对工艺设计与生产调度集成的必要性和可行性进行了分析，讨论了工艺设计与车间作业计划之间的关系．针对多品种小批量的单件生产车间提出启发式的车间作业计划方法，其决策基于多工艺方案、可替代机床和调度规则，生成车间作业计划，并能及时对车间作业计划进行评价和调整．在此基础上，建立了基于多工艺方案的车间生产作业计划决策系统 The necessity and feasibility of integration of process design and production scheduling were analyzed. The relationship between process design and workshop work plan was discussed. Based on the multi-process scheme, a decision-making method based on multi-variety and small-batch one-piece production workshop is proposed, which can replace the machine tool and scheduling rules to generate the workshop work plan and evaluate and adjust the workshop work plan in time. On this basis, a production planning decision-making system based on multi-process scheme is established
