DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cost estimating apparatus, and more particularly to a cost estimating apparatus suitable for estimating a cost in a design stage of device development.

[0002]

2. Description of the Related Art As a conventional technique for estimating the cost of a product, there is a cost estimating apparatus (hereinafter, referred to as a conventional apparatus) described in Japanese Patent Application Laid-Open No. 4-281554. In this conventional equipment, the cost is estimated by referring to the part unit price and machining cost file in which the unit price and machining cost are registered, using the production plan development result, and the estimated cost is compared with the actual cost using cost matching means. Then, when the result is within an allowable range, the estimation result is registered.

[0003]

By the way, in the above-mentioned conventional apparatus, when the unit price of a part necessary for cost estimation is not registered in the part unit price / machining cost file, a message to that effect is output and the message is output. The unit price of such parts is estimated as 0. Therefore, the user needs to inquire the unit price of the part whose price has been set to 0 to a part maker or the like, check the material at hand, determine the unit price, and re-estimate the price in consideration of the determined unit price. In this case, in the conventional device, since there is no mechanism for accumulating the unit price of the component that the user has self-examined in this way and providing the unit for later use,
There has been a problem that a unit price of a component that a user has investigated cannot be used for subsequent cost estimation of the same user or another user. It is also conceivable to newly register the checked price in the part unit price / machining cost file. However, since it is generally necessary to register the exact unit price based on the actual purchase results in the part unit price / machining cost file, There are many problems in registering a price investigated by a user for a new part with no track record in a part unit price / machining cost file.

Accordingly, a first object of the present invention is to provide a cost estimating apparatus having a function of accumulating a price obtained by a user for a part for which a price has not been registered so that the price can be effectively used in a later estimation calculation. Is to do.

[0005] Further, since prices of semiconductor parts and the like fluctuate greatly, prices based on purchase results often do not match the current state. In particular, the estimation at the setting stage is desirably based on the price at a point three months or six months before the parts are actually used, so that the estimation based on the actual price increases the error.

Accordingly, a second object of the present invention is to provide a cost estimating apparatus capable of estimating a cost by preferentially using a predicted price registered by a user over an actual price.

It is a third object of the present invention to provide a cost estimating apparatus in which a user can register a predicted price for each of a plurality of purchase periods and estimate a cost for each future period.

[0008]

According to a first aspect of the present invention, there is provided a cost estimating apparatus comprising: an actual price storage unit for retaining price information of a part which has been purchased in order to achieve the first and second objects; A new price storage unit that holds the price information of parts independently of the actual price storage unit ;

There is a search condition that gives priority to the new price storage unit. Previous
If the search condition of the user is registered, the following operation will be performed.
You. That is, when the user inputs a bill of materials for which cost estimation is to be performed from an input device such as a keyboard or a file device or the like, the bill of material is acquired by the bill of material acquiring unit,
The cost estimation unit designates parts necessary for cost estimation based on the parts table and requests the search processing unit to search for price information. The search processing unit first searches the actual price storage unit that holds the price information of the parts that have been purchased for the price information of the parts designated for retrieval, and searches the actual price storage unit for the parts that could not be searched. Independently searches the new price storage unit that holds the price information of the parts, and returns the search result to the cost estimation unit. The cost estimating unit estimates the cost of the product based on the retrieved price information and the bill of materials. At this time, for new parts for which price information has not been registered in either the actual price storage unit or the new price storage unit, price information cannot be obtained at this time, so that accurate estimation cannot be performed. Therefore, the user determines the price of the component by examining the material at hand or inquiring the component maker, and inputs the price from an input device such as a keyboard. In response, the new price input unit registers the component price information in the new price storage unit according to the user input. When such registration is performed, the price information of the above-mentioned parts registered in the new price storage unit is searched at the time of the subsequent estimate calculation based on the same parts table as described above or another parts table including newly registered parts. As a result, later estimation calculations can be performed with high accuracy. It should be noted that, when the above-mentioned new part which has not been registered in the actual price storage unit is actually purchased and a price based on the purchase result is registered in the actual price storage unit, the registered price is preferentially used. become.

If you register a search condition that gives priority to the storage unit, and register the latest price or near future price of parts such as semiconductor parts whose prices fluctuate rapidly in the new price storage unit as well as the price of new parts The cost is estimated by using the predicted price registered by the user in preference to the actual price.

[0012] A cost estimating apparatus according to a second invention comprises:
An actual price storage unit that holds price information on parts that have been purchased, a new price storage unit that holds price information on parts independently of the actual price storage unit for each of a plurality of scheduled purchase times, and a search condition. A search condition storage unit for storing, a search condition input unit for registering a search condition in the search condition storage unit according to an input from an input device, and a search condition registered in the search condition storage unit for storing the actual price storage unit. If the search conditions are prioritized, the actual price storage unit is first searched for the price information of the part designated to be searched, and for the parts for which price information cannot be obtained in the actual price storage unit, the new price storage unit is used. When the price information is searched, and the search condition registered in the search condition storage unit is a search condition giving priority to the new price storage unit, the price information of the part designated to be searched is Means for searching the new price storage unit, and searching for price information from the actual price storage unit for parts for which price information cannot be obtained in the new price storage unit.

This is a means for outputting to the device 5 and the printer 7.

FIG. 2 is a flowchart showing an operation example of the data processing device 1. Hereinafter, the operation of the data processing device 1 according to the present embodiment will be described with reference to FIGS.

When the user directly inputs a parts table for the designed apparatus from the input device 6 or requests the input by specifying a parts table stored in the file device 4, the parts table of the data processing apparatus 1 is input. The acquiring unit 12 reads the bill of materials and transmits it to the cost estimating unit 11 (Step S
1).

The cost estimating unit 11 first analyzes the parts table and selects parts necessary for cost estimation (step S2). Next, all the selected components are designated, a request is made to the search processor 2 for price information search, and the search result is received (step S3). The operation of the search processing device 2 for which the search has been requested will be described later. If the processing cost is also taken into account, the cost estimating unit 11 extracts the name of the device requiring the processing cost from the parts table, specifies it, and
In step 3, the search processing device 2 is requested to search for price information.

When the search result is returned, the cost estimating unit 11 checks whether all the price information necessary for the cost estimation has been searched (step S4). The cost of the product is estimated based on the price information and the input parts table (step S5), the estimated price is output to the display device 5 or the printer 7 (step S6), and the operation is completed.

On the other hand, when some price information necessary for cost estimation is not retrieved, the cost estimation unit 11 outputs a price unset message to the display device 5 specifying a part or the like for which price information was not obtained. To notify the user (step S7). Thereafter, in the present embodiment, the user waits for a selection from the user (step S8), and if the user selects an operation that does not newly input price information from the input device 6 (NO in step S8), the price information is searched. The prices of all parts and the like that have not been set are set to default values (for example, 0) (step S9), and the process proceeds to step S5 to perform cost estimation calculations. On the other hand, if the user selects new registration, the process returns to step S3 after the new price registration process (step S10) by the new price input unit 13, and requests the search processing device 2 to search for price information again. The request at this time may be all parts and the like necessary for cost estimation, or may be limited to only parts and the like that were not searched previously.

In the registration of the price information in step S10, the new price input section 13 registers the part name and the price information or the apparatus name and the processing cost thereof input by the user from the input device 6 in the new price storage section 32. Is performed. The registration of the new price by the new price input unit 13 can be performed not only during such estimation calculation but also at any time desired by the user.

FIG. 3 is a flowchart showing a processing example of the search processing unit 21 of the search processing device 2. Hereinafter, the operation of the search processing unit 21 will be described with reference to FIGS.

When the search is requested by the cost estimating unit 11, the search processing unit 21 receives the request (step S1).
1) The search conditions stored in the search condition storage unit 22 are read (step S12) and determined (step S1).
3). When the search condition includes a condition that the actual price is prioritized, the actual price storage unit 31 is set as the first storage unit, and the new price storage unit 32 is set as the second storage unit (step S14), and the process proceeds to the subsequent processing. Conversely, when the search condition includes a condition that gives priority to the new price, the new price storage unit 32 is set as the first storage unit, and the actual price storage unit 31 is set as the second storage unit (step S15), and the process proceeds to the subsequent processing. .

Steps S16 to S23 are first performed on the price information designated to be searched by the cost estimating unit 11.
This is a process of searching the storage unit and searching the second storage unit for price information for which price information cannot be obtained in the first storage unit. First, pay attention to one of the search targets (step S1).
6) Retrieve the price information from the first storage unit (step S18). If the search is successful, the set of the current search target and its price information is stored (step S20), and the process returns to step S16 to process the next search target. When the price information is not obtained by searching the first storage unit (step S
19 is NO), and the second storage unit is searched (step S2).
1) If the search is successful (YES in step S22),
Proceeding to step S20, the set of the current search target and its price information is stored, and the flow returns to step S16 to process the next search target. If the search also fails in the second storage unit (NO in step S22), the fact that the search of the current search target has failed is stored (step S23), and the process returns to step S16 to process the next search target. When the search processing for all requested search objects is completed (YE in step S17)
S), the search results stored so far are collectively returned to the cost estimating unit 11 (step S24).

Next, an example of the embodiment shown in FIG. 1 will be described.

(1) First Embodiment FIG. 4 shows an example of the contents of the actual price storage unit 31. In this example, the actual price storage unit 31 stores component price information 311 for each component with a purchase record and processing cost information 312 for each device with a record. The part price information 311 corresponding to one part includes information such as a part name, a unit price, a purchaser, a purchaser, and a purchase time. The processing cost information 312 corresponding to one device includes information such as a device name and a processing cost. The unit of the price is all yen.

FIG. 5 shows an example of the contents of the new price storage unit 32. Here, an example is shown in which new part price information 313 and new processing cost information 314 can be registered. One piece of new part price information 313 includes information such as a part name, a unit price, and a purchaser. Although there is no purchase record, there is a maker Z that supplies the part X, and when the user's investigation reveals that the price is Y, the part name, unit price, and purchase destination of the new part price information 313 are respectively X, Y, and Z are registered. In the case of a new apparatus, the user can examine the processing cost and register it as new processing cost information 314.

FIG. 6 shows an example of a parts list of a product for which cost estimation is to be performed. The parts table shows that the model M designed by the user is composed of two parts a, which are composed of one part a and two parts a, one apparatus A machined with two parts b, and a part 2
It shows that it is made up of two B devices which are machined with four c-parts consisting of three parts and three c-parts. Here, the device having the name of “device” is a device that requires a processing cost.

FIG. 7 is a diagram for explaining the operation of the present embodiment, and shows an operation example when a search condition giving priority to an actual price is registered. In the initial state, as shown in FIG. 7A, the actual price storage unit 31 has registered therein the component price information of the parts A and B, and the processing cost information of the apparatus A and the apparatus B, and stores the new price. No information is registered in the unit 32. In this state, when the parts table shown in FIG. 6 is acquired by the parts table acquisition unit 12, the following processing is performed.

The cost estimating unit 11 first analyzes the parts table shown in FIG. 6 to select parts a, b, c, and b as parts necessary for cost estimation, and processes necessary for cost estimation. The device A and the device B are selected as the expensive devices (step S2). Next, all the selected parts and the like are designated, and a search for price information is requested to the search processing unit 21 (step S3).

When the search processing unit 21 receives the above search request from the cost estimation unit 11 (step S11),
The search condition stored in the search condition storage unit 22 is read (step S12). In this case, the actual price is a search condition that gives priority to the actual price, so the actual price storage unit 31 is the first storage unit, and the new price storage unit 32 is the second storage unit. (Step S14).
Then, the price information is first stored in the actual price storage unit 3 for each search target designated to be searched by the cost estimation unit 11.
1 and the actual price storage unit 31 for which price information cannot be obtained is searched from the new price storage unit 32. FIG. 7B shows the search result at this time.

When the search result shown in FIG. 7B is returned, the cost estimating unit 11 checks whether all the price information necessary for cost estimation has been searched (step S4). Since the price information of the parts and b parts was not retrieved, a price unset message designating the parts c and b for which the price information was not obtained is output to the display device 5 and notified to the user (step S7). Wait for the selection of the next operation from (step S8).

At this time, the user investigates the component price, and from the input device 6, the c component as shown in FIG.
Assuming that the price information of the part is registered in the new price storage unit 32 through the new price input unit 13, the content of the new price storage unit 32 is changed at that time as shown by a broken line in FIG. Therefore, when the cost estimating unit 11 returns to step S3 and requests the search processing device 2 to perform a re-search, the price information of the c component and the b component that were not searched previously can be obtained. The cost estimating unit 11 calculates and outputs the cost of the model M from the price information and the bill of materials (Step S).
5, S6). FIG. 7D shows a calculation example of the cost estimate at this time.

The user evaluates the output estimated price, and if the price is not satisfactory, changes the design. Due to the design change of the model M, the parts list is also changed. When the user inputs the changed parts list and performs the cost estimation again, even if the parts table and the parts b exist in the parts table, their price information is already registered in the new price storage unit 32. You do not need to enter it again. The same applies to a case where another user inputs a parts table including parts c and b.

As described above, according to the present embodiment, the price investigated by the user for a part for which the price has not been registered can be effectively used for the later estimation calculation.

In the above operation example, the new price storage unit 32 is used only for parts that are not registered in the actual price storage unit 31.
The price information is registered in the actual price storage unit 31. However, the price information of the parts already registered in the actual price storage unit 31 may be registered in the new price storage unit 32. Fig. 8 shows an example.
Shown in

In FIG. 8A, the parts registered in the actual price storage unit 31 are also registered in the new price storage unit 32. The advantage of performing such registration is that, when the component is a component whose price fluctuates greatly such as a semiconductor component and the actual price does not match the current situation, the user checks the latest price in the market and stores it in the new price storage unit 32. By registering and executing a search with a new price priority, a cost estimate can be made by using a predicted price registered by a user preferentially over an actual price. FIG. 8B shows an example of a search result of the search processing unit 21 when the search condition stored in the search condition storage unit 22 is changed to the new price priority and the parts table of FIG. 6 is input.
Since the new price storage unit 32 is searched first, the price of the component is 80, unlike FIG. Therefore, the estimated cost is as shown in FIG.

In the case of estimating based on prices at a certain point in the future such as six months later, all parts whose future prices of parts necessary for cost estimation differ from the actual prices stored in the actual price storage unit 31 , The predicted price is registered in the new price storage unit 32. In this case, if the search condition in the search condition storage unit 22 is set to the new price priority and operated, the cost can be estimated by using the predicted future price registered by the user preferentially over the actual price. Becomes

(2) Second Embodiment FIG. 9 shows an example of the contents of the actual price storage unit 31. This example
In the part price information 311 corresponding to one part name, the unit price,
A plurality of sets of information such as a purchaser, a purchaser, and a purchase time are registered, and processing cost information 3 corresponding to one device name is registered.
12 is different from the example of FIG. 4 in that a plurality of sets of information such as processing cost and processing time are registered.

FIG. 10 shows an example of the contents of the new price storage unit 32. In this example, in the new part price information 313 corresponding to one part name, a plurality of sets of information such as unit price, purchaser, and purchase time can be registered, and new processing cost information 314 corresponding to one apparatus name can be registered. It differs from the example of FIG. 5 in that a plurality of sets of information such as processing cost and processing time can be registered.

In this embodiment, as shown in FIGS. 9 and 10, the unit price and processing cost at different times are stored in the actual price storage unit 31.
In order to register the new price in the new price storage unit 32, a time condition is given at the time of the search, so that an estimate can be made using the unit price and processing cost desired by the user.

For example, if the use of “latest price” is registered in the search condition storage unit 22 through the search condition input unit 14 as a condition for searching the actual price storage unit 31, the search processing unit 21 Retrieves the latest price recorded in the part price information 311 and the processing cost information 312 when searching the actual price storage unit 31 in step S18 or step S21 in FIG. The other search conditions may be specified by specifying a specific time, searching for price information at a time closest to the specified time, or specifying an average, and obtaining part price information 311 or processing cost. For example, the average of all prices recorded in the information 312 may be obtained.

Similarly, as a condition for searching the new price storage unit 31, for example, “6 months ahead price” is registered as a search condition in the search condition storage unit 22 through the search condition input unit 14. The processing unit 21 performs step S in FIG.
18 or in step S21, the new price storage unit 32
Is retrieved, price information closest to the designated time is extracted from the plurality of pieces of price information recorded in the new part price information 313 and the new processing cost information 314. According to such a configuration, it is possible to estimate the cost at each future time. As another method of giving the search condition, there is a method of designating that an average is to be obtained, and obtaining an average value of all prices recorded in the new part price information 313 and the new machining cost information 314.

The above-mentioned temporal search conditions are registered in the search condition storage unit 22 in combination with the search conditions of the actual price priority and the new price priority.

[0054]

As shown in FIG. 11, the search condition input unit 14 and the search condition storage unit 22 are omitted from the configuration of FIG. 1, and the cost estimation is performed from the input device 6 or the file device 4 instead of the parts table acquisition unit 12. A parts list / search condition obtaining unit 12 ′ that obtains a parts list and search conditions of a target product and transmits the obtained information to the cost estimating unit 11 may be provided. In this case, in step S3 of FIG. 2, the cost estimation unit 11 specifies parts and search conditions necessary for cost estimation based on the parts table and the search conditions acquired by the parts table / search condition acquisition unit 12 '. The search processor 21 requests the search processor 21 to search for price information, and the search processor 21 reads the search conditions sent from the cost estimator 11 in step S12 in FIG.

FIG. 12 is a configuration diagram of still another embodiment of the present invention. As shown in the figure, in the present embodiment, a plurality of first computers C1 each realizing the data processing device 1 of FIG. 1 or FIG. 11 and a search processing device 2 of FIG. 1 or FIG. 11 are realized. One computer C2 is communicably connected via a communication path P, and a second computer C2 is connected.
2 shows a storage device M similar to the storage device 3 of FIG. 1 or FIG.
Are connected. Here, K1 in FIG.
Is a machine-readable recording medium such as a magnetic disk device, a semiconductor memory, and a CD-ROM for storing the first program. The first program stored in the recording medium K1 is read by the first computer C1. By controlling the operation of the first computer C1, the cost estimating unit 11, the parts list obtaining unit 12, the new price input unit 13 and the search condition input unit 14 of FIG. A cost estimation unit 11, a parts table / search condition acquisition unit 12 ', and a new price input unit 13. K2 is a machine-readable recording medium such as a magnetic disk device, a semiconductor memory, and a CD-ROM for storing the second program. The second program stored in the recording medium K2 is stored in the second computer C2. By controlling the operation of the second computer C2, the search condition storage unit 22 and the search processing unit 21 of FIG. 1 or the search processing unit 21 of FIG. 11 are realized on the second computer C2. In this case, the search condition input unit 1
4 accesses the new price storage unit 32 in the storage device M via the second computer C2.

[0057]

As described above, according to the present invention, the following effects can be obtained.

According to the first and second aspects of the present invention, the price of a part for which a price has not been registered by a user can be effectively used for a later estimate calculation.
The reason is that a new price input unit is provided for registering the price investigated by the user in the new price storage unit, and the search processing unit searches the new price storage unit for parts for which there is no price information in the actual price storage unit. As a result, the unit price of a component investigated by a certain user can be used for subsequent cost estimation of the same user or another user, and it is possible to improve estimation accuracy and avoid duplicate surveys.

In the first and second inventions, the cost can be estimated by using the predicted price registered by the user preferentially over the actual price. The reason is that when a search condition that gives priority to the new price storage unit is used, the search processing unit searches the new price storage unit with higher priority than the actual price storage unit. For this reason, for a component whose price fluctuates greatly, such as a semiconductor component, its estimated price is registered in the new price storage unit as in the case of the new component, so that the estimate at the design stage is actually used.
The price can be set based on the price at a point in time, such as six months or six months in advance.

In the second invention, cost estimation can be performed based on prices at different times in the future.
