Description

The present invention relates to a ready-mixed concrete shipping planning method, a shipping planning device, and a shipping planning system.

In concrete placement at the construction site, the construction site (construction staff, etc.) can secure the supply of ready-mixed concrete by ordering ready-mixed concrete from the ready-mixed concrete plant, for example, by the day before the placement. ing. The contents of this order include the construction date, the arrival time of the transport vehicle (agitator truck), the composition of ready-mixed concrete, the quantity of ready-mixed concrete (total amount on the construction date), the dispatch pitch of the transport vehicle, and the like. At the ready-mixed concrete plant, measures are taken such as creating a schedule plan list based on the order details, adjusting the allocation of transport vehicles, and arranging a truck if there is a shortage of transport vehicles. Then, on the concrete placing date, the ready-mixed concrete plant manufactures the ready-mixed concrete and transports it to, for example, a plurality of construction sites based on the shipping plan list.

By the way, one ready-mixed concrete plant may receive orders for ready-mixed concrete from various construction sites on the same day. In addition, at a large-scale construction site, there are multiple construction areas that are far from each other, and it is possible that ready-mixed concrete can be ordered from multiple construction areas on the same day. Therefore, in the ready-mixed concrete plant, it is necessary to organize the orders received from such a plurality of construction sites and construction zones on the same day, create the above shipping plan list, and respond to the demands of each construction site and each construction zone.
However, in a ready-mixed concrete plant, for example, even if a shipping plan list is created according to the order up to the previous day, the order can be placed on the day of concrete placement (in the morning or after the start of concrete placement) due to circumstances such as the construction site. It is often possible that the content will be changed in a hurry, or that the placement schedule itself will be canceled in a hurry.
In addition, in outdoor concrete placing, it is often possible that the concrete placing time zone is changed or the placing is postponed due to sudden changes in the weather or the like.
Conventionally, the person in charge of shipping the ready-mixed concrete plant responds to the above-mentioned various changes, but in consideration of the manufacturing capacity of the ready-mixed concrete plant and the number of transport vehicles that can be arranged including the merchandise, for the changing order. It was extremely difficult to quickly create a ready-mixed concrete shipping plan.

Here, Patent Document 1 describes a ready-mixed concrete schedule management system that connects a manufacturer, a seller, and a consumer via the Internet. Specifically, in order to allow manufacturers and sellers to publish their own ordering information on the homepage and enable scheduled orders and scheduled inquiries by manufacturers, sellers and consumers who can browse and input on the Internet. It is equipped with a system for managing and certifying such as, an information writing and data collection system by a certified manufacturer, and a system for disclosing the collected data. The manufacturer can manage the schedule status, arrange the vehicle allocation, and manage the schedule on the day of shipment, the seller can manage the schedule status and manage the schedule on the day of shipment, and the consumer can view the manufacturer's schedule status. , Manufacturer scheduled order, manufacturer scheduled on the day of shipment can be confirmed.

On the other hand, Patent Document 2 describes a ready-mixed concrete delivery and placing management system in which both the ready-mixed concrete plant and the construction site can share the current situation. Specifically, it consists of a host computer equipped with a database and multiple communication devices that send data to the database and check the contents of the database. The database has at least the following contents, ready-mixed concrete. Delivery and placing management system, the contents are the specifications of ready-mixed concrete, the start time of kneading ready-mixed concrete, the order of shipment of ready-mixed concrete for transport vehicles loaded with ready-mixed concrete, the delivery time of ready-mixed concrete at the construction site, and construction work. Time to complete casting of ready-mixed concrete at the site, elapsed time from the start time of kneading ready-mixed concrete, the number of transport vehicles currently used for placing ready-mixed concrete, the number of transport vehicles during transport of ready-mixed concrete, and construction work. This is the cumulative total of ready-mixed concrete delivered at the site.

According to the ready-mixed concrete schedule management system described in Patent Document 1, an order can be placed on the Internet, and the order availability is immediately displayed to convey the order availability between the manufacturer, the seller, and the consumer. Can be done without a time lag. Further, according to the ready-mixed concrete delivery and placing management system described in Patent Document 2, since the construction site and the ready-mixed concrete plant are equipped with a common communication device, both can access the database via the communication device. The current status can be confirmed, and both parties can enter predetermined information into the database as needed.

The present invention is a ready-mixed concrete shipping planning method capable of promptly creating a ready-mixed concrete shipping plan for a variable order in consideration of the manufacturing capacity of the ready-mixed concrete plant and the number of transport vehicles that can be arranged. It is intended to provide a shipping planning device and a shipping planning system.

In order to achieve the above object, one aspect of the ready-mixed concrete shipping planning method according to the present invention is:
It is a ready-mixed concrete shipping planning method that accepts orders from multiple construction sites on the same day to one ready-mixed concrete plant and executes the ready-mixed concrete shipping plan for each construction site.
A registration process for registering required data including at least the construction date, the actual arrival time, the quantity of ready-mixed concrete, and the vehicle allocation pitch for transporting ready-mixed concrete, which are required by the construction site.
A vehicle allocation information setting process that sets the production start time of the ready-mixed concrete based on the required data, and sets the production start time and the actual arrival time corresponding to each vehicle allocation number.
A calculation process for calculating the production speed of the ready-mixed concrete and the number of transport vehicles for each production start time.
A determination step for comparing the calculated manufacturing speed and the number of vehicles with respect to the first threshold value for the manufacturing speed and the second threshold value for the number of vehicles to be transported.
It is characterized by having a display step of displaying that there is nonconforming required data when the calculated manufacturing speed and the number of vehicles to be carried exceed either the first threshold value or the second threshold value. And.

According to this aspect, the required data from the construction site is registered in the registration process, and the dispatch number of the transport vehicle corresponding to the production start time of ready-mixed concrete is set in the vehicle allocation information setting process based on the required data. After the production speed of ready-mixed concrete and the number of transport vehicles are calculated for each production start time in the calculation process, these production speeds and the number of transport vehicles are within the production capacity range of the ready-mixed concrete plant and within the range that can be dispatched. It is determined in the determination process whether or not there is. Then, by displaying the determination result in the display process, it is possible to promptly recreate the shipping plan for the changing order and promptly inform the construction site whether or not the ready-mixed concrete can be supplied. ..

Further, one aspect of the ready-mixed concrete shipping planning device according to the present invention is.
It is a shipping planning device that accepts orders from multiple construction sites on the same day to one ready-mixed concrete plant and executes the shipping plan of ready-mixed concrete for each construction site.
A data registration unit that registers required data including at least the construction date, the actual arrival time, the quantity of ready-mixed concrete, and the vehicle allocation pitch for transporting ready-mixed concrete, which are required by the construction site.
A vehicle allocation information setting unit that sets the production start time of the ready-mixed concrete based on the required data, and sets at least the corresponding production start time and the actual arrival time for each vehicle allocation number.
A calculation unit that calculates the production speed of the ready-mixed concrete and the number of vehicles to be transported for each production start time.
A determination unit for comparing the calculated manufacturing speed and the number of vehicles with respect to the first threshold value for the manufacturing speed and the second threshold value for the number of vehicles to be transported.
In the determination unit, when the calculated manufacturing speed and the number of vehicles to be carried exceed either the first threshold value or the second threshold value, the first display unit displays that there is nonconforming required data. And, characterized by having.

According to this aspect, the request data from the construction site is registered in the data registration unit, and based on the request data, the vehicle allocation number corresponding to the ready-mixed concrete manufacturing start time is set in the vehicle allocation information setting unit and calculated. After the production speed and the number of transport vehicles of ready-mixed concrete are calculated for each production start time in the department, are these production speeds and the number of transport vehicles within the production capacity range of the ready-mixed concrete plant and within the range that can be dispatched? Whether or not it is determined by the determination unit. Then, by displaying the judgment result on the first display unit, it is possible to promptly recreate the shipping plan for the changing order and promptly inform the construction site whether or not the ready-mixed concrete can be supplied. Can be done. In the shipping planning device of this embodiment, the judgment unit determines each time the data content of the already approved request data is changed (change of concrete amount at predetermined time, change of construction date, etc.) or registration of new request data is accepted. The decision is made and a new shipping plan list is created.

Here, the shipping planning device of this embodiment is configured by a computer, for example, is installed in a ready-mixed concrete plant, and user terminals provided by construction personnel at a plurality of construction sites are freely accessible via a network. When the manufacturing speed, etc. calculated by the shipping planning device exceeds the threshold (first threshold, second threshold), it is determined that the data is incompatible and approval cannot be obtained (it is not reflected in the shipping planning list). Therefore, it can be said that the request data registered in the data registration unit is in the state of temporary registration, and when the judgment unit determines that the request data is suitable, the request data is officially registered from the temporary registration. Will be reflected in the shipping plan list.

For example, if there is a time zone that exceeds the manufacturing capacity of the ready-mixed concrete plant in the request from one construction site, the fact that the request data for that time zone is incompatible is displayed on the first display unit. , The data registration unit executes a process of not officially registering all or part of the requested data from the construction site (only in the non-conforming time zone). It is determined that the construction staff at the construction site who confirmed the contents of the first display unit will re-register the change request data with the contents such as changing (reducing) the required concrete amount in the non-conforming time zone. The rejudgment is executed in the section. Then, when the newly applied change request data is determined to be conform by the determination unit, the change request data is approved and officially registered in the data registration unit. Then, a new shipping plan list including the approved change request data is created and displayed on the first display unit. At the time of this re-registration, the construction staff at the construction site where the change request data is approved may request another ready-mixed concrete plant to reduce the required concrete, or place the reduced amount of concrete on another day. Take the measures of.
A shipping plan list is created each time the order status is changed, and the latest shipping plan list is displayed on the first display, so that the person in charge of construction at each construction site planning to place an order for the target ready-mixed concrete plant. By checking the latest shipping plan list displayed on the first display unit, the person, etc. can foresee the approval possibility of the request data for which the application is being considered.

Further, in another aspect of the shipping planning device according to the present invention, in the data registration unit, when there are request data from a plurality of the construction sites in the non-conforming request data, the construction is set in advance. Depending on the priority of the site, the registration of the request data of the construction site with the lower priority is canceled.
It also has a notification unit that notifies the user terminal of the construction site whose registration has been canceled that the registration of the request data has been canceled and that the change of the request data is urged.
After the change request data is registered in the data registration unit by the user terminal at the construction site whose registration has been canceled, the recalculation in the calculation unit and the re-judgment in the determination unit are executed, and the first threshold value and the first threshold are executed. When it is determined that both of the two thresholds are satisfied, the data registration unit approves the registration of the change request data, and the notification unit approves at least the change request data registration. It is characterized by notifying the user terminal of the construction site applying for.

According to this aspect, the requirement of the construction site with relatively high priority is maintained, or if the requirement is a later requirement, this requirement is approved, and instead, the requirement registered earlier is relatively prioritized. By canceling the registration of low-level requirements, the supply of ready-mixed concrete according to the priority of the construction site is realized. In addition to this, the user terminal at the construction site whose priority is relatively low and the registration of the request data has been canceled is urged to the effect that the registration of the request data has been canceled and to change the request data. By notifying the fact, it is possible to promptly take various measures such as considering orders to other ready-mixed concrete plants and considering changing the concrete placement date at the construction site where the registration has been canceled. Become.

Here, "cancellation of registration of request data" means that the request data has been approved once and officially registered, but is subsequently registered in response to a request from a relatively high-priority construction site. This includes both the cancellation of the request and the fact that the registration application is not approved because the request of the construction site with high priority has already been registered for the registration application of the current request data.
The priority of the construction site is set in advance between the ready-mixed concrete plant and, for example, a plurality of construction sites for ordering ready-mixed concrete from the ready-mixed concrete plant, and this priority is stored in the shipping planning device. There are various methods for setting the priority, and for example, the priority can be set based on the importance of the structure, the tightness of the construction period, and the like. Further, the priority once set may change according to the progress of construction at each construction site, and the priority may be reviewed periodically.

Further, another aspect of the shipping planning apparatus according to the present invention further includes a storage unit for storing a database containing the request data registered in the data registration unit.
The database includes a round-trip transportation time and a restraint time obtained by adding the waiting time and the unloading time at the construction site to the round-trip transportation time for each vehicle allocation number.
A margin coefficient is set based on the difficulty of placing concrete at the construction site, and a congestion coefficient is set based on the degree of traffic congestion during the transportation time zone.
The database is characterized in that the margin coefficient and the congestion coefficient are further included in the database as data for each vehicle allocation number, which is the assumed restraint time obtained by multiplying the restraint time.

According to this aspect, a restraint time including a round-trip transportation time is set for each vehicle allocation number, an estimated restraint time is set by multiplying the restraint time by a margin coefficient and a congestion coefficient, and an estimated restraint time for each vehicle allocation number is stored in the database. By storing it in the storage unit of the shipping planning device, it is possible to formulate a highly accurate shipping plan that takes into consideration both the difficulty of placing concrete and the degree of traffic congestion during the transportation time.

Here, the difficulty level of concrete placement at the construction site, which is the basis for setting the "margin coefficient", is the type of structure to be constructed (bridges, water and sewage, dams, buildings, condominiums, etc.) and the location conditions of the construction site. (There are restrictions on the casting location (concrete pump truck installation location) in urban areas, and multiple casting locations can be secured in the suburbs). For example, when the construction site is in the suburbs and the difficulty level of concrete placement such as water and sewage facilities that can secure multiple placement locations is set to "1", when concrete is placed at the construction site with this difficulty level "1". It can be said that it is not necessary to change (correct) the restraint time by the margin coefficient. On the other hand, even if the construction site is in the suburbs, if there are restrictions on the casting location, or if the construction site is in an urban area, "1.1", "1.2", etc. are set as the "margin coefficient". , The assumed restraint time is set longer than the restraint time.
On the other hand, the round-trip transportation time is specified in advance according to the transportation route between the ready-mixed concrete plant and the construction site and is included in the database, but even if the transportation route is the same, the time required for transportation varies depending on the transportation time zone. Therefore, it is decided to multiply the already specified round-trip transportation time by the "congestion coefficient" set according to the degree of congestion. For example, the time zone showing the average congestion status in a day is set to "1", and the congestion coefficient "1.1", "1.2", etc. is multiplied by the time zone that is more crowded. be able to.

Further, one aspect of the shipping planning system according to the present invention is
The shipping planning device installed on the ready-mixed concrete plant or the cloud,
It has a user terminal, which is connected to the shipping planning device so as to be able to send and receive data via a network.
The user terminal includes at least a second display unit, and the second display unit displays at least a determination result by the determination unit.

According to this aspect, for example, the shipping plan list and the judgment result by the judgment unit are displayed on the second display unit of the user terminal provided by the construction person in charge of a plurality of construction sites or the work place, so that the judgment result of each construction site is displayed. The person in charge of construction, etc. can refer to the displayed contents and promptly change the order of ready-mixed concrete (change the date and time, change the quantity, etc.) as necessary.
Here, the shipping planning device is composed of an information processing device such as a personal computer or a workstation (WS: Work Station), and the user terminal is composed of an information processing device such as a smartphone, a tablet, or a personal computer, all of which are configured by a computer. Will be done.
In addition, the shipping planning device may be installed in either the ready-mixed concrete plant or the cloud. When the shipping planning device is installed in the ready-mixed concrete plant, the person in charge of shipping the ready-mixed concrete plant can confirm the shipping plan list or the like on the first display unit of the shipping planning device. On the other hand, if the shipping planning device is on the cloud, for example, the shipping staff of the ready-mixed concrete plant is equipped with a user terminal in the same way as the construction staff at the construction site, and the shipping plan list etc. is confirmed on the second display unit. can do.

According to the ready-mixed concrete shipping planning method, the shipping planning device, and the shipping planning system of the present invention, the ready-mixed concrete plant can be quickly produced in consideration of the manufacturing capacity and the number of transport vehicles that can be arranged.

Hereinafter, the ready-mixed concrete shipping planning method, the shipping planning device, and the shipping planning system according to the embodiment will be described with reference to the attached drawings. In the present specification and the drawings, substantially the same components may be designated by the same reference numerals to omit duplicate explanations.

[Embodiment]
<Prepared concrete shipping planning system>
First, an example of a ready-mixed concrete shipping planning system according to an embodiment will be described with reference to FIG. Here, FIG. 1 is an overall configuration diagram showing an example of a ready-mixed concrete shipping planning system according to an embodiment.

In the ready-mixed concrete shipping planning system 50 shown in the figure, one ready-mixed concrete plant accepts orders from a plurality of construction sites, and the ready-mixed concrete plant takes into consideration its manufacturing capacity and the number of transport vehicles that can be arranged. It is a system that makes it possible for each construction site to create a shipping plan and check the created shipping plan list. When request data is received from multiple construction sites and the request data is approved, the shipping plan list is updated at any time, and each construction site can check the latest shipping plan list at the present time.

The shipping planning system 50 is formed by connecting a ready-mixed concrete shipping planning device 10 included in a ready-mixed concrete plant and a user terminal 20 provided by construction managers and the like at a plurality of construction sites via a network 30. The shipping planning device 10 is composed of an information processing device such as a personal computer (PC: Personal Computer) or a workstation (WS: Work Station), and the user terminal 20 is an information processing device such as a personal computer (PC: Personal Computer) or a tablet. It is a device, and each is composed of a computer.

The network 30 includes a public network such as the Internet, a wireless network such as a mobile phone network, a dedicated network such as a VPN (Virtual Private Network), a LAN (Local Area Network), and the like.

Access to the shipping planning device 10 requires access authority, and only the user terminal 20 to which the access authority is granted can access the shipping planning device 10 and apply for registration of request data. Although the illustrated example shows a form in which the shipping planning device 10 is provided in the ready-mixed concrete plant, the shipping planning device 10 may be provided on the cloud. In this case, the ready-mixed concrete plant is also the same as the construction site. Is equipped with a user terminal, and is configured as a system in which both the ready-mixed concrete plant and the construction site can view the processing contents of the shipping planning device 10.

When the request data is transmitted to the shipping planning device 10 by the user terminal 20 at the construction site, the shipping planning device 10 that has received the request data temporarily registers the request data, and the request data is the ready-mixed concrete plant. It is determined whether or not both the production capacity of the concrete and the thresholds of the number of transport vehicles that can be arranged (the first threshold and the second threshold) are satisfied. As a result of the judgment, when it is determined that both thresholds are satisfied, the provisional registration is approved and officially registered, and when it is determined that at least one of the thresholds is not satisfied, the provisional registration is not approved and the shipping plan. Data is transmitted from the device 10 to the user terminal 20 at the target construction site to notify that the registration (temporary registration) of the request data is not approved and that the change of the request data is urged.

The shipping plan device 10 creates and displays a shipping plan list for a certain day in the target ready-mixed concrete plant, and the user terminal 20 also displays the shipping plan list on the screen. It has become. In addition to the case where the request data is not approved, when the request data that has been approved once is canceled after the fact, the registration of the request data is canceled from the shipping planning device 10 to the user terminal 20. , And the data notifying that the request data is urged to be changed is transmitted, and the notification content is displayed on the screen on the user terminal 20. For example, request data from a relatively high-priority construction site is received after the fact and interferes with a part of the already registered request data of a relatively low-priority construction site (manufacturing capacity of ready-mixed concrete plant). Such an event can occur in the case of a request exceeding the above.

The user terminal 20 notified that the registration (temporary registration) of the request data has been canceled reiterates the change request data in which the content of the request data is changed, such as changing the order quantity in a certain time zone of the ready-mixed concrete on the day. You can apply for registration. When this change request data is approved, the fact that the change request data has been approved means that the user terminal 20 that is applying for re-registration of the change request data, or even another user terminal 20 (high priority). It is sent to the user terminal 20), the order for ready-mixed concrete is officially accepted, and the shipping plan list is updated.

<Prepared concrete shipping planning equipment>

The communication IF 14 is an interface with the network 30 to which the shipping planning device 10 and the like are connected. The communication IF 14 receives the request data from the user terminal 20 provided at each construction site via the network 30, and re-registers to the effect that the request data is approved for each user terminal 20 when the request data is not approved. Various data related to the fact that the registered request data has been canceled, the shipping plan list that is updated from time to time, etc. are sent.

The input / output IF 15 is an interface for inputting / outputting data to / from a device connected to the shipping planning device 10 or the like. For example, a keyboard, a pointing device such as a touch panel or a mouse, an input device such as a microphone, or the like is connected to the input / output IF15.

In the example shown in FIG. 4, when the construction person inputs the construction name, site number, composition (mixing of ready-mixed concrete), planned number of pitches, arrival time, etc., the input request data is input to the second communication unit 202. It is transmitted to the first communication unit 102 via.

When the request data is transmitted to the first communication unit 102, the number of transport vehicles (required number) required at each arrival / arrival time is calculated by the shipping planning device 10, and the calculated required number is displayed in the order table. It is automatically entered. For example, in the example shown in FIG. 4, since the transportation amount per carrier is 4 m ³ and the planned quantity of the order number 1 at the arrival time of 7:00 is 30 m ³ , the required number of vehicles is eight. It is indexed.

In the example shown in FIG. 4, a ready-mixed concrete plant (shipping factory A) is scheduled to ship 355 m ³ of ready-mixed concrete as an order list for one day, and the amount of ready-mixed concrete per carrier is 4 m. It is shown that the value is ³ and that the upper limit of the number of vehicles (second threshold value) is 25. In addition, even with the same construction name (construction site), since various structures are being constructed at locations far from each other, there are multiple construction zones (corresponding to the site numbers in Fig. 4) and each construction zone for each construction site. The type of structure to be constructed is displayed in. The structure numbers are assigned in advance to various structures such as bridge piers, abutments, underground pits, and cast-in-place piles, and a list of structures corresponding to the structure numbers (Fig.) (Not shown) can be referred to.

Since the construction difficulty level (difficulty level when placing concrete) differs depending on the structure type and the time required for concrete placement differs depending on the construction difficulty level, the margin coefficient is based on the difficulty level of the structure type. It is set and stored in the storage unit 116 as a margin coefficient chart (not shown). Here, the structural types include major classifications such as bridges, water and sewage facilities, buildings, and condominiums, as well as minor classifications such as piers and cast-in-place piles inside bridges, and the margin coefficient for each classification. Is set.

The data registration unit 104 temporarily processes the request data received by the first communication unit 102 as temporary registration data, and stores the request data temporarily registered in the storage unit 116.

The vehicle allocation information setting unit 106 sets the production start time of ready-made concrete based on the required data (current arrival time, ready-made concrete quantity, vehicle allocation pitch, etc.), and the corresponding production start time and actual arrival time for each vehicle allocation number. Is set, and a manufacturing / transportation characteristic table as shown in FIG. 5 is created.

In the example shown in FIG. 5, it is shown that the margin coefficients for all structures are 1.0, and therefore the difficulty of each structure is standard. Further, in the example shown in FIG. 5, the batch amount in the target ready-mixed concrete plant is 2 m ³ , the kneading takes 1 minute and 30 seconds, and the transport volume of one carrier is 4 m ^3. Therefore, the transport is carried out. It has been shown that one vehicle can carry two batches and that the upper limit (first threshold) of the production speed, which indicates the production capacity of the ready-mixed concrete plant, is 80 m ³ / hr.

The round-trip transportation time by the transport vehicle between each construction site and the ready-mixed concrete plant is specified in advance, and the round-trip time according to the construction name and site number that specify the construction site is stored in the storage unit 116. At this time, it is desirable to correct the round-trip transportation time according to the traffic congestion based on the round-trip transportation time in the time zone where the traffic congestion degree is standard in the day.

FIG. 6 is a diagram showing an example of a congestion coefficient chart stored in the storage unit 116. There is no need to correct the standard round-trip transportation time (multiply by 1), and the congestion coefficient for the busy time zone from 8:00 to 9:00 and the time zone from 16:00 to 18:00. Is 1.1. The round-trip time between the ready-mixed concrete plant and the construction site in each time zone may be specifically specified, and the specifically specified round-trip time may be input to the database. This form also has a congestion coefficient. It may be included in correcting the transportation time of each time zone from the transportation time of the reference time zone.

Returning to FIG. 5, the restraint time from the carrier leaving the ready-mixed concrete plant to returning to the ready-mixed concrete plant includes the waiting time at the construction site, the unloading time, and the washing time in addition to the round-trip transportation time. ..

Therefore, the vehicle allocation information setting unit 106 calculates the estimated restraint time by multiplying the above-mentioned restraint time by the above-mentioned margin coefficient and the congestion coefficient, and creates a database by setting the estimated restraint time for each vehicle allocation number. Will be done.

The calculation unit 108 calculates the production speed of ready-mixed concrete and the number of transport vehicles for each production start time. In this calculation, the number of vehicles that can be used at each time is appropriately reflected by including the vehicles that have returned from the construction site in the vehicles that can be used at any time. In addition, the production speed is calculated by dividing the production amount (shipment amount) that must be kneaded by a certain time by the elapsed time until the time.

The determination unit 110 determines the manufacturing speed and the number of vehicles to be transported calculated by the calculation unit 108 with reference to the threshold values (the first threshold value regarding the production speed and the second threshold value regarding the number of vehicles to be transported) stored in the storage unit 116. Compare.

FIG. 7 shows an example of a database including the determination result by the determination unit 110, and various data are shown according to the vehicle allocation number, and the data are sorted in the order of the earliest production start time. In FIG. 7, in the column of manufacturing speed and the column of the number of operating vehicles, the vehicles with diagonal lines in the cells are vehicles that do not satisfy at least one of the first threshold value and the second threshold value. Is shown.

FIG. 8 shows a graph of the results shown in FIG. 7 in an easy-to-understand manner. As is clear from FIG. 8, it can be seen that the current order status does not satisfy either the first threshold value or the second threshold value in the time zone from 6:00 to 9:00.

The database shown in FIG. 7 and the graph shown in FIG. 8 are displayed on the first display unit 112 of the shipping planning device 10 and also on the second display unit 204 of the user terminal 20 at the construction site.

Here, in the database shown in FIG. 7, since there is a time zone in which either the first threshold value or the second threshold value is not satisfied, it is necessary to improve the order status in this time zone.

In order to improve the order status, the order for the time zone to be improved is targeted depending on the case where the order is from only one construction site and the case where there are orders from multiple (for example, two) construction sites. The form of notification to the construction site is different.

In the former case, the notification unit 114 receives notification data to the effect that the target construction site does not approve the order for the time zone requiring improvement and to encourage the reduction of the order quantity in the time zone. It is transmitted to the user terminal 20 provided at the site.

On the other hand, in the latter case, the order for the user terminal 20 at the construction site, which has a relatively low priority, is canceled during the time period requiring improvement, according to the preset priority of the construction site. , Send notification data to urge the reduction of the order quantity in the time zone and the change of the order time zone or the order date. Here, there are various methods for setting the priority, and for example, the priority can be set based on the importance of the structure, the tightness of the construction period, and the like. Further, the priority once set may change according to the progress of construction at each construction site, and the priority may be reviewed periodically.

In any of the above cases, at the construction site where the notification data is received, the order quantity in the target time zone is changed, the order in the target time zone is canceled, and the order is changed to another time zone, etc. The change policy of the above is determined, and the change request data in which the request contents are changed is transmitted to the shipping planning apparatus 10 again. FIG. 9 is a diagram illustrating the change of the order, the upper figure is a diagram showing the order table before the change corresponding to FIG. 4, and the lower figure is a diagram showing the order table after the change.

Comparing the upper and lower figures, it can be seen that the arrival time of order number 5 in the middle row has been changed from 7:00 to 9:00. For this change, the person in charge of construction at the construction site refers to the graph shown in FIG. 8 displayed on the second display unit 204 of the user terminal 20, and there is a margin in manufacturing from around 9:00 to the time after that. After confirming that, the arrival time of order number 5 is changed from 7:00 to 9:00.

The shipping planning device 10 that has received this change request data sets the production start time and the actual arrival time for each vehicle allocation number in the vehicle allocation information setting unit 106, and the production speed and carrier of ready-made concrete for each production start time in the calculation unit 108. The calculation with the number, the comparison judgment between the manufacturing speed and the number of transported vehicles and the respective thresholds are executed again in the determination unit 110, and whether or not both the manufacturing speed and the number of transported vehicles satisfy the first threshold and the second threshold. To verify. As a result of the re-judgment, if both thresholds are satisfied, the change request data is approved, the shipping plan list is updated, and the request data is sent to the user terminal 20 requesting re-registration of the change request data. You will be notified that it has been approved. On the other hand, as a result of the re-judgment, if one of the threshold values is still not satisfied, the notification that the threshold value is not satisfied is notified again, and the construction site is urged to further change the change request data.

FIG. 10 is a diagram showing a shipping plan list in which all of the required data satisfies the threshold value and is approved by the shipping planning apparatus 10, and FIG. 11 is a graph of the shipping plan list shown in FIG. ..

For example, as is clear by comparing FIGS. 8 and 11, the shipping speed and the carrier vehicle are changed from 8:00 to 10:00 after the change, as opposed to the state before the change in which the threshold value was not satisfied around 8:00. The number of operating vehicles is equalized as much as possible, and both the shipping speed and the number of operating vehicles are satisfying the threshold.

According to the shipping planning system 50 equipped with the illustrated shipping planning apparatus 10, it is possible to accept a variable ready-mixed concrete shipping order based on the production capacity of the ready-mixed concrete plant and the number of transport vehicles that can be arranged. The sex can be determined quickly. Then, if it can be accepted, the ready-mixed concrete shipping plan list can be promptly created, and if it cannot be accepted, the change of the required data can be promptly notified to the construction site. Further, by the above determination by the shipping planning apparatus 10, it becomes possible to optimize the manufacturing and shipping in the ready-mixed concrete plant.

Next, the production start time of ready-mixed concrete is set based on the required data, and the corresponding production start time and actual arrival time are set for each vehicle allocation number. Based on this setting, the manufacturing / transportation characteristic table as shown in FIG. 5 is created.

In this manufacturing / transportation characteristic table, it is desirable to correct the operating time of the transport vehicle in consideration of factors such as construction difficulty and traffic congestion. Specifically, the margin set based on the difficulty of concrete placement at the construction site with respect to the round-trip transportation time and the restraint time of the transport vehicle including the waiting time, unloading time, washing time, etc. at the construction site. Calculate the estimated restraint time by multiplying the coefficient by the congestion coefficient set based on the degree of traffic congestion in the transportation time zone, and create a database in which the estimated restraint time is linked to each vehicle allocation number (above). , Vehicle allocation information setting process, step S304).

Next, the production speed of ready-mixed concrete and the number of vehicles to be transported are calculated for each production start time. In this calculation, the number of vehicles that can be used at each time is appropriately reflected by including the vehicles that have returned from the construction site in the vehicles that can be used at any time. Further, in the calculation method of the production speed, the production amount (shipment amount) that must be kneaded by a certain time is divided by the elapsed time until the time (the above is the calculation step, step S306).

Next, the calculated production speed of ready-made concrete and the number of vehicles to be transported are compared with those preset threshold values (first threshold value and second threshold value), and the corresponding threshold value of the production speed and the number of vehicles to be transported is determined. It is determined whether or not the condition is satisfied (determination step, step S308).

It is displayed on each display unit of (the above is the display process, step S310).

If the request data is not approved, the construction site that sent the request data is notified that the request data is not approved and that the request data is urged to be changed. In addition, if there are request data from multiple construction sites in the nonconforming request data, the request data of the construction site with low priority is registered according to the preset priority of the construction site. Perform a cancellation of. At this time, the user terminal 20 at the construction site whose registration has been canceled is notified that the registration of the request data has been canceled and that the change of the request data is urged.

The construction site where the request data is not approved or canceled after the fact applies for registration of the change request data whose request contents have been changed to the shipping planning device 10 again, and in the shipping planning device 10, from the registration process to the determination process. Execute a series of flows again. Then, as a result of the determination, if both the manufacturing speed and the number of vehicles satisfy the corresponding threshold values, the change request data is approved, and the latest shipping plan list reflecting the change request data is created. , The shipping plan list is displayed on each display unit of the shipping planning device 10 and the user terminal 20. Further, the user terminal 20 at the construction site where the application for registration of the change request data is permitted is notified that the change request data has been approved.

According to the illustrated shipping planning method, for a variable ready-mixed concrete shipping order, the acceptability of the order can be promptly determined based on the manufacturing capacity of the ready-mixed concrete plant and the number of vehicles that can be arranged. can. Then, if it can be accepted, the ready-mixed concrete shipping plan list can be promptly created, and if it cannot be accepted, the change of the required data can be promptly notified to the construction site. In addition, the determination process makes it possible to optimize manufacturing and shipping in the ready-mixed concrete plant.
