A real-time scheduling on a shop floor control mini-computer is more important in a FMS than in a conventional shop to deal with a dynamic environment of jobs and processes. Since scheduling is a typical NP complete problem, a two stage heuristic algorithm is adopted for a good (near optimal) solution with a short processing time: (1) initial ordering: simple ordering rule; (2) order improvement: enumeration of alternatives for a successive part of initial order. This fast scheduling scheme was investigated by applications to a Flexible Assembly Line and a flexible-manufacturing cell.
