Description

  The present invention relates to an article delivery system.

  In an article delivery system that delivers a predetermined article to a predetermined place, a delivery vehicle loads the article stocked in a warehouse and delivers the article to a predetermined place. In general, in a system that loads packages from a single warehouse called a single depot and transports them to multiple delivery destinations, the transport route and time are set to be the shortest. A system for setting a vehicle allocation is known.

  Such a single depot system delivers packages via a specific single warehouse at all destinations. Therefore, depending on the location of the delivery destination, the delivery vehicle moves to the warehouse located in the opposite direction to the delivery destination, and after the delivery article is loaded on the vehicle, it moves to the delivery destination located in the opposite direction from the direction where it came again. As a result, the delivery time becomes longer, which increases the delivery cost.

In order to suppress an increase in delivery cost due to such a single depot, Patent Document 1 discloses a delivery plan system in a plurality of warehouses called a multi-depot. In the delivery planning system disclosed in Patent Document 1, it is shown that a route with the shortest delivery route is selected from a plurality of storage warehouses and a vehicle dispatch plan on the day of delivery is created.
JP 2004-59231 A

  According to the delivery planning system disclosed in Patent Document 1, the delivery time can be further shortened as compared with the delivery system of the conventional single depot.

  On the other hand, there is a case where a shortening of the delivery time is further requested due to a request from the delivery destination. For example, repair parts for automobiles are examples. At the request of a customer, when a failed car is received at a repair shop and parts need to be replaced, and there is no parts inventory at the repair shop, a spare parts can be ordered immediately from a parts sales company and obtained as quickly as possible. There is a need to. This is because if it takes time to obtain parts, the customer cannot use the car during that time.

  Therefore, when priority is given to shortening the delivery time, such as repair parts, by increasing the number of warehouses in the multi-depot, it is possible to deliver to delivery destinations distributed in various locations in a relatively short time. .

  On the other hand, increasing the number of warehouses naturally increases the cost of maintenance of the warehouses, which is a factor in reducing delivery costs. In addition, the number of parts for vehicle repair parts is enormous, and if each inventory is maintained in each warehouse, the storage cost including the maintenance cost of the warehouse itself becomes enormous. Therefore, although parts that are used frequently are stocked in each warehouse, parts that are used infrequently are not stocked by each warehouse, but some warehouses stock it.

  Furthermore, in terms of reducing storage costs, it is effective to reduce the number of parts in stock. However, depending on the stock quantity, a specific part in the delivery time zone may be out of stock. In this case, the number of warehouses is reduced for the specific part, and the effectiveness of the multi-depot is reduced. In other words, when a part order is entered after a stockout occurs, a warehouse that is advantageous in terms of delivery time cannot be selected, and only a warehouse that has a longer delivery time can be selected.

  The present invention provides a delivery system that does not reduce the advantage of multi-depots in a delivery system that supports multi-depots by considering the number of stocks in each warehouse and suppressing out-of-stocks in each warehouse.

  In order to solve the above-described problem, the invention according to claim 1 of the present invention moves a delivery means such as a vehicle located at an arbitrary location to a storage location for a plurality of articles set at different locations, and stores the storage location. In an article delivery system for carrying out a particular article from the delivery and delivering the article to an orderer located at an arbitrary place by delivery means, ordering part number information issued from an orderer located at an arbitrary place, and the orderer Order information storage and acquisition means for storing the position information, and inventory information storage means for storing inventory information for each product number in the plurality of storage locations, the inventory information and the ordered product number information are collated, and the ordering A specific inventory storage location extracting means for extracting a storage location for stocking an article having a product number as a specified inventory storage location, and when the specified inventory storage location is single, the delivery means extracts the special location. Route search means for searching the shortest route among the routes from the stock storage location to the ordering source as the shortest route, the positional information of the specific stock storage location, the shortest route, and the ordering Delivery plan display means for displaying delivery plan information composed of product number information and position information of the ordering source, and when there are a plurality of specific stock storage locations, the route search means causes the delivery means to A route search is made for each specified stock storage location using the shortest route among the routes from the specified stock storage location to the ordering source as the shortest route, and the shortest required time among the shortest route times is the shortest. Specified inventory that has a larger number of items in stock with the order item number when the required time is 2 or more when the required time is within the predetermined time from the shortest required time. Route selection means for selecting a route passing through a pipe location as a specific shortest route, the position information of the specific stock storage location selected by the route selection means, the specific shortest route, the order part number information, and An article delivery system, characterized in that delivery plan information comprising position information of the ordering source is displayed on the delivery plan display means.

  In the shipping system according to the present invention, it is possible to suppress the stock-out at each warehouse in the multi-depot, and to maximize the effect of shortening the shipping time by the multi-depot.

  Hereinafter, a delivery system according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a delivery system of the present invention, and FIGS. 2 and 3 are diagrams showing delivery routes by the delivery system of the present invention.

  The delivery system 101 of the present invention moves a delivery means B such as a vehicle located at an arbitrary place to storage locations C1 to Cn of a plurality of articles set at different locations, and carries out a specific article from the storage location C. Then, the delivery means B delivers the article to the orderer A located at an arbitrary location.

  The delivery system 101 of the present invention includes an ordering part number information issued from an orderer located at an arbitrary place (corresponding to the ordering party A), ordering information storage means 102 for storing the ordering party position information, and a plurality of storages. It has inventory information storage means 103 that stores inventory information for each product number at the location.

  The order information storage means 102 is stored on the server by inputting the corresponding product number, the location information of the orderer, and the orderer name from a home page published on the Web server from an information terminal such as a computer or a mobile phone. be able to. Alternatively, the person in charge of the order receiving the telephone / FAX communication from the orderer may input the information into the order receiving computer and store it in the order receiving server. Further, as the stock information storage means 103, information storage means such as a server may be used. When inventory information is managed by a server, it is advantageous in that the inventory information on the server can be updated to the latest by connecting the inventory information management terminal at each storage location and the server. In addition, instead of a specific product number, for example, information that can identify a desired component C, such as “a component C suitable for a product B manufactured by Company A”, may be used as the article product number information.

  Then, the specific stock storage location extraction means 104 collates the inventory information with the ordered product number information, and extracts the storage location that stocks the article having the ordered product number as the specific stock storage location. The specific stock storage location extraction means 104 only needs to perform two types of information collation processing on the computer, and the function is in either one of the server storing the stock information and the server storing the order source information. Just run it.

  In the present invention, when there is a single specific stock storage location, for example, when the storage location Ck is the only specific stock storage location in FIG. 2, the delivery means B leads to the orderer A via this storage location Ck. Route search means 105 is provided for searching for the shortest route among the routes as the shortest route.

  As the route search means 105, the shortest route search means mounted in the conventional car navigation system can be used, and it depends on the location information of the delivery means B specified by GPS, etc., the storage location Ck, and the location information of the orderer. In addition, it is possible to obtain three points of position information necessary for route search: a departure point, a transit point, and an arrival point. Similarly to the car navigation system, information such as traffic congestion and traffic regulation may be acquired from the VICS, and the route with the shortest required time may be searched as a shortest route after taking the information into consideration. This route search means 105 has distance / required time information of each road, and can be constituted by a route search server that executes a route search program.

  Also, if a toll road is included in the searched shortest route, the toll will be evaluated as part of the required time, taking into account whether the toll is commensurate with the time reduction, and added to the actual required time. May be.

  After that, the shipping plan display means 106 uses the location information of the specific stock storage location, the orderer information including the order item number and the order source location information, and the shortest path information to reach the order source from the delivery means via the specific stock storage location. Display delivery plan information consisting of As a display method, a display such as an LCD is generally used, but an audio display can be used together.

  Then, the driver of the delivery means B such as a truck may deliver the article to the orderer A through a predetermined route according to the delivery plan information displayed by the dispatch plan display means 106.

  Note that the configuration of the present invention can realize its functions on computers and servers that are network-connected to each other. However, since the delivery means B is located at an arbitrary place, the shipping plan display means 106 should always be installed in the delivery means B where the driver can confirm the display.

  Note that other order receiving servers, inventory information storage servers, and route search servers can perform their functions as long as they are connected to the network, and therefore do not need to be fixed at a specific location.

  Next, in the present invention, when there are a plurality of specific stock storage locations, the route search unit 105 causes the route search unit 105 to select the route with the shortest required time among the routes from the delivery unit B via the specific stock storage location to the orderer. A route search is performed for each specified stock storage location as a route.

  This will be described with reference to FIG. Among the storage locations C1, C2, C4, C5, Ck, and Cn, the storage locations C1, C3, C5, and Ck indicated by black circles are assumed to be specific stock storage locations that stock items ordered by the ordering source. In the present invention, the route search unit 105 is used to search, for each storage location, the route with the shortest required time among the routes from the delivery unit B through the storage location to the orderer A as the shortest route.

  For example, the required time on the shortest route via Ck is Tk, the required time on the shortest route via C1 is T1, the required time on the shortest route via C3 is T3, and the required time on the shortest route via C5 If the time is T5, and Tk <T3 <T5 <T1, for example, the shortest required time is the shortest required time Tk, and the required time is within the predetermined time t (t> 0) from the shortest required time Tk. Find the shortest path. The predetermined time t is set to a time that is acceptable to the orderer when delivering the article.

  For example, if Tk <(Tk + t) <T3 <T5 <T1, and the required time is within the predetermined time t from the shortest required time Tk, the single Tk is passed to the delivery plan display means 106 via Ck. In this case, a delivery plan including the shortest path information, ordering part number information, and ordering source position information is displayed.

  Further, when Tk <T3 <(Tk + t) <T5 <T1 and the required time is within the predetermined time t from the shortest required time Tk, a plurality of Tk and T3, the storage location Ck and the storage location C3 The delivery plan including this information is displayed on the delivery plan display means 106, with the shortest route that passes through one of the ordered items in stock as the specified shortest route. If the parts inventory is the same, the route having the shortest required time and passing through Ck is set as the specified shortest route, and the delivery plan including the information is displayed on the delivery plan display means 106. In the same way, when T5 or T1 enters Tk to (Tk + t), the number of stocks at each storage location is compared, and the shortest route via storage location C having the maximum stock count is selected as the specific shortest route. do it.

  Such route selection is performed using the route selection unit 107 from the inventory information and the route obtained by the inventory information storage unit 103 and the route search unit 105, respectively. Specifically, the route selection means 107 is configured by a programmed computer. Of course, the program may be installed in a computer that functions as an inventory information storage server or a route search server.

  According to the delivery system of the present invention as described above, since it corresponds to multi-depots and it is avoided that the stock of each storage location becomes zero, the time required for delivery is always shortened without impairing the advantages of multi-depots. be able to.

  The present invention can be applied to delivery of various articles. In particular, delivery of items that require reduced delivery time, such as battery and other automotive repair parts, and repair parts for various devices, and that require a large variety of stocks and that the number of stocks for each product type is limited. It is suitable for.
