target transport vehicle does not use the automobile exclusive road for moving to the next base (step S45). . When there is a timing exceeding the set volume or the set floor area (step S44; YES), the use road determination unit 17 sets the next travel time when the target transport vehicle uses an automobile-only road to move to the next base. The predicted arrival time at the base is recalculated (step S46).

In step S44, based on the updated predicted volume floor area information, the use road determination unit 17 is a timing at which the predicted volume or the predicted floor area after the time when the truck T1 arrives at the factory exceeds the set volume or the set floor area, respectively. If it is determined that there is, the use road determination unit 17 recalculates the predicted arrival time at the external warehouse based on the travel time when the truck T1 uses the highway Y to travel to the external warehouse.

Returning to FIG. 21, the use road determination unit 17 refers to the berth use state information received from the berth use state prediction unit 16, and confirms whether the next base berth is vacant at the predicted arrival time when the car-only road is used. It is determined whether or not (step S47). When the berth at the next base is not empty (step S47; NO), the use road determination unit 17 determines that the target transport vehicle does not use the automobile road for movement to the next base (step S45). When the berth at the next base is vacant (step S47; YES), the use road determination unit 17 determines that the target transport vehicle uses the automobile-only road to move to the next base (step S48).

In step S47, with reference to the berth use status information shown in FIG. 13B, if the use road determination unit 17 determines that the berth of the external warehouse is vacant at the recalculated predicted arrival time, the use road is determined in step S48. The determination unit 17 determines that the truck T1 uses the highway for movement to the external warehouse.

Returning to FIG. 21, the use road determination unit 17 generates determination result information indicating a determination result as to whether or not to use an automobile-only road (step S49), and sends the determination result information to the communication unit 11. The communication part 11 transmits the determination result information received from the use road determination part 17 to the vehicle-mounted apparatus 3 (step S50), and complete | finishes a process. After step S45, the processing may be terminated, and the use road determination unit 17 may transmit the determination result information to the in-vehicle device 3 only when it is determined to use the automobile-only road.

In step S49, the use road determination unit 17 generates determination result information indicating that the truck T1 uses the highway to move to the external warehouse. In step S50, the communication unit 11 transmits the determination result information to the target transport. When transmitted to the in-vehicle device 3 of the vehicle, a screen shown in FIG. 16 is displayed on the display unit 34 of the in-vehicle device 3.

According to the transportation management system 100 according to the present embodiment, in the manufacturing industry, based on the information obtained from the production base terminal 2 and the in-vehicle device 3 by the transportation management device 1, the amount of products manufactured on the day is predicted, When the quantity of products manufactured on the day exceeds the set upper limit, the number of transportation is increased by displaying an instruction to use an automobile road on the in-vehicle device 3 of the target transportation vehicle, and the quantity of transportation is small By not using an automobile road, logistics costs can be reduced while securing the number of transport vehicles necessary for product transportation.

In the above embodiment, the case where the transport object is an industrial product has been described. However, the transport object in the present invention may be an article transported from a base to another base. For example, the transport object may be a packaged agricultural product, marine product, raw material, material, craft, collection, etc. that can specify the package form, and may be an individual, a liquid, a gas, or a mixture thereof. Furthermore, the packing form does not necessarily need to be identifiable.

Therefore, the production bases described above may be broadly any bases where the objects to be transported are prepared and collected, and include so-called collection / delivery centers and distribution centers. In this case, the production base terminal 2 of the embodiment is understood as a base terminal. The base terminal need not be a dedicated terminal as long as the functions described in the embodiment can be realized. Further, the base terminal only needs to be able to input and transmit base information, and does not need to be installed at the base, and a base terminal having the function may be prepared in any place. The functions of the base terminals may be distributed and arranged.

Transportation vehicles are not limited to automobiles, but include all vehicles that can transport goods, such as railway vehicles, railway wagons, ships, and airplanes. However, it is assumed that a relatively low-speed and low-cost transportation route and a relatively high-speed and high-cost transportation route can be selected.

The in-vehicle device 3 is not limited to a dedicated device, and may be a tablet device, a mobile terminal device, a PDA (Personal Data Assistant) or the like. In addition, the in-vehicle device 3 is transmitted and notified of the determination result as to whether or not to use the road for exclusive use of the automobile, but is displayed on the display device installed at the base, or notified to the driver's mobile terminal by e-mail. Alternatively, the notification may be made by using a voice telephone, SNS, or the like. The notification method itself is arbitrary.

製品 Product information indicating product specifications is broadly understood as transport object information indicating transport object specifications.

生産 Production plan information is generally understood to correspond to preparation plan information indicating a preparation plan for preparation including manufacturing, production, packing, transport to a warehouse, etc. of an object to be transported.

The product completion time information is generally understood as completion time information indicating the time when preparation for transportation of the object to be transported is completed. The timing at which the person in charge inputs the completion time information to the base terminal may be when the transportation object is actually prepared, or when the time when the transportation object can be prepared is determined.

The production performance difference is generally understood to correspond to the performance difference that is the difference between the latest time when the preparation of the transportation object indicated by the completion time information is completed and the scheduled completion time in the preparation plan.

Berth means a wide space that can be loaded and unloaded at the base.

In the above-described embodiment, the predicted volume is the predicted volume and the predicted floor area. However, the predicted volume is not limited to the volume and the floor area. For example, the height after stacking of products produced on the day at the production site is set as the predicted volume. Further prediction may be made. Moreover, it is also possible to make a physical quantity into a weight.

In the above embodiment, the use road determination unit 17 determines whether or not there is a timing when the predicted volume after the time when the target transport vehicle arrives exceeds the set volume or when the predicted floor area exceeds the set floor area. . However, the threshold used as a criterion for determining whether or not the predicted quantity has been exceeded is not limited to the upper limit of the quantity of products that can be stored, but can be set by the user to any value that is less than or equal to the upper limit of the quantity of products that can be stored May be.

In the above embodiment, when there is a timing when the predicted amount exceeds the threshold, and the berth of the next base is vacant at the predicted arrival time when using a motorway for transportation to the next base, It was decided that the road for exclusive use of the car should be used or should be used for transportation to the next base. However, the route may be determined to be changed or changed in consideration of other conditions such as a transportation cost and a time zone in which the traffic is congested, without being limited to an automobile-only road. That is, the berth of the next base is vacant or the waiting time is below the reference time at the predicted arrival time when a predetermined condition is satisfied and another route including an automobile-only road is used to the next base If a predetermined criterion such as is satisfied, it may be determined that another route including an automobile road is used or should be used for transportation to the next base.

In the above embodiment, an example is shown in which the quantity is predicted in units of days. However, the quantity may be predicted in units of shorter unit times, for example, 12 hours, 8 hours, or the like. Similarly, a longer time may be used as the unit time.

In the above embodiment, the case where the position information is latitude / longitude information has been described. However, the position information in the present invention may be information indicating the position of the transport vehicle that can be acquired by the in-vehicle device 3.

In the above embodiment, the completion time information, the vehicle state information, the latitude / longitude information, the predicted volume floor area information, and the berth use state information include the item “date”, but the transportation management device 1 includes a timer, When the date of the current day is held, the item of “date” may not be included in these pieces of information.

In the above-described embodiment, the description has been made on the assumption that the driver of the transportation vehicle always inputs the state of the transportation vehicle to the in-vehicle device 3 when the state of the transportation vehicle changes. However, since there is a possibility that the driver forgets to input the state of the transportation vehicle to the in-vehicle device 3, the transportation management device 1 detects the occurrence of the forgetting input, determines the state of forgetting the input, and determines the vehicle state information. You may make it the structure updated. In this case, the base information includes information indicating the berth area of the base. When the state of the transport vehicle indicated by the vehicle state information remains “moving” and the position of the transport vehicle indicated by the latitude / longitude information continues for a predetermined time, the transport management device 1 Forgetting to input “operation” is detected, and vehicle state information indicating the “operation” state of the transport vehicle is recorded. If the state of the transport vehicle indicated by the vehicle state information remains “work” and the position of the transport vehicle indicated by the latitude / longitude information continues for a predetermined time, the transport management device 1 Forgetting to input “movement” is detected, and vehicle state information indicating the “movement” state of the transport vehicle is recorded.

The transportation management device 1 is the time when the state of the transport vehicle indicated by the latitude / longitude information is in a position other than the berth in the location of the base while the state of the transport vehicle indicated by the vehicle state information remains “moving” If it is continued, forgetting to input “standby” is detected, and vehicle state information indicating the “standby” state of the transport vehicle is recorded. When the state of the transport vehicle indicated by the vehicle state information remains “standby” and the position of the transport vehicle indicated by the latitude / longitude information continues for a predetermined time, the transport management device 1 Forgetting to input “operation” is detected, and vehicle state information indicating the “operation” state of the transport vehicle is recorded.

If the transportation vehicle state indicated by the vehicle state information remains “moving” and the position of the transportation vehicle indicated by the latitude / longitude information does not change for a time determined at a position other than the location of the base, the transportation management device 1 performs “rest”. Is detected, and vehicle state information indicating the “rest” state of the transport vehicle is recorded. When the state of the transportation vehicle indicated by the vehicle state information remains “rest” and the position of the transportation vehicle indicated by the latitude / longitude information is changed for a predetermined time, the transportation management device 1 Forgetting to input is detected, and vehicle state information indicating the “moving” state of the transport vehicle is recorded.

In the above embodiment, the arrival / departure time prediction unit 15 determines whether or not vehicle state information indicating “work” of the target transport vehicle is recorded in the transport-related storage unit 13 in the arrival / departure time prediction process. However, when the base information includes information indicating the berth area of the base, the arrival / departure time prediction unit 15 determines that the target transport vehicle is within the berth based on the latitude / longitude information stored in the transport-related storage unit 13. You may determine whether it entered. In this case, when the departure / arrival time prediction unit 15 determines that the target transport vehicle has entered the berth, the same transport as the target transport vehicle at the same base based on the past vehicle state information, the past latitude / longitude information, and the base information. An average work time when the vehicle state is “work” is calculated.

In the above-described embodiment, the arrival / departure time prediction unit 15 determines whether the transport vehicle is in a working, moving, standby, or resting state based on the vehicle state information. Not only this but the departure / arrival time estimation part 15 may discriminate | determine the state of a transport vehicle based on position information. In this case, the arrival / departure time prediction unit 15 determines “work” based on the position information when the transport vehicle is stopped within the base berth. When the transport vehicle is stopped outside the location of the base, it is determined as “rest”. When the transport vehicle is stopped outside the berth in the location of the base, it is determined as “standby”. If the transport vehicle is moving, it is determined as “moving”.

In the above-described embodiment, the operation plan information is stored in advance in the transportation management apparatus 1 and is input by the user into the transportation management apparatus 1 or acquired by the transportation management apparatus 1 from an external server. Not limited to this, the transport management device 1 determines an operation plan based on the adjustment time calculated by the volume floor area prediction unit 14, the state of each transport vehicle, latitude / longitude information, load information, base information, etc. Operation plan information may be created. Specifically, the transportation management device 1 determines the lot of a product to be completed at the adjustment time calculated by the volume floor area prediction unit 14 based on the state of each transportation vehicle, latitude / longitude information, loading information, base information, and the like. The transportation destination, transportation vehicle, transportation date and time are determined, and operation plan information is created. In this case, the transport-related storage unit 13 may not store the operation plan information. The arrival / departure time prediction unit 15 may determine an operation plan based on the adjustment time calculated by the volume floor area prediction unit 14, the state of each transport vehicle, latitude / longitude information, load information, base information, and the like. . In this case, the arrival / departure time prediction unit 15 sets “estimated arrival time” to the production base of the target transport vehicle in the operation plan, “scheduled departure time” from the production base, and “scheduled arrival time” to the next base, respectively. The operation plan information is created using the time of the latitude / longitude information indicating that the target transport vehicle has arrived at the production base, the predicted departure time, and the predicted arrival time.

In the above-described embodiment, the use road determination unit 17 determines, for the target transport vehicle that has arrived at the production base, the timing when the predicted volume after the time of arrival at the production base exceeds the set volume or the predicted floor area exceeds the set floor area. If there is a timing, if the berth of the next base is vacant at the predicted arrival time when the car-only road is used, it is determined that the car-only road is used for movement to the next base. Not limited to this, for transport vehicles that have arrived at a base other than the production base, if the next base is a production base, the transport vehicle will be the target transport vehicle. If there is a timing when the floor area exceeds the set floor area, if the berth of the next production base is vacant at the estimated arrival time when using the automobile exclusive road, the automobile exclusive road is used to move to the next production base. Then, it may be determined. In other words, it may be determined whether or not to use the automobile road not only for movement from the production base to the next base but also for movement from other bases to the production base. In this case, the use road determination process is a process in which step S42 and step 43 are omitted from the flowchart shown in FIG.
