Research on the Subpackage ProcessPlanning and Application ofEngine Assembly Line

Zhang Peiwen （Beijing Foton Cummins Engine Company，Beijing102200）

Abstract：With the increasing prevalence of small batchand multi varietyproductionmodes in theautomotive manufacturing industry，engine companies have developed a large number of modular subpackage scenarios to adress thedifferences inthenumber of workstations，personnel configuration，and process layout betweendiferent engines underthismode，andfurtherenhancetheeficiency，flexibilityandscalabilityofproductionlines.Thispapertakesan engineassemblyproduction lineasanexampleto compare theconceptsand characteristics of2modes，namely，online subpackage and centralized subpackage.The design parameters of the2 subpackage modesareexplained，anda mathematical model of process quota is proposed.MATLAB is utilized to simulate the relationship between process quota and output in thecentralizedsubpackage mode，andthe critical conditions for lean management of the 2 subpackage modesare obtained to improve leancontrol capabilities and provide reference for subpackage planing of related production lines.

Keywords：Online subpackage，Centralized subpackage，Mathematical model of processquota，Lean managementandcontrol

1前言

发动机作为汽车制造过程中劳动密集型的环节，装配工艺复杂、制造过程各类生产要素众多、生产周期长、各产品间差异大，导致不同产品的制造周期不相等、操作人员配置和工艺布局差异明显，而且受供应链策略影响，众多零件分体供货，更增加了工艺规划难度，因此，越来越多的企业关注模块化分装场景的应用和优化[-4]。（剩余5072字）
