多品种少批量制造环境下的改进型生产系统

Improved production management system in multi-specification and small-batch production environments

为在多品种少批量制造环境下实现准时制精益生产模式,研究了多品种少批量制造环境下的生产物流特性,构建了一种该环境下的准时制物流体系。通过分析对比看板、鼓-缓冲-绳和固定在制品三种控制策略的优缺点,提出了一种改进的综合型车间物流控制方法。该综合型控制方法融合了看板、鼓-缓冲-绳和固定在制品在不同监控层级的优点,克服了三者在复杂制造环境中各自的不足。基于该控制方法,建立了一套适合于多品种少批量制造环境的车间作业计划系统,并在重庆某企业得到成功应用。

Characteristics of production logistics in a multi-specification and small-batch production environment was studied to realize Just In Time （JIT） lean production. Then, the JIT logistics system was established. Based on analyzing and comparing among Looking Board （KANBAN）, Drum-Buffer-Rope （DBR） and Constant Work In Process （CONWIP）, an improved comprehensive control method on workshop logistics was proposed, which combined the advantages of the foresaid three strategies to overcome shortcomings. Based on the novel control method, the production management system in a multi-specification and small-hatch production environment was established. Finally, application was carried out to validate the feasibility of the improved system.
