阀体制造单元研究与应用

Research and application of manufacturing cell for valve body

基于制造单元模式鲁棒性理论,采用层次分析法(AHP)与模糊评价法研究了影响制造单元模式稳定性的因素,得出了制造单元系统稳定性评判准则,即制造单元鲁棒性因子Ij>70%,产品不合格率<5%,单元制造过程中生产准备时间Fij≌0。阀体制造单元模式运行与计算显示阀体制造单元鲁棒性因子Ij=94%,表明:阀体制造单元系统处于稳定运行状态;阀体制造单元模式生产周期降低了78.5%;生产成本比原来降低了31.8%;阀体生产制造与组织管理能力得到了明显提高;不仅提高了阀体制造生产效率,亦提高了阀体制造生产经济效益。

Based on the robustness theory of manufacturing cell mode, the factors that affect the stability of the manufacturing cell mode were researched by means of analytic hierarchy process(AHP) and fuzzy evaluation method, and then the stability criteria of manufacturing cell system was obtained, that is, manufacturing cell robustness factor Ij>70%, product disqualification rate<5% and preparation time during cellular manufacturing Fij≌0. Operation and calculation results of valve body manufacturing cell mode indicate that its robustness factor Ijis 94%, that means valve body manufacturing cell system is in stable operation; the production cycle and cost reduced by 78.5% and31.8% respectively; the capability of the valve body manufacturing and organization management is significantly improved, which improves valve body production efficiency and economic benefits.
