JP 2002-183264 A

  However, the delivery support system represented by Patent Document 1 has a problem in that the delivery date of the package is determined regardless of the convenience of the customer, which does not lead to an improvement in service to the customer. Specifically, in many cases, it is convenient for the customer to deliver on the designated delivery date, but there is a problem that there is no merit to accept the change of the delivery date without considering it.

  For this reason, when determining a delivery plan for delivering a package, how to improve the service to the customer is an extremely important problem in effectively using the delivery support system.

  The present invention has been made to solve the above-described problems caused by the prior art, and provides a delivery plan creation program and a delivery plan creation method capable of creating a delivery plan while improving services for customers. With the goal.

  In order to solve the above-described problems and achieve the object, the present invention is a delivery plan creation program for creating a delivery plan for delivering a package, and a delivery timing determination procedure for determining a delivery timing for delivering each package; A delivery charge calculation procedure for calculating a delivery charge for each package based on a delivery time for delivering each package determined by the delivery time determination procedure is executed by a computer.

  The present invention further includes a delivery fee information storage procedure for storing information relating to a delivery fee corresponding to a delivery time for delivering the package, wherein the delivery fee calculation procedure is a delivery stored by the delivery fee information storage procedure. A delivery fee for each package is calculated by referring to information related to the fee.

  According to the present invention, after the delivery time determination procedure determines a first delivery time for delivering a package at a designated time, a second delivery time for delivering a package for which the delivery time is not designated is determined. It is characterized by that.

  Further, according to the present invention, in the delivery time determination procedure, when determining the second delivery time, the total delivery amount of the package at each delivery time is limited to a predetermined ratio or less of the deliverable amount of the package at the delivery time. The delivery time of each package is determined.

  The present invention also relates to a delivery plan creation method for creating a delivery plan for delivering a package, a delivery time determining step for determining a delivery time for delivering each package, and each package determined by the delivery time determining step. A delivery charge calculating step of calculating a delivery charge for each package based on the delivery time for delivering the package.

  According to the present invention, the delivery time for delivering each package is determined, and the delivery charge for each package is calculated based on the determined delivery time for delivering each package. However, the delivery plan can be created.

  In addition, according to the present invention, information related to the delivery fee corresponding to the delivery time for delivering the package is stored, and the delivery fee for each package is calculated by referring to the stored information related to the delivery fee. Therefore, it is possible to efficiently calculate the delivery fee and to produce a delivery plan while improving the service for the customer.

  Further, according to the present invention, after determining the first delivery time for delivering the package at the designated time, the second delivery time for delivering the undesignated package is decided. It is possible to reliably set the delivery time of the package with the designated delivery time and to create a delivery plan while improving the service to the customer.

  Further, according to the present invention, when determining the second delivery time, the total delivery amount of the package at each delivery time is limited to a predetermined ratio or less of the deliverable amount of the package at the delivery time, and each package is delivered. Since it was decided to decide the timing, even if an order with a delivery date is accepted after the delivery time has been decided, a delivery date can be assigned to the order and a delivery plan can be created while improving customer service. There is an effect that can be done.

  Exemplary embodiments of a delivery plan creation program and a delivery plan creation method according to the present invention will be described below in detail with reference to the accompanying drawings.

  First, the concept of the delivery plan creation system according to the present embodiment will be described. FIG. 1 is a conceptual diagram illustrating the concept of a delivery plan creation system according to the present embodiment. As shown in FIG. 1, in this delivery plan creation system, order data received from a customer is acquired. The order data includes information on whether or not a delivery date has been designated by the customer.

  This delivery plan creation system receives received order data, weather data, road construction data, expressway toll data, map data, which is a constraint condition when creating a delivery plan when no delivery date is specified. In addition, cost simulation is performed in consideration of inventory data, production plan data, vehicle data, delivery destination data, delivery base data, and the like, and the delivery date of each package is determined so that the delivery cost is minimized.

  Here, the weather data is data related to the weather during the period for which the delivery schedule is created, the road construction data is data on road conditions such as road closure due to road construction, and the expressway toll data is the expressway usage fee. Map data is data such as position information, distance information, road speed limits, and the like of roads and buildings.

  In addition, the inventory data is data such as the inventory status of the package to be delivered, the production plan data is data such as the production time and the production volume of the package to be delivered, and the vehicle data is the availability information of the vehicle on which the package is loaded. And the maximum load capacity of each vehicle, the delivery destination data is data such as the address of the delivery destination that delivers the package, and the delivery base data is data such as the address of the delivery base that delivers the package. .

  Thereafter, the delivery plan creation system refers to the delivery fee data and determines the delivery fee for each package based on the decided delivery date. Here, the delivery fee data is data storing a delivery fee for each weight of the package, a discount condition for the delivery fee, and the like.

  Specifically, this delivery plan creation system applies a higher discount rate to the delivery fee and determines the delivery fee for each package as the interval between the order date and the delivery date increases. When a delivery date is designated by the customer, the delivery date is determined on the designated date. Then, the information of the determined delivery date and delivery fee is output and notified to the customer.

  FIG. 2 is a diagram showing an example of a delivery plan creation process performed by the delivery plan creation system shown in FIG. FIG. 2 shows a case where a delivery order of 3 tons and 100 packages is received on September 10, and the result of the cost simulation is determined to deliver the package received on September 13. Yes.

  In this example, it is determined in advance that 10% of the delivery fee will be discounted if delivered within 3 days from the order, and 20% of the delivery fee will be discounted if delivered within 3 to 7 days after the order. It has been. Accordingly, since September 13 corresponds to the third day from the order date, the delivery management system calculates a delivery fee discounted by 10% and outputs the result.

  In this way, when the delivery date from the customer is not specified, the delivery date is determined by cost simulation, and the delivery fee is discounted according to the interval between the determined delivery date and the order date, so the service to the customer is improved. A delivery plan can be created.

  Next, a functional configuration of the delivery plan creation system according to the present embodiment will be described. FIG. 3 is a functional block diagram illustrating a functional configuration of the delivery plan creation system according to the present embodiment. This delivery plan creation system is a system for creating a delivery plan for delivering a package. In addition to simply determining a delivery date for delivering each package and creating a delivery plan, the delivery date for each package is determined. Based on this, a process for calculating a delivery fee for each package is performed.

  The delivery plan creation system includes an input unit 30, a display unit 31, a storage unit 32, and a control unit 33. The input unit 30 is an input device such as a keyboard or a mouse, and the display unit 31 is a display device such as a display. The storage unit 32 is a storage device such as a hard disk device, and the storage unit 32 stores delivery fee data 32a, order data 32b, and constraint data 32c.

  The delivery fee data 32a is data that stores information related to the delivery fee of the package, conditions for discounting the delivery fee, and the like. FIG. 4 is a diagram showing an example of the delivery fee data 32a shown in FIG. As shown in FIG. 4, the delivery fee data 32a includes items of delivery fee information ID, customer ID, delivery fee information, discount condition 1, and discount condition 2.

  The delivery fee information ID is an ID number for identifying the delivery fee information. The customer ID is an ID number that identifies a customer to which the delivery fee is applied. The delivery fee information is information on the unit weight of the package to be delivered and the delivery fee per piece.

  Discount condition 1 and discount condition 2 set conditions for discounting delivery charges. For example, discount condition 1 is a condition that “If the delivery date is within A days from the order date, a discount of N% is performed”, and discount condition 2 is “the delivery date is within A + 1 days or more and B days from the order date. In this case, the condition is “M% (M> N) discount”.

  The order data 32b is data that stores information related to delivery ordered from a customer, and is data that stores information on a package to be delivered, information on designation / non-designation of a delivery date, and the like. FIG. 5 is a diagram illustrating an example of the order data 32b illustrated in FIG. As shown in FIG. 5, the order data 32b includes an order ID, a customer ID, a data type, a delivery date designation flag, an order date, a delivery designation date / delivery deadline date, package information, a dispatch flag, a delivery date, and a delivery fee. Has each item.

  The order ID is an ID number that identifies an order received from a customer. The customer ID is an ID number that identifies the customer who has received the order. The data type is a type indicating whether the received order is new (new data), or whether the delivery date has been carried forward (remaining data) in the processing of the previous day. The delivery date designation flag is a flag that indicates whether designation of a date for delivering a package from a customer has been accepted, and is a flag that indicates either a delivery date designation or no delivery date designation.

  The order date is the date when the order is accepted. The designated delivery date / delivery deadline is the date of the designated delivery date when the delivery designation flag is in the designated delivery date state, and the delivery deadline when the delivery designated flag is in the no delivery date designated state. This is the date of the set delivery deadline.

  The package information is information such as the name, number, weight, package, and delivery destination of the package to be delivered. The dispatch flag is a flag that indicates whether the delivery date of the package has been determined and the vehicle has been allocated for the package, and is a flag that indicates either a completed or incomplete state. The delivery date is a delivery date of the package determined as a result of the cost simulation, and the delivery fee is a delivery fee applied to the package.

  Returning to the description of FIG. 3, the constraint data 32c is data of various constraints input when performing the cost simulation. The weather data, road construction data, highway toll data, and map shown in FIG. Data such as data, inventory data, production plan data, vehicle data, delivery destination data, and delivery base data.

  The control unit 33 is a control unit that controls the entire delivery plan creation system, and includes a data reception unit 33a, a delivery time determination unit 33b, a delivery fee calculation unit 33c, and an information output unit 33d.

  The data receiving unit 33a is a receiving unit that receives the delivery fee data 32a, the order data 32b, and the constraint condition data 32c input to the input unit 30 and stores them in the storage unit 32. In addition, the data receiving unit 33a receives a vehicle allocation condition when the vehicle is allocated to each package input to the input unit 30, and performs a process of updating the stored data 32a to 32c.

  For example, the data accepting unit 33a accepts data on the number of vehicles that can be dispatched as a dispatching condition, and updates setting data (corresponding to the vehicle data in FIG. 1) stored in the constraint condition data 32c described later. The number of vehicles may be the number of vehicles that have been directly input by the user, or the data receiving unit 33a that has received an automatic update command from the user may increase the number of vehicles by one daily. . As another dispatch condition, it is also possible to directly accept the specification of the delivery date of the package from the user and determine the delivery date.

  The delivery time determination unit 33b executes the cost simulation shown in FIG. 1 on the basis of the delivery charge data 32a, the order data 32b, and the constraint data 32c stored in the storage unit 32, so that each package ordered from the customer is received. It is a determination part which determines a delivery time.

  Specifically, when determining the delivery time of each package, the delivery time determining unit 33b executes the dispatch for the package for which the delivery date is designated as the primary dispatch process. Thereafter, for a package for which a delivery date is not designated, the dispatching under the condition of discount condition 1 shown in FIG. 4 is executed as a secondary dispatching process. That is, a search is made for a deliverable date with the lowest delivery cost within A days from the order date, and a vehicle is delivered to a package for which no delivery date is specified.

  Furthermore, the delivery time determination unit 33b executes the allocation in the condition of the discount condition 2 shown in FIG. 4 as the tertiary allocation process for the packages that could not be allocated even in the secondary allocation process. That is, a search is made for a deliverable date with the lowest delivery cost within A + 1 days or more and B days from the order date, and dispatch is performed for a package for which no delivery date is specified.

  Here, the delivery time determination unit 33b determines whether or not there is a day when the total delivery amount of the baggage of a day exceeds a predetermined percentage of the deliverable amount of the day after the delivery date is determined by the tertiary delivery process. If a predetermined ratio is exceeded, a condition for restricting delivery of the excess baggage from the next day is added, and the third dispatch process is executed again. This is because there is a possibility that an order for which a delivery date is specified within the period of the discount condition 2 may be received from the customer, and the delivery capability is secured so that the order can be handled.

  Further, the delivery time determination unit 33b determines whether or not the order data 32b for which the dispatch process has not been completed is likely to have passed the delivery deadline date, and warns the user if there is such a possibility. . For example, the delivery time determination unit 33b determines that there is a possibility that the delivery deadline date will be exceeded if it is three days before the delivery deadline date.

  The delivery fee calculation unit 33c is a calculation unit that calculates the delivery fee of each package based on the delivery date of each package determined by the delivery time determination unit 33b. Specifically, the delivery fee calculation unit 33c calculates a non-discount fee when delivering a package on the delivery date designated by the customer, but the delivery date is not designated by the customer and is from the order date. When delivering a package after the period has elapsed, a delivery fee discounted based on discount conditions 1 and 2 shown in FIG. 4 is calculated.

  The information output unit 33d is an output unit that outputs information on the delivery date of the package determined by the delivery time determination unit 33b, information on the delivery fee calculated by the delivery fee calculation unit 33c, and the like to the display unit 31 and the like.

  Next, a processing procedure of a delivery plan creation process performed by the delivery plan creation system according to the present embodiment will be described. FIGS. 6A and 6B are flowcharts (1) and (2) illustrating the processing procedure of the delivery plan creation process performed by the delivery plan creation system according to the present embodiment. Here, it is assumed that this delivery plan creation process is performed every business day.

  As shown in FIG. 6A, first, the data receiving unit 33a of the delivery plan creation system receives the new order data 32b (step S601), and then the remaining order data that has not been processed yet by the previous day. 32b is acquired (step S602).

  Then, the delivery time determination unit 33b acquires the delivery fee data 32a and the constraint condition data 32c (step S603), and extracts the order data 32b with the delivery date specified (step S604).

  Thereafter, the delivery time determination unit 33b executes a primary dispatch process, and performs a dispatch process for a package with a specified delivery date (step S605). Then, the delivery fee calculation unit 33c performs a process of calculating the delivery fee of the package that has been dispatched by the primary dispatch process (step S606). However, since the package has a delivery date specified here, the delivery charge is not discounted. This delivery fee calculation process will be described in detail with reference to FIG.

  Subsequently, the delivery time determination unit 33b performs a secondary delivery process by executing a cost simulation, and performs a process of determining a delivery date of the package during the period of the discount condition 1 shown in FIG. 4 (step S607).

  Then, the delivery time determination unit 33b checks whether or not the dispatching process for all the order data 32b is completed (step S608), and when the dispatching process for all the order data 32b is completed (Yes in step S608), The dispatch flag of the order data 32b is set to “completed” (step S609).

  Thereafter, the delivery fee calculation unit 33c performs a delivery fee calculation process described in FIG. 7 (step S610), and the information output unit 33d outputs information on the determined delivery date and delivery fee (step S611). The delivery plan creation process ends.

  In step S608, when the dispatch process for all the order data 32b is not completed (No in step S608), as shown in FIG. 6-2, the delivery time determination unit 33b has not completed the dispatch process. The dispatch flag of the order data 32b is set to “incomplete” (step S612).

  Then, the data reception unit 33a receives an input of a vehicle allocation condition (step S613), and the delivery time determination unit 33b re-executes the secondary vehicle allocation process based on the received vehicle allocation condition (step S614).

  Thereafter, the delivery time determination unit 33b checks whether or not the dispatching process for all the order data 32b is completed (step S615). If the dispatching process for all the order data 32b is completed (Yes in step S615), The process proceeds to step S609 and the subsequent processing is continued.

  When the dispatch process for all the order data 32b is not completed (No in step S615), the delivery time determination unit 33b executes the tertiary dispatch process by executing the cost simulation, and the discount shown in FIG. Processing for determining the delivery date of the package during the period of condition 2 is performed (step S616).

  Then, the delivery time determination unit 33b checks whether there is a day when the total delivery amount of the day exceeds a predetermined rate with respect to the deliverable amount of the day based on the result of the tertiary vehicle allocation process (step S617). If there is a date that exceeds (step S617, Yes), a condition for limiting the delivery date to the next day or later is set (step S622), and the process proceeds to step S616 to continue the subsequent processing.

  If there is no day when the total delivery amount of the day exceeds a predetermined ratio with respect to the deliverable amount of the day (No in step S617), it is checked whether or not the dispatching process for all the order data 32b is completed (step S618). ) When the dispatch process for all the order data 32b is completed (step S618, Yes), the process proceeds to step S609 and the subsequent processes are continued.

  When the dispatch process for all the order data 323b is not completed (step S618, No), the delivery time determination unit 33b sets the data type of the order data 32b for which the dispatch process is not completed to “remaining data”. (Step S619). Thereafter, the delivery time determination unit 33b checks whether there is a possibility that the delivery order date 32b for which the dispatch process has not been completed has passed the delivery deadline date (step S620).

  If there is no possibility that the delivery deadline date will elapse (step S620, No), the delivery plan creation process is terminated as it is. If there is a possibility that the delivery deadline date has passed (step S620, Yes), the information output unit 324d outputs a warning message (step S621), and ends this delivery plan creation process.

  Next, the processing procedure of the delivery charge calculation process shown in FIG. FIG. 7 is a flowchart showing a processing procedure of the delivery charge calculation process shown in FIG. As shown in FIG. 7, first, the delivery fee calculation unit 33c checks whether or not there is order data 32b for which the primary dispatch has been completed (step S701).

  If there is order data 32b for which primary dispatch has been completed (step S701, Yes), the delivery fee calculation unit 33c calculates the delivery fee without discount, stores the calculated delivery fee (step S704), and step The process proceeds to S702. If there is no order data 32b for which the primary delivery has been completed (No in step S701), the delivery fee calculation unit 33c checks whether there is the order data 32b for which the secondary delivery has been completed (step S702).

  If there is order data 32b for which secondary dispatch has been completed (step S702, Yes), the delivery fee calculation unit 33c calculates a delivery fee with a discount of A%, and stores the calculated delivery fee (step S705). ), The process proceeds to step S703. If there is no order data 32b for which the secondary delivery has been completed (No in step S702), the delivery fee calculating unit 33c checks whether there is the order data 32b for which the third delivery has been completed (step S703).

  If there is order data 32b for which the third delivery has been completed (step S703, Yes), the delivery fee calculation unit 33c calculates a discount delivery fee of B% and stores the calculated delivery fee (step S706). The delivery fee calculation process is terminated as it is. If there is no order data 32b for which the third delivery has been completed (step S702, No), the delivery fee calculation unit 33c ends this delivery fee calculation process.

  Incidentally, the delivery plan creation system and delivery plan creation method described in the above embodiments can be realized by executing a program prepared in advance on a computer system such as a personal computer or a workstation.
