In other words, (1) After the parts are processed in the processing step, a certain number of parts are put together in a container (called a pallet) for transportation, washed and cooled, and then stored in a storage cabinet.

ことはできない。このため次の問題が発生する。In the above production method, there may be a plurality of combinations of buffers to be taken out when taking out a set of parts satisfying the combination condition from each of the buffers. In this case, the stock quantity of each buffer is influenced not only by the quantity of the parts put into each buffer but also by which buffer the material is taken out from. on the other hand,
In the conventional production method described above, the component dimensions are first grasped in the dimension measurement in the sorting step. Therefore, it is impossible to determine the extraction buffer based on the future input amount to each buffer. This causes the following problems.
（ａ） 前記部品種別・寸法区分別バツフア内に、互い

満杯となり、このため、選別作業が停止する。(B) In the part type / size class buffers, parts that do not satisfy the combination conditions are accumulated and the buffers are full, so that the sorting operation is stopped.
以上の作業の停止のため、生産リードタイムが増大す

出バツフアの決定方法を提供することにある。An object of the present invention is to perform assembly production in which a combination condition is given in advance between dimensions of parts to be combined with each other. The object of the present invention is to provide a method of determining a component take-out buffer in a component assembly production, which secures the stop of the assembly work and the selection work and shortens the production lead time as compared with the conventional method.

きる。In the assembly process, when determining the part extraction buffer, if the future component input amount from the processing process to the selection process can be predicted, the future inventory amount of each buffer can be predicted. Therefore, it is possible to preferentially take out the buffer having a large inventory amount, that is, the buffer having a low possibility of being taken out in the future. Therefore, it is possible to always secure, in each buffer, parts that satisfy the conditions of combination with each other.
