FACILITY OPERATING METHOD

摘要

A facility line where the operation-time does not exceed the initially-set operation-time is established by selecting facilities required for working a specific product from a plurality of facility groups. The priorities for the facilities to which parts are assigned are divided into groups based on the features of the facilities. The information on the priority order among the facilities within each group, the priority order among the groups, parts-mounting operation-time of the parts mountable by the facilities, and the operation-time specific to the facilities is controlled at external storing means (1) as control information (2). After facilities selected in accordance with the priority order are added to line constitution until all required parts are mounted, the operation-time of the line is calculated by calculation unit (3). Then, until the operation-time of the line no longer exceeds the initially-set line operation-time, facilities selected in accordance with the priority order are added to the above-mentioned line constitution, and the operation-time of the line is calculated by the calculation unit (3).
