TRIZ在轨道交通车辆制造企业生产线生产效能提升中的应用

Application of TRIZ Theory in Production Efficiency Improvement of Rail Transit Manufacturing Enterprises

基于轨道交通车辆制造企业生产线一直存在的工序多、单车生产成本高、生产效能低下等一系列问题,以精益制造与TRIZ(发明问题的解决理论)为依据,结合轨道交通制造企业生产线的建立原则及管理原则,围绕安全环境、质量、生产、成本、设备、人事、信息等7大任务,利用40个发明原理、物质-场分析及76个标准解等创新方法,对影响生产效能的原因进行了细致剖析,通过求解创新了精益管理及精益生产手段,实现了提质、降本、增效的目的,并有效建立起一套可复制、可移植的精益制造工位制节拍化生产线。

There are many problems on the production line of rail transit vehicle manufacturing enterprises,such as multiple processes,high production cost of single car and low production efficiency.To solve the above problems,based on the lean manufacturing and TRIZ(Teoriya Resheniya Izobreatatelskikh Zadatch)innovation method,also combined with the principles of rail transit vehicle manufacturing enterprise production line and management,seven main tasks are selected,including security environment,quality,production,cost,equipment,personnel and information,40 inventive principles,material field analysis and 76 standard solutions are employed,to analyze in detail the reasons affecting the production line efficiency.Then,through the solutions,lean management and lean production methods are innovated,the purpose of improving quality,reducing cost and increasing efficiency is achieved,a set of replicable and portable lean manufacturing station beat production line are effectively established.
