Description

  The present invention relates to a material purchase order destination determination apparatus that automatically determines a purchase order destination of materials according to estimates from a plurality of applicants (hereinafter referred to as order-receiving companies), and in particular, a large amount of materials of the same item. The present invention relates to a material purchase ordering party determination device, a material purchase ordering party determination system, a material purchase ordering party determination method, and a material purchase ordering party determination program.

  Generally, when an orderer or an orderer side company (hereinafter simply referred to as an orderer side company) who wants to purchase a material purchases a material, a delivery date may be determined in advance for the delivery of the material. That is, there is a case where the orderer side company orders the material from the contractor side company by designating the delivery date. Furthermore, estimates may be collected from a plurality of contractor side companies, the contractor side company that submitted the cheapest estimate may be determined as a material supplier, and an order for material purchase may be placed with the material supplier (multiples) To purchase materials from the cheapest company by competing with the contractor's company).

  By the way, if the orderer company estimates to multiple contractor companies in order to purchase a large quantity of materials for the same item, it is possible to arrange all quantities at each contractor company. However, as a result, it may not be possible to collect estimates from all contractor companies. For example, there is a contractor side company that can provide materials only about a few percent of the total quantity by the delivery date, and such a contractor side company cannot submit an estimate.

  Furthermore, if all the quantities can be prepared only in one contractor side company, the competition principle does not work, resulting in a higher unit price of materials. In other words, if the entire quantity is ordered from the order-receiving company that can deliver the entire quantity by the delivery date, the competition principle does not work and the unit price of the material becomes high.

  In order to deal with such problems, for example, the orderer side company divides all necessary quantities in advance and requests a plurality of contractor side companies to make an estimate for each divided quantity to work the competition principle. Things are also done. In other words, if you request an estimate by dividing the entire quantity and specifying a delivery date for each divided quantity, there is less chance that the quantity will not be aligned even if the delivery date is specified. As a result, the competition principle works. be able to.

On the other hand, a competitive trading system that buys and sells objects that can be distributed via a homepage is known. Here, the server notifies the client of the trading object, and the client sets the distribution range of the trading object and the distribution range. There is a technique in which a plurality of strategy information including a corresponding desired price is determined by a participant and the server is notified of the strategy information. In this case, the server notifies all clients of all the strategy information notified from the client, and the client causes the participant to determine one strategy information among the plurality of strategy information determined by the participant. The server notifies the client of the successful bid result (see, for example, page 4 of FIGS. 1 to 6 of Patent Document 1).

  However, when all the quantities are divided as described above and an attempt is made to request quotations from a plurality of order-receiving companies for each divided quantity, the entire quantity is originally estimated for a plurality of order-receiving companies collectively. The request was made to avoid the situation where all the quantities could not be prepared by the delivery date, that is, to avoid the situation where the competitive principle did not work. Depending on the material, a large number of companies on the order-receiving side may not be collected. As a result, it becomes difficult to exercise the principle of competition.

  In addition, if the split quantity specified by the ordering company is less than the maximum quantity that can be delivered by each ordering company, generally, it will tend to be cheaper due to the so-called economies of scale when ordering large quantities of the same material. If there is a certain thing, the purchase unit price of materials will become expensive. Further, even when requesting an estimate by dividing as described above, there is a problem that the merit of scale does not work and the unit price becomes high, and it becomes impossible to purchase a large amount of materials at low cost.

  In addition, when an estimate request is made by dividing a large amount of materials, there is a problem that the estimate matching becomes extremely troublesome and it takes time to determine the final purchase destination. In other words, it is difficult to improve the business efficiency in the orderer side company.

Since the decision is made, it is possible to place an order for purchasing a large amount of materials of the same item at a low price by using the merit of scale, and it is possible to improve the business efficiency of the orderer side company.

  Hereinafter, an example of a material purchase order destination determination apparatus and a material purchase order destination determination system according to an embodiment of the present invention will be described. First, referring to FIG. 1, a material purchase order destination determination device (hereinafter simply referred to as an order destination determination device) 11 is connected to a network 12 such as the Internet, for example, and the network 12 includes a plurality of terminal devices. 13-1 to 13-N (N is an integer of 2 or more) are connected. In the illustrated example, the ordering party determination device 11 is arranged in the orderer side company, and the terminal devices 13-1 to 13-N are the contractor side companies (for example, when N = 5, they are suppliers). Company A to Company E).

  Then, when the contractor-side company places an order for purchasing the material, as will be described later, an estimate describing the material quantity and the material unit price (delivery unit price: estimated amount) is submitted. This estimate is sent via the network 12 to the orderer-side company, that is, the order-destination determination device 11 using the terminal device 13-n (n is any integer from 1 to N). This estimate needs to be sent to the orderer company within the estimate reception period set by the orderer.

  The company on the orderer side examines the financial structure of the company that wishes to receive an order for materials in advance and issues a material orderer identification number (hereinafter simply referred to as ID) to the company that has passed this examination. At the same time, these IDs are stored in a memory unit (not shown in FIG. 1) in the order receiving party determining apparatus 11 in association with the company name. Then, as will be described later, the company that submits the estimate inputs the ID from the terminal device 13-n and then sends the estimate to the order-destination determination device 11.

  Here, referring to FIG. 2, the supplier determination apparatus 11 is, for example, a computer system, and includes a communication control unit 21, an input unit 22 such as a keyboard and a scanner, an estimation condition setting unit 23, an estimation request / reception unit 24, A memory unit 25, an estimated content list generation unit 26, a competition result generation unit 27, and an output unit 28 such as a monitor and a printer are provided. The memory unit 25 stores the company name and ID described above.

  In the orderer side company, from the input unit 22, the purchase quantity (total purchase quantity) P, range setting quantity Q (purchase quantity P) of materials to be purchased (for example, material specifications (hereinafter simply referred to as material names)) For example, when the purchase quantity P = 5000, the range setting quantity Q = 500 units is input, and it is desirable that Q <P and Q is an integer divisor excluding 1 of P) Enter the number of successful bidders, the estimated upper limit (unit price upper limit), the estimated receipt deadline, and the estimate request destination. As a result, the estimation condition setting unit 23 sets the estimation condition and passes it to the estimation request / reception unit 24.

  Specifically, the estimation condition setting unit 23 defines the set quantity according to the purchase quantity P and the range set quantity Q described above. This set quantity is a quantity arranged in the order of Q, 2 × Q, 3 × Q,..., M × Q (M is an integer of 2 or more). The estimate condition setting unit 23 passes the material name, the set quantity, the number of successful bidders, the estimate upper limit value, and the estimate reception deadline to the estimate request / reception unit 24 as the estimate conditions, and sets the estimate request destination to the estimate request / reception unit. Pass to 24. In the estimate request receiving unit 24, the communication control unit 21 sends the estimate conditions to the contractor side company indicated by the estimate request destination via the network 12 (FIG. 1).

  In the order-receiving company, an estimate which will be described later is created according to the estimate condition, and is sent to the order-destination determination device 11 via the network 12 by the terminal device 13-n, for example. In sending an estimate, it is necessary to access the order-destination determination apparatus 11 and first input the above-mentioned ID to authenticate the terminal apparatus 13-n.

  When the estimate request / reception unit 24 receives the estimate (estimate data), the estimate is associated with the ID and stored in the memory unit 25. Then, when the above-described estimate receipt deadline has passed, the estimate request / reception unit 24 notifies the estimate content list generation unit 26 to that effect. Upon receiving this notification, the estimate content list generation unit 26 reads each estimate from the memory unit 25, generates an estimate content list to be described later, stores it in the memory unit 25, and passes it to the competition result generation unit 27.

  The competition result generation unit 27 generates a competition result, which will be described later, based on the estimate content list, and outputs the competition result (that is, the supplier list) from the output unit 28 and stores it in the memory unit 25. When an ordering party sending command is input from the input unit 22, the competition result generation unit 27 sends the business partner (ordering party) indicated by the competition result in the memory unit 25 via the network by the communication control unit 21. You may make it do.

  Further, the above quote request may be made by mail or fax, and in this case, the quote is sent from the client to the ordering company by mail or fax. In this case, when the orderer's company inputs the estimate of each request destination from the input unit 22, the estimate request / reception unit 24 stores the estimate in the memory unit 25 in association with the ID.

  Here, with reference to FIG. 2 to FIG. 6, a description will be given of a case where an ordering party of a protection cast iron pipe (hereinafter simply referred to as an iron pipe) associated with new construction of a submarine cable is determined as a material. Here, it is assumed that the purchase quantity P = 5000 pieces, the range setting quantity Q = 500 pieces, and the quotation request destinations are five companies from A company to E company. In addition, there is no setting of the number of successful bidders, and the estimated upper limit value is set at 10,000 yen / piece. Note that the estimation is performed at a unit price per piece.

  As described above, an estimation condition is input (step S1), and an estimate request destination is input (step S2). As a result, the quote request / reception unit 24 transmits the estimate condition to the estimate request destination via the communication control unit 21 (step S3), and enters the estimate reception waiting state (step S4). The quotation request / reception unit 24 monitors whether or not the quotation reception deadline has been reached (step S5). When the quotation reception deadline has been reached, the quotation request / reception unit 24 has received at least one quotation. Is determined (step S6).

  If the quotation request / reception unit 24 has not received any quotation by the deadline for receipt of the quotation, the orderee determination apparatus 11 stops processing. On the other hand, if the estimate request / reception unit 24 has received at least one estimate by the deadline for receiving the estimate, the estimate content list generation unit 26 generates an estimate content list according to the estimate stored in the memory unit 25 ( Step S7).

  FIG. 5 is a diagram illustrating an example of an estimate content list. In this example, an estimate content list is created in a state where quotes are received from all of the A company to the E company. As shown in FIG. 5, since P = 5000 and Q = 500 here, the set quantity is arranged in increments of 500 in the order of 500, 1000, 1500,... .

  Each of Company A to Company E creates an estimate by describing the estimated amount (delivery unit price) for each set quantity that can be ordered by each company. Then, the estimate content list generation unit 26 combines these estimates to create an estimate content list (a list showing the unit price (estimated amount) of each company for each set quantity) shown in FIG.

  In the example shown in FIG. 5, it is shown that Company A can deliver up to 5000 purchase quantities, and the minimum unit price is 8000 yen. Company B can deliver up to 3000 pieces, and the minimum unit price is 7600 yen, and Company C can deliver up to 5000 pieces, and the minimum unit price is 9000 yen. Similarly, in Company D and Company E, the maximum deliverable quantities are 1000 pieces and 2500 pieces, respectively, and the minimum unit prices are 7700 and 7800 yen.

  When the estimate content list is created as described above, the competition result generation unit 27 creates (generates) a competition result as follows. First, the competition result generation unit 27 searches the estimated quantity list for the highest quantity R and the business partner among the set quantities with the purchase price = the set quantity P = 5000 or less and the lowest unit price (estimated amount) (step S8). . In the estimate content list shown in FIG. 5, since company B has the cheapest unit price of 7600 yen and its maximum quantity R = 3000, company B's unit price = 7600 yen and maximum quantity R = 3000 are selected.

  Thereafter, the competition result generation unit 27 determines whether or not the above-described unit price exceeds the estimated upper limit value = 10000 yen (step S9). The information is output to the output unit 28.

  On the other hand, if the estimated upper limit value is not exceeded, the competition result generation unit 27 determines whether or not the maximum quantity R <the purchase quantity P (step S10), and if R = P, the later-described step S24 is performed. Execute. Here, since the maximum quantity (set quantity) R = 3000, the competition result generation unit 27 determines whether or not the number of successful bidders has been reached (step S11). Then, if the number of successful bidders has been reached, the orderee determination device 11 stops the processing and outputs a message to that effect to the output unit 28.

  Here, since the number of successful bidders is not set, it is determined whether there is another business partner in the estimate content list other than the business partner searched in step S8 (step S12). Otherwise, the ordering party determining device 11 stops the processing and outputs a message to that effect to the output unit 28. In the example shown in the figure, estimates have been submitted from 5 companies from Company A to Company E, so the competition result generation unit 27 does not exceed the set quantity (PR), except for Company B searched in step S8. Then, the maximum quantity S and the business partner of the set quantity with the cheapest estimated price are searched from the estimate content list (step S13).

  In the illustrated example, (P−R) = 2000, and in the estimate content list shown in FIG. 5, when the set quantity is 2000 or less, Company D has the lowest unit price of 7700 yen and the maximum quantity R = 1000. Therefore, the unit price of company D = 7700 yen and the maximum quantity S = 1000 are selected.

  Thereafter, in step S14, it is determined whether the unit price has exceeded the estimated upper limit value, and then it is determined whether (set quantity R + set quantity S) <purchase quantity P (step S15). If (R + S) <P is not satisfied (that is, (R + S) = P), step S24 described later is performed.

  On the other hand, if (R + S) <P, it is determined in step S16 whether or not the number of successful bidders has been reached, and then in step S17, it is determined whether or not another supplier exists in the estimated content list. The

  And the competition result production | generation part 27 remove | excludes the B company and D company which were searched by step S8 and S11, and below the set quantity (PRS) and below the set quantity with the cheapest estimated price, the highest quantity T Then, the business partner is searched from the estimate content list (step S18). In the example shown in the figure, (P−R−S) = 1000, and in the estimate content list shown in FIG. 5, when the set quantity is 1000 or less, Company E has the lowest unit price of 7850 yen and the highest quantity R = Since it is 1000, the unit price of company E = 7850 yen and the maximum quantity T = 1000 are selected.

  Subsequently, in step S19, it is determined whether or not the unit price has exceeded the estimated upper limit value, and then it is determined whether or not (set quantity R + set quantity S + set quantity T) <purchase quantity P (step S20). ). If (R + S + T) <P is not satisfied (that is, (R + S + T) = P), step S24 described later is performed.

  On the other hand, if (R + S) <P, it is determined in step S21 whether or not the number of successful bidders has been reached, and then in step S22, it is determined whether or not another supplier exists in the estimated content list. The Then, as described above, the same processing as described above is repeated until the total of the set quantities reaches the purchase quantity P (step S23).

  In the estimated content list shown in FIG. 5, since (R + S + T) = 5000 = P in step S20, the process proceeds from step S20 to step S24.

  As described above, the competition result generation unit 27 generates a set quantity of 3000 at a unit price of 7600 yen for company B, a set quantity of 1000 at a unit price of 7700 yen for company D, and a set quantity of 1000 at a unit price of 7850 yen for company E. When selected, the winning bidders are B, D, and E, and the unit price is the contract amount and the set quantity is the purchase quantity (order quantity) for each supplier. 6 is obtained (contract amount for each supplier), and a total sum of the contract amounts for each supplier is obtained to generate the competition result shown in FIG. Then, the competition result generation unit 27 outputs the competition result to the output unit 28 (step S25) and stores it in the memory unit 25.

  In this way, the set quantity is specified up to the purchase quantity in the preset range set quantity increments, the supplier related to the highest set quantity that becomes the lowest price with the set quantity less than the purchase quantity is selected, and then, Select the supplier with the highest set quantity that is the lowest set quantity less than the remaining purchased quantity after subtracting the selected set quantity from the purchased quantity, and perform the above process until the purchased quantity is reached As a result, the principle of competition can be used to make the total price the cheapest and to ensure the purchase quantity.

  In other words, referring to the estimate contents list, search for the estimated amount sequentially from the cheapest estimated amount, obtain the set quantity and business partner corresponding to the found estimated price, and the sum of these obtained set quantities is When the purchase quantity is reached, the business partner determined by the retrieved estimated price and the set quantity corresponding to the estimated price is determined as the material supplier. In this way, the competition principle is used and the total price is the cheapest. In addition, the purchase quantity can be surely secured.

  Furthermore, since the above calculation is automatically performed to determine the ordering party, that is, the contracting party, the ordering work can be efficiently performed even when purchasing the same item in large quantities with a limited deadline. There is an effect that can be.

  As is clear from the above description, in the above-described embodiment, the estimated content list generating unit 26 functions as an estimated content list generating unit, and the competition result generating unit 27 functions as a searching unit and a determining unit. The input unit 22 and the estimation condition setting unit 23 function as an estimation condition setting unit, and the competition result generation unit 27 and the output unit 28 function as an output unit. Then, the quotation request / reception unit 24 and the communication control unit 21 function as transmission / reception means.
