PURPOSE: To reduce arrangements work to a minimum number of times and drive an equipment in a high rate of operation, by using the rotary storage and giving an order of priority to the processing so as to supply a product, jig, etc. to each equipment in accordance with this priority.

CONSTITUTION: What product and what jig to be mounted to each tray while a kind of its mounting object to be A or B are controlled corresponding to tray positions P1WP10. When a certain equipment 90 in its process of present execution uses a jib (a) for the product A, if assumed A for exchange subscriber circuit package and B for truck circuit package, each functional test, in which an expected function is different, causes the necessity for a corresponding jig minimizing jig replacement by first processing the product A by a position of the tray and the equipment while a kind of the jig (a) in the present execution, and a rotary stocker 1, being rotatable in both directions, determines a preferential processing order 1W6, causing a control part 15 to perform schedule control.
