摘　　要：针对订单生产型企业JIT准时供货的要求,建立了加工和装配计划集成模型,该模型的目标函数是为了保证产品交货期的要求;为保证计划的可行性,约束函数包括加工能力约束、装配能力约束、加工和装配顺序约束;模型为两层混合规划模型,运用了遗传算法和启发式规则,提出了混合启发式算法。最后,针对某按订单制造型企业进行了实例应用,对产品制造过程进行了分解,采用先由装配计划得出各工件的交货期,然后根据工件的交货期确定工件的加工和装配计划。An integrated model of machining and assembly planning was constructed in order to deal with manufacturing in a JIT production system of MTO（manufacturing to order） enterprise for delivery just--in- time. Function objective of the proposed model was to guarantee the due dates of production. Restraint functions included machining capacity, assembly capacity, machining and assembly procedures restraints. Feasible planning can be set down considering these restraints. To build up two level mixed programming model, a hybrid heuristic algorithm based on genetic algorithm and heuristics rules was put forward. Integrated model was used in a shop of a MTO company. By decomposing manufacturing planning, due dates of each parts can be achieved by assembly planning and machining sequence of parts can be ascertained according to due dates of each parts.
