., those high loads working stations could not complete the assignment in time while those low loads ones often have to pause for lack of material, which causes loss of working hour as well as blocking of large number of work pieces, seriously, may be result the interruption of the production.
Modeling classes [1] category function icon and meaning entity class physical resources such as equipment, processing object, the operator working station storage material info class process planning, production plan event controller factory calendar controller class production process control, logistics control procedure for controlling by Simple++ procedure class production line bottleneck analysis, working hours analysis equipment utilization rate bottleneck analyzer result class equipment load and productivity production tasks to complete the table Fig. 2.
Not only the consumption of production source and working hour could be predicted, but also the rationality of production planning could be assessed, and to provide the science data for production adjustment, which makes the enterprise obtains the ability of rapid response to market demands.
