A processing program 100, an inventory information database (DB) 110, a delivery plan DB 120, and a base information DB 130 are recorded in the storage 30D of the present embodiment.
The processing program 100 is an example of a transportation management program, and is a program for realizing each function of the center server 30.
The inventory information DB 110 is a database that stores inventory information of products. The inventory information DB 110 stores information on the amount of inventory for each product as the inventory information.
The delivery plan DB 120 is a database that stores the delivery plan of the product for the vehicle 12. The delivery plan DB 120 stores, for example, information on a vehicle for transporting the product, a date and time of transportation, a product to be transported, a manufacturer of the product, and a transportation destination of the product, as a delivery plan.
The base information DB 130 is a database that stores information on the base related to transportation of the product. The base information DB 130 stores, for example, information for identifying the base, information on the type of the base, and information on the location of the base as the information on the base.
The acquisition unit 200 acquires the information recorded in the inventory information DB 110, the delivery plan DB 120, and the base information DB 130.
The generation unit 210 uses the information acquired by the acquisition unit 200 to generate information to be notified to the vehicle 12. Specifically, the generation unit 210 generates information for causing the vehicle 12 to transport the product from the manufacturer of the product to the transportation destination. Also, the generation unit 210 generates information for instructing the vehicle 12 that has transported the product to the transportation destination to transport the article related to the product from the transportation destination to the manufacturer based on a demand for the article. The transportation destination to which the product is transported is located between the manufacturer that manufactures the product and the supplier of the material used for manufacturing the product. The transportation destination is a facility that temporarily stores the product transported from the manufacturer and a facility that temporarily stores the material transported from the supplier of the material.
Further, the generation unit 210 generates a delivery plan for the vehicle 12 to transport the article related to the product from the transportation destination to the manufacturer. For example, the generation unit 210 manages the inventory of the article of the manufacturer based on the demand information of the product, and generates a delivery plan of the article from the transportation destination to the manufacturer, as needed. The vehicle 12 uses a common transportation body such as a container or a pallet when transporting a part from the manufacturer of the product to the transportation destination and when transporting the article from the transportation destination to the manufacturer.
For example, the generation unit 210 may manage the inventory of the article of the manufacturer based on the demand information obtained based on vehicle malfunction information, and may generate the delivery plan of the article from the transportation destination to the manufacturer, as needed. The vehicle malfunction information may be acquired by the acquisition unit 200 from each vehicle, for example, through the execution of a self-diagnosis function of each vehicle. When the demand for a specific product is expected to increase based on the vehicle malfunction information, the generation unit 210 may generate a delivery plan for transporting the material used for the product to the manufacturer.
For example, the generation unit 210 may manage the inventory of the article of the manufacturer based on the demand information obtained based on weather information, and may generate a delivery plan of the article from the transportation destination to the manufacturer, as needed. For example, when it is found that it will snow in a few days ahead as a result of referring to the weather information, the generation unit 210 may generate a delivery plan of products that are often used during snowfall such as tire chains or studless winter tires.
For example, the generation unit 210 may manage the inventory of the article of the manufacturer based on the demand forecast for the article itself used for the product, and may generate a delivery plan of the article from the transportation destination to the manufacturer, as needed. By managing the inventory of the article based on the demand forecast for the article itself used for the product, the center server 30 can make an instruction to transport the article, for which demand is expected to increase, from the transportation destination to secure the article. The center server 30 can improve the efficiency of transportation by the vehicles 12 by making an instruction to transport the article, for which demand is expected to increase, from the transportation destination to secure the article.
The notification unit 220 notifies the on-board device 20 of the target vehicle 12 of the information generated by the generation unit 210 through the network N. When the on-board device 20 receives the notification, the CPU 20A of the on-board device 20 displays on the monitor 27 the information based on the received notification.
Next, the flow of control by the center server 30 will be described.
The CPU 30A acquires the inventory information of the product from the inventory information DB 110 (step S101).
Following step S101, the CPU 30A acquires information on the delivery plan of the product for which the inventory information was acquired in step S101, from the delivery plan DB 120 (step S102).
Following step S102, the CPU 30A acquires the delivery information of the product for which the inventory information was acquired in step S101 (step S103). The delivery information of the product is, for example, information indicating which product was delivered, and when, from where, to where, and how much the product was delivered.
Following step S103, the CPU 30A updates the information on the delivery plan of the product using the acquired delivery information of the product (step S104).
Following step S104, the CPU 30A notifies the vehicle 12 that transports the product of a product transportation instruction based on the information on the delivery plan of the product updated in step S104 (step S105). Upon receiving the notification from the center server 30, the driver of the vehicle 12 loads the product on the vehicle 12 based on the notification and the product is transported from the manufacturer (for example, the factory of the product) to the transportation destination (for example, the distribution center where the product is temporarily stored).
Following step S105, the CPU 30A determines whether the vehicle 12 has arrived at the transportation destination of the product (step S106). The CPU 30A may determine whether the vehicle 12 has arrived at the transportation destination of the product, based on the position information acquired by the GPS device 29 of the vehicle 12, for example.
When the CPU 30A determines that the vehicle 12 has not arrived at the transportation destination of the product (step S106; No), the CPU 30A repeats the process of step S106 until the vehicle 12 arrives at the transportation destination of the product.
When the CPU 30A determines that the vehicle 12 has arrived at the transportation destination of the product (step S106; Yes), the CPU 30A instructs the vehicle 12 that has finished transporting the product to load the material at the transportation destination based on the demand for the material (step S107). The material for which instruction of loading is made in step S107 is a material used for manufacturing the product at the manufacturer of the product.
Following step S107, the CPU 30A instructs the vehicle 12 on which the material is loaded to transport the material to the manufacturer (step S108).
The center server 30 executes a series of processes shown in
The transportation management method performed by the center server 30 will be described with reference to
The vehicle 12A that has transported the product from the manufacturer 501 to the transportation destination 502 based on the instruction from the center server 30 receives an instruction from the center server 30 to load the material at the transportation destination 502 and move to the manufacturer 501. The vehicle 12A transports the material loaded at the transportation destination 502 to the manufacturer 501 based on the instruction from the center server 30.
In this way, by causing the vehicle 12A to transport the product from the manufacturer 501 to the transportation destination 502 and instructing the same vehicle 12A to transport the article related to the product from the transportation destination 502 to the manufacturer 501, it is possible to improve the efficiency of transportation by the vehicle 12 compared with the case where such an instruction is not made. Further, by instructing the vehicle 12A to transport the article related to the product from the transportation destination 502 to the manufacturer 501, it is possible to transport the article by the vehicle 12A when necessary and only as necessary.
On the return route to the manufacturer after transportation of the product, it is conceivable that there is no article that should be transported from the transportation destination to the manufacturer. When there is no such article, the center server 30 may make an instruction that the transportation of the article is unnecessary to the vehicle 12 that has transported the product. That is, the center server 30 may instruct the vehicle 12 that has transported the product to return from the transportation destination to the manufacturer without loading anything. The center server 30 instructs the vehicle 12 that has transported the part to return from the transportation destination to the manufacturer without loading anything when there is no article that should be transported after the transportation of the product, so that the vehicle 12 can immediately return to the manufacturer, which can improve the efficiency of transportation by the vehicle 12.
Further, when there is no article that should be transported from the transportation destination to the manufacturer on the return route to the manufacturer after the transportation of the product, the center server 30 may instruct the vehicle 12 to transport the product to the delivery destination of the product without making a stop at the transportation destination. The vehicle 12 additionally transports the product from the transportation destination to the delivery destination, so that the efficiency of transportation can be further improved.
In the above embodiment, the transportation destination is located between the supplier of the article and the manufacturer of the product, and is a facility that temporarily stores the article and a facility temporarily stores the product. However, the present disclosure is not limited to such an example. The transportation destination may be the manufacturer of the article.
It should be noted that various processors other than the CPU may execute the transportation management process that is executed by the CPU reading the software (program) in each of the above embodiments. Examples of the processors in this case include a programmable logic device (PLD) such as a field-programmable gate array (FPGA) for which a circuit configuration can be changed after production, a dedicated electric circuit that is a processor having a circuit configuration designed exclusively for executing a specific process, such as an application specific integrated circuit (ASIC), and the like. In addition, the transportation management process may be executed by one of these various processors, or a combination of two or more processors of the same type or different types (for example, a combination of FPGAs and a combination of a CPU and an FPGA, and the like). Further, the hardware structure of these various processors is, more specifically, an electric circuit in which circuit elements such as semiconductor elements are combined.
Further, in each of the above embodiments, the mode in which the program of the transportation management process is stored (installed) in the ROM or the storage in advance has been described, but the present disclosure is not limited to this. The program may be recorded on a non-transitory recording medium such as a compact disc read-only memory (CD-ROM), a digital versatile disc read-only memory (DVD-ROM), and a universal serial bus (USB) memory to be provided. Further, the program may be downloaded from an external device via a network.
