If the corresponding data exists, the information reception / transmission unit 22 transmits the data to the transportation plan support device 10. When the corresponding data does not exist, that is, when it is necessary to newly acquire the transportation information, the transportation information acquisition unit 21 is used to acquire the transportation performance information and accumulate it in each data table of the information storage unit 23, The data is transmitted to the transportation plan support device 10.

Next, the information receiving / transmitting unit 33 performs the same processing as the information receiving / transmitting unit 22, and the information storage unit 34 has an operation result (plan) data table (FIG. 4, 9100), an inventory result (plan) data table ( 6 and 9300) and the inventory entry / exit actual (plan) data table (FIGS. 7A and 9400). If the corresponding data exists, the information receiving / transmitting unit 33 transmits the data to the transportation plan support device 10. If the corresponding data does not exist, the newly acquired data using the inventory information acquisition unit 31 and the operation information acquisition unit 32 is transmitted to the transportation plan support device 10.

Next, regarding the information on the weather forecast and the weather results, the processing control unit 700 accesses the system in which the information receiving / transmitting device 18 publishes the information via the Internet, and acquires and acquires the corresponding information. Data is accumulated in a weather performance (forecast) data table (9500) of the data storage unit 900.

The details of the data acquired by this process will be described. In the present embodiment, the same data table is used as the actual data table and the plan (including forecast) data table, but different additional information may be provided.

In the present embodiment, among the data tables stored in the data storage unit 900, the data tables acquired from the information storage unit 23 and the information storage unit 34 are in the same format as the data storage unit 900, respectively. The information is stored in the information storage unit 34, but the information storage unit 23 and the information storage unit 34 may include other information.

Returning to the flowchart of FIG. 3, next, the data of inventory demand, inventory, inventory loading / unloading, and transportation whose plan is changed is extracted (S2000). In this processing, the plan change extraction unit 200 performs the following processing while the processing control unit 700 performs control so that the processing is executed without omission for each base, product, and ship.

FIG. 14 is a detailed flowchart of the processing performed in this processing step (S2000).

First, the latest demand forecast of each product is calculated from the latest operation result transition and the latest operation plan (S2100). For example, if the latest trends in operation results and the plan are both stable, the latest demand forecast for each product will be the same as before. In addition, when the operational performance itself is in a downward trend, or when the demand for the product decreases from the past trend independent of the operational performance (eg when the consumption efficiency of the product increases due to external factors), the latest The demand forecast will also be revised to a downward trend in line with past trends.

Next, the difference between the latest demand forecast calculated in the previous step (S2100) and the latest demand plan is calculated (S2200). In this process, the latest demand plan is acquired from the demand plan data table (9200) of the data storage unit 900, and subtraction is performed with the latest demand forecast calculated in the previous step (S2100). The result of this processing is stored in a temporary storage device or the like so that it can be used in later processing.

Next, calculate the degree of impact on the transportation lead time from the past transportation results and the weather results at the time of the transportation, and use the latest ship position, the latest transportation plan, and the latest weather forecast to operate the latest ship. A prospect is calculated (S2300). The calculation of the degree of influence on the transport lead time is realized, for example, by calculating the correlation between the wave height and the transport speed from the past transport record and the weather record during the transport. By using this result and the latest ship position, transportation plan, and weather forecast, it is possible to calculate the prospect of when each ship will arrive at each base in the future. For example, if the wave height is expected to be 1.5m when transporting from the base P to the base Q, and the past track record was likely to arrive one day late, The calculation is such that the forecast is one day later than the standard.

Next, the difference between the latest operation prospect calculated in the previous step (S2300) and the latest transportation plan is calculated (S2400). This process is basically based on the difference value from the latest plan such as “1 day delay” calculated in the previous step, but if a certain section is delayed by 1 day and the next section is 1 day early arrival, then For the section of, it is calculated that there is no change from the latest plan by offsetting the delay and early arrival. In this process, the offset process of the increase / decrease of the lead time in each section is mainly performed according to the transportation route.

Next, based on the difference between the demand plan calculated at step S2200 and step S2400 and the difference between the transportation plans, how much the inventory plan of each site / product is changed from the latest plan value is calculated (S2500). . Specifically, the difference in the demand plan is the difference in the inventory amount in the current inventory plan. For example, if the inventory plan on April 1, 2016 is 10 and the difference in the demand plan is −3, 10− ( −3) = 13 is a new inventory plan, and the change amount is +3. The difference in the transportation plan is the difference in the arrival date of the product. For example, the inventory plan on May 1, 2016 is 24, the inventory plan on May 2, 2016 is 20, and the original transportation plan is 2016. If the shipment arrives on May 2 and the quantity is 7 and the difference in the transportation plan is -1 day (1 day arrival), the stock plan on May 1, 2016 is 24 + 7 = 31, and the stock plan on May 2 of the same year A new inventory plan is calculated in the form of 20. Therefore, the change amount of the inventory plan is +7 on May 1, 2016, and is zero on May 2, 2016.

The inventory plan change content calculated in this step is stored in a temporary storage device or the like so that it can be used in subsequent processing.

Returning to the flowchart of FIG. 3, it is next determined whether or not all loads can be unloaded (S3000). In this process, the unloadability determination unit 300 performs the following process while the process control unit 700 performs control so that the process is executed without omission for all inventory plan changes.

FIG. 15 is a detailed flowchart of the processing performed in this processing step (S3000).

First, information that increases the change amount of the inventory plan is extracted from the plan change content calculated in the previous step S2500 (S3100). For example, information such as base: A, date and time: May 1, 2016, the change in inventory plan is +7 in the product XO33 is extracted.

Next, the amount of inventory change in all products is calculated at each site corresponding to the information calculated in the previous step S3100 (S3200). For example, when processing based on the information of the example described above, all the inventory change contents corresponding to the base: A, date and time: May 1, 2016 are acquired, and the inventory change amount included in the contents is extracted. Realize with.

Next, the difference of the stock storage required amount that increases or decreases based on the stock change amount of each product is calculated (S3300). This process can be executed using the inventory change amount of each product calculated in the previous step S3200 and the dimension information of the product that can be acquired from the product master information table of the data storage unit 900. For example, when the processing target product is XO33 and the inventory change amount is +7, the size of the product XO33 is 1000 × 100 × 100 from the product master information table. +7) = 700,000. In addition, when there are multiple target inventory change amount data, the difference between the inventory storage requirements based on the inventory change amount of each product is calculated by the method according to the above example, and all of them are totaled. The difference of the inventory storage required amount at the date and time of the base can be calculated.

Next, it is determined whether or not the difference of the inventory storage required amount does not exceed the inventory capacity of the base (S3400). This processing includes the stock storage area necessary amount difference value calculated in the previous step S3300, the stock storage space size information of the base, which can be acquired from the base master information table 9810 of the data storage section 900, and the data storage section. 900, the latest inventory plan data that can be acquired from the inventory entry / exit plan data table 9400, and the dimensional information of the product that can be acquired from the product master information table that the data storage unit 900 has. Is possible. For example, when the determination at the site: A and the date and time: May 1, 2016 is performed, the inventory storage size of the site A is acquired as 15000 × 7000 × 5000 from the site master information. Also, the stock storage required amount difference value is obtained as 700,000 from all steps, and the stock amount as of May 1, 2016 is determined from the stock amount included in the latest stock plan data and the product dimension information included in the product master information table. Assume that the capacity occupied by all stocks stored in the storage area is calculated as, for example, 1000000. In this case, the capacity occupied by the inventory including the inventory capacity = 15000 × 7000 = 105000000 and the inventory storage required amount difference value is calculated as 1000000 + 700000 = 1700,000, and the inventory capacity is larger than the capacity occupied by the inventory. Date: On May 1, 2016, it is determined that the inventory capacity is not exceeded.

The above processing is performed for all bases and all planned dates and times, and a judgment result is calculated as to whether inventory capacity will not be exceeded at each base and each date.

Finally, when it is determined that the inventory capacity is not exceeded at all sites, it is output that all unloading is possible, and when it is determined that the inventory capacity is exceeded even at one site / temporary point, it is output that some unloading is possible ( S3500). When the former output is obtained, the process proceeds to step S7000 in FIG. 3, and when the latter output is obtained, the process proceeds to step S4000 in FIG.

In this embodiment, the determination of the inventory capacity based on the area is described. However, for example, whether or not the inventory capacity is exceeded in a form including the inventory arrangement by reducing these series of processes to a planing problem. You may implement | achieve by the process which performs determination.

Return to the flowchart in FIG. Next, the demand priority of the stock product and the product scheduled to arrive at each base is calculated (S4000). In this processing, the demand priority calculation unit 400 performs the following processing while the processing control unit 700 performs control so that the processing is executed without omission for each site / product.

FIG. 16 is a detailed flowchart of the processing performed in this processing step (S4000).

First, the base and date / time information that is expected to exceed the inventory capacity is acquired (S4100). This process is realized by acquiring corresponding information from the result of step S3400 described above.

Next, all the products scheduled to be held as stock, including the unloading schedule, are extracted at each site / date corresponding to the information calculated in the previous step S4100 (S4200). This process can be executed by using the latest inventory plan data that can be acquired from the inventory storage / retrieval plan data table 9400 that the data storage unit 900 has. For example, when the base is A and the date and time is May 1, 2016, in the inventory storage / planning plan data table 9400, “base = A”, “storage date / time <May 1, 2016”, “shipping date / time” > May 1, 2016 ”is extracted, and the product name field of the record is extracted as a list.

Next, for the product calculated in the previous step S4200, a safety stock quantity is calculated based on the actual demand / demand forecast (S4300). This process can be acquired from the demand amount transition information that can be acquired from the demand record (plan) data table 9200 of the data storage unit 900 and the ship position record (plan) data table 9600 of the data storage unit 900. It is possible to execute using ship arrival information. For example, a past average daily demand amount and an average ship arrival time interval (unit: day) are calculated, and a value obtained by multiplying these two values is calculated as a safety stock amount.

Note that the method for calculating the safety stock amount described here is an example, and is not limited to this method. For example, it may be calculated based on the safety stock theory, or may be calculated using a ship arrival time interval plan value based on an actual transportation plan instead of using the average ship arrival time interval in the above description. In addition, although the unit of time is day here, it may be changed to hour unit or week unit according to the data granularity.

Finally, demand priority is calculated from the safety stock quantity and the inventory plan (S4400). This process can be executed using the safety stock amount calculated in the previous step S4300 and the stock amount plan information that can be acquired from the stock record (plan) data table 9300 that the data storage unit 900 has. As an example, the priority of demand at a certain product / date and time can be calculated by dividing the planned amount of inventory of the product / date and time by the safety stock quantity of the product / date / time. The calculation method of demand priority described in the present embodiment is not intended to be limited to this method. For example, when the demand amount of the product to be handled is not greatly different for each product, it is simply an inventory plan. A method of making the magnitude of the value a demand priority can also be adopted.

Referring back to the flowchart of FIG. 3, next, based on the priority of demand, a plan for which products to be placed in the inventory storage area of each base is calculated (S5000). In this process, the inventory storage plan calculation unit 500 performs the following process while the process control unit 700 performs control so that the process is executed without omission for each site / product.

FIG. 17 is a detailed flowchart of the processing performed in this processing step (S5000).

First, among the products held as inventory, the inventory storage space is allocated in descending order of demand priority (S5100). This process can be executed using the demand priority information for each product calculated in the previous step S4000 and the base / product master information possessed by the data storage unit 900. For example, first, the products scheduled to be held in the inventory storage area at the base / date are sorted in descending order of demand priority. Next, the area of the inventory storage area occupied by each product is calculated with reference to the product master information. Then, the sorted list of scheduled products to be acquired is acquired in order from the top within a range that does not exceed the stock capacity of the base that can be calculated from the base master information.

In this embodiment, the determination of the inventory capacity based on the area is described. However, for example, whether or not the inventory capacity is exceeded in a form including the inventory arrangement by reducing these series of processes to a planing problem. You may implement | achieve by the process which performs determination and produces | generates the inventory plan containing an inventory layout. In that case, instead of regenerating the plan for all products, the layout of the product that does not need to be changed is left as it is, and how to store the inventory in the free space for other products. It is also possible to adopt a method of calculating whether to allocate the.

Next, a product list that has not been allocated to the inventory storage space is acquired (S5200). This process can be realized by taking over the result of the previous step S5100 and extracting a product list that has not been acquired because the inventory capacity is exceeded.

Next, the location of each product acquired in the previous step (S5200) is confirmed (S5300). This processing can be executed by using the ship position plan (actual) data table 9600, the transport actual (plan) data table 9700, and the inventory storage / exit actual (plan) data table 9400 that the data storage unit 900 has. . For example, it is possible to determine whether each product acquired in the previous step S5200 is registered in the transportation performance (plan) data table 9700 or registered in the inventory storage / sales performance (plan) data table 9400. Note that there may be a case where the same product is being transported and is also kept in stock. In this case, it is confirmed that the product is registered in both tables.

If the location of the product is being transported in the previous step (S5300), it is confirmed whether or not there is a transit point where the ship carrying the product stops before coming to the destination of the product (S5350). . This processing can be executed using the ship position plan (actual) data table 9600 and the transportation plan (actual) data table 9700 that the data storage unit 900 has. For example, first, the ship on which the product is loaded is searched from the transportation plan (actual) data table. Next, it is searched from the ship position plan (actual result) data table which position the ship is navigating and what route is to be followed in the future. From this route search result, it is possible to determine whether or not there is a call to the relay point before arriving at the original destination of the product.

If it is output at step S5350 that there is a relay point, a plan is created for dropping the product at the relay point and temporarily placing it at the relay point (S5410). At a scheduled date and time when a ship carrying the product arrives at the relay site, processing for adding a warehousing plan for the product to the relay site is performed.

If the location of the product is output as inventory storage in step S5300, or if there is no transit point in step S5350, then the product is transferred and delivered to another site that requires the product. A plan to unload is made (S5420). For example, the presence / absence of another base that requires the product is determined by the magnitude of the priority of demand calculated in step S4400. Since a site with a high demand priority for the product can determine that the product is required, a process for transferring and delivering the product to the site and adding a warehousing plan for the product at the scheduled date and time when the ship arrives at the site is performed. Do. In addition, a plan for issuing the product is added to the inventory plan of the base serving as the transfer source.

Finally, if a product that cannot be temporarily placed or unloaded is generated, a plan to return it to the port is generated (S5500). For example, for a product that is subject to transfer but cannot be unloaded, add a plan to issue the product to the inventory plan of the base that will be the transfer source, and enter the port at the date and time of arrival at the port. The process of adding is performed.

As described above, in the present embodiment, the procedure in the flowchart shown in FIG. 17 has been described. However, due to the ease of execution for each of the transfer delivery to other bases, temporary placement at the relay site, and the priority order, It is possible to adopt a method that is realized after changing the processing procedure of each step. For example, as the second half of transportation, the loading capacity in the ship decreases, so even if the number of cases of returning to the port increases, it is easy to make a prospect that it can be handled. In that case, step S5420 is first executed, and only when a result that cannot be handled is generated, it is possible to examine a temporary placement plan at the relay point (execution of step S5410).

Referring back to the flowchart of FIG. 3, next, a product loading / unloading plan for each ship is calculated based on the inventory storage plan at each site (S6000). In this processing, the transportation plan calculation unit 600 performs the following processing while the processing control unit 700 performs control so that the processing is executed without omission for each base, product, and ship.

FIG. 18 is a detailed flowchart of the processing performed in this processing step (S6000).

First, the latest inventory storage plan created in the previous step S5000 is acquired (S6100).

Next, the latest loading / unloading plan for each product is generated based on the inventory storage plan (S6200). By referring to the inventory storage plan, it is possible to calculate the scheduled storage date and time of each product, and by using these date and time information, which products should be loaded and unloaded on which vessels Can be calculated.

Next, it is confirmed whether each ship is transported not exceeding the loading capacity (S6300). Based on the loading / unloading plan generated in the previous step S6200, the total volume and the total weight occupied by the products to be loaded are calculated at each time point, and these values are calculated from the ship master information possessed by the data storage unit 900. This can be achieved by checking whether the load capacity (volume / weight) is less than the actual capacity.

Finally, if there is a ship that has a transportation plan that exceeds the loading capacity, a plan to transport by subsequent transportation flights in order from the product with the lowest priority is generated (S6400).

3, the latest inventory / transportation plan is registered based on the plan calculation result and the change result (S7000). In this process, the latest planned calculation result is registered in each result (plan) data table of the data storage unit 900 while performing control so that the processing control unit 700 handles all the calculation results without omission.

Finally, the latest inventory / transport plan is transmitted to each base / ship, and the operation execution content is changed (S8000). In this process, the process control unit 700 performs control so that all the latest plan information is transmitted to each base / vessel without omission, while the information receiving / transmitting device 18 included in the transportation plan support apparatus 10 and the vessel The latest plan information stored in the data storage unit 900 is transmitted to each ship / base through the information reception / transmission unit 22 of the information collection device 20 and the information reception / transmission unit 33 of the base information collection device 30. To do.

The ship information collection device 20 and the base information collection device 30 that have received the latest plan register the information in the

information storage units

23 and 34, and the plan contents are the navigation information of the vessel, the on-site transportation information in the inventory storage area, the vessel. Convert to operation information for loading / unloading to / from the site, and change the operation execution contents.

In the operation at each ship / base, when the work instruction is digitized, the change in the operation execution content can be automatically made the latest work instruction as it is.

As described above, a new transportation plan can be created by performing all of the series of processes shown in FIG. The implementation of this process may be realized by, for example, determining in advance to be performed periodically (daily) in advance, and controlling the process control unit 700 to execute a series of processes on a daily basis, It may be realized by accepting a change request from the person in charge who manages each base, ship, and entire transportation as an input, and in response to this input, the processing control unit 700 starts a series of processes. In addition, an information receiving / transmitting device and information acquisition device that realizes real-time acquisition of information on each base and ship are provided, and the processing control unit 700 starts a series of processing as soon as a deviation from various plans occurs.
