针对某企业手工装配作业环境，认为生产控制系统的调度策略必须建立在人机互助的基础之上。在具体操作时，提出用Ｐｅｔｒｉ网规范装配工艺流程，基于关键工序点进行控制，即：１）按周期计划安排生产；２）按日进度计划用Ｐｅｔｒｉ网预测缺件；３）基于关键工序点的在制品控制；４）定期盈亏检查，从而达到对装配产品信息流的动态控制和科学管理。这些策略与方法来源于企业，适合中国国情，因而具有实用性和推广价值。
According to the manual assembly work environment of an enterprise, it is considered that the scheduling strategy of production control system must be based on the mutual aid of man and machine. In the specific operation, Petri nets are proposed to standardize the assembly process and control based on the key operation points, namely: 1) arrange the production according to the cycle plan; 2) use Petri nets to predict the missing parts according to the daily schedule; 3) Of the in-process control; 4) regular profit and loss inspection, so as to achieve dynamic control of assembly flow and scientific management of products. These strategies and methods derived from the enterprise, suitable for China’s national conditions, which has practical and promotional value.
