Note that experimental values are usually used for the fastening method and the disassembly time.

Next, the product evaluation index calculated by the product evaluation index calculation section 170 is displayed on the display section 180 (step ST116). Thereafter, the operator, if necessary, retrieves the part configuration stored in the memory unit 110, the material and mass of all the child parts constituting each part, the disassembled parts or child parts, their order, and the fastening method.

FIG. 9 is an explanatory diagram showing an example of editing processing using the editing unit 190. In the case of manual disassembly, the parts (or child parts) to be removed are limited, and are, for example, hard-to-crush materials that cannot be crushed by a crusher and harmful substances containing harmful substances. In some cases, valuables may be removed,
In general, after crushing, it is generally separated by magnetic separation or the like. In the example of FIG. 9, the child part 1 under the part 1 has to be removed because it is difficult to crush or a harmful substance. Therefore, after the fastening method 1 of the part 1 is released, the child part 1 is fastened. Method 2 was canceled (before change).
After the change, since the child part to be removed has been moved below the part 2, there is no need to release the fastening of the part 1,
After releasing the fastening of the component 2, the fastening of the child component 1 is released. The fastening method in this case is different from the fastening method before the change. Further, if the material of the child component to be removed is changed, it is not necessary to remove the child component, so that it is not necessary to release the fastening (the fastening method is not entered).

As described above, by editing the data of all parts and child parts of a product, it is possible to examine a specific method of improving the product design. After the data is changed, the product evaluation index calculating section 170 recalculates the product evaluation index using the data (step ST115), and displays the calculation result on the display section 180 (step ST116).

Next, the calculation of the recyclable rate as an example of a product evaluation index will be described. FIG. 10 shows the recyclability ratio calculation unit 171 in the product evaluation index calculation unit 170.
Is a flowchart showing a flow of a process of calculating a recyclable rate according to the first embodiment.

When the process is started, the recyclable rate calculator 171 first initializes the mass of the entire product and the recyclable mass to 0 (step ST201).
Next, the mass (n) of the child component and the recyclable mass (n) of the child component are calculated for each child component by the following equation (step ST202). Mass of child part (n) = volume of child part (n) x specific gravity corresponding to material of child part Recyclable mass of child part (n) = mass of child part (n) x recyclability

Next, as shown in the following equation, the mass (n-1) of the child part calculated in step ST202 is added to the mass (n-1) of the product so far, and the recyclable mass of the product so far. The recyclable mass (n) of the child part calculated in step ST202 is added to (n-1) to calculate the mass (n) of the new product and the recyclable mass (n) of the new product. (Step ST2
03). Product mass (n) = Product mass (n-1) + Child component mass (n) Product recyclable mass (n) = Product recyclable mass (n-1) + Child component recyclable mass ( n)

This step ST202 and step S202
The processing of the calculation in T203 is repeatedly executed for all the child parts. When the processing for all the child parts is completed, the recyclable rate of the entire product is calculated according to the following equation (step ST204), and a series of processing by the recyclable rate calculating unit 171 is completed. Product recyclability = Product recyclable mass /
Product weight

Next, the calculation of the recoverable value as an example of the evaluation index of a product will be described. FIG. 11 is a flowchart showing the flow of the recoverable value calculation process by the recoverable value calculation unit 172 in the product evaluation index calculation unit 170.

When the process is started, the recoverable value calculation unit 172 first initializes the recoverable value of the entire product to 0 (step ST301). Next, the recoverable value (n) of the child part is calculated by the following equation for each child part (step ST302). Recoverable value of child parts (n) = mass of child parts (n) x recyclable rate x sale price

Next, as shown in the following equation, the recoverable value (n) of the child part calculated in step ST302 is added to the recoverable value (n-1) of the product so far, and a new value is obtained. Calculate the recoverable value (n) of the product (Step S)
T303). Product recoverable value (n) = Product recoverable value (n-
1) + Recoverable value of child parts (n)

Step ST302 and step S302
The processing of the calculation in T303 is repeatedly executed for all the child parts. When the processing for all child parts is completed, a series of processing by the recoverable value calculation unit 172 is completed.

Next, calculation of a recoverable cost ratio as an example of a product evaluation index will be described. FIG. 12 shows the recoverable cost ratio calculator 1 in the product evaluation index calculator 170.
It is a flowchart which shows the flow of the process of the recoverable cost ratio calculation by 73.

When the process is started, the recoverable cost ratio calculator 173 first initializes the recoverable value and the material procurement cost of the entire product to 0 (step ST40).
1). Next, the recoverable value (n) of the child part and the material procurement cost (n) of the child part are calculated for each child part by the following equation (step ST402). Recoverable value of child parts (n) = mass of child parts (n) x recyclable rate x selling price Material procurement cost of child parts (n) = mass of child parts (n) x
Purchase cost

Next, as shown in the following equation, the recoverable value (n) of the child part calculated in step ST402 is added to the recoverable value (n-1) of the product up to that time, and The above-mentioned step S to the material procurement cost (n-1)
The material procurement costs (n) of the child parts calculated in T402 are added to calculate the recoverable value (n) of the new product and the material procurement cost (n) of the new product (step ST403). Product recoverable value (n) = Product recoverable value (n-
1) + Recoverable value of child parts (n) Material procurement cost of product (n) = Material procurement cost of product (n-1) + Material procurement cost of child part (n)

Step ST402 and step S402
The processing of the calculation in T403 is repeatedly executed for all the child parts. When the processing for all the child parts is completed, the recoverable cost ratio of the entire product is calculated according to the following equation (step ST404), and a series of processing by the recoverable cost ratio calculation unit 173 ends. Recoverable cost ratio of product = Recoverable value of product / Material procurement cost of product

Next, calculation of a recycling cost as an example of a product evaluation index will be described. FIG. 13 shows a recycling cost calculator 174 in the product evaluation index calculator 170.
Is a flowchart showing a flow of a process of calculating a recycling cost according to the first embodiment.

When the process is started, the recycling cost calculator 174 first initializes the disassembly time of the entire product to 0 (step ST501). Next, using the contents of the disassembly time database 160, the disassembly time (n) of the product is calculated by the following equation (step ST502). Product disassembly time (n) = product disassembly time (n-1) + disassembly time of part or child part (n)

The calculation process in step ST502 is repeatedly executed for all the dismantled parts and the dismantled parts. When the processing for all the dismantled parts and the dismantled parts is completed, the recycling cost of the entire product is calculated from the obtained dismantling time data and the recoverable value obtained by the recoverable value calculation unit 172 according to the following formula (step). ST5
03), a series of processing by the recycling cost calculation unit 174 ends. Recycling cost = dismantling time x labor cost (constant)-recoverable value of product

Next, the calculation of the environmental load in the material will be described. FIG. 14 is a flowchart showing the flow of the process of calculating the environmental load on the material side of the entire product by the environmental load calculating section 175 on the material side in the product evaluation index calculating section 170.

When the process is started, the material load environmental load calculation unit 175 first initializes the material load of the entire product (step ST601). Generally, the environmental impact of the entire product depends on the manufacturing process, transportation process,
Calculated as the sum of the use process, disposal process, and environmental impact of materials used in products. In this process, the data of each environmental load of the manufacturing process, the transport process, the use process, and the disposal process of the product is fixed, and only the environmental load of the material of the product is calculated. Therefore, the environmental load (1) on the material side of the product, which is the initial value, is given by the following equation. Environmental impact on product materials (1) = Manufacturing process data (constant) + Transport process data (constant) + Use process data (constant) + Disposal process data (constant)

Next, the environmental load (n) on the material side of the child part is calculated for each child part by the following equation (step ST60).
2). Environmental load (n) on the material side of the child part = mass (n) of the child part x environmental load coefficient

Next, as shown in the following equation, the environmental load (n-1) on the material side of the product up to that point is calculated in step ST6.
Environmental load (n) in the material aspect of the child part calculated in 02
Is added to calculate the environmental load (n) on the material side of the new product (step ST603). Environmental load on material of product (n) = Environmental load on material of product (n-1) + Environmental load on material of child parts (n)

This step ST602 and step S602
The processing of the calculation in T603 is repeatedly executed for all the child parts. When the processing for all child parts is completed, a series of processing by the environmental load calculation unit 175 on this material side is completed.
