Propagation mechanism of working procedure time fluctuations in discrete manufacturing process

In order to analyze the influence of working procedure time fluctuations on the production scheduling during the discrete manufacturing process, the propagation mechanism of working procedure time fluctuations in the production process was researched. The concept of correlative module of working procedures was put forward by analyzing the relationship of working procedures. The production process could be composed of 16 kinds of correlative modules of working procedures. The propagation mechanism of working procedure time fluctuations in the correlative modules of working procedures was analyzed, and the propagation flow paths of working procedure time fluctuations were obtained. The working procedure time fluctuations enter into the other flow paths of working procedure via the key deviation working procedure. The key to resolve the problem, to analyze the propagation mechanism of working procedure time fluctuations in production process, is to get the key deviation working procedure of each flow path of the working procedure. The result of application instance shows that the propagation of working procedure time fluctuations can be resolved with algorithm quickly, its' propagation mechanism is the basis of researching dynamic scheduling of the production process, and the algorithm can satisfy the actual requirement of production scheduling.
