Description

Delivery plan preparation system and delivery plan preparation method

technical field

The invention relates to a production system and a production method of a distribution plan.

Background technique

For a long time, when multiple buyers obtain goods of a considerable size from one or more suppliers who manufacture the goods, the method that the suppliers or buyers arrange their own delivery or entrust a third-party logistics organization to deliver Way. In order to achieve high efficiency in cargo distribution, it is necessary to formulate a cargo distribution plan that takes into account various aspects such as logistics costs, delivery time, and delivery frequency.

The following uses the schematic diagram in Figure 1 to compare and describe the two conventional delivery methods.

For example, as shown in (a) and (b) of Figure 1, when goods are delivered from one or more suppliers (in the case of three suppliers in the figure: Supplier 1, Supplier 2, and Supplier 3) In the case of multiple buyers (company A and company B in the figure), (a) in Figure 1 adopts the traditional way of delivering goods individually to each buyer, and directly delivers the goods from each supplier to the buyer. Although this method can better comply with the delivery date of the goods, the number of distribution vehicles required is relatively large, and the empty-load rate of the distribution vehicles is high, resulting in waste of resources, high logistics costs, and inevitably lead to the buyer's The increase in the frequency of delivery further results in a waste of manpower and material resources; in addition, in the case of a sudden additional delivery such as temporarily increasing the delivery to a certain buyer, it is necessary to send a special delivery person separately Vehicles will also have the above-mentioned problems such as high empty load ratio.

In recent years, in order to further improve the logistics efficiency and realize the commonization of the logistics network, reduce the repeated business among the buyers to save costs, and at the same time deal with the situation of sudden additional delivery, the common delivery of multiple buyers (common delivery) is adopted. ), that is, a method of uniformly delivering goods required by multiple buyers (refer to Patent Document 1). To put it simply, as shown in (b) of Figure 1, Company A and Company B adopt a milk-run logistics method for joint delivery of goods from both parties. This delivery method reduces duplication among buyers. The business can greatly improve the efficiency of logistics, reduce the frequency of distribution and the empty load rate, and at the same time reduce the number of vehicles transported, so it can save transportation costs, thereby reducing the actual cost of buyers; and, in the above In the case of a sudden additional delivery, the temporarily increased delivery can also be performed by using a delivery vehicle that delivers to other buyers, thereby saving costs.

For example, assuming that in Figure 1, Company A and Company B both need 1 piece of goods from three suppliers, and there are two types of delivery vehicles, vehicle a and vehicle b, which can respectively load 1 piece of goods and 2 pieces of goods at a time. The fares for one use are 100 yuan and 150 yuan respectively.

In the case of traditional separate distribution in (a), company A needs three suppliers to send out car a at a cost of 300 yuan, and company B does the same, that is, the total cost is 600 yuan. To simplify the description, it is assumed here that the goods of Company A and Company B are delivered within one day, so that a delivery vehicle is delivered to the buyer's location once is one delivery, and the delivery frequency of Company A and Company B is 3 times/day. In the case of the joint distribution of circular pick-up in the figure (b), Company A and Company B adopt the joint delivery of circular pick-up. In order to save costs and avoid the waste of vehicle loading space, the best solution is to use three b-cars , obtain the goods from three suppliers and ship them to Company A and Company B respectively. The total cost is 450 yuan.

Regarding the distribution frequency in the case of (b), refer to (c) of FIG. 1 , which shows the situation in which three b vehicles are loaded with goods in the scheme of (b). Use A1 to represent the goods provided by Supplier 1 to Company A, A2 to represent the goods provided to Company A by Supplier 2, and so on. For example, let the three b cars used be loaded with goods A1 and A2, A3 and B1, B2 and B3 respectively, so the No. 1 car of b and No. Car No. 3 needs to be delivered to Company B once, so Company A and Company B each received two deliveries. It is also assumed that the goods of Company A and Company B are delivered within one day, and the delivery frequency of Company A and Company B is 2 times per day. It can be seen that compared with individual delivery, the use of joint delivery can minimize the empty load rate and transportation cost, and reduce the frequency of delivery.

This joint delivery method is widely used at present. For example, Patent Document 1 discloses a joint delivery auxiliary system for goods. According to the combination of goods information and vehicle allocation information, a combination that matches each other is specified for joint delivery. The vehicle allocation system connected to the Internet The management server formulates a car distribution plan with reference to the distribution order database, vehicle database, etc. for each co-distribution group that conducts joint distribution, and implements actual corrections to the vehicle distribution plan. On this basis, it calculates the freight and calculates the owner's respective Fees payable to the owner of the vehicle.

Contents of the invention

The problem to be solved by the invention

However, there are the following problems in the above common delivery:

In actual delivery, the delivery fee is often paid by the buyer. When formulating a specific delivery plan based on the above ideas, since it is a multi-party joint delivery, it is necessary to consider from the perspective of each buyer, taking into account the delivery costs, delivery time, and delivery frequency of all parties, so as to make a product that is satisfactory to all parties. distribution plan, this is difficult to achieve. This is because, generally speaking, from the point of view of the delivery party, the aim is usually to minimize the total transportation cost, but the delivery plan created in this way may be unfair to each buyer who pays the delivery fee. For example, when the total cost is the lowest, some buyers pay more while others pay less; Compared with the use of joint delivery, the cost is greatly reduced, and the cost reduction rate for another part of buyers is not high (that is, joint delivery does not bring obvious cost reduction to them); or, according to the final selected delivery According to the plan, the delivery period required by some buyers is strictly observed, while the delivery period of some buyers is not complied with; Buyers need to deliver many times. From the perspective of each buyer, a method of making a delivery plan that comprehensively considers delivery costs, delivery dates, and the fairness of delivery frequency has not yet been proposed.

Technical means to solve the problem

In order to solve the above-mentioned problems, the present invention provides a delivery plan making system for making a delivery plan for jointly delivering a plurality of goods from one or more suppliers to a plurality of buyers, which includes: delivery a plan generating unit that generates a plurality of vehicles that can be included in the vehicle allocation information based on the cargo information related to the cargo and the vehicle allocation information related to the vehicle that transports the cargo from the plurality of buyers; type and quantity to complete the delivery plan of the delivery amount contained in the goods information; the delivery fee calculation unit, for each of the multiple delivery plans, calculates the total delivery fee and the The delivery fee payable by each buyer among the multiple buyers; the fair rate calculation unit, for each of the multiple delivery plans, according to the cargo information and the vehicle allocation information, calculates the For each of the plurality of buyers mentioned above, the delivery date compliance rate indicating the compliance with the delivery date of the goods, the delivery frequency of the goods, and the delivery cost compared to the buyer's individual delivery are calculated by The cost of joint delivery is reduced, and based on the difference in the delivery fee payable by each buyer among the plurality of buyers, the difference in the compliance rate of the delivery period, the difference in the delivery frequency, and A fairness rate is calculated from the difference of the reduced costs; a judging part, which compares the fairness rate of each of the plurality of delivery plans with a preset threshold, to obtain the fairness rate greater than the threshold The delivery plan with the lowest total delivery cost among all the delivery plans is used as the preferred delivery plan; and a calculation result output unit that outputs the preferred delivery plan.

In the above delivery plan preparation system, the difference in the delivery fee payable by each buyer, the difference in the delivery period compliance rate, the difference in the delivery frequency, and the difference in the reduced cost can be calculated by calculating the standard difference, but the difference can also be obtained by other calculation methods.

In the above delivery plan making system, the fairness rate calculation unit further corrects the fairness rate according to the additional requirements from the multiple buyers, and the additional requirements can be delivery fee requirements and delivery period requirements, or other Requirements, such as requirements for delivery frequency.

In the above-mentioned delivery plan making system, the delivery fee calculation unit may calculate the delivery fee according to the weight of the goods, or calculate the delivery fee according to the type and number of vehicles transporting the goods, or calculate the delivery fee according to the weight of the goods. The distance traveled by the vehicle of the goods is used to calculate the distribution fee.

The present invention also provides a method for making a delivery plan for making a delivery plan, the delivery plan is used to jointly deliver multiple goods from one or more suppliers to multiple buyers, which includes: generating a delivery plan Step, according to the goods information related to the goods from the multiple buyers and the vehicle allocation information related to the vehicle transporting the goods, generate a plurality of vehicle types and quantities that can be included in the vehicle allocation information Complete the delivery plan of the delivery amount contained in the goods information; the delivery fee calculation step, for each of the multiple delivery plans, calculate the total delivery fee payable by the multiple buyers and the multiple The delivery fee that each buyer among the buyers should pay; the fair rate calculation step, for each of the multiple delivery plans, according to the goods information and the vehicle allocation information, for the multiple buyers Each of the calculations: the delivery date compliance rate indicating the compliance with the delivery date of the goods, the delivery frequency of the goods, and the delivery cost of the buyer compared to the delivery cost of the buyer's separate delivery. , and based on the difference in the delivery fee payable by each buyer among the plurality of buyers, the difference in the compliance rate of the delivery period, the difference in the delivery frequency and the reduced cost The fairness rate is calculated by the difference; the determination step is to compare the fairness rate of each of the plurality of delivery plans with a preset threshold, so as to obtain the fairness rate of all delivery plans that are greater than the threshold The delivery plan with the lowest total delivery cost is used as the preferred delivery plan; and the calculation result output step is to output the preferred delivery plan.

detailed description

Hereinafter, with reference to the accompanying drawings, the delivery plan making system and delivery plan making method of the present invention will be described through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. In addition, although the delivery plan creation system and delivery plan creation method of the present invention are introduced in conjunction with the embodiments, this does not mean that the features of the invention are limited to the embodiments. On the contrary, the purpose of introducing the invention in conjunction with the embodiments is to cover other options or modifications that may be extended based on the claims of the present invention. The following description contains numerous specific details in order to provide a clearer understanding of the present invention. The invention may also be practiced without these details.

In this embodiment, the case where buyer A and buyer B obtain goods A and goods B from supplier A and supplier B through joint delivery by a logistics organization is exemplified. However, the delivery party of the joint delivery is not limited to the logistics organization, and the delivery can also be arranged by the supplier or the buyer. In addition, there may be multiple suppliers or only one supplier. In this embodiment, the case of two suppliers is exemplified, and goods A comes from supplier A, and goods B come from supplier B. Moreover, in this embodiment, with regard to the delivery date compliance rate, delayed or advanced delivery dates are regarded as not complying with the delivery date, but the definition of the delivery date compliance rate is not limited to this, in real life, for example, according to each buyer It is also possible to consider the situation of leading the delivery period as compliance with the delivery period, so the delivery period compliance rate can be defined in many ways.

FIG. 2 is a block diagram showing each functional unit of the delivery plan preparation system according to the present embodiment. In FIG. 2 , delivery plan preparation system 100 includes control unit 10 , calculation unit 20 , storage unit 30 , communication unit 40 , and display unit 50 . Among them, the control unit 10 includes an input information receiving unit 110 , a determination unit 120 , and a calculation result output unit 130 .

FIG. 3 is a flowchart for explaining each step of the delivery plan preparation method in this embodiment.

First, the suppliers and buyers of goods use various e-commerce systems developed on the market to input the goods information related to the goods to be distributed and the vehicle distribution information related to the vehicles transporting these goods, and the distribution plan is carried out through the Internet or local area network. The input information receiving unit 110 of the production system 100 receives it. The input information receiving unit 110 makes the distribution order information table as shown in FIG. 4 according to the goods information related to the goods obtained from the buyer, and makes the distribution order information table as shown in FIG. The vehicle distribution information table shown, and the distribution order information table and the vehicle distribution information table are stored in the storage unit 30 (steps S1, S2).

As shown in FIG. 4 , the distribution order information table includes, for example, information such as order number, buyer name, name of goods to be delivered, delivery date required by the buyer, and required delivery volume. For example, the first row in Figure 4 represents the order numbered 001, and buyer A requests to receive 3 copies of goods A on January 1. As shown in Figure 5, the vehicle allocation information table includes, for example, the vehicle type (car model) of the delivery vehicle, the load capacity corresponding to the vehicle type, the transportation unit price that should be paid once using the vehicle, and the vehicle owned by the logistics organization. quantity. For example, the first line in Figure 5 indicates that the logistics organization owns 10 trucks A, each truck A can load 4 goods, and the price of each truck A is 30 yuan.

It should be noted that the delivery order information table and the car distribution information table are not limited to the above forms and contents, and can also be appropriately changed according to needs. For example, in Fig. 5, the loading capacity is displayed in the form of the quantity of goods, but it can also be expressed in weight units, for example, the loading capacity is 1000kg, 1500kg, etc.

The calculation unit 20 includes a delivery plan generation unit 210 for generating a delivery plan, a delivery cost calculation unit 220 for calculating delivery costs for each delivery plan, and a fair rate calculation unit 230 for calculating a fair rate. In step S3 of FIG. 3 , the delivery plan generation unit 210 generates a plurality of delivery plans based on the delivery order information table and the vehicle delivery information table stored in the storage unit 30 and stores them in the storage unit 30 . Among them, various methods in the prior art such as Patent Document 1 can be used to generate the delivery plan. The delivery plan generation unit 210 generates all possible delivery plans that can complete the delivery amount shown in FIG. 4 with the vehicle type and quantity in the vehicle allocation information table shown in FIG. The format of the delivery schedule shown in 6 is stored in the storage unit 30 .

A delivery plan in the delivery plan table in FIG. 6 will be described in detail below.

For example, consider delivery plan 1, for the order number 001, according to Figure 4, it can be seen that buyer A requires to receive 3 copies of goods A provided by supplier A on January 1, the first content of the table in Figure 6 Xing said that using the No. 1 vehicle of truck A with a loading capacity of 4, 3 shipments were delivered to the location of buyer A on January 1. As a result, the order number 001 was completed. For the order with order number 002, according to Figure 4, buyer A requests to receive 3 copies of goods A on January 2, referring to the second and third lines of the form in Figure 6, because the loading of No. 1 with 4 The truck only loaded 3 copies of goods A when order 001 was completed, so it used its vacant space to load 1 copy of goods A for order 002, and called the No. 2 truck of truck A to load 2 copies of goods, and delivered to The location of buyer A. As a result, the order number 002 was completed. Similarly, car No. 2 uses the remaining loading space for order 003 to load two copies of goods A, and so on, to allocate the delivery volume of orders 001 to 006.

In this embodiment, the delivery plan table as shown in Fig. 6 is exemplified to express the delivery plan, but the expression form and generation method of the delivery plan are not limited to this, for example, different goods are provided by different suppliers in this example, but It can also be provided by the same supplier.

After generating multiple delivery plans, the delivery fee calculation unit 220 calculates the total delivery fee payable by multiple buyers for each delivery plan in the delivery schedule table according to the vehicle unit price shown in the vehicle allocation information table of FIG. 5 (the sum of the delivery fees that each buyer should pay), the delivery fees that each buyer should pay in multiple buyers, and generate a delivery fee order table in association with each delivery plan, and store it in the storage unit 30 (step S4). The order table of delivery fees is shown in FIG. 7 , for example, the delivery fees of each delivery plan are listed in the order of total fees from low to high.

The specific calculation of the above-mentioned delivery fee will be briefly described below by taking the delivery plan 1 in FIG. 6 as an example. Regarding Buyer A, Cart 1 was used once when completing orders 001 and 002, Cart 2 was used once when completing orders 002 and 003, and Cart 3 was used once when completing Order 003 (with Buyer B’s The goods are shared); Regarding buyer B, when completing order 004, he used the No. Cart 5 was used again (not full). Therefore, buyer A should pay the full cost for car No. 1 and car No. 2, that is, 30×2=60 yuan, and pay a part of the cost for car No. 3. Here, for example, it is calculated according to the proportion of goods. Car No. 3 Among the 4 shipments, 1 is for buyer A and 3 is for buyer B. Therefore, buyer A pays 30×1/4=7.5 yuan, and needs to pay 60+7.5=67.5 yuan in total. Similarly, buyer B needs to pay 30×2+30×3/4=82.5 yuan in total. Among them, although the No. 5 car is not full, it still has to pay the full fee, and the empty load of the No. 5 car is wasted.

In the above calculation, in order to simplify the description, the distribution fee is determined by the type (model) and number of vehicles used. In the case of multiple buyers sharing the vehicle, the fee is allocated according to the proportion of the goods they belong to. However, the specific calculation method is not Not limited to this, for example, the delivery fee can also be calculated according to the weight of the goods (for example, the heavier the goods, the higher the cost), or let each delivery vehicle be equipped with a positioning device such as GPS to obtain the position of each vehicle in real time, thereby delivering When calculating the delivery fee, the fee calculation unit 220 performs the above-mentioned fee calculation for each delivery plan according to the vehicle unit price and the travel distance calculated based on the position of the above-mentioned vehicle (in the case of the same vehicle, the longer the travel distance, the more expensive the fee is). ). In addition, as in Patent Document 1, the cost of each vehicle can be calculated by comprehensively considering the cargo volume of each vehicle, delivery distance or loading/unloading workload, and then according to the actual data of driving, according to the cargo volume of each buyer and delivery distance, etc. to calculate the cost that each buyer should bear.

Next, in step S5, the fairness rate calculation unit 230 calculates a fairness rate for each delivery plan. Here, the fair rate is a concept defined according to KPI (Key Performance Indicator: Key Performance Indicator), which represents the difference in cost, delivery period, etc. between buyers, that is, the balance of satisfaction among buyers .

In this embodiment, the difference in the delivery fee that each buyer should pay among multiple buyers, the reduction ratio of the cost reduction through joint delivery (that is, the delivery fee that each buyer spends when compared to individual delivery) is considered. , through the adoption of common distribution, the distribution cost borne by each buyer is reduced), the difference in the delivery time compliance rate indicating the compliance with the delivery time of the goods, and the difference in delivery frequency. List these four differences in the table in Figure 8, and finally calculate the fairness rate.

The above four factors will be described below by taking the delivery plan 1 in FIG. 6 as an example.

Regarding the first item "delivery fee", as mentioned above, in delivery plan 1, buyer A needs to pay 67.5 yuan, and buyer B needs to pay 82.5 yuan.

Regarding the second item "reduction ratio", for buyer A, if the buyer A does not use joint delivery, but carries out separate delivery of the goods required by the buyer (the delivery shown in (a) of Figure 1), then only need to consider Orders 001, 002, 003 in Figure 4. In order to complete order 001, a truck A needs to be sent from supplier A on January 1 to load 3 copies of goods A. Similarly, on January 2 and January 3, a truck A is also sent from supplier A to load 3 copies of goods A cost 30×3=90 yuan in total. Compared with the distribution plan 1 in FIG. 6 , the cost reduction rate is (90-67.5)/90=25%.

For buyer B, in the same way, only need to consider orders 004, 005, and 006 in Figure 4 when performing separate delivery, which is the same as the above calculation, and the total cost is 30×3=90 yuan. Compared with the delivery plan 1 in FIG. 6 , the cost reduction rate is (90-82.5)/90=8.3%.

Regarding the third item "delivery period compliance rate", in Figure 4, buyer A has three orders in total, which require delivery on January 1, January 2, and January 3 respectively. Among them, the delivery volume of order 001 is All completed on January 1st, so the delivery period was complied with; the delivery volume of orders 002 and 003 were all completed on January 1st, the previous agreement is adopted here, and the delivery period ahead of schedule is also considered as failure to comply with the delivery Therefore, in the delivery plan 1, buyer A's delivery compliance rate is 1/3=33.3%. Similarly, for buyer B, only the delivery date of order 004 is complied with, and the delivery date of orders 005 and 006 is not complied with, and the compliance rate of the delivery date is 1/3=33.3%. Of course, if the delivery date agreed to be ahead of schedule is also considered to be in compliance with the delivery date, the calculation process is naturally different from the above.

Regarding the fourth item "delivery frequency", for buyer A, the No. 1, No. 2 and No. 3 trucks of truck A are all delivered to buyer A once on January 1, so the delivery frequency is 3 times /sky. For buyer B, the No. 3, No. 4 and No. 5 trucks of truck A are also delivered to buyer B once on January 1, so the delivery frequency is also 3 times per day.

Next calculate the "difference" item in Figure 8. In this embodiment, the number of buyers is 2, so to simplify the description, the calculation method of "difference/sum" can be used to calculate, expressed in the form of a percentage, for example, for the difference in delivery costs, buyer A and buyer The sum of the delivery costs of Home B is 150 yuan, and the difference between the two is 15 yuan, so the difference in delivery costs is 10%. However, the calculation method of the difference is not limited to this, and various existing calculation methods can also be used. For example, the standard deviation among the delivery costs of each buyer can be calculated, and a percentage value can be obtained after dividing by the average value.

The other three items also use the same method to calculate the difference, and fill in the last column of the table in Figure 8.

In this embodiment, the fair rate is defined as the value obtained by subtracting the average value of the above four items from 1, which is 1-(10%+50%)/4=85%. However, the definition of the fairness rate is not limited to this, and various existing calculation methods can also be used, for example, the fairness rate is defined as the value obtained by subtracting the product of the four differences from 1, etc.

In this embodiment, a threshold is set for the fairness rate, for example, 90%. However, the threshold is not limited thereto, and can be defined by the user of the delivery plan making system according to needs.

Next, for example, in accordance with the order of total delivery costs from low to high in FIG. The fairness rate of each distribution plan calculated in Fig. 8 is compared with the preset threshold value (step S6), if the fairness rate is less than the threshold value, then the comparison of the fairness rate of the delivery plan of the next sequence and the threshold value (step S6) Step S7), until the fair rate of the delivery plan is greater than the threshold, so as to obtain the delivery plan with the lowest total delivery cost among all the delivery plans with the fairness rate greater than the threshold, and determine it as the preferred delivery plan.

After obtaining the optimal delivery plan, the calculation result output unit 130 outputs a part of the delivery schedule table in FIG. 6 corresponding to the optimal delivery plan to the display unit 50 (step S8), and displays it on the display unit 50 (S9). At this point, the distribution plan preparation process ends.

In this embodiment, the calculation result output unit 130 only outputs the first delivery plan whose fairness rate is greater than the threshold (that is, the delivery plan with the lowest total delivery cost among the delivery plans whose fairness rate is greater than the threshold) to the display unit 50 for display. The 1st, 2nd, ... nth delivery plans whose fairness rate is greater than the threshold can be sent to the display unit 50 as the preferred delivery plan for display, and then the user can decide which delivery plan to use according to actual needs.

Also, different buyers may have different additional requirements for shipping. For example, some buyers will require that the delivery fee paid cannot exceed a set value, and some buyers will require that the delivery period must be fully complied with, and so on. In this case, the additional requirements of each buyer, such as the above-mentioned delivery fee requirements and delivery period requirements, can be included in the calculation of the fair rate.

For example, as shown in (a) of FIG. 9 , when buyer B has requested that the delivery fee cannot exceed 80, for delivery plan 1, the fair rate calculation unit 230 calculates the fair rate according to the buyer If B's delivery fee does not meet the delivery fee requirement, set the fairness rate to 0. Similarly, as shown in (b) of FIG. 9 , when buyer A requires that the delivery period must be fully complied with, the fair rate calculation unit 230 calculates the fair rate based on buyer B's delivery date If the compliance rate does not meet the delivery period requirement, the fairness rate is set to 0. These two situations indicate that the delivery plan is extremely dissatisfied for a certain buyer, so the fairness rate is 0, thereby preventing it from being selected as the preferred delivery plan.

To sum up, the distribution plan preparation system of the present invention takes into account the differences in the distribution costs of each buyer, the compliance with the delivery date, and the distribution frequency, and screens multiple distribution plans according to the size of the fairness rate, so as to be able to take into account Fairness in terms of delivery costs, delivery deadlines, and delivery frequency among buyers creates a delivery plan that satisfies multiple buyers.

The above embodiments are only illustrative to illustrate the principles and effects of the present invention, but are not intended to limit the present invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
