【摘要】：为更好地减少制造过程中的碳排放,弥补将工艺规划与车间调度分开碳排放优化时忽略了工艺规划方案中加工方法和工艺路线对调度阶段各工序加工机床分配方案、搬运距离以及工件加工顺序的影响,提出一个集成优化工件各特征加工方法、工艺路线、工件加工顺序以及各工序的机床分配,以实现制造过程碳排放和最大完工时间最小的多目标集成优化模型;针对集成优化模型中优化参数较多且相互影响的特性,提出一种前后相关联的四段式编码方法,采用NSGA-II算法求解,通过将所得的集成优化结果与先进行面向低碳的单目标工艺规划优化,再进行面向低碳的多目标车间调度分开优化结果进行对比,说明提出的集成优化模型可以得到更低的制造过程碳排放和完工时间,从而验证了集成优化模型的有效性。
[Abstract]:To better reduce carbon emissions in the manufacturing process. When the process planning and workshop scheduling are separated by carbon emission optimization, the process planning method and the process route are neglected to allocate the machine tool in the process planning stage. This paper presents an integrated and optimized machining method, process route, workpiece processing sequence and machine tool allocation for each working procedure, due to the influence of moving distance and machining sequence of workpiece. In order to realize the multi-objective integrated optimization model of carbon emission and minimum completion time of manufacturing process; In view of the characteristic that the optimization parameters are many and affect each other in the integrated optimization model, a four-segment coding method associated with each other is proposed, which is solved by NSGA-II algorithm. The integrated optimization results are compared with the low carbon oriented single objective process planning optimization results and the low carbon oriented multi-objective job shop scheduling optimization results. It is shown that the proposed integrated optimization model can obtain lower carbon emission and completion time of manufacturing process, thus validating the effectiveness of the integrated optimization model.
