Abstract:
To provide a technique capable of suppressing the deterioration of parallelism and avoiding a deadlock with a simple design in a manufacturing apparatus which manufactures a plurality of products at the same time.SOLUTION: A process control device (9) includes a deadlock judgement part (15) which refers to such process restriction information that a plurality of operation processes of a manufacturing apparatus and each operation state of a plurality of process execution elements are associated with each other and judges whether falling into such circumstances as to cause deadlock or not when executing an operation process during execution and an operation process scheduled to be executed at the same time, and a process execution control part (14) which delays execution timing of the operation process scheduled to be executed subsequently when it is judged that the deadlock judgement part falls into such a circumference that the deadlock is caused.SELECTED DRAWING: Figure 1
