Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a product evaluation program for determining whether a product is made up of parts that satisfy a predetermined standard.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, when a certain product is manufactured, parts constituting the product have been designed by a designer of the product based on the performance of the product and the performance of a specific portion. Also, considering the cost of products, individual electronic components used in electronic devices and the like have low unit prices and high quality. Therefore, in order to procure such electronic components, the designer of the device in charge designs and designs various electronic components in consideration of cost reduction of the product, purchases and assembles various electronic components specified there.
[0003]
However, in many cases, similar products or circuits composed of a plurality of parts before the products are produced at different production sites. Therefore, since most of the electronic components used are the same or similar electronic components, the cost reduction in component procurement is not limited to individual production sites or individual design departments, but should be made company-wide.
[0004]
Therefore, in the procurement of electronic components, a component purchase evaluation program that provides information on cost reductions throughout the company in order to reduce the unit cost of components has been considered (for example, see Patent Document 1).
[0005]
As shown in FIG. 15, the parts purchase evaluation program uses the parts information database 2 and the purchase results data 1 in accordance with a purchase request input including a desired specification and a desired purchase quantity of a desired part. Setting a permissible range of the desired specification for the desired specification included in the purchase request input, and extracting a part name having an actual specification existing within the permissible range of the desired specification from the part information database 2 as a purchase proposal part; The purchase quantity and purchase unit price of the already purchased parts having the actual specifications existing within the permissible range are extracted from the purchase result data 1, the purchase proposal part purchase price is calculated, and the purchase price and the purchase proposal part purchase are calculated. It is to compare with the amount.

[0007]
[Problems to be solved by the invention]
However, the above-mentioned conventional evaluation program evaluates individual components of a product and does not take into account information related to a final product. As a result, the cost of using over-spec components is consequently reduced. There was a problem that the height could not be prevented.
[0008]
In addition, the above evaluation program focuses on the purchase price of each part, and it is not possible to deal with differences in evaluation criteria depending on the product, such as emphasizing the performance of specific parts even if the price is slightly higher. was there.
[0009]
Therefore, an object of the present invention is to provide a product evaluation program capable of determining whether or not a product concerned is constituted by parts satisfying a predetermined criterion based on an evaluation criterion for each product.
[0010]
[Means for Solving the Problems]
In order to solve the above problem, the present invention prepares product type component evaluation information (electronic component evaluation DB) in which each component in a product type is evaluated, and stores the product type information of the product and the component information constituting the product. The method is characterized in that an evaluation value of each component constituting the product is obtained by inputting and evaluating the component in the product type of the product type component evaluation information, and the evaluation value of the product is calculated.
[0011]
As a result, since the product evaluation value is calculated based on the evaluation of the parts in the product type, the product can be evaluated in accordance with the difference in the evaluation of the parts due to the difference in the product type. Can be performed.
[0012]
Further, the present invention is characterized in that the number of parts to be used is input together with the parts constituting the product, and an average value of evaluation values per part in the product components is calculated as the evaluation value of the product. It is assumed that.
[0013]
As a result, since the sum of the evaluation values of all parts is divided by the quantity of all parts to obtain the product evaluation value, the evaluation value for each component can be compared as the evaluation value of the product. Regardless of the number of parts, the same comparison can be performed for all products.
[0014]
Furthermore, the present invention allows the user to input a changed part for changing the component configuration of the product and changing it to a substitute part, and to input a replacement part to be a part constituting the product instead of the changed part, The evaluation value of the product is recalculated based on the calculated value.
[0015]
As a result, the product evaluation value is recalculated with the component configuration changed to the substitute part. Therefore, even when the evaluation value of the product does not reach the product evaluation standard value, the component parts are changed and the product evaluation value is easily recalculated. It can be calculated, and the components of the product can be considered until the product evaluation standard value is satisfied.
[0016]
Further, the present invention is characterized in that a component whose evaluation value in the product type of the input component is less than the product evaluation reference value is displayed, and the changed component is input.
[0017]
As a result, a part whose evaluation value is less than the product evaluation reference value can be displayed as a candidate for a changed part, so that a part whose product evaluation reference value is lowered can be selected and set as a change target part. It is possible to easily increase the product evaluation value due to the part change.
[0018]
Further, the present invention is characterized in that the parts are displayed in ascending order of the evaluation value in the product type of the inputted parts, and the changed parts are inputted.
[0019]
As a result, parts can be displayed in the order of lower evaluation values as candidates for changed parts, so that parts having lower evaluation values can be considered as parts to be changed, and a rise in the product evaluation value due to the part change can be quickly increased. It can be easily performed.
[0020]
Further, according to the present invention, component group information (substitute electronic component DB 117) is prepared by grouping components that can be replaced with each other, and components in the same group as the input changed component are displayed as substitute component candidates. And inputting the substitute part.
[0021]
As a result, a part that can be replaced with the changed part is displayed as a candidate for the replacement part, so that the candidate for the replacement part can be easily selected, and the design of the part configuration that satisfies the product reference value can be easily performed. It becomes.
[0022]
Further, the present invention provides a product type weighting information (product type weighting DB 113) in which evaluation items are weighted for each product type, and a component evaluation information (electronic component PB information DB 111) in which the evaluation items are evaluated for each component. ) Is prepared, and the product type component evaluation information (electronic component evaluation DB 115) is created according to the product type weighting information and the component evaluation information.
[0023]
Thus, the product type component evaluation information is created based on the product type weighting information having the information on the evaluation items and the component evaluation information having the component information, so that it is easy to add a component or change the importance of each evaluation item. And can respond to the emergence of new products and changes in policies.
[0024]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0025]
FIG. 1 shows a configuration diagram of a product evaluation system according to the present invention. As shown in FIG. 1, the product evaluation system 101 is connected to a user terminal 123 via a network 121, and receives information from the user terminal 123 and transmits information to the user terminal 123 through a network. 121 is made possible.
[0026]
The product evaluation system 101 includes a program storage unit 109, an electronic component private information DB 111, a product type weighting DB 113, an electronic component evaluation DB 115, an alternative electronic component DB 117, and a parts table file 119.
[0027]
Further, the program storage unit 109 stores the electronic component evaluation program 103, the product evaluation program 105, and the alternative electronic component selection program 107.
[0028]
The electronic component evaluation program 103 creates an electronic component evaluation DB 115 from the electronic component private information DB 111 and the product type weighting DB 113.
[0029]
The product evaluation program 105 searches the electronic component evaluation DB 115 based on the component table file 119, and evaluates whether a combination of components constituting a product satisfies a predetermined standard.
[0030]
The alternative electronic component selection program 107 is called as a subroutine of the product evaluation program 105, and uses the alternative electronic component DB 117 to select an alternative electronic component.
[0031]
The electronic component private information DB 111 evaluates the evaluation items for each component, and evaluates all the evaluation items (five-level evaluation) for each component model number.
[0032]
The product-type weighting DB 113 weights each of the same evaluation items as the electronic component private information DB 111 for each product type, and assigns the evaluation ratio (percentage:%) for each product type. Things.
[0033]
The electronic component evaluation DB 115 evaluates each component in the product type for each product type, and attaches an evaluation score for each product type and component model number. As described above, the electronic component evaluation DB 115 is created by the electronic component evaluation program 103 in accordance with the electronic component private information DB 11 and the product type weighting DB 113.
[0034]
The replacement electronic component DB 117 groups components that can be replaced by each other, and assigns a group number to each component model number.
[0035]
The parts table file 119 is created for each product to be evaluated, and includes a product type, a part number, an amount of the part used in the product, and an electronic part flag indicating whether the part is an electronic part. It is what you have.
[0036]
The parts table file 119 is created when a user (for example, a designer of a product) inputs, from the user terminal 123, product type information of a product to be evaluated and information of parts constituting the product. .
[0037]
Here, the part information is a part model number of the product and a quantity of the part used. Further, the electronic component flag of this component may be made to be input by the user, or the user simply inputs the model number of the component constituting the product, and the electronic component flag is stored in the electronic component private information DB 111. The electronic component may be set to stand alone, or an integrated component DB may be separately provided and an electronic component flag may be provided therein.
[0038]
In the product evaluation system 101, a process of preparing the electronic component evaluation DB 115, which is a preparation process for product evaluation, will be described with reference to a flowchart shown in FIG.
[0039]
As described above, the electronic component evaluation DB 115 is created by the electronic component evaluation program 103. The electronic component evaluation program 103 is executed when a new component is registered in the electronic component private information DB 111, or when a new product is developed and a new product type is added to the product type weighting DB 113, A new product type and component model number are added to the electronic component evaluation DB 115, and an evaluation score is calculated.
[0040]
As shown in FIG. 2, when the electronic component evaluation program 103 is executed, first, the product type weighting DB 113 is sequentially read (s201).
[0041]
Here, FIG. 3 shows a data structure diagram of the product type weighting DB 113. As shown in the figure, the product type weighting DB 113 stores a plurality of evaluation items for each product type, in this case, unit price evaluation, use results, supplyability evaluation, reliability evaluation, test results, manufacturability evaluation, and market quality. Weighting is performed for each of the seven items, and the evaluation ratio is expressed as a percentage (%) for each product type.
[0042]
The difference in the weighting is, for example, in “Home Audio”, since the indoor use is large, the unit price evaluation and the use result are important. However, in “Mobile Phone”, from the cold region such as Hokkaido in the middle of winter, the desert, This is because the importance of evaluation items differs depending on the product, for example, reliability is important because there is a large difference in the use environment such as in a tropical region.
[0043]
Returning to the flowchart of the creation processing of the electronic component evaluation DB 115, when the weight DB for each product type is read (s201), it is determined whether or not there is a record (s203). The product-type weighting DB 113 is read to the end, and when there are no more records, the process of creating the electronic component evaluation DB 115 ends. If there is a record of the product type weighting DB 113, the electronic component private information DB 111 is sequentially read (s205).
[0044]
Here, FIG. 4 shows a data structure diagram of the electronic component private information DB 111. As shown in the figure, the electronic component private information DB 111 sets the same evaluation item, unit price evaluation, usage record, supplyability evaluation, reliability evaluation, test result, and evaluation item of the product type weighting DB 113 for each part model number. The evaluation was performed for each of the seven items of sex evaluation and market quality, and each evaluation was expressed in five stages (1 to 5) for each part model number.
[0045]
In this evaluation, each part was evaluated in five stages for each evaluation item of unit price evaluation, use performance, supplyability evaluation, reliability evaluation, test results, manufacturability evaluation, and market quality. "5" is the highest rating and "1" is the lowest rating.
[0046]
Further, the electronic component private information DB 111 is a large file that has a data number of about 400,000 and covers about 300 new additions per month in order to cover all electronic parts.
[0047]
Returning to the flowchart of the creation process of the electronic component evaluation DB 115, when the electronic component private information DB 111 is read (s205), it is determined whether or not there is a record (s207). The electronic component private information DB 111 is read to the end, and when there are no more records, the process returns to the reading process (s201) of the product type weighting DB 113, and the same process is repeated for the next record of the product type weighting DB 113.
[0048]
If there is a record in the electronic component private information DB 111, the weight of each evaluation item in the corresponding product type in the product type weighting DB 113 is applied to the value of each evaluation item in the corresponding component in the electronic component private information DB 111, and The total evaluation score of the part model number in the product type is calculated (s209).
[0049]
The calculation formula is obtained by dividing the evaluation value of the electronic component private information DB 111 by “5 (the number of evaluation steps)” and multiplying the result by the weight of the product type weighting DB 113 for all the evaluation items, and summing them. . For example, the total evaluation score of the part number “CN1001” in the product type “Home Audio” is:
[0050]
2/5 * 20 + 3/5 * 20 + 2/5 * 10 + 5/5 * 15 + 5/5 * 15 + 4/5 * 10 + 5/5 * 10 = 72.0
Is calculated.
[0051]
Next, in the electronic component evaluation DB 115, a record of the corresponding component model number of the electronic component private information DB 111 is created with the corresponding product type of the product type weighting DB 113, and the calculated total evaluation score is set (s211).
[0052]
Here, FIG. 5 shows a data structure diagram of the electronic component evaluation DB 115. As shown in the figure, the electronic component evaluation DB 115 has a comprehensive evaluation score for each product type and component model number, and creates data of all combinations of product types and component model numbers.
[0053]
Returning to the creation flowchart of the electronic component evaluation DB 115, after setting the total evaluation score in the electronic component evaluation DB 115 (s211), the electronic component private information DB 111 is read again (s205). Then, the above process is repeated for all the component model numbers in the electronic component private information DB 111, and further, the above process is repeated for all the product types in the product type weighting DB 113, and the total evaluation score of the combination of all the product types and component model numbers is calculated. Ask.
[0054]
Through the above processing, the electronic component evaluation DB 115 is created. With this process, preparations for product evaluation were completed.
[0055]
The process of creating the electronic component evaluation DB 115 may be performed in the product evaluation program 105, or the electronic component evaluation DB 115 may be created without using the electronic component private information DB 111 and the product type weighting DB 113 as needed. The score may be calculated. However, as described above, the processing speed slows down and the load increases due to a problem such as a large number of data in the electronic component private information DB 111. Therefore, it is preferable to create the electronic component evaluation DB 115 in advance.
[0056]
Further, only the electronic component evaluation DB 115 may be created without creating the electronic component private information DB 111 and the product type weighting DB 113. However, the situation where the electronic component private information DB 111 and the product type weighting DB 113 are provided, It is easy to respond to changes. For example, with the electronic component private information DB 111, it is possible to respond to addition or deletion of components or change of each evaluation item at any time. Further, if there is a weight DB for each product type, it is easy to cope with a change in weight for each evaluation item or addition of a product (product type). In particular, since the weighting for each evaluation item greatly depends on the company or the trend of the times (fashion), it is better to have a file that can be changed at any time.
[0057]
Next, the operation process of the product evaluation program 105 will be described with reference to a flowchart shown in FIG.
[0058]
When the product evaluation program 105 is executed, first, the total score and the total quantity are set to zero, and the area used for calculation is cleared (s301). Next, the data of the product to be evaluated is read from the parts table file 119 (s303).
[0059]
Here, FIG. 7 shows a data structure diagram of the parts table file 119. As shown in the figure, the parts table file 119a is composed of a record having the product type to be evaluated and the part model numbers of all the registered components constituting the product. In addition to the product type and part model numbers, The electronic component has an electronic component flag indicating the quantity of the component used in the product and whether or not the component is an electronic component.
[0060]
Also, as described above, the parts table file 119 allows the user (for example, the designer of the product) to input, from the user terminal 123, the product type information of the product to be evaluated and the component information constituting the product. Is created by
[0061]
Further, in the present embodiment, the product evaluation program 105 is executed by using the parts table file 119. However, the user does not create the parts table file 119, and the user individually inputs the product type information and the product type information during the product evaluation. Component information may be input.
[0062]
Returning to the flowchart of the operation process of the product evaluation program 105, when the parts table file 119 is read (s303), it is determined whether there is a corresponding record (s305). The corresponding record in the parts table file 119 is read to the end, and when there are no more records, an evaluation score calculation process (s315) described later is performed.
[0063]
If there is a corresponding record in the parts table file 119, it is determined whether or not the part is an electronic part based on the electronic part flag (s307). If it is not an electronic component, the process returns to the reading process of the parts table file 119 (s303), and the same processing is repeated for the next applicable record of the parts table file 119.
[0064]
If it is an electronic component, the electronic component evaluation DB 115 is searched using the product type and the component model number, and a comprehensive evaluation score is obtained (309).
[0065]
Next, the total score obtained by multiplying the obtained total evaluation score by the quantity of the part model number is added (s311). Subsequently, the quantity of this part model number is added to the total quantity (s313). If the numerical values can be stored in the total score and the total amount, the process returns to the reading processing of the parts table file 119 (s303), and the same processing is repeated for the next applicable record in the parts table file 119.
[0066]
When the calculation for all applicable records in the parts table file 119 is completed and there are no more applicable records (determined in s305), an evaluation score calculation process (s315) is performed. In the evaluation score calculation process, the total score calculated in the above process divided by the total amount is calculated as the evaluation score of this product.
[0067]
Here, FIG. 8 shows a product evaluation result based on the component configuration shown in the component table file 119a. In this “Home Audio”, the electronic components are “CN1001” and “CN1002”, and the quantities are “3” and “2”, respectively. The total evaluation score of “CN1001” is “72.0”, and “CN1002” is “80.0”. Therefore, as shown in the figure, the total score is “376.0”, the total quantity is “5”, and the product evaluation score of the product in this component configuration is “75.2”.
[0068]
After the evaluation score is calculated, it is determined whether or not the evaluation score has reached the reference value (s317). If the evaluation score has reached the reference value, the present product evaluation processing is terminated. If not, the alternative electronic component selection processing (s319) replaces the electronic parts constituting this product. Is performed, the total score and the total amount are set to zero (s301), and the evaluation score is calculated again.
[0069]
By the above processing, the target product can be evaluated, it can be easily determined whether or not the product is configured by components that satisfy a predetermined standard, and when the standard is not satisfied, a substitute component is determined. It can be specified and re-evaluated.
[0070]
Next, the alternative electronic component selection processing will be described with reference to a flowchart shown in FIG.
[0071]
When the alternative electronic component selection process is designated in the product evaluation program 105, the alternative electronic component selection program 107 is started, and the alternative electronic component selection process is performed. In the alternative electronic component selection process, components having evaluation scores equal to or less than a reference value are displayed on the list screen in descending order of the total evaluation score as change candidate components to be changed from the designated components to alternative electronic components (s401).
[0072]
FIG. 10 shows an example of an evaluation score display screen of the change candidate part. As described above, the evaluation score display screen displays a list of component model numbers whose evaluation scores are equal to or smaller than the reference value in ascending order of the total evaluation score. In addition, the total evaluation score is described together with the part model number. Further, a "change" button is provided for each of the part model numbers so that the part model number to be changed can be selected. The “edit end” button at the bottom is selected when all the change processing is completed.
[0073]
From the part evaluation score display screen, select a part model number to be changed to a substitute part, and click a "change" button on the right side of the part model number. When all the changes have been completed, the user clicks on the “edit end” button.
[0074]
In the alternative electronic component selection process, after displaying the component evaluation score (s401), it is determined whether or not the editing is completed (s402). If the editing is completed, the alternative electronic component selection process is completed.
[0075]
If the editing has not been completed, the part model number to be changed is selected (s403), the alternative electronic component DB 117 is searched with this part model number, and a group number is obtained (s404).
[0076]
Here, FIG. 11 shows a data structure diagram of the substitute electronic component DB 117. As shown in the drawing, the substitute electronic component DB 117 has items of a component model number and a group number, and groups the components that can be replaced with each other. Is what is shaken.
[0077]
Returning to the flowchart of the alternative electronic component selection process, when the group number of the changed component model number is obtained (s404), a component model number having the same group number as the obtained group number is searched from the alternative electronic component DB 117. Further, the electronic component evaluation DB 115 is searched based on the part model number searched by the above search and the product type of the parts table file 119, and an overall evaluation score is obtained (s405).
[0078]
Next, the retrieved part model numbers are displayed as a list on the alternative parts list screen (s406). At this time, the obtained total evaluation score of each part model number is also displayed together with the part model number.
[0079]
FIG. 12 shows a screen example of the substitute part list. This alternative part list screen example shows a screen example when the part model number “CN1001” is selected in the evaluation score display screen example of the change candidate part.
[0080]
On the alternative parts list screen, as described above, a list of parts model numbers whose groups match the part model number “CN1001” whose change is specified is displayed. In addition, the total evaluation score is described together with the part model number. Further, a selection button is provided for each of the component model numbers so that a component model number as a substitute component can be selected. The “OK” button at the bottom is selected when the selection processing is completed, and the “Cancel” button is selected when the processing is canceled and the display returns to the component evaluation score display screen.
[0081]
From the replacement parts list screen, select a part model number to be designated as a replacement part and click an "OK" button at the bottom.
[0082]
In the alternative electronic component selection process, when the alternative component list screen is displayed (s406), the user selects an alternative component from the alternative component list screen (s407). Next, the part model number instructed to be changed in the parts table file 119 is replaced with the part model number of the selected alternative electronic component, the display returns to the evaluation score display screen, and the editing end is determined (s402).
[0083]
Here, FIG. 13 shows a data structure diagram of the parts table file 119 changed by the substitute electronic component. As shown in the figure, in the parts table file 119b, the parts model number “CN1001” is changed to “CN1003” in the parts table file 119a.
[0084]
In the above-described product evaluation process, the replacement of the electronic component is performed as described above, and the product is reevaluated with the replaced component configuration.
[0085]
FIG. 14 shows a product evaluation result of a product composed of components of the component table file 119b in which the component model number “CN1001” is replaced with “CN1003”. As shown in the figure, the total score has been changed from "376.0" to "406.0" and the product evaluation score has been changed from "75.2" to "81.2". I was able to exceed.
[0086]
By the above processing, even if the designed component configuration does not satisfy the product reference value, the electronic component to be changed from the previous component configuration is selected, and an alternative electronic component to replace this component is selected. It can be easily changed to a component configuration that satisfies the reference value.

【The invention's effect】
According to the present invention, component evaluation information of each product type in which each component is evaluated in the product type is prepared, and evaluation values of each component constituting the product are obtained by evaluating the components in the product type, and the evaluation value of the product is calculated Therefore, it is possible to evaluate a product corresponding to a difference in component evaluation due to a difference in product type, and it is possible to perform an evaluation in consideration of characteristics of each product type.
[0099]
Further, according to the present invention, since the average value of the evaluation values per component in the product component is calculated as the evaluation value of the product, the evaluation value per component is compared as the evaluation value of the product. The same comparison can be performed for all products regardless of the number of component parts.
[0100]
Further, according to the present invention, the part configuration of the product is changed and a changed part to be changed to a substitute part is input, and a substitute part which is a part constituting the product is input instead of the changed part. Since the evaluation value of the product is recalculated based on the parts, even when the evaluation value of the product does not satisfy the product evaluation reference value, it is possible to easily recalculate the product evaluation value by changing the constituent parts. The components of the product can be considered until the product evaluation standard value is satisfied.
[0101]
Further, according to the present invention, a part whose evaluation value in the product type of the input part is less than the product evaluation reference value is displayed, and the changed part is input, so that the product evaluation reference value is lowered. A part can be selected to be a part to be changed, and the product evaluation value can be easily increased by changing the part.
[0102]
Further, according to the present invention, the parts are displayed in ascending order of the evaluation value in the product type of the inputted parts, and the changed parts are input, so that the parts having the lower evaluation values are considered as the parts to be changed. This makes it possible to quickly and easily increase the product evaluation value due to the change of parts.
[0103]
Further, according to the present invention, component group information in which components that can be replaced by the components are grouped is prepared, and components in the same group as the input changed component are displayed as replacement component candidates, and the replacement component is displayed. Is input, it is possible to easily select a candidate for a substitute part, and to easily design a component configuration that satisfies the product reference value.
[0104]
Furthermore, according to the present invention, the product type component evaluation information is calculated according to the product type weighting information obtained by weighting the evaluation items for each product type and the component evaluation information obtained by evaluating the evaluation item for each component. Since it is created, it is possible to easily reflect the addition of parts or the change in importance for each evaluation item, and it is possible to respond to the emergence of a new product or a change in policy.
