【摘要】:为了实现制造智能化环境下工艺规划决策目标,优化制造资源配置,提出面向智能车间的工艺规划辅助决策方法.以零件加工特征为基础,将含有加工工序和设备信息的历史工艺规划方案视为云服务资源,通过制定语义匹配策略,初步匹配出待选工艺规划方案集.把工件的加工时间、加工成本、在工序间的转运距离与设备实时状态效用作为优化目标,引入罚函数建立适应度函数模型,运用改进群领导优化算法在待选规划方案集中优选出最佳方案.通过实例验证了该方法的有效性.
[Abstract]:In order to achieve the goal of process planning decision in intelligent manufacturing environment and optimize the allocation of manufacturing resources, a process planning assistant decision method for intelligent workshop is proposed. Based on the feature of parts processing, the historical process planning scheme which contains the information of processing process and equipment is regarded as cloud service resource. By making the semantic matching strategy, the set of process planning schemes to be selected is preliminarily matched. Taking the processing time, the processing cost, the transfer distance between the processes and the real-time utility of the equipment as the optimization objectives, the penalty function is introduced to establish the fitness function model. The improved group leadership optimization algorithm is used to select the best scheme in the selection plan. The effectiveness of the method is verified by an example.
