A Petri Net Model for Part Sequencing and Robot Moves Sequence in A 2-Machine Robotic Cell

This paper deals with part sequencing and optimal robot moves sequence in 2-machine robotic cells according to Petri net graph. We have assumed that the robotic cell is capable of producing same and different parts. We have considered a new motion cycle for robot moves sequence which is the development of existing motion cycles in 2-machine robotic cells. The main goal of this study is to minimize the cycle time by determining the optimal part sequencing and robot moves sequence in the robotic cell. So, we have proposed a model based on Petri network.

浅析对供应商4M变更的规范管理

随着顾客对产品的个性化需求越来越细化,为了适应这种市场化的要求,大型企业一方面需要遵循严格的产品规范要求,同时又需要对市场变化做出迅速反应,满足不同客户的需求。产品多样小批量的生产变化对提供产品服务的企业运营提出了很大的挑战,同时对管控产品质量的风险加大。文章通过研究对供应商4M变更管理规范的要求,探讨企业在实际生产过程中针对供应商4M变更的规范管理,有效防范供应商产品4M变更的风险,使企业在当前的生产模式中竞争地位不断增强。
