2. Description of the Related Art In recent years, there have been serious problems such as a shortage of treatment facilities for waste products and environmental pollution during use and disposal of products. Correspondingly, the products, articles and parts are easily processed, more specifically dismantled, disassembled, processed, disposed, etc., and the costs required for them are minimized. It is becoming important to reduce the total life cycle cost of parts. For that purpose, it is easy to collect, dismantle, disassemble, process (crush / sort, recycle, detoxify), dispose (sale, reuse, reuse, discard, store) those products, articles and parts. To achieve this, it is necessary to design and develop products, articles, and parts that have been carefully considered in advance. In addition, once manufactured products, articles and parts have reached the end of their life, dismantling, disassembly, processing (crushing / sorting, recycling, detoxification), disposal (sale, reuse, reuse, disposal, storage), etc. When doing, decide the procedure and method that minimizes the cost incurred for each work,
It is important that work is done accordingly.

In the past, various means have been implemented or proposed to assist in making such designs. As typical examples, firstly, a method implemented as a technique for evaluating ease of assembly, ease of processing, and ease of disassembling when assembling, processing, and disassembling work types are used. To provide design guidelines and casebooks, and how to design while checking the structure under design by the designer, and thirdly, the ease of disassembly and legal information etc. in CAD; ComputerAidedDesign (computer-aided design) System) and the designer refers to the evaluation results and information to design the product.

As a technique related to the first evaluation method, there is a technique disclosed in Japanese Patent Laid-Open No. 6-251024. The second method is Nikkei Mechanical “January 1, 1994”.
Contributions such as "GE Plastics Design Guidelines" published in "0th issue, pages 40 to 48" can be cited.
The third method is the system introduced in the paper entitled "Environmental Total Solution System" published on pages 166 to 169 of the Japan Society of Mechanical Engineers Environmental Symposium '94.

[0005]

In the first method, improvement work and the like based on the evaluation result must be judged by the user to determine which part of the design should be changed and how. I won't. In addition, the work cost of processing, assembling and disassembling the product is targeted for evaluation, and the cost required for the process after treatment and disposal is not considered.

[0006] The second method is based on experience and prior measurement experiments, and lists the structures and material selections and combinations that are difficult to disassemble, recycle and detoxify products. Then, the designer proceeds with the design work while confirming whether or not the design structure proposal under consideration conflicts with the guideline described in the list. In addition, the guideline is qualitative, and its validity can be guaranteed only within the range of case conditions targeted by the preliminary measurement, and it is difficult to judge the quality of the design proposal.

The third method is to evaluate the magnitude of environmental load, but the evaluation in terms of the cost of each process in the life (life cycle) of products etc. does not have sufficient grounds. Also, other information provided is for a person to judge whether the contents of the design proposal are good or not by looking at it, and does not have a function of supporting how to specifically create the improvement proposal.

Reuse, reuse, disposal, storage; disposal costs include costs determined by the purchase price of the market, costs of landfill costs, and other types of costs determined by negotiation with the collector). It is not possible to judge the suitability for each process as a whole.

(3) Evaluation of easiness of processing (crushing / sorting, recycling, detoxification), disposal (sale, reuse, reuse, disposal, storage) during development of products, articles and parts, When making a judgment, the evaluation is performed only by the cost information at the time of evaluation, and the cost when the product, article or part is discarded is not reflected in the evaluation.

(4) Disposal, decomposition, treatment (crushing / sorting, recycling, detoxification), disposal (sale, reuse, reuse, disposal, storage) etc. of waste products when they are processed In addition, when trying to decide a procedure that costs as little as possible, in general, the target product must be put in various types in an irregular order and the wear state is not uniform, so the work procedure Lacking information about, reasonable,
Dismantling, disassembly, processing (crushing / sorting, recycling, detoxification),

DESCRIPTION OF THE PREFERRED EMBODIMENTS As an embodiment of the present invention, a design support method mainly from the viewpoint of recycling when the graphic information shown in FIG. 2 is input will be described with reference to FIG.

FIG. 2 shows the design information inputted in the drawing input 1, which is an article consisting of two parts A, B and C, where the part A is located at the bottom and the part B is the part A.
, Which is located on the upper side, indicates that the part C is connecting the parts A and B. The table below shows that the material of each component is "Fe" or "PVC".

The structure of this apparatus is shown in FIG. This device includes an input device 14, for example, a mouse, a keyboard, a tablet, etc., a storage device 15, for example, a semiconductor memory, a magnetic disk, an optical disk, etc., an arithmetic device 16, an output device 17,
For example, it is composed of a display, a printer, a plotter, and the like.

The storage device 15 stores input information, evaluation calculation results, etc., but by additionally adding a material database 18, an improvement case database 19, a design guideline database 20 and the like, more effective design support is provided. It becomes a device.

The user uses the input device 14 to input drawing information, attribute information, work information, etc. (drawing input 1). However, it is not always necessary to input the attribute information, the work information, and the like. For the information that can be automatically read from the drawing information or the like, it is desirable to reduce the burden on the user by automatically reading from the drawing information. These pieces of information are stored in the storage device 15 in the state as shown in FIG. 4, for example. FIG. 4 shows a part of the contents of the input information.
When the contents shown in are input, for each part, its name, material (these are the input items shown in FIG. 2), position information,
If necessary, record the attribute (for example, in the case of a part that plays a special role such as a screw) and other special notes (in this example, the existence and position of the female thread part) in the remarks column. There is. In addition to this, information such as size and mass information for each part is also recorded.

Then, based on the information stored in the storage device 15, the evaluation calculation is performed by the calculation device 16 (evaluation 2). The evaluation result is stored in the storage device 15. The evaluation 2 may be performed by the user instructing using the input device 14 or may be automatically performed by the arithmetic device 16. The method of evaluation calculation will be described later. Here, an acquisition method of information that can be automatically read from drawing information and the like will be described with reference to FIG. 2 as an example. For example, in FIG.
Considering the work for disassembling each of the parts, the part C has an attribute of “screw” (this attribute is recorded in FIG. 4). It is presumed that "rotation of" is necessary, and from the positional relationship between the component C and the components A and B (for example, information can be acquired from the direction of the center line), the component C is " It can be seen that the operation of "moving upward" after the operation of "rotating the screw using the screwdriver" separates the connection with the parts A and B. It is judged that the part B is simply placed on the part A (if there is information such as adhesion,
It is presumed that the part B will be separated from the part A by the work of "moving upward" from the information and the work of "moving upward". As for assembly, it can be understood that the assembly work of the article can be basically performed by performing the work in the reverse order and the reverse direction of the disassembly. Then, considering the case of maintaining this article, it is estimated that the article is disassembled by the disassembling work, and after the maintenance work, the maintenance of the article is completed by the assembling work (reverse disassembly order, work in the reverse direction). It

Returning to the description of FIG. 1, the arithmetic unit 16 determines the input information based on the evaluation result stored in the storage unit 15 (determination 3). This criterion is stored in the storage device 15 in advance. As a criterion,
Examples include evaluation of the combination of structures and materials (compatibility of the combination), cost, evaluation points described later, and the like. It is desirable that this criterion can be changed by the user. If the result of determination 3 is that the criteria are satisfied, the operation proceeds to the next operation 5. On the other hand, when the standard is not satisfied, the site that does not meet the standard is output to the output device 17 as the recommended change site (change recommended site display 4). At this time, the convenience is further improved by simultaneously outputting the reason why the standard is not satisfied (reason for recommending the change) and the like. In addition, as the output method, design drawings on the display etc., coloring of target parts such as parts list, blinking etc.
There are methods such as designing with printers and plotters, coloring target parts such as parts lists, and shading.

FIG. 5 shows a method of displaying the change proposal, that is, the change proposal search 6 and the change proposal display 7 after the change recommended portion display 4.

In FIG. 5, the arithmetic unit 16 is the storage unit 1.
Based on the evaluation information stored in 5, the information for improving the evaluation result is searched using the arithmetic unit 16 and the storage device 15, and the search result is stored in the storage device 15 (change plan search 6). The stored change plan is output device 1
7 is displayed (change proposal display 7). Further, at this time, it is more effective not only to display the change plan but also to add a function of instructing the change and a function of automatically changing the input information.

Here, the method of executing the change plan search 6 will be described with reference to FIG. 6 by taking an example of material selection in consideration of recycling. The arithmetic unit 16 searches for a material item from the input information stored in the storage device 15 whose contents are shown in FIG. 4 (material search 38).

FIG. 7 shows an example of the material database,
The processing method and cost required for each material are recorded. The category that is the first item shows a rough classification for each material. For example, in another database, "Plastic"
If the classification is performed in consideration of the occurrence of matters corresponding to all, the utility value as a database will be improved. For the material of item 2, record the materials that can be used at the time of design. For example, in addition to records made of general-purpose plastics such as “PS (polystyrene)” and “PVC (polyvinyl chloride)”, formats such as specific product names used by designers on a daily basis may be recorded. At least one method of processing the material is recorded in the processing method of the third item. At the same time, record the processing cost for each processing method in item 4. If the treatment cost is a negative value, it means that profits will be produced, for example, by selling it as a material, and if the treatment cost is a positive value, it means that costs will be incurred, for example, by landfill disposal. . The condition of the fifth term is the third
Record the conditions for realizing the processing method in item 4 and the processing cost in item 4. For example, when the treatment cost varies depending on the purity even if the same treatment method is used, it is possible to record a plurality of treatment costs by the same treatment method and to classify them according to conditions. The alternative material in paragraph 6 records information about which material should be applied as an alternative material when it is recommended to replace the part using the material with another material. Here as well, in addition to recording with general-purpose plastics such as “PS (polystyrene)” and “PVC (polyvinyl chloride)”, specific product names and the like may be recorded. Also,
When recording the substitute material, by recording the usable range of the substitute material and the like at the same time, it becomes possible to appropriately select the material when changing the material. Record in the remarks column of item 7 if there are special notes for each material. For example, in the case of a material that does not occur with a single material, but may cause some problems when combined with another material, describe that fact and enter the combination of those materials. It is possible to output a warning message or the like.

First, from the material database 18 of the storage device 15, it is easy to recycle the material of each part,
A caution is searched for (comparative search 39), and the propriety of using the material is judged based on the result (judgment 3). The criterion for this determination is stored in the storage device 15 in advance. This standard is changed by the user,
It is desirable to be able to add and delete. For example, in the case of FIG. 2, there is a note in the material database 18 that "PVC" which is the material of the component B is "not used as much as possible".
Therefore, in the determination 3, the determination result is issued such that the use of “PVC” is forgotten. Here, as a method of specifying items such as "do not use as much as possible", materials that are not problematic in use are "A", materials that are slightly problematic, "B", material that is problematic are "C", and usage is specified as much as possible. Remember the material by classifying it into ranks such as "D"
The judgment criteria stored in the storage device 15 are “limited to A” and “B”.
It is good to store such as "good until", "good until C", and "allow D". In response to the determination result that “PVC” should be changed, the material database 18 is used to search for an alternative material (alternative material search 40). As alternative materials, "PP", "PS", "PE", etc. are mentioned. Therefore, the output device 17 is provided with “PP” and “P” as a change plan of the part B.
An example of material change to S, “PE”, etc. is shown (change proposal display 7). As an output method, there are methods such as displaying on a display and printing on a printer or plotter. It should be noted that the material database 18 is created based on the actual values and the like, and at the same time, including restrictions such as laws. This content can be provided from the beginning, and it is desirable that the evaluator can also add, change, or delete conditions and methods. Although the above has detected that the material is not desirable and issued a change advice, in addition to this, for example, when the material of one component in the subassembly unit is different from the other components in the unit, When this is detected, the material of the part is the same as the material of other parts in the unit, similar or unlikely to cause a problem during recycling (similarity or occurrence of a problem during recycling) The degree is stored in the material database 18) and is also instructed to be changed. With such a change, a procedure for material separation is not required at the time of processing the waste product, and the processing cost can be reduced.

As a method of adding, changing, or deleting the material database 18, when adding a new material, an item such as "add material database" is selected using the input device 14. By this selection, the arithmetic unit 16
A format for registering a new material is output to the output device 17. The evaluator inputs the information necessary for this format using the input device 14 and stores the information in the material database 18 in the storage device 15, whereby a new material can be added. Further, a case of changing the contents of the database will be described by taking as an example a case of changing the material "PP" in which the recorded rank "A" is recorded. If the recorded rank “A” of the material “PP” is not suitable as the rank “A” due to subsequent legal revisions, etc., the evaluator shall The material database 18 is searched using the input device 14 and the material “P
The item “P” is extracted and output to the output device 17. Then, the input device 14 corrects the rank of the recorded content of the material “PP” from “A” to, for example, “B”, and the changed content is overwritten and recorded in the material database 18. At this time, regarding items other than ranks for the material “PP”,
It is desirable that changes can be made simultaneously on the spot. When deleting a material, the input device 14 is used to search the material database 18 for a material to be deleted, extract the material, and output it to the output device 17. Here, there is a method such that the material is deleted from the material database 18 by executing an instruction such as “delete material”.

As another method for executing the change plan search, a method using the improvement case database 19 and the design guideline database 20 will be described. The evaluator is included in the storage device 15 by the improvement case search 21, and is included in the improvement case database 19 and the storage device 15 whose example is shown in FIG. 9 and the design whose example is shown in FIG. From the guideline database 20, an improvement case plan is searched based on the reason for recommending the change and the input attribute. At this time, it is desirable to be able to search for improvement cases with a plurality of items such as the type of parts, constraints, design guidelines, and improvement examples. Then, the change plan display 7 outputs the change plan to the output device 17.

FIG. 9 shows an example of the improved case database 19. Section 1 records design guidelines. The design guideline may be extracted from the guideline of the design guideline database 20, or may be searched and extracted by the input of the designer. In this search, not only the entire word recorded in the design guideline is targeted, but also a part of the word (for example, "easy disassembly structure" is "easy disassembly") can be searched, More convenient to use. In the target example of the second item, articles, parts, etc. targeted by each design guideline are recorded. Here, by recording from a fine division such as “battery” and “board” to a rough division such as “harmful substance”, the search becomes easy. Section 3 records the design guidelines and the points to be considered at the time of design for each target. This item is an item output to the output device 17. In addition to verbal expression, by recording an example like a figure as in the example, it becomes possible to visually convey the points at the time of design, and more effective design support can be performed. The design guidelines of the first term, the target examples of the second term, and the design examples of the third term do not necessarily correspond to each other one-to-one, but may correspond to many-to-many. For example, in the case of Figure 9,
The two design guidelines, "easy disassembly structure" and "decomposable at the beginning of disassembly work", correspond to both "harmful substances" and "valuable substances", and the design examples are the same in both cases. Has become.

FIG. 10 shows an example of the design guideline database 20. The item of the first term may be searched and extracted by the input of the designer. In this search, not only the entire words recorded in the design guideline are targeted,
Part of the word (eg "hazardous material placement" means "hazardous material")
Etc.) makes it easier to use. For the guidelines in the second paragraph, record the design guidelines to be considered for each item in the first paragraph. This item is output to the output device 17 to provide information to the designer, and the improvement case database 19 described above using the contents of this item is used.
It is also possible to search for design cases and improvement cases. Third
As for the target of the item, the parts etc. targeted by each item are recorded. This item may be retrieved and extracted by the designer's input, or may be automatically retrieved from the design information input by the designer. For example, when the input shown in FIG. 4 is made,
In FIG. 10, from the “screw” which is the attribute information of the part C, “the same material is desirable for the male screw and the female screw” is searched as the “guideline” of “selection of the material”.

FIG. 11 shows a part A "lower case" and a part B.
This is an example in which the component D “battery” is contained in a housing screwed with four “components C” “screws” in combination with the “upper lid”. In this case, it can be seen that the battery is located near the center of the housing (as shown in FIG. 4, the input information also includes position information and size information, and from the combination of these information, It is possible to calculate the placement of the parts in the article).

For example, when the design as shown in FIG. 11 is performed, it is determined in the judgment 3 that the evaluation result does not satisfy the standard, and the change proposal is not displayed at that time, or the user is displayed. When it is determined that the proposed change is not appropriate, the improvement device database 19 is used by using the input device 14.
The design guideline database 20 or the like is searched, and the design guideline database 20 determines that the input attribute is “harmful” based on, for example, the type of the input attribute: “battery”. That is, FIG.
Search for the item: "hazardous material placement" from the target: "battery". As a result, the constraint that disassembly is essential at the time of recycling is extracted, and items such as “easy disassembly structure” and “decomposable early in disassembly work” are extracted as design guidelines. By searching for the relevant items "structure that is easy to disassemble" and "decomposable at the beginning of disassembly work" from the data shown in FIG. Is added ”, and past performance drawings are displayed on the output device 17. That is, FIG.
In the case of designing as shown in (1), in Evaluation 2, the design guideline database 20 determines from the type information “battery” that is the input information of the part D that it is a “harmful substance”, and as a result, at the time of recycling. A constraint that disassembly is essential (I think this constraint is stored in the database as regulatory information by law) is extracted,
As a design guideline, items such as “structure that is easy to disassemble” and “disassembly is possible at the initial stage of disassembly work” are extracted. Then, the improved case database 19 is searched for items such as “easy disassembly structure” and “decomposable at the beginning of disassembly work”, and as a result, items such as “installed at the end of the product and fixed with a special lid” are extracted. As a result, in the determination 3, the component D "battery"
Is determined not to meet the conditions to be satisfied as a design, and is output as a caution component (for example, blinking or coloring of the component on the screen). At the same time, an improved example such as "installed at the end of the product and fixed with a dedicated lid" is displayed on the screen together with the diagram of the design example given in the third item of FIG.

At this time, instead of using the design guideline database 20, a database may be constructed in which an improvement plan is directly derived from the item "battery". Further, when the improvement plan is extracted using the improvement case database 19 and the design guideline database 20, it is desirable that the improvement plan can be automatically performed as in the case of the material database 18. In addition, this improvement case database 19,
The design guideline database 20 is created based on actual values and the like, and at the same time, including restrictions such as laws. This content can be provided from the beginning, and it is desirable that the evaluator can also add, change, or delete conditions and methods. Here, regarding the procedure for adding, changing, and deleting the improvement case database 19 and the design guideline database 20, the material database 1 described above is used.
This is the same as the procedure of addition, change and deletion in 8.

Further, when a change plan is searched or displayed, as shown in FIG. 12, after the change plan search 6, the change plan is evaluated 2 and the output device 17 is displayed on the change plan display 7. At the same time as outputting the change plan to the change effect output 8
Also, by outputting the effect obtained when the change is performed to the output device 17, the convenience is further increased. In particular, when a plurality of improvement plans are searched for in the improvement plan search 6, the evaluation result is displayed for each of these improvements, so that the user can select the improvement plan with the greatest improvement effect. Becomes However, when a plurality of improvement plans are retrieved, it is more desirable to add a function of automatically performing the evaluation and preferentially displaying the improvement plan having the largest improvement effect. At that time, as a method of prioritizing, in addition to the method of giving the highest priority to the improvement plan that has the greatest improvement effect, the method of prioritizing the improvement plan selected in the immediately preceding improvement of the same content, in the past There is also a method of selecting a prioritized improvement plan according to the frequency of selection of the improvement plan selected at the time of performing the same improvement.

An example of the evaluation calculation method in Evaluation 2 will be described by way of example in which the recycling cost is estimated.

The calculation unit has a configuration as shown in FIG.
From the input information 24 obtained by the drawing input 1, for example, items such as part name, material, and mass, the work estimation unit 25
Estimates the disassembling work 27, for example, work such as movement and cutting, using the work database 26. Here, it is desirable that the work database 26 be constructed in accordance with the environment of the disassembling work workplace and the like. Then, the design specification information of the parts, articles, etc. obtained by the disassembling work 27, for example, the part configuration and material information, and in what state each part, article, etc. is about to be discarded, for example, the degree of wear and the like. Based on the above, the processing estimation unit 28 uses the processing database 29 to estimate the processing content 30, for example, operations such as reproduction, crushing / sorting, melting and the like. This makes it possible to estimate not only the standard treatment method that was assumed at the time of product development, but also the optimal decomposition and treatment conditions that take into account the state conditions at the time of disposal. Here, the processing database 29
Should be constructed in accordance with the envisioned processing work environment and equipment information. Then, from the information on the parts, materials, dusts, etc. obtained by the processing content 30, the disposal estimating unit 31 uses the disposal database 32 to dispose of the disposal content 3
3. That is, it is estimated what kind of disposal of the processed parts and articles is appropriate, for example, material sale, fuel sale, parts sale, disposal request, etc. Here, it is desirable that the disposal database 32 is constructed in accordance with the assumed environment / market information of the disposal work workplace.
Then, the decomposition cost 34 is estimated from the disassembling work 27 using the work database 26, the processing cost 35 is estimated from the processing content 30 using the processing database 29, and the disposal cost 36 is estimated from the disposal content 33 using the disposal database 32. The total value of the cost 34, the processing cost 35, and the disposal cost 36 becomes the recycling cost 37. Note that the calculation unit whose configuration is shown in FIG. 13 is included in the arithmetic unit 16 and the storage unit 15.

Here, a method of estimating the processing content 30 and estimating the processing cost 35 will be described by taking the processing database 29 as an example. FIG. 14 shows an example of the processing database 29. The first item is the processing content, which should be recorded in consideration of the situation of the facilities of the facility. The second item is equipment used to perform the process of the first item. For example, it is possible to compare information such as the processing capacity of each facility with the amount of processing to be input, and use it to check the operating status of each facility in advance and to check the periodic maintenance time by estimating the cumulative operating time. It is possible. As for the cost in Section 3, record the cost for implementing the processing contents at each facility. The target of the fourth item indicates a material or the like to which the processing content can be applied. Materials are "PS (polystyrene)" and "PVC"
(Polyvinyl chloride) ”, a specific product name, etc. may be recorded. In addition to the material, there is also a recording method for a specific component such as a "compressor" other than the material. Fifth
The item (final item) describes the precautions, etc. when using the processing and equipment. For example, in the "Selection" column, there is a description that "crushing is required in advance".
For example, "Fe", "Al", and "P" that are the targets of "selection"
It can be seen that even in the case of a group composed only of "P", it is not allowed to perform the "sorting" process suddenly, and it is required to undergo the "crushing" process in advance. In addition, when the group is subjected to "crushing" processing (also in this case, "F
Since "e", "Al", and "PP" are all included in the target material, they can be added to the crushing process), and after that, the "sorting" process is always required, and it cannot proceed to the next process, disposal. I understand.

For example, when there is the input information 24 shown in FIG. 15 (in this example, the work estimating unit 2 calculates from the input information 24).
In No. 5, it is considered that it was determined that the disassembling work 27 was not performed. That is, the processing estimation unit 2 is kept in the state shown in FIG.
8 is input), the processing estimation unit 28 compares the “name”, “attribute”, and “material” items of the input information with the “target” item of the processing database 29. Then, the processing content is selected from the items in which both match. For example, in the example of FIG. 15, “F” included in the “Material” item
All of e, “Al”, “PS”, and “PP” are included in the “target” item of the processing content “crush” of the processing database 29. Therefore, this input information 24 is
It turns out that a process called "crushing" is possible. However, there is a note in the "Remarks" column for "crushing" that "selection is required after processing". Therefore, the item “selection” is searched from the item “processing content” in the processing database 29, and the “target” column is compared with the “material” included in the input information 24. For example, in the example of FIG. 15, all of “Fe”, “Al”, “PS”, and “PP” included in the “material” item are included in the “target” item of the process content “selection” of the process database 29. You can see that it is. As a result, in the case of the example in FIG. 15, the disposal content 30 that the step of “sorting” is performed after “crushing” is estimated. Then, from the “mass” information included in the input information 24 and the “cost” information included in the processing database 29, the processing cost 3
5 is estimated. Work estimation unit 25 using the work database 26, disposal estimation unit 3 using the disposal database 32
The same applies to 1. However, when the work estimation unit 25 estimates the disassembly work 27, the work database 2
In order to consider not only 6 but also subsequent processing contents and disposal contents, the processing database 29, the disposal database 32
May be searched. The same applies when the processing estimation unit 28 estimates the processing content 30.

The contents of each database can be provided from the beginning, and at the same time, the evaluator can add, change, or delete conditions and methods. In addition, when added, changed, or deleted by the evaluator, not only the latest data but also the data of the past several times can be accumulated and weighted to determine the numerical value to be used for calculation. is there. Here, the weighting method puts the most weight on the latest data and reduces the weight as it gets older, so that the latest waste product generation status and the latest technical status are reflected, and a less expensive processing method is presented. It Alternatively, by analyzing changes from the oldest to the newest, it is possible to predict future numerical value fluctuations and calculate the most effective index as data at a certain stage in the future. For example, by providing data retroactively to the past five years as shown in FIG. 16, it is possible to obtain an estimated value of the same index after five years by a technique such as regression analysis. Here, in FIG. 16, a value that is most likely to be generated as a future value is estimated from the accumulation of past data, so that the product will be discarded in the future (for example, when designing the product) (for example, This is an example of how to know the value of the average service life of the product), using the final disposal cost as an example. Enter the value of the final disposal cost from 5 years ago,
In this example, linear regression is used to estimate future final disposal costs. This method can be used, for example, for information such as the take-up price (sale price) of the selected iron.

When the value calculated by the former method is used, the processing cost at the time of evaluation can be estimated. When the value calculated by the latter method is used, the product is It is possible to estimate a value that reflects the conditions that are likely to occur in the future and have a high probability of occurrence.

By changing the contents of the work, treatment, and disposal of the work database 26, the treatment database 29, and the disposal database 32, and the respective costs, the difference in costs due to the facilities and capabilities that differ depending on the facility is taken into consideration. While it is possible to evaluate. In addition, by matching these data with the current situation and information that the facility itself has, and then evaluating the collected waste products, the cost required for processing the waste products at the facility Can be estimated, and can be used, for example, for price determination when the product is collected.

According to the method of evaluation 2 shown in FIG. 13, by inputting design information and the like, for example, in the case of recycling, for example, the work of “disassembly / treatment / disposal” after collection is performed. It is possible to create a procedure plan. It is possible to automatically create a work procedure manual and an instruction manual by outputting the drawing information and the like that are input together with the work procedure plan. This is a product that includes the work procedures required at each stage of the product life, such as assembly procedure, processing procedure and processing method, maintenance method, disassembly procedure and disassembly method, treatment procedure and processing method, disposal method, etc. It can be known at the stage of designing articles and parts. For example, a storage device such as an IC card is used to incorporate this information into a product, article, or component, and the information is read by, for example, an IC card reader or the like to assemble, process, or maintain the product. It is possible to know the method of disassembly, treatment, disposal, etc. without using design information. In particular, at the disassembly, treatment, and disposal sites, it is possible to read out the disassembly, treatment, and disposal methods from randomly input products, which makes it possible to improve the efficiency of disassembly, treatment, and disposal. It is also possible to estimate the cost in advance.

As a storage means for disassembling procedures and disassembling methods, for example, the position of the parts, necessary tools, disassembling method (for example, turning a screw, gripping the screw, and moving it up) in the order of the parts to be disassembled. There are things to remember.

According to the method of evaluation 2 shown in FIG. 13, by inputting design information and taking recycling as an example, the input information 24 indicates the work of "disassembly / treatment / disposal". It becomes possible to prepare a procedure plan and each work procedure. Here, as shown in FIG. 20, the work plan and the work procedure leading to the “disassembly / treatment / disposal” are output to the output device 17 based on the information in the storage device 15 in which the input information is stored. Thus, the work procedure manual 41 and the work instruction manual 42 can be automatically created. For example, taking FIG. 2 as an example, in order to disassemble the part B of the material “PVC”, which is essential for disassembly, by the disassembly estimation unit 25, the part C is first referred to as “screw rotation using a screwdriver”. Disassemble by "move upward" operation, then part B
Disassembly work of disassembling with "movement in the upward direction" 27
Is estimated. In this case, as the work instruction document 42, for example, the output as shown in FIG. 21 is performed based on the design information shown in FIG. 2 and the disassembly work 27. In addition, work instructions 4
As shown in FIG. 21, the work cost (described as work time in FIG. 21) estimated using FIG. Is possible. With this function, work procedures and methods required at each stage of the life of the product, for example, assembly procedures, processing procedures and processing methods, maintenance methods, disassembly procedures and disassembly methods, treatment procedures and disposal methods, disposal methods, etc. Can be known at the stage of designing products, articles and parts. For example, a storage device such as an IC card is used to incorporate this information into a product, article, or part, and the information is read by, for example, an IC card reader or the like to assemble, process, or maintain the product. It is possible to know the method of disassembly, treatment, disposal, etc. without using design information. This function makes it possible to read the method of disassembly, processing, and disposal from products that are randomly input, especially at the site of disassembly, processing, and disposal, and improve the efficiency of disassembly, processing, and disposal. It is also possible to estimate the cost in advance.

As a storage means for disassembling procedures and disassembling methods, for example, the position of the parts, required tools, disassembling method (for example, turning a screw, grasping the screw, and moving it up) in the order in which the parts to be disassembled are disassembled. There is a method such as memorizing).

In addition, as an index different from the cost, the parts score, the product score, and the product score are calculated as an index showing the ease of recycling parts, articles and products and the low recycling cost. It can be used as a reference for comparison with the reference value. However, it is also possible to compare the reference value of evaluation 2 with the value of the recycling cost 37 or the like.

For example, as a formula for calculating the score based on the recycling cost, there is a formula such as rEi = 100−τ × f1 (recycling cost). Here, rEi is a score, τ is a deduction constant, and f1 is a function. As this function, for example,
It is conceivable to set a standard value and use the ratio of the standard value to the recycling cost of parts and articles to be recycled. Here, as the reference value, in this example, "recycling cost when the work with the lowest recycling cost is performed" and the like can be considered.

Also, as a method of calculating the rating based on the ease of recycling, there are the following: ・ For plastic materials of 50 gr or more, if there is a material indication ± 0 If there is no disassembly procedure information +5 If there is no disassembly procedure information -5 ・ Recycling cost is smaller than conventional products +5 Same as -5 Larger -20 ・ There are two or more ways to promote recycling +5 One ± 0 No -10 Calculation method using conditions other than cost is there. In addition to the recycling cost, considering the above-mentioned conditions and the magnitude of the environmental load, the evaluation index calculated for each of these is appropriately weighted and added together to design for comprehensive recycling. There is also a way to check if it is.

By using an index such that the easier the recycling is, or the smaller the recycling cost is, the better the score is, the degree of ease of recycling or the size of the recycling cost can be easily communicated to the evaluator. This is an index capable of pointing out a site to be improved in design, pointing out a site where design improvement is easy, and pointing out a site where the effect of design improvement is great.

It should be noted that when the index calculated by the above-mentioned evaluation calculation method is described, displayed, attached, or attached to a product, for example, when the product is collected as a waste product, a method of recycling or processing from the index thereof is used. And the cost can be calculated. For example, in the case of a product with a decomposition index: dE = 50, a treatment index: d1E = 40, and a disposal index: d2E = 70, the cost required for recycling the product is rC = A1 × (100-dE) + A2 × (100-d1E)
+ A3 x (100-d2E) rC: Cost required for recycling A1: Cost per unit time for decomposition A2: Cost per unit for treatment A3: Cost per unit for disposal It is possible to estimate the cost of recycling roughly without performing an evaluation.

Further, by providing a list of tools and equipment required for maintenance and recycling, describing, displaying, attaching, and pasting the products, it is possible to improve the efficiency of the work.

As another embodiment of the present invention, a design support method for advancing the work while evaluating the material when inputting the graphic information shown in FIG. 2 will be shown.

In FIG. 17, the part A (material Fe) is input in the drawing input 1. Here, in evaluation 2, the material “Fe” is evaluated using the material database 18. The material "Fe" has no particular problem, so judgment 3
Is determined to be “good”, and the process proceeds to the next work 5. Next, the component B (material PVC) is input. Here, in the evaluation 2, the material “PVC” is used by using the material database 18.
Evaluate. Material "PVC" is "Do not use as much as possible"
Since the note is provided, it is rejected in the judgment 3 and the output device 1 to that effect is displayed in the recommended change part display 4.
7 is output. Here, changing the material of “PVC” is recommended, and “PS”, “PP”, and “PE” that are substitute materials for “PVC” in the material database 18 are recommended. However,
It is desirable to be able to change to materials other than the recommended materials. Here, when the material change 23 is performed, the process returns to the evaluation 2 again, and the operation of evaluation is repeated until the material having no problem is selected by the material database 18. If the change is rejected by the material change 22, for example, by using a mechanism that does not proceed to the next operation 5 until the reason for selecting the material is input in the reason input 23, the use of the material that causes no problem to the user Can be encouraged.
In addition, by providing a judgment function using a function of the material database 18 and an approval function by the design manager after the reason input 23, it is possible to further encourage the user to use a material having no problem.

As another embodiment of the present invention, a design support method for inputting the graphic information shown in FIG. 2 will be shown.

The component A (material Fe) is input, and then the component B (material PVC) is input. Next, the component C is input. When the user gives an attribute of "screw" to the component C, which indicates that the component inherently functions as another component, the pair C shown in FIG. In the information determination 9, it is determined that the component C has a paired component, and in the pair information search 10, a component that is considered to be paired with the component C is searched and the component A is extracted. As this extraction method, there is a method of searching for the "thread" or "female screw" to which the component C is to be coupled, from the information of the "screw" of the component C. Next, in the input plan search 11, by using the input plan search database 12 whose example is shown in FIG.
The condition that the same material is desirable is derived, and based on the evaluation result, when the material information of the component C is input, the material of the component A, which is the input item in FIG. 2, is extracted, and Fe is automatically calculated. Displayed or entered. However,
It is desirable to be able to input information different from the information automatically displayed or input by having a function that can be changed by the user. FIG. 19 shows an example of the input plan search database. The first term represents input information, for example, drawing information,
Attribute information, position information, dimension information, etc. are recorded. The second term is inspection information, and should be inspected when the input information applies to the information input in the first term (in this example, a part having an attribute of “screw” is input) ( Record information). For example, in this example, "screw"
The items such as “thread” and “female screw” that should be paired with the part “” are recorded. The third item records the classification of the inspection result of the second item. For example, in this example, the “female screw” mentioned as the item to be inspected in the second item is classified depending on whether or not it exists. The fourth term is a condition for searching for candidates for the input plan. For example, if there is an internal thread for a part called "screw", the screw is
A search is made on the condition that the material is the same as that of the “female screw”, and as a result, the material information of the female screw is searched and displayed as a candidate of the material of the screw, automatically input, or the like.
