Description

[Technical Field]

[0001] The present disclosure relates to a ready-mix concrete ordering support device, a program, and a ready-mix concrete ordering support method. [Background technology]

[0002] Ready-mixed concrete solidifies over time after being shipped from a shipping plant. For this reason, the time allowed for transporting ready-mixed concrete to a delivery destination (allowable transport time) is set to, for example, 90 minutes. The purchaser (delivery destination of ready-mixed concrete) must find a shipping plant that meets the conditions, such as the allowable transport time. For example, Patent Document 1 discloses a ready-mixed concrete ordering system that connects purchasers and shipping plants to meet the conditions. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-007636 Summary of the Invention [Problem to be solved by the invention]

[0004] The system of Patent Document 1 executes an operation determination process to determine whether ready-mixed concrete can be shipped and delivered during operating hours. For example, with regard to transportation, the system of Patent Document 1 calculates the transportation time required for the outbound journey and compares it with the allowable transportation time to determine whether the transportation is possible or not. However, vehicles that transport ready-mixed concrete (so-called mixer trucks) are large, specialized vehicles that can only travel on limited roads. Therefore, accurate transportation times cannot be calculated using calculation methods designed for general vehicles. Furthermore, from the perspective of work efficiency, purchasers desire to be able to confirm in advance that delivery is possible before placing an order, without waiting for the system's determination results. Furthermore, the receiving party (shipping factory) may impose a surcharge if circumstances make it difficult to transport the product to the delivery destination. From the perspective of cost management, purchasers desire to be able to confirm whether a surcharge will be incurred before placing an order.

[0005] The purpose of the present disclosure, made in consideration of the above circumstances, is to provide a ready-mixed concrete ordering support device, program, and ready-mixed concrete ordering support method that can provide accurate information to the client. [Means for solving the problem]

[0006] (1) A ready-mixed concrete ordering support device according to an embodiment of the present disclosure is An acquisition unit that acquires past travel record data including the location and travel time of a transport vehicle that transports ready-mixed concrete from a shipping plant, and map information; a generating unit that generates an isotime line map from the shipping factory based on the map information and the driving performance data; and an output unit that outputs the isochrone diagram so that it can be used by a purchaser of the ready-mixed concrete. This configuration makes it possible to provide accurate information to the orderer.

[0007] (2) As one embodiment of the present disclosure, in (1), The generation unit sets a transportable area in the isochrone diagram to an area included within a range of an allowable transport time from the shipping factory. With this configuration, the orderer can easily check whether the item can be transported or not based on the isochrone diagram when placing an order.

[0008] (3) As one embodiment of the present disclosure, in (2), The generation unit sets the transportable area in the isochrone diagram to an area that is included within the range of the allowable transport time from the shipping factory and for which the probability of being able to reach the area based on the driving performance data is greater than or equal to a threshold. This configuration can increase the reliability of the determination of whether transport is possible or not based on the isochrone diagram.

[0009] (4) As an embodiment of the present disclosure, in (2) or (3), The generation unit sets a rescueable area on the isochrone diagram that is within a predetermined time range from the base of a rescue vehicle that will rescue the transport vehicle in the event of a breakdown, and sets the transportable area to an area that is within the allowable transport time range from the shipping factory and overlaps with the rescueable area. This configuration makes it possible to provide useful information to the purchaser while taking into consideration the risk of breakdown of the transport vehicle at the shipping factory.

[0010] (5) As an embodiment of the present disclosure, in (4), The generation unit sets a surcharge area in which a surcharge will be incurred in the area in the isotime line diagram that is included within the range of the allowable transportation time from the shipping factory and does not overlap with the rescue possible area. With this configuration, the ordering party can check whether or not a surcharge will be incurred based on the iso-time line diagram when placing an order.

[0011] (6) As an embodiment of the present disclosure, in any one of (1) to (5), The generating unit divides the travel time of the transport vehicle into a plurality of time periods and generates the isotime line map for each of the plurality of time periods. This configuration makes it possible to provide the client with more accurate information that takes into account traffic conditions for each time period.

[0012] (7) As an embodiment of the present disclosure, in any one of (1) to (6), When there are multiple shipping factories and the areas within the allowable transportation time from the shipping factories overlap, the generation unit generates an isochrone diagram by prioritizing the shipping factory that takes the shortest time to reach the overlapping areas. This configuration makes it possible to provide the orderer with more accurate information that takes into account shipments from multiple shipping factories.

[0013] (8) A program according to an embodiment of the present disclosure includes: Ready-mix concrete ordering support device, Acquiring past travel record data including the location and travel time of a transport vehicle that transports ready-mixed concrete from a shipping plant, and map information; generating an isotime line map from the shipping factory based on the map information and the driving performance data; and outputting the isochrone diagram so that it can be used by a purchaser of the ready-mix concrete. This configuration makes it possible to provide accurate information to the orderer.

[0014] (9) A ready-mixed concrete ordering support method according to an embodiment of the present disclosure includes: A ready-mixed concrete ordering support method executed by a ready-mixed concrete ordering support device, Acquiring past travel record data including the location and travel time of a transport vehicle that transports ready-mixed concrete from a shipping plant, and map information; generating an isotime line map from the shipping factory based on the map information and the driving performance data; and outputting the isochrone diagram so that it can be used by a purchaser of the ready-mix concrete. This configuration makes it possible to provide accurate information to the orderer. [Effects of the Invention]

[0017] A ready-mixed concrete ordering support device 10 (see FIG. 1), a program, and a ready-mixed concrete ordering support method according to one embodiment of the present disclosure will be described below with reference to the drawings. In each drawing, identical or corresponding parts are designated by the same reference numerals. In the description of this embodiment, the description of identical or corresponding parts will be omitted or simplified as appropriate.

[0018] 1 and 2 are diagrams showing an example of the configuration of a ready-mixed concrete ordering support system. The ready-mixed concrete ordering support system includes a ready-mixed concrete ordering support device 10. FIG. 1 is a block diagram including an example of the internal configuration of the ready-mixed concrete ordering support device 10. FIG. 2 shows the overall configuration of the ready-mixed concrete ordering support system.

[0019] The ready-mixed concrete ordering support device 10 according to this embodiment provides useful information to the orderer (the delivery destination of the ready-mixed concrete) to support the orderer in making efficient orders. Ready-mixed concrete solidifies over time after being shipped from a shipping plant. For this reason, the time allowed for transporting ready-mixed concrete to the delivery destination (allowable transport time) is set to, for example, 90 minutes. Therefore, being able to confirm that transport is possible and the exact transport time at the time of ordering is useful for efficient ordering (for example, without the hassle of inquiries, etc.). Details of the ready-mixed concrete ordering support system are described below. Here, the vehicle that transports ready-mixed concrete (the so-called mixer truck) is a large, special-purpose vehicle. In the following, the ready-mixed concrete ordering support system is described, with the mixer truck referred to as a "transport vehicle" and ordinary cars that are not mixer trucks referred to as "general vehicles."

[0020] The ready-mixed concrete ordering support device 10 includes a communication unit 11, a memory unit 12, and a control unit 13. The control unit 13 includes an acquisition unit 131, a generation unit 132, and an output unit 133. The ready-mixed concrete ordering support device 10 may be, for example, a computer as a hardware configuration. The computer may be a server computer or a portable computer such as a laptop or tablet. Details of the components of the ready-mixed concrete ordering support device 10 will be described later. In this embodiment, the ready-mixed concrete ordering support device 10 is a computer of an organization that provides support services for ready-mixed concrete ordering operations, and is capable of communicating with a terminal device 50 and a memory device 90. Here, the ready-mixed concrete ordering support device 10 may not be a single device, but may be composed of multiple devices located in multiple locations that can send and receive data to and from each other via a network 40. In other words, multiple devices connected via a network 40 may function as a whole as the ready-mixed concrete ordering support device 10 shown in FIG. 1. Therefore, for example, the ready-mix concrete ordering support device 10 may be configured as a hardware configuration consisting of one computer, or may be configured as multiple computers connected via a network 40. When configured as multiple computers, the storage unit 12 may be a shared memory that can be accessed by each computer.

[0021] The ready-mixed concrete ordering support device 10, together with a terminal device 50 connected via a network 40, constitutes a ready-mixed concrete ordering support system. The network 40 is, for example, the Internet. The network 40 may also be configured to include, for example, a local area network (LAN) in part. Here, the terminal device 50 is a device equipped with a display unit (display) used by the purchaser, and may be, for example, a laptop, a smartphone, or a tablet terminal, but is not limited to these. The terminal device 50 acquires an isochrone diagram output by an output unit 133, which will be described later. The display unit of the terminal device 50 displays the isochrone diagram to the purchaser.

[0022] Furthermore, the ready-mixed concrete ordering support system may be configured to include a storage device 90 (cloud-based storage device 90) on the network 40 as viewed from the ready-mixed concrete ordering support device 10 and the terminal device 50. In this embodiment, the storage device 90 includes a database that stores past driving performance data, including the location and driving time of a transport vehicle that transports ready-mixed concrete from a shipping plant, and map information. Here, there may be multiple shipping plants. Data such as the location of each transport vehicle is managed in association with the shipping plant from which the vehicle is shipped (e.g., whether the vehicle belongs to the first shipping plant or the second shipping plant) and the location of the shipping source (e.g., the coordinates of the first shipping plant). Furthermore, the driving time of the transport vehicle is defined as the driving time from the shipping plant from which the vehicle is shipped, and is managed in association with at least the time of departure from the shipping plant.

[0023] In this embodiment, each vehicle is equipped with an on-board device that collects information indicating the driving state (driving data), and outputs the driving data to a storage device 90 via a network 40. The on-board device is equipped with, for example, a GPS (Global Positioning System) function and collects information on the vehicle's location and driving time. The on-board device may be, for example, a car navigation system, but is not limited to a specific device as long as it is capable of obtaining information on the vehicle's location and driving time. As another example, the on-board device may be a driving recorder such as a digital tachograph. As another example, the on-board device may be a smartphone that is brought into the vehicle by the driver and functions as a car navigation system using an application.

[0024] The components of the ready-mixed concrete ordering support device 10 will be described in detail below. The communication unit 11 is configured to include one or more communication modules connected to the network 40. The communication unit 11 may include a communication module compatible with mobile communication standards such as 4G (4th Generation) and 5G (5th Generation). The communication unit 11 may include a communication module compatible with wired or wireless LAN standards, for example.

[0025] The storage unit 12 is one or more memories. The memory may be, for example, a semiconductor memory, a magnetic memory, an optical memory, or the like, but is not limited to these, and may be any memory. The storage unit 12 is built into the ready-mixed concrete ordering support device 10, for example, but may also be configured to be accessed from outside by the ready-mixed concrete ordering support device 10 via any interface.

[0026] The storage unit 12 stores various data used in various calculations performed by the control unit 13. The storage unit 12 may also store results and intermediate data of various calculations performed by the control unit 13.

[0027] In this embodiment, the storage unit 12 may temporarily store various information obtained from the database of the storage device 90 on the cloud via the communication unit 11.

[0028] The control unit 13 is one or more processors. The processor may be, for example, a general-purpose processor or a dedicated processor specialized for a specific process, but is not limited to these and may be any processor. The control unit 13 controls the overall operation of the ready-mix concrete ordering support device 10.

[0029] Here, the ready-mixed concrete ordering support device 10 may have the following software configuration: One or more programs used to control the operation of the ready-mixed concrete ordering support device 10 are stored in the memory unit 12. When the program stored in the memory unit 12 is read by the processor of the control unit 13, it causes the control unit 13 to function as an acquisition unit 131, a generation unit 132, and an output unit 133.

[0030] The acquisition unit 131 acquires past driving performance data including the location and driving time of a transport vehicle that transports ready-mixed concrete from a shipping plant, and map information. The acquisition unit 131 may further acquire information required for calculation in the generation unit 132 (for example, the location of the shipping plant, the location of the base of the rescue vehicle, etc.) via the network 40. In this case, the location of the shipping plant, the location of the base of the rescue vehicle, etc. may be stored in advance in the storage device 90.

[0031] The generation unit 132 generates an isotime line map from the shipping factory based on the map information and driving performance data acquired by the acquisition unit 131. The isotime line map represents the required time from a specific point (the shipping factory in this embodiment) on a map, and is generated by connecting points at the same time distance (i.e., required time) with isotime lines. Figure 4 shows an example of the isotime line map generated by the generation unit 132 and shown to the orderer.

[0032] Here, because vehicles transporting ready-mixed concrete are large, specialized vehicles, the roads they can travel on are limited (see Figure 2). Therefore, accurate transportation times cannot be calculated using calculation methods designed for general vehicles, and conventional technologies have made it difficult to accurately display required travel times on a map. Furthermore, conventional technologies sometimes roughly display required travel times using regional divisions (e.g., municipal divisions) on a map, further reducing the accuracy of required travel times. In this embodiment, the generation unit 132 uses past travel performance data to match the map information, thereby accurately calculating past travel times using only drivable roads and generating an isotime diagram. By referencing a highly accurate isotime diagram of transport times, purchasers can confirm in advance (before placing an order) whether delivery is possible. In other words, the ready-mixed concrete ordering support device 10 can provide purchasers with accurate information by generating such an isotime diagram using the generation unit 132.

[0033] The generation unit 132 can generate an isochrone diagram by mapping the vehicle's position at the same travel time determined from the travel history data onto the map information. However, since vehicle positions may vary depending on road conditions (e.g., whether there is traffic congestion), the travel history data may be divided into multiple time periods, and an isochrone diagram may be generated for each of the multiple time periods. That is, the generation unit 132 may divide the travel time of the transport vehicle into multiple time periods and generate an isochrone diagram for each of the multiple time periods. By dividing into multiple time periods, more accurate information can be provided to the orderer, taking into account the traffic conditions for each time period. The multiple time periods may be, for example, morning, afternoon, or night, or may be further divided (e.g., every three hours, such as 6:00 to 9:00). Furthermore, instead of or in addition to multiple time periods, divisions based on seasons, etc. may be used.

[0034] Furthermore, the generation unit 132 may set a transportable area in the isochrone diagram to an area that is included within the allowable transport time from the shipping factory. As described above, the allowable transport time for ready-mixed concrete is set to, for example, 90 minutes. Therefore, the generation unit 132 may set a transportable area based on whether it is included in the allowable transport time (or a time shorter than the allowable transport time). For example, the transportable area may be colored so that it is visually distinguishable from other areas. By generating such an isochrone diagram, the purchaser can easily confirm whether transport is possible or not based on the isochrone diagram when placing an order.

[0035] Here, the generation unit 132 can generate an isotime diagram that reflects the actual situation by performing statistical processing on variations in vehicle positions due to road conditions (e.g., whether or not there is traffic congestion). For example, FIG. 7 is a diagram illustrating the frequency of the travel time required for a vehicle to reach a specific location in driving history data. A vehicle that departs from a shipping factory often arrives by a certain time (the travel time indicated by the dashed line on the horizontal axis in FIG. 7 ), but occasionally exceeds the required time. However, if the travel time is adjusted to reflect the rarely occurring time exceedance, an isotime diagram that does not reflect the actual situation will be generated. Therefore, the generation unit 132 sets a threshold value less than 100% (e.g., 95%). Then, the generation unit 132 sets a transportable area in the isotime diagram to an area that is included within the allowable transportation time from the shipping factory and where the probability of arrival based on the driving history data is equal to or greater than the threshold. By generating such an isotime diagram, the actual situation is appropriately reflected, thereby improving the reliability of the determination of whether transportation is possible or not based on the isotime diagram.

[0036] The generation unit 132 may also generate the isochrone diagram taking into consideration the circumstances of the order-receiving party (shipping plant). If a ready-mixed concrete transport vehicle is unable to move due to, for example, a breakdown, the hardening of the ready-mixed concrete may render the onboard equipment unusable, necessitating the replacement of the equipment. Therefore, it is preferable for the shipping plant to set a transportable area within a predetermined time (e.g., within 30 minutes) that a rescue vehicle can reach in the event of a breakdown. Rescue includes, for example, towing the broken-down transport vehicle and emergency repairs. The generation unit 132 may set a rescueable area within a predetermined time range from the rescue vehicle's base in the isochrone diagram, and may set a transportable area within an allowable transport time range from the shipping plant that overlaps with the rescueable area. Figure 5 shows an isochrone diagram with the rescueable area displayed overlaid. As shown in Figure 5, the transportable area may be set within the allowable transport time range and within the rescueable area. By generating such an isochrone diagram, it is possible to provide useful information to the purchaser, taking into consideration the risk of breakdown of the transport vehicle at the shipping factory.

[0037] Here, although it is generally difficult to transport goods to the delivery destination outside the salvageable area, the shipping factory may accept the order after setting a surcharge. The generation unit 132 may set a surcharge area in the isotime diagram, in which a surcharge will be incurred, in an area that is included within the allowable transportation time from the shipping factory and does not overlap with the salvageable area. From the perspective of cost management, purchasers may wish to confirm whether or not a surcharge will be incurred before placing an order. By generating such an isotime diagram, purchasers can confirm whether or not a surcharge will be incurred based on the isotime diagram when placing an order. In addition, purchasers can know the reason for the surcharge (outside the salvageable area) and can place an order only after understanding the reason.

[0038] Furthermore, when the isochrone diagram covers a wide area, it may include multiple shipping plants. When there are multiple shipping plants and the areas within the allowable transportation time from the shipping plants overlap, the generation unit 132 may generate the isochrone diagram by prioritizing the shipping plant with the shortest arrival time for the overlapping areas. FIG. 6 illustrates an example of an isochrone diagram when multiple shipping plants (a first shipping plant and a second shipping plant) are included. In the example of FIG. 6, for the area where the transportation area from the first shipping plant (the first transportation area) and the transportation area from the second shipping plant (the second transportation area) overlap, the second transportation area with the shortest arrival time for the transportation vehicle is prioritized. By generating such an isochrone diagram, it is possible to provide the purchaser with more accurate information that takes into account shipments from multiple shipping plants.

[0039] The output unit 133 outputs the isochrone diagram generated by the generation unit 132 so that it can be used by the purchaser of ready-mixed concrete. The output isochrone diagram is shown on the display unit of the terminal device 50. The purchaser can order ready-mixed concrete based on the information included in the isochrone diagram. Here, the isochrone diagram may be output so as to become part of an ordering screen displayed on the display unit of the terminal device 50. The ordering screen is a screen for the purchaser to order ready-mixed concrete, and may be configured to allow the purchaser to input the quantity, delivery destination, delivery date and time, etc.

[0040] The ready-mixed concrete ordering support device 10 according to this embodiment may execute the following process of the ready-mixed concrete ordering support method: Fig. 3 is an example of a flowchart showing the process of the ready-mixed concrete ordering support method according to this embodiment.

[0041] First, the acquisition unit 131 acquires past travel record data including the location and travel time of the transport vehicle, and map information (step S1).

[0042] The generating unit 132 generates an iso-time line map from the shipping factory based on the map information and driving performance data acquired by the acquiring unit 131 (step S2).

[0043] The generation unit 132 sets the transportable area in the isochrone diagram to an area included in the range of the transportable time from the shipping factory (step S3). As described above, the transportable area may be set in consideration of at least one of an area where the reachability probability is equal to or greater than a threshold, a rescueable area, and a premium charge area.

[0044] The output unit 133 outputs the isochrone diagram generated by the generation unit 132 so that it can be used by the orderer of ready-mixed concrete (step S4).

[0045] As described above, the ready-mixed concrete ordering support device 10, program, and ready-mixed concrete ordering support method according to this embodiment generate an isochrone diagram using the above configuration, and therefore can provide accurate information to the purchaser.

[0046] Although the embodiments of the present disclosure have been described based on the drawings and examples, it should be noted that a person skilled in the art would easily be able to make various modifications or alterations based on the present disclosure. Therefore, it should be noted that these modifications or alterations are included in the scope of the present disclosure.
