[0005] Some pre-evaluation method is required to produce the product in the design stage, and it is necessary to perform an improved design based on the evaluation index obtained by the evaluation method.

[0006] For this purpose, several prior evaluation methods have been published as described above, but many of the evaluation methods published so far are: The evaluation index required at the checklist stage is qualitative and cannot be quantitatively evaluated.

(2) Evaluation requires abundant experience and knowledge.

(3) It is difficult to judge whether the design is good or bad only by the time or cost required for the obtained information for work and processing.

(4) The evaluation cannot be performed unless the design is completed or nears the end, and it is difficult to improve the design after the evaluation is completed.

(5) Only the easiness of work and processing is determined, and it is difficult to improve the design after evaluation.

This is used to derive detailed contents of work and processing on the article or part.

For the work and process contents derived by the database, a basic index indicating the difficulty of each work and process is given. The basic indicators are the time or cost of each task and process, these indices,
And it is determined based on a function or a function expression to be compared with these. Basic indicators are determined based on the environmental conditions of work and processing (same work and number of work, same work and processing procedure,

As one embodiment of the present invention, a method for evaluating the decomposition of an article will be described.

FIG. 2 shows the basic flow of the design and evaluation calculation of an article or part. In the concept design 11, a concept design of an article or a part is performed. At this stage, evaluation elements such as basic elements are extracted from the concept design drawing or the actual product or part at the evaluation element extraction 12, and the evaluation elements are input to the computer system equipped with the evaluation program at the evaluation element input 13. The input data can be stored in the external storage device 14. The automatic calculation 15 exchanges information with the storage device 16 storing the evaluation information to perform the automatic calculation, and the evaluation result output 17 outputs the evaluation result and the display of the improved case. Based on this, the necessity of design improvement is determined in the evaluation result determination 18, and when design improvement is necessary, design improvement is performed in design improvement 19, and effective improvement examples are added to the improvement case information. . When the design improvement is completed, the process proceeds to the detailed design 20. Note that after proceeding to the detailed design 20, the evaluation element extraction 12, the evaluation element input 13,

FIG. 3 shows a computer system equipped with an evaluation program according to the present invention. The hardware of this computer system stores an input device such as a pen input board 21 for inputting an evaluation element, a keyboard 22 or a mouse 23, a calculation device 24 for performing calculations, an evaluation program and basic data, input data and calculation results. A storage device 16, a printer 25 and a display 26 for displaying calculation results, and an external storage device 1 for storing evaluation results
4 and so on.

The configuration of software mounted on this hardware is as follows. First, as basic data to be stored in the storage device 16, a basic element (decomposing operation) X described with reference to FIG. 4, a deduction point εx as a basic index, and names, symbols, numerical values, and the like given to them are shown in FIG. The correction factors Y and Yn to be described and the correction coefficient α as a correction index, and the names, symbols, and numerical values, etc. given to the correction factors Y and Yn, and further, each processing of the evaluation process described with reference to FIG.

An example of the contents of the basic element X that classifies the disassembly operation of FIG. 4 is shown. Example 1 is a move up. The following is omitted,
These basic elements X can be extracted from information, articles, and parts described in the design drawing in which a predetermined disassembly operation is defined, and the disassembly operation is taken as the basic element X as in this example.

In the first column of FIG. 4, the name of the basic element X is described. The number of basic elements X can be large. The larger the number of basic elements, the higher the accuracy, but the more difficult it is to use. On the contrary, the smaller the number, the easier the evaluation process but the worse the accuracy. Assembly, not only for disassembly
In the case of processing, about 20 is actually the best.

In the second column of FIG. 4, a symbol corresponding to each basic element X is described. Here, the symbol is determined, for example, as "基本" for upward movement or "→" for lateral movement so as to easily associate the corresponding basic element X therewith. FIG.
In the third column, the basic deduction εx assigned to each basic element X
The example of the value of is described. In this embodiment, the upward movement “↑” which is most easily decomposed is taken as the “reference element Xo”, and the reference deduction εxo (X of the basic deduction εx) as the reference index A given thereto is taken.
Is set to 0), and as the other basic elements X become more difficult to be decomposed than the “reference element Xo”, the “decomposition number and decomposition means, for example, the conditions of the decomposition equipment used, that is, the decomposition environment conditions” As the disassembly cost Cx of each basic element X as shown in the fourth column becomes larger than the disassembly cost Cxo of the reference element Xo, the basic deduction εx
Is greater than 0, ie,

[0051]

(Equation 1)

Has been determined in advance. Where (Equation 1) a
1, a2 are constants and have a relationship of a1 = a2Cxo.

As an embodiment different from this embodiment, a decomposition time Tx and their indices Ix can be taken instead of the decomposition cost Cx. Further, the expression of the basic deduction εx includes the following (Equations 2 to 4) in which the increase / decrease tendency of εx with respect to the increase of Cx is different.

[0054]

(Equation 2)

[0055]

(Equation 3)

[0056]

(Equation 4)

Also, instead of the basic deduction εx, the basic coefficient ε′x
And the following (Equation 5, 6) or the like that is larger or smaller than a predetermined value (Example 1) may be used.

[0058]

(Equation 5)

[0059]

(Equation 6)

However, in (Equations 2 to 4), a3, a
4, a5, b1, b2, c1, c2, d1, d2, and β are constants. By appropriately selecting these constants, it is possible to change the tendency of the basic index to increase or decrease as the cost of the basic element or the required time increases.

FIG. 5 shows an example of the correction element Y. Correction element Y
Examples include the material m and the size l of the component, and a number of other types are also conceivable.

For each of these correction elements (m, l,...), A relatively simple one is selected to define a correction reference (mo, lo,...), And one state of each correction element is set. Or, it is divided into a plurality of n items, which can be specified by extracting from information, articles, and parts shown in the design drawings, and are items that affect the ease of disassembly of parts other than basic elements. . The correction factors Y in which the correction coefficient is described in advance as a correction index indicating the degree of influence are the decomposition costs Cxyn of each state divided into n when the production environment conditions are aligned.
Is larger than the decomposition cost (assuming Cxyn = Cy) of the correction standard, a functional relationship such that the correction coefficient αn becomes larger in proportion to 1; αn = (Cxyn / Cxyo) y mean... Average for y = (Cxyn / Cy) y mean. Therefore, in addition to the correction coefficient αn being larger than 1, the correction coefficient αx is set for the correction element whose decomposition cost Cxyn becomes smaller than the decomposition cost of the correction standard (Cxyn = Cy).
In some cases, n is smaller than 1.

In this embodiment, Cyxo = Cy, but in addition, Cyxn = Cy, [Cxyn] yn mean = Cy,
Further, instead of the disassembly costs Cxyn and Cxyo, the disassembly time Txyn,
Txyo and these indices Ixyn and Ixyo can also be taken.

In this way, the component disassembly score Ei representing the disassembly of the component is finally obtained, and the details thereof will be described below.

First, the component reference b of the component i is such that the basic element representing the disassembling operation of the component i is one reference element Xo, the correction element is a predetermined size lb, and the production environment conditions are the same as those of the component i. I do. The disassembly cost Cbi is obtained from FIG. 4 and FIG.

Next, a basic element X for each decomposition order j of a part i
ij and the correction element Ynij decomposition cost Cxynij are obtained from FIGS. Hereinafter, Cxynij is abbreviated as Cij.

Here, ΣCij obtained by adding Cij to j is the component disassembly cost Ci. That is, if the component disassembly cost Ci is greater than the component-based disassembly cost Cbi, the component disassembly score Ei of the component is set to a predetermined value (1).
00) is calculated by the following formula: Ei = 100 ± ei = 100 ± gi (Ci) = f2 (Ci).

However, ei = gi (Ci) is a component deduction that increases as Ci increases beyond Cbi. Where ei
Substituting the previously determined εx = f1 (Cx) and αn = [Cxyn / Cx] xmean into the equation, ei = g1 (ΣCij) = g1 (ΣCxynij) = g1 [Σ (αnij · Cxij) = g1 ｛ {[Αnij · f1 ′ (εxij)]} = g2 (αnij · εxij). Here, Cxyn / Cx ≒ (Cxyn / Cx) x mean = αn, and f1 ′ is an inverse function of f1.

Thus, Ei = 100 ± g2 (αnij ·
εxij), and using this formula, the basic deduction εxij and the correction coefficient αnij corresponding to the basic element Xij and the correction element Yij
Can be calculated by

Further, Ei = 100 ± g2 (αnij · εxi
By substituting Ei obtained from j) into Ei of Ei = f2 (Ci), Ci is obtained.

This is convenient because Ei and Ci can be calculated in a simple diagram in which data such as Cx and Cxyn in FIGS. 4 and 5 are not entered.

Instead of the above decomposition costs Cbi and Cxynij, decomposition times Tbi and Txynij and their indices Ibi and Ixynij can be used. Further, instead of the component deduction point ei, a component coefficient ei 'is taken, and the component disassembly score Ei is calculated as Ei = 100ei'.
It can also be. However, ei '= gi' (Ci) is a component coefficient which increases or decreases when Ci exceeds Cbi.

In this way, the component disassembly score Ei and the component disassembly cost Ci are obtained for all the components in this way, and then the disassembly score E and disassembly cost C for the product are obtained from these values.

That is, C = 100 ± e = 100 ± g3
(C) = f3 (C).

However, if e = g3 (C), then C = {C i
This is a product deduction that increases or decreases as it increases beyond Cbi.

Here, in the equation of E, Ei = f2 previously obtained
When (Ci) is substituted, E = f3 (C) = f3 ({Ci) = f3 {[f2 '(Ei)]} = f4 (Ei). Here, f2 ′ is an inverse function of f2.

Instead of the above decomposition costs C, Ci, Cbi, decomposition times T, Ti, Tbi and their indices I, Ii, Ibi can also be taken. Further, instead of the product deduction point e, a product coefficient e 'may be taken and E = 100e'. Here, e ′ = g3 (C) is a product coefficient that increases or decreases as C increases from ΣCbi.

In this way, Ei is an index indicating how easily the component i is easily decomposed, whereas the product degradability score is an index indicating how easily the entire product is easily decomposed.
Here, the approximate expression of f4 (Ei) is (ΣEi) / N.

[0079]

(Equation 7)

The approximate value may be used. Here, N is the number of disassembled parts.

Then, when calculating the disassembly costs C and Ci and the disassembly time T and Ti of the products and parts to be evaluated,
If the disassembly costs C 'and Ci' of existing products and parts similar to the above products and parts and the actual values T 'and Ti' of required disassembly time are known, the disassembly rating of the products and parts to be evaluated The relational expression between E, Ei and similar existing products and disassembly scores E ', Ei' of parts and C, Ci, C ', Ci' is modified as follows.

[0082]

(Equation 8)

.DELTA.Ci = Ci'f5 (Ei, Ei ') Since the comparison is made with similar parts, it is assumed that f5
Is derived.

[0084]

(Equation 9)

∴C = C′f6 (E, E ′) Since it is a comparison with similar products, it is assumed that f6
Is derived.

The above two equations for obtaining C and Ci are obtained by the above-described functions in the following various working environments and processing environments required for the disassembly costs Cx, Cxyn, f2 ', and f3' in FIGS.
A large number of data such as a constant value is unnecessary, which is very convenient.

Ci = ΣCij... Cij is obtained from FIG.

C = ΣCi Ci = f2 ′ (Ei) C = f3 ′ (E) Instead of the above decomposition costs C, Ci, C ′ and Ci ′, decomposition times T, Ti, T ′ and Ti ′ and their Indices I, Ii, I ',
Ii 'can also be taken.

FIG. 6 shows an output example of the evaluation result. The upper diagram of FIG. 6 shows the evaluation result of the evaluation target product, and the lower diagram of FIG. 6 shows the evaluation result of each evaluation target component. As can be seen from the lower diagram of FIG. 6, the evaluation results are in the order of poor rating (the index indicating the difficulty of the work and the processing is large, and the work and the processing are more difficult), which are the index of the easiness of the work and the processing of the parts. It has the function of displaying. Also, for each basic element extracted from the work and processing content of each part,
By providing a function for displaying indices indicating the degree of difficulty of work and processing of the part in descending order, it is possible for the evaluator to indicate a part requiring more design improvement for each part and for each work and processing content. It is possible.

In order to indicate to the evaluator the degree of improvement in the easiness of work and processing for the article or part before the improvement and the article or part after the improvement, the time or the cost required for the work and the processing before and after the improvement. On the other hand, it has a function of displaying a reduction rate indicating the degree of reduction.

FIG. 7 shows a display example of a design improvement case for ease of work and processing, and FIG. 8 shows a method of searching for a design improvement case. This example shows a case where the analysis is as follows: 4 screws Basic element: "Screw rotation""lateralmovement" Flat plate 1 basic element: "Horizontal movement" Flat plate 1 basic element: "Upward movement"

In displaying the improved example, the work and processing contents of the article or part are estimated from the combination of the basic element and the correction element extracted by the evaluator, and the structure of the article or part that requires the work and processing is estimated. Is estimated at least one. Then, for each of the estimated configurations of the articles or parts, at least one configuration example of the articles or parts having the same function as the configuration and which is easier to work and process than the configuration is displayed as an improved example. It has a function. Here, when estimating the configuration of an article or a component that requires work and processing estimated from basic elements and the like and searching for an improved example of the estimated configuration, the information is prepared in advance and stored in a storage device or an external storage device. The improved case database will be used.

In the improvement example shown in FIG. 7, the component configuration before the improvement is a “screw rotation / lateral movement” operation of four screws (in the case of a screw, the screw can be estimated from the basic element “screw rotation”). And two parts (in the case of parts other than screws, the form of the part cannot be inferred from input information such as basic elements) by the “lateral movement” operation and the “upward movement” of the article. Since the work and the processing have been completed, the component configuration as shown in the upper diagram of FIG. 7 is estimated. When there are two or more presumed component configurations for the same analysis content, the evaluator has a function of selecting a component closest to the actual design content from among them.

Here, as shown in FIG. 8, for the estimated or selected component configuration, the cause of increasing the index indicating the degree of difficulty of work and processing is estimated as a problem using the improved case database. Search the countermeasure plan from the improvement case database. In addition, it has been found that it is effective to always reduce the number of components to be considered as an extraction condition of an improvement plan and to reduce an index indicating the difficulty of work and processing.

Next, an improved case is searched from the improved case database based on the searched countermeasure plan, and the improved component configuration is output.

[0096] The improved example has a configuration of an article or part that has the same function as the article or part configuration estimated or selected by the evaluator from the analysis result, but that is easier to work and process than the article or part configuration. Will have. A display example of the improvement example is shown in the lower diagram of FIG. In this example, it is possible to improve the easiness of work and processing of an article or a part by connecting two parts fastened with four screws by fitting in a form considering workability at the time of removal. Is shown. If there are two or more improved examples of such improved cases as in the case of the estimated component configuration, the evaluator can select the optimum improved case by sequentially displaying the improved examples.

Then, for the article or part of the improvement example, an index indicating the degree of difficulty of the article or part before the improvement is calculated by indicating basic elements required for the operation or processing, and an index indicating the difficulty of the article or part before improvement. Also, a function is provided that indicates how much the index indicating the degree of difficulty of working on articles or parts before and after the improvement can be reduced by comparing with.

[0098] Further, an improvement example having the same function as that of the article or part based on the article or part configuration selected by the evaluator or estimated from the analysis result of the work content of the article or part before the improvement. Is displayed. In this case, it is also possible to make it easier for the evaluator to improve the design by displaying the advantages and disadvantages of changing to the improvement case.

[0099] However, there are cases where the presumed configuration contents of articles or parts are not prepared for all combinations of basic elements and the like. Therefore, it is desirable that the improvement case database can be updated at any time because there are cases where the improvement case is suitable or unsuitable. Therefore, the improved case database has a function that can be added, deleted, or changed at any time. The evaluator himself can accumulate the know-how of the user by adding the improved case database to this improved case database, and by incorporating the improved case database of other users, a more effective improved case database can be created. It is also possible to build. For example, by incorporating the evaluation and improvement case display functions of the present invention into a CAD system used by the designer, the designer can register the designed drawing and the evaluation result together and register it as an improvement case without discomfort. It is possible.

FIG. 9 shows the operation by the computer system.

In step 1, "the work to be evaluated and the work of each work type are represented by a combination of basic elements, and each basic element is corrected by a correction element as necessary." However, if there is no symbol that fits perfectly, the symbol of the basic element with the most similar content is selected.

In step 2, for each component, "enter symbols to represent basic elements of work and processing of each work type, symbols to represent correction elements, numerical values, etc. to computer".

If the above operation is performed for all parts constituting the article to be evaluated, the computer automatically calculates all or a part of the score and the work cost or the work time of each part and the article, and the processing cost or the processing time. Then, the result is displayed on the display unit, and the result is output to the printer as necessary.

Basic elements and correction elements are input for each part as input data. The input method is as follows: (1) A method of directly inputting from a keyboard.

(2) A method in which basic elements and correction elements are displayed on a display, and elements are selected and input by moving a mouse or a cursor there.

(3) A method of assigning each symbol of a basic element and a correction element to each key of a keyboard in advance and inputting by hitting the key.

(4) A method of preparing and inputting a dedicated input device (such as a tablet).

It is possible to consider the following. The input method of (1) is convenient when the initials of the names of the basic element and the correction element are used as symbols and are represented by alphabets, and (2)
(3) The input method of (4) is convenient when it is difficult to represent with an alphabet or when the user is not used to keyboard operation.

Embodiment 2 In Embodiment 1, each of the basic elements and the correction elements has a basic deduction point εx and a correction coefficient αn, and the values are substituted into the basic elements and the correction elements input by the evaluator. In doing so, the work and the easiness of processing were required. On the other hand, there is a method of obtaining the easiness of work and processing of an article or a part from given basic elements and correction elements in the following manner.

[0110] The life of the article of the present invention and the outline of each work type described with reference to FIG.
The basic flow of the article or part design and evaluation calculation described with reference to FIG. 3 and the computer system equipped with the evaluation program according to the present invention described with reference to FIG. 3 are common to this embodiment.

However, the configuration of software mounted on the hardware in FIG. 3 is as follows. Storage device 16
The information to be stored in the information, such as the name given to the article or part to be evaluated, information such as numerical values, analysis data such as work and processing elements corresponding to those work and processing content,
An analysis database for estimating the work and processing contents for the article or part from these analysis data, the work and processing contents estimated by the analysis database, basic indexes indicating the degree of difficulty of the work and processing contents, improvement examples A function of inputting, displaying, adding, deleting, and modifying the extracted basic elements and the like required at each processing stage of the evaluation process shown in FIG. 14; a function of outputting the evaluation result to the printer 25 and the display 26; It is a program that has a function to search and display improvement cases and a function to add improvement cases to the improvement case database.

FIG. 10 shows an example of basic elements. The greater the number of basic elements, the higher the accuracy but the more difficult it becomes to use, whereas the smaller the number of basic elements, the easier the element extraction but the worse the accuracy. Empirically, it is good to evaluate with about 20 basic elements, but there is no problem with more than 20 basic elements. These basic elements define predetermined work and processing contents, and can be extracted from information, articles, or parts described in the design drawings. The first column in FIG. 10 shows the name of each basic element, and the second column in FIG. 10 shows the symbol corresponding to each basic element. As shown here, the evaluator's burden is determined by deciding on the symbol, such as “↑” for upward movement or “→” for horizontal movement, so that the work and processing contents of the corresponding basic element can be easily associated with the symbol. It is possible to reduce.

FIG. 11 shows an example of a correction element. The correction element is an item that can be specified by extracting from information, articles, and parts shown in a design drawing, and is an item that affects the ease of disassembly of a part other than the basic element. Examples of the correction element include the material, size, mounting position, and the like of the component, and a number of other elements can be considered.

The correction elements include those used when estimating the work and processing contents of the article or part from the combination of basic elements in the analysis database, and those used in estimating the work and processing contents estimated by the analysis database. It is divided into those used when calculating the time or cost required for processing.

As an example of a correction element used when estimating the work and processing contents of an article or a part using an analysis database, there is an example showing an attachment position of an article or a part. For example, if a component "mounting position low position" is added as a correction element to the removal operation of an article or a part, "squatting" or "standing" when estimating the work and processing contents by the analysis database. Is added.

On the other hand, as an example of a correction element used in calculating the time or cost required for the work and the processing in the work and the processing contents estimated by the analysis database, an example of a correction element indicating the mass of an article or a part is used. There is. When the mass of an article or a part increases, the time or cost required for the work and processing generally tends to increase for the same work and processing contents. Therefore,
When such a correction element is provided, the time and cost required for the operation and processing calculated by the general rule are multiplied by a numerical value of 1 or more as the correction coefficient αn, and the time required for the operation and processing is calculated. Make time or cost corrections. Depending on the type of the correction element, the correction coefficient α
In some cases, n becomes 1 or less.

FIG. 12 shows an example of the contents of an analysis database for estimating the work and processing contents of an article or part from basic elements and the like. As input information, the basic elements shown in the second column of FIG. 12, such as the part names and the number of parts shown in the first column of FIG.
From the information on the correction elements and the like shown in the third column, the work and processing contents shown in the fourth column of FIG. 12 are estimated. For example, it is presumed that the problem that the operator is difficult to grasp during actual work or processing is caused by the correction element that the screw is in the deep hole, and that the driver is more difficult than the basic elements of screw rotation and upward movement. The work and processing contents used are estimated. In addition, this work procedure estimation database is
By changing according to the product or the like, it is possible to estimate a work procedure corresponding to various work environments and products.

By using such an analysis database, the evaluator can simply give input information and the present system can judge the situation and automatically convert it into detailed analysis contents, thereby performing the evaluation with high accuracy.

The fifth column in FIG. 12 shows an example of a basic index indicating the difficulty of the work and processing of the article or part to be evaluated based on the estimated work and processing contents. The basic index includes an index that indicates the difficulty of the task and the process content alone, and a few such as unscrewing using a screwdriver, which often occurs as a series of tasks and processes. In some cases, an index indicating the degree of difficulty is set by summarizing work and processing contents. In some cases, the value changes depending on the correction factor.

Further, as shown in the fourth and fifth columns of FIG. 12, when the number of parts is two or more, the number of parts is not necessarily one.
It is not always the case that the work and the processing content that doubles the work and the processing for the part are estimated and the index indicating the difficulty level is given. For operations and processes that require tools such as a screwdriver, such as removing screws,
The operation of removing the tool from the tool base is performed before the first part, and the operation of placing the tool on the tool base is performed only after the last part.

The sum of the basic indices listed in the fifth column in FIG. 12 is an index indicating the difficulty of the work and processing of the article or part to be evaluated.

With the index indicating the degree of difficulty of the article or part calculated here, the score of the article or part can be calculated as an index of the easiness of work and processing of the article or part. The details are described below.

The total value Gi of the indices indicating the degree of difficulty of the work and the processing of the part is determined by the ratio with the basic index Gbi indicating the degree of the difficulty of the work and the processing of the part having the reference state under the same production environment condition. It can represent the time or cost required to work and process the part. That is, the evaluation component requires time or expense for the operation and processing of the component having the reference state by the cost magnification N times calculated by the following equation.

[0124]

(Equation 10)

Here, the reference state of the article or part is that the work or processing of which the index indicating the degree of difficulty is the least of the work or processing of the article or part is completed. That is, it is assumed that an article or a part to be worked and processed is performed only with the basic element having the smallest difficulty level index.

FIG. 13 shows the evaluation results of work and processing of an article or part having a reference state. This is an analysis of the work and processing of goods or parts, which are basic elements with the smallest index of difficulty in disassembly work and processing, and work and processing are performed only by moving up. The total value of the indices indicating the difficulty levels of Gbi is Gbi.

When the index indicating the difficulty of the work or processing of the article or part is N times the index indicating the difficulty of the work or processing of the part having the reference state, if the index of the work or processing of the article or part is N times as large. Score (E) which is an index of easiness
Is calculated by a function formula that decreases or increases from a predetermined value, E = 100 ± f7 (N). Here, by taking 100 as the predetermined value, a score can be obtained as an index of easiness of work and processing that is generally easy to understand and has a perfect score of 100 points.

The time or cost required for work and processing of the article or part to be evaluated can be estimated by the following procedure.

The time or cost required for the work and processing of an article or part having a reference state under the same production environment conditions can be obtained by measurement and calculation from the production environment under the production environment conditions.
Here, the time or cost required for the work and processing of an article or part having a reference condition is represented by Tbi
Alternatively, if Cbi is assumed, an estimated value (Tfi or Cfi) of the time or cost required for work and processing of the article or part to be evaluated can be calculated by Tfi = Tbi × NCfi = Cbi × N. is there. If the disassembly cost or time of a part is used, it is possible to obtain the score of the part by the method described in the first embodiment.

Here, as Tbi or Cbi, the time or cost required for the work and processing of an article or part having a reference state under the same production environment conditions is usually used. It is also possible. However, in such a case, it is necessary to consider that the estimated Tfi or Cfi includes a difference from a similar production environment condition.

The operation of the computer system will be described with reference to FIG.

In step 1, the work and the processing contents of the component to be evaluated are expressed by a combination of basic elements, and each basic element is input to a computer with a correction element as necessary. If there is a component that is difficult to be expressed as a basic element in the work and processing contents, it is expressed by selecting the symbol of the basic element having the most similar content. In step 2, input data is confirmed, and addition, deletion, correction, and the like are performed.

If the above operation is performed for all the articles or parts to be evaluated, the computer automatically calculates the score for each part and all or part of the time or cost required for work and processing and displays the result. And outputs the result to a printer if necessary. In addition, by automatically searching for and displaying improvement cases, it assists the user in improving the design.
