摘　　要：针对精益化生产系统需要拉动式生产控制以保障其即时性和集约性,而看板系统对生产波动较为敏感,无法适应具有多品种、小批量的船舶建造特征的船舶产品生产的问题。CONWIP(Constant work-in-process,固定在制品)系统结合了推式和拉式生产的优点,通过调节生产线中的在制品投入量,减少产品积压,缩短生产周期。本文提出无缝钢管及紫铜管生产线CONWIP控制方案,基于DOE理论对方案中重要参数进行选择验证,结合虚拟仿真技术对比选择并优化控制方案。验证了CONWIP控制系统的适用性和优势,有效解决了船舶管子生产周期长、阻塞严重等问题。Aiming at lean production system needs pull production control to ensure its immediacy and intensity,but kanban system is sensitive to the production fluctuation and cannot adapt to the production of ship products with the characteristics of multi-variety and small-batch ship construction.The CONWIP(constant work-in-process)system combines the advantages of push and pull production to reduce product backlogs and shorten production cycles by adjusting wip inputs in the production line.In this paper,the CONWIP control scheme of seamless steel pipe and red copper pipe production line is proposed.Important parameters in the scheme are selected and verified based on DOE theory,and the differrent control schemes are compared,selected and optimized by combining with virtual simulation technology.The applicability and advantages of CONWIP control system are verified,and the problems such as long production cycle and serious blockage are effectively solved.
