<p>PROBLEM TO BE SOLVED: To prevent stagnation of production lots by effectively managing the volume of production in entire facilities. SOLUTION: The method includes a step S10 of receiving unit operating-state data in each facility from each facility server, a step S20 of judging the presence or absence of specific one of the facilities which issued abnormal unit operating- state data, a step S30 of judging whether or not all units in the specific facility are in their not-operated state in the presence of the specific facility which issued the abnormal unit operating-state data, a step S40 of cutting off all step condition data downloaded in the specific facility when all the units of the specific facility are in the not-operated state, and a step S50 of grasping not-operated one of the units in the specific facility and then cutting off specific step condition data downloaded in the not-operated unit when all the units of the specific facility are not in their not-operated state. As a result, the overall volume of production can be effectively managed and accumulation of a flow of lots can be prevented.</p> |
