Here, out of the number of parts calculated in step S802, the number of parts to be put into the assembly process from the present time to the time set in step S801 is calculated. Next, the new parts in the warehouse are calculated at the determination time (step S804).
Here, a value obtained by subtracting the value calculated in step S803 from the value calculated in step S802 is obtained.

FIG. 9 is a flow chart showing the processing contents of the calculation of the amount of recyclable parts to be loaded (step S703).
First, the determination time is set (step S901). Here, the timing for determining the number of input parts from the production plan is set.

Next, the collected parts that can be reused by the judgment time are calculated (step S902). here,
The inventory quantity of the collected product at the present time and the quantity of the parts constituting the product collected by the time set in step S901 and which can be reused by the judgment time are calculated. The number of parts that can be reused is the number of parts that make up the recovered product at the present time, although the judgment time is greater than the remanufacturing time of the part, but the parts that make up the product collected by the time set in step S901 are , The sum of the judgment time and the number of times when the judgment time is greater than the recovery time and the number of parts remanufacturing steps.

In this suitability determination process, the sum A of the new component amount calculated in the new component inputtable amount calculation (step S702) and the recovered component amount calculated in the recovered component inputtable amount calculation (step S703) is obtained.

Next, production plan creation (step S701)
Let B be the quantity of parts set in. Then, these A and B are compared. As a criterion for judging suitability, if A / B <X1, inventory quantity is insufficient, if X1 ≤ A / B ≤ X2, inventory quantity suitability A / B> X2, excess inventory quantity (however, X
1 is a value of 0 or more and 1 or less, and X2 is a value of 1 or more), and the determination result is output.

If the recyclable component chargeable amount calculated in step S703 is a variable value having an upper limit value and a lower limit value, the A / B value is calculated for each of the upper limit value and the lower limit value. Then, the suitability for the inventory quantity is determined.

According to the first embodiment, it is possible to optimize the stock quantity of the parts that need to be newly procured from the production plan and the reusable quantity and the timing of the parts constituting the collected product. As a result, unnecessary parts can be removed and the cost of parts related to the procurement of newly procured parts can be reduced.
At the same time, it is possible to optimize the inventory quantity of the recovered parts to be reused and to eliminate unnecessary inventory and balance with the inventory of newly procured parts.

(Second Embodiment) Next, a second embodiment of the present invention will be described. In the second embodiment, the reuse determination of a component is performed using the usage time of the product in the market, and the inventory quantity of a new component is managed from the reusable number of components calculated as a result.

FIG. 10 is a block diagram showing a configuration example of the collected product management device 212 according to the second embodiment of the present invention. 10, the same components as those shown in FIG. 5 are designated by the same reference numerals. As shown in the figure, in the second embodiment, a magnetic memory 1002 is mounted on the collected product (collection machine) 1001, and the usage time in the market is recorded. Then, the magnetic memory reader 1003 reads the market usage time recorded in the magnetic memory 1002 when the product is collected.
This information is output to the reuse determination module 523,
Used for reuse judgment. The result of reuse judgment is
It is recorded in the collected product management server 519.

According to the second embodiment, it becomes possible to easily judge the reusability of the parts constituting the collected product from the use time, and it is possible to judge beforehand whether or not all the parts are reused. Since it becomes possible to extract reusable parts based on the determined consumption time, etc., disassembling the entire product can be eliminated, and the work cost can be reduced.

(Third Embodiment) Next, in the third embodiment, the reusable number of parts is calculated as data having variations with upper and lower limits, and variations in actual values (use times) of the components are calculated. This is a structure for absorbing more appropriate inventory management.

FIG. 11 is a table showing an example of standard values of the reusable time of parts. Reuse determination module 523
Determines whether or not the parts constituting the recovered product are reusable by referring to the usage time in the market shown in FIG. For example, for the part A, if the usage time in the market is 12 kh (= 12 × 1000 hours, unit notation is the same below) or less, reusable, if 13 kh to 17 kh, simply reusable from the usage time It is impossible to judge. Whether or not reusable is judged based on the inspection result (necessary inspection), and if it is 18 kh or more, it is set to be not reusable.

FIG. 12 is a diagram for explaining the procedure for calculating the number of reusable parts. Collected products (collection machine) 1
Each of 201 and 1202 includes 10 parts A and B parts.
5 and three parts C. The product (collection machine) 1203 is composed of five parts A and five parts B. Each of the products 1201 to 1203 is reusable (○ in the figure), non-reusable (x in the figure), and incapable of determining whether or not reusable (Δ in the figure) for each component based on the usage time of the product. Distinguished by type. The number of parts that cannot be judged to be reusable corresponds to the above variation.

For example, the product 1201 has a usage time of 10 kh in the market, and the parts A, B, and C have the same usage time. The reusability determination module 523 compares the reusable time standard value shown in FIG. 11, and the part A is reusable,
It is determined that the part B cannot be reused, and the part C is reusable. The products 1202 and 1203 are similarly determined, and the reusable number calculated as a result is the number of parts A
Is in the range of 10 to 20, the part B is in the range of 0 to 5,
The number of parts C is six.

The above results are used for calculating the type and number of collected parts that can be input by the determination time in the calculation process of the collected part amount (step S902 in FIG. 9). In addition, in the setting shown in FIG. 11, if there is no item (use time) corresponding to the inability to determine the reusability, it indicates that there is no variation in the type and number of collectable parts that can be put in.

Further, it is also possible to adopt a configuration in which the time range in which it is not possible to judge the availability of the collected product is corrected by the setting shown in FIG. In this case, the reuse determination module 523 determines using the corrected value when determining whether or not the component can be reused from the usage time information for each component constituting the product.
As described above, by correcting the variation in the reusability of the components constituting the collected product from the actual value, it becomes possible to more accurately set the variation of the reused components.

According to the third embodiment, a process for judging the reusability of the parts constituting the collected product as the reusability judgment cannot be made based on the standard value of the reusable time is added, and the information having dispersion is obtained. to manage. As a result, it becomes possible to properly absorb the variation in the actual values of the reused parts and appropriately determine the reuse. Further, by correcting the variation in the reusability of the component from the actual value, it becomes possible to more accurately set the variation in the reused component.

(Embodiment 4) Embodiment 4 is configured to calculate the man-hours for remanufacturing the parts based on the usage history of the product in the market, specifically, the usage time. FIG. 13 is a chart showing an example of man-hour setting of the recycling process based on the usage time. Items and man-hours for the recycle process required for reuse are set according to the parts that make up the recovered product and according to the usage time in the market. The unit of man-hour of each item is minute [m].

For example, for the part A, if the market usage time is 12 kh or less, the man-hour of the cleaning process is 10 minutes. If the usage time in the market is 13 to 17 kh, the man-hours of the inspection process are 15 minutes, the man-hours of the recycling process and the man-hours of the cleaning process are 10 minutes based on the inspection result. If the usage time in the market is 18 kh, it cannot be reused and will not be the target of the remanufacturing time calculation. Then, for the part A, since the man-hours in the remanufacturing process have a variation of 10 to 20 minutes, the actually necessary man-hours for remanufacturing are calculated based on the inspection result.

FIG. 14 is a diagram for explaining the procedure for calculating the required number of remanufacturing steps for recyclable parts. The component configuration of the recovered product and the usage time in the market are the same as those described with reference to FIG. For product A,
Since the usage time in the market is 10 kh, the required remanufacturing time for reusing the part A is only 10 minutes of the cleaning process from the definition of FIG. 13, and the total remanufacturing time (total remanufacturing time) is also 10 minutes. It will be a minute. The other parts B and C are also shown in FIG.
Similarly, the man-hours are calculated by using. At this time, the regeneration man-hour,
Some parts have variations in the number of reusable parts. The above result indicates that the amount of collected parts is calculated (step S90 in FIG. 9).
In 2), it is used to calculate the type and number of collected parts that can be put in by the judgment time.

As described above, by individually calculating the man-hours of the recycling process (cleaning process, inspection process, recycling process) required for reusing the component from the usage time for each component constituting the collected product. It is possible to obtain only the required remanufacturing process according to the usage time of the parts, and easily obtain the man-hours of the corresponding remanufacturing process, so that man-hour management in the remanufacturing process can be performed appropriately and efficiently. become.

Although each process of the above-mentioned recycling process and the calculation of the man-hours are made based on the usage time of the product, the invention is not limited to this, and the usage history of the product can be used. As the usage history of the product, information on the failure or repair of the recovered product or part is used. Further, the man-hour required for the reproducing process can be treated as information having variations including an upper limit value and a lower limit value.

FIG. 15 is a block diagram showing another configuration of the newly procured parts management apparatus 211. The same components as those in FIG. 3 are designated by the same reference numerals. As shown in the figure, in the configuration of this figure, a component procurement module 1501 is provided.
