Description

  The present invention relates to an estimate support system, and more particularly to an estimate support system that takes into account a part price that varies depending on an ordering form.

  Estimating manufacturing costs and product costs is an essential task in daily manufacturing and sales activities. The accuracy of the estimate is greatly influenced by the performance of the software for which the estimate is made, the accuracy of the material cost required for manufacturing, the cost of the parts constituting the product, and the like. Usually, when cost estimation is performed, an approximate cost is obtained based on past results. Furthermore, when more detailed cost management than the estimated cost is required, a new calculation is performed using another software. Therefore, Patent Document 1 discloses a cost estimation system that can calculate the cost for each of a plurality of parts constituting a product by rough estimation and can estimate detailed costs for necessary parts. That is, a cost estimation system including an approximate cost estimation device and a detailed cost estimation device, wherein the approximate cost estimation device is a component cost based on past results for each of a plurality of parts constituting a product, The detailed cost estimation apparatus includes a cost result database storing first cost data indicating assembly costs required for assembling a plurality of parts based on past results, and the detailed cost estimation device includes a material, a shape, and a processing method for each of the plurality of parts. It is described that the second cost is automatically calculated according to the change of at least one of the conditions.

  In addition, the accuracy of the product cost estimate greatly depends on whether the product is an ordered product or a mass-produced product. In order to obtain an order from the customer, the product price is first estimated, and the estimated price is shown to the customer and negotiated to determine the final product price.

  However, in the case of the above-described estimation of the ordered product, when time elapses from the time when the estimation is performed, the original cost varies due to fluctuations in the work unit price and parts price. Therefore, it is necessary to present the estimated expiration date for guaranteeing the amount together with the estimated price to the customer.

  Patent Document 1 describes a mechanism of a cost estimation support system using a computer. In this document, a part price based on past results is obtained for parts constituting a product, and the product price is estimated by summing up the part prices. Therefore, the parts price is fixed because of past performance. However, the part price may fluctuate depending on the ordering form, and there is a problem that this is not taken into consideration.

  Accordingly, an object of the present invention is to provide an estimation support system that performs accurate price estimation in consideration of a part price that varies depending on an ordering form.

  In order to achieve the above object, the main configuration of the estimation support system of the present invention is as follows.

  An estimate support system that takes into account the price of parts that fluctuates depending on the order form, and consists of an operation unit that inputs information necessary for estimation, a part order schedule calculation part, and a part price fluctuation schedule calculation part, and executes estimate calculation An estimate calculation unit, a product ID assigned to the product, a design BOM storage unit that stores information including a component ID of a component used in the product, a component information storage unit that stores component information about the component, A display unit that displays an estimated price fluctuation schedule calculated by the estimate calculation unit, and a product to be estimated by the user and a product delivery date of the product are input to the operation unit. Based on the product, the base schedule and base price for each part of the product are calculated, the part ordering schedule is calculated from the part procurement period set for each part based on the product delivery date and part information, and the part price change date The calculation unit compares the first component procurement period calculated based on the part order schedule with the second component procurement period calculated based on the reference schedule for each part, and the first component procurement period is the first component procurement period. For the parts shorter than the parts procurement period of 2, the price for the increase in express speed set according to the second parts procurement period is acquired from the parts information storage unit, and corresponds to the second parts procurement period For each part to be processed, the price for the speed increase is added to the reference price to calculate the speed limit estimated price and present the estimated expiry date of the speed limit estimated price.

  According to the present invention, it is possible to provide an estimation support system that performs accurate price estimation in consideration of fluctuations in component prices.

If the estimate is complete, it will end.

  FIG. 5 illustrates and explains the concept of part order schedule calculation for one part.

  First, the fluctuation of the part purchase price depending on the ordering form will be described below.

  The general process for manufacturing an order-made product starts with the order decision from the customer as the starting point, the design process for designing the product, the arrangement process for ordering the parts required for manufacturing after receiving the design, Procurement process for producing and delivering products, and manufacturing processes for producing products using the procured parts and delivering them to customers.

  If the period from when the order is determined until the product is delivered to the customer (product delivery time) is short, each process must be shortened.

  In order to shorten the procurement process, a part is ordered as a so-called limited express product in which the period from part ordering to delivery is shorter than usual.

  When a part order is placed as an express product, the parts manufacturer of the ordering party processes or processes the document processing or manufacturing of other parts, and preferentially processes the express product.

  Therefore, the express product forces the parts manufacturer to perform inefficient work, and the part price is an additional cost added to the normal price.

Such additional costs increase in relation to the short parts procurement period (short delivery time), but increase rapidly especially after a certain period.
In order to obtain an accurate estimated price, it is necessary to obtain an estimated expiration date that takes into account the rise in the express price and the price fluctuation schedule as fluctuations in procurement costs.
In addition, when applying parts that have been designed in the past to products, a design document has already been made, so there is no need to design. Therefore, the design process is omitted, and it is necessary to obtain a price fluctuation schedule that takes into account the design process, that is, an estimated expiration date.

FIG. 5 shows the progress of the date on the horizontal axis. The left end is now 506 and the date progresses as it goes to the right.
As the time elapse, the design starts on the date 501, the design period 502 elapses and the design is completed, the arrangement is started, and the date when the arrangement period 503 elapses and the arrangement is completed becomes the parts order date 507. When the procurement period 504 elapses from the part ordering date 507, the part arrives at the manufacturing and the manufacturing starts. The date when the manufacturing period 505 elapses and the manufacturing ends is the product delivery date 508.

  In the first embodiment, an example of an estimation support system that is reflected in the estimated price fluctuation schedule when there is no design record for each part will be described. State.

    First, a part order date 507 is obtained. A date that goes back the sum of the manufacturing period 505 and the procurement period 504 from the product delivery date 508 is a part ordering date 507.

    Next, an express expiry date 509 is obtained. The date after the sum of the design period 502 and the arrangement period 503 from the part order date 507 is defined as the express expiry date 509.

FIG. 6 illustrates and explains the concept of calculating the estimated price fluctuation schedule for one part.
FIG. 6 shows the progress of the date 601 on the horizontal axis and the price 602 on the vertical axis. The left end is now 603, the date progresses as it goes to the right, and the price increases as it goes up.
The express expiry date 606 is obtained from the product delivery date 608 as described in FIG.
The reference price 604 is a fixed amount regardless of the date, the part price 607 is 0 on the date before the express expiry date 606, and the part price 605 is the same value as the reference price 604. On the other hand, when the expedited expiry date 606 is passed, an expedited price increase 605 is generated, and a value obtained by adding the expedited price increase 605 to the base price 604 becomes a parts price 607.

FIG. 7 illustrates and explains the concept of the estimated price fluctuation schedule of a product.
The example of FIG. 7 is a conceptual diagram in which the fluctuation of the estimated price of the product M01 is calculated using the data of the three parts C01, R01, and S01 shown in FIG.
FIG. 7 shows the progress of the date 701 on the horizontal axis and the price 702 on the vertical axis. The left end is now 703, the date progresses as it goes to the right, and the price increases as it goes up.
The express expiry dates 711, 712, and 713 are obtained from the product delivery date 708 as described above with reference to FIG.

First, the sum of reference prices for each part is obtained and set as a reference price sum 704. The reference price sum 704 is the sum of the reference prices of the three parts shown in FIG. 3 and is ¥ 2,400,000.
Next, the express price increase 705 of each part is added to the reference price sum in order from the part whose express expiry date is close to the present, and the sum is set as the estimated price 707.

  In FIG. 7, the component that is the closest expedited deadline is C01 (711), the date is the expedited expiry date 1 (721), and the estimated price 707 at that time is the amount of the expedited increase in the reference price sum 704. 1 (731) plus ¥ 2,900,000. Next, the part that is the expedited expiry date close to the present is R01 (712), the date is expedited expiry date 2 (722), and the estimated price 707 at that time is the expedited increase 1 in the reference price sum 704. It is ¥ 3,300,000 obtained by adding (731) and the express increase 2 (732). Next, the part with the expedited expiry date close to the present is S01 (713), the date is expedited expiry date 3 (723), and the estimated price 707 at that time is the reference price sum 704 with the expedited increase 1 ( 731), the speed increase 2 (732) and the speed increase 3 (733) are ¥ 3,600,000.

  That is, in the example of FIG. 7, the estimated price 707 fluctuates depending on the expedited expiry date 1, expedited expiry date 2 and expedited expiry date 3 as the date, whereas the base price sum 704 is ¥ 2,400,000 , ¥ 2,900,000, ¥ 3,300,000, ¥ 3,600,000, respectively.

FIG. 8 shows an example of the display screen of the operation unit 101.
The display screen 800 displays a product ID 801, a product delivery date 802, an estimated price table 803, and an estimated price fluctuation schedule diagram 804. Here, the case of M01 is shown as the product ID, and the estimated price fluctuation schedule 804 is shown in FIG. In the estimated price list 803, data of the list shown in FIG. 3 and a value calculated from “2011.03.30” of the product delivery date 802 are displayed.

FIG. 9 shows an example of an estimated price list displayed on the operation unit 101.
The estimated price list 900 indicates the estimated expiration date 901, the estimated price 902, and the component 903 that caused the fluctuation vertically, and a set of values corresponding to the estimated expiration date 901 is described as an estimated plan 904 on the side. ing.

  In the example of FIG. 9, the estimated price 902 is ¥ 2,400,000 if the estimated expiration date 901 is up to 2011.12.30, and the estimated price 902 is up to if the estimated expiration date 901 is up to 2011.11.14. If the estimated expiration date 901 is up to 2011.2.3, the estimated price 902 is ¥ 3,300,000.

FIG. 10 shows an example of an estimated price fluctuation schedule displayed on the operation unit 101.
FIG. 10 is based on the estimated price fluctuation schedule shown in FIG.
In the estimated fluctuation schedule 1000, the horizontal axis indicates the progress of the date 1001, and the vertical axis indicates the price 1002. The left end is currently 1003, the date progresses as it goes to the right, and the price increases as it goes up.
The express expiry dates when the estimated price 1007 fluctuates are displayed as 1004, 1005, and 1006, respectively.

In addition, it is indicated that the parts that are the variation factors of the express expiry dates 1004, 1005, and 1006 are C01 (1008), R01 (1009), and S01 (1010).
In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.

Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.

  In the present embodiment, an example of an estimation support system that reflects the presence or absence of design results in individual parts in the estimated price fluctuation schedule will be described.

FIG. 11 is obtained by adding the item 1110 of presence / absence of design results to the component information in the component information storage unit 104.
In the present embodiment, C01 (1107) is present as design results, R01 (1108) is present, and S01 (1109) is absent.
In this case, since the design of the part S01 (1109) is not necessary, it is necessary to exclude the planning period for S01 when calculating the part order schedule.

  That is, in this embodiment, since C01 (1107) has a design record 1110 of “present”, the design period of 50 days is excluded from the plan period. Therefore, only the arrangement period: 10 days, the procurement period: 25 days, and the production period: 5 days are added as the planning period. The reference price: ¥ 1,000,000 and the limited express price increase: ¥ 500,000 are the same as those in the first embodiment. Also, R01 (1108) has a design record 1110 of “Yes” in the same way as C01 (1107), so the design period of 40 days is excluded from the planning period. Therefore, only the arrangement period: 10 days, the procurement period: 20 days, and the production period: 5 days are added as the planning period. The base price: ¥ 800,000 and the limited express price increase: ¥ 400,000 are the same as those shown in the first embodiment.

  In S01 (1109), since the design record 1110 is “None”, the design period 25 days is added to the plan period together with the arrangement period: 10 days, the procurement period: 15 days, and the production period: 5 days. Is done. The base price: ¥ 600,000 and the limited express price increase: ¥ 300,000 are the same as those in the first embodiment.

  If the example of the part information storage unit shown in FIG. 7 is applied here, the part that is the nearest expedited deadline closest to the present is S01 (1109), and 2011.2.3 is the expedited deadline 1 is there. Next, the part that has an expedited expiry date close to the present is C01 (1107), and 2011.1.28 is expedited expiry date 2. Next, the part that has an expedited expiry date close to the present is R01 (1108), and 2011.1.23 is expedited expiry date 3.

  The estimated price at that time is the same as that described in the first embodiment in which the speed increase is added to the base price sum.

  Note that FIG. 7 is used as a drawing corresponding to this description.

FIG. 12 shows the processing flow of the present embodiment in consideration of the presence of design results.
Note that steps S001 to S002 and steps S006 to S009 are the same as in the embodiment, and steps S003 to S005 are replaced with the following flow.
Step S101 (part information acquisition):
Based on the component IDs C01, R01, S01,... Which are the component IDs acquired in S002, the estimate calculation unit 102 stores the reference price corresponding to each component ID from the component information storage unit 104, the express price increase amount, the express expiry date, Acquire the design period, arrangement period, manufacturing period, procurement period, and design results.
Step S102 (determination of presence / absence of design of parts):
Step S103 for determining the presence or absence of design results (calculation of parts ordering schedule with design results):
The part order schedule calculation 105 calculates the part order schedule for each part based on the expedited expiry date, design period, arrangement period, manufacturing period, procurement period, and product delivery date corresponding to the acquired part ID.
This is equivalent to the actual example 1.
Step S104 (parts order schedule calculation without design results):
The part order schedule calculation 105 calculates the part order schedule for each part based on the expedited deadline, arrangement period, manufacturing period, procurement period, and product delivery period corresponding to the acquired part ID.
That is, the expedited expiry date 509 is calculated excluding the calculation that goes back the design period 502 in FIG.
Step S105 (determination of whether all parts have been calculated):
The design performance determination S102, part order schedule calculation S103 or S104 is sequentially performed for all parts.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.
