PROBLEM TO BE SOLVED: To provide a production system to prevent a stop of operation of a production system in the middle of a machining schedule and further, and reduce the frequency of the occurrence of a work in process to a maximum limit. SOLUTION: A work master producing part 11 produces a machining program name at each process and a work master to register all tools used at a machining program, and produces a machining schedule, where a work name, the number of workpieces, and a machining method are registered, by a machining schedule producing part 12. Through operation starting indication from an operation starting indication part 13, a subsequent work process deciding part 14 decides a subsequent work process from a work process prohibition information produced by a machining schedule, a work master, and a work skip part 18 and performs machining, in order. Work process prohibition information produced by the work skip part 18 is produced when it is decided by a necessary tool deciding part 16 or a machining program deciding part 17 that machining is impracticable. A work process that machining is impracticable is prohibited and further, a following work process for the work is prohibited, and information to prohibit a whole work process for a work containing a work process where it is decided that machining of a work following the work is impracticable is produced.
