【摘要】：随着企业内部和外部经营环境所面临的竞争形势越来越严峻,精益生产方式及其衍生的精益物流等理论方法和技术已成为企业竞争优势的重要源泉。针对具体企业的生产特征,合理、灵活且有效的应用相关方法和技术是企业落实精益思想实现持续发展的关键。本文以断路器产品的车间生产物流系统为研究对象,从生产物流系统的基本理论出发,通过对有关精益生产、精益物流的理论与技术方法及其研究应用情况的总结分析,结合断路器生产车间工艺流程的实际情况及产品、物料的特点,通过运用工业工程5W1H、PCB分析等相关理论方法,挖掘出车间生产物流系统目前存在的关键问题在于现场物料流管理和生产控制的混乱。在此基础上,从车间生产物流系统改善和车间半成品生产供应机制改善两个方面提出详细的改善方案。车间生产物流系统改善主要通过分析物料流现状,收集物料基本信息并进行数据分析以及ABC、XYZ分类,提出合理的物料分类管理策略;更新看板数量并详细设计循环取货(milk run)物料配送系统。车间半成品生产供应机制改善主要针对现有的生产控制方式与供应流程及存在的问题,提出看板生产和按单生产两种方式并设计相对应的存储策略。以上改善方案通过车间的实际应用实施后,不仅达到物料管理清晰合理化、降低车间库存(包括原材料和在制品)水平、优化车间布局、节约车间空间、优化物料存储配送系统、优化车间作业流程的目标,而且相关思路和方法也可以为其他有类似生产状况的车间改善项目提供参考,并扩展延伸到企业整个物流系统。
[Abstract]:With the internal and external business environment facing more and more severe competition situation, lean production mode and its derived lean logistics theory and technology have become an important source of competitive advantage of enterprises. According to the production characteristics of specific enterprises, reasonable, flexible and effective application of relevant methods and technologies is the key to the implementation of lean ideas to achieve sustainable development. In this paper, the workshop production logistics system of circuit breaker products is taken as the research object. Based on the basic theory of production logistics system, this paper summarizes and analyzes the theory and technical methods of lean production, lean logistics and their research and application. According to the actual conditions of the process flow and the characteristics of the products and materials in the circuit breaker workshop, by using the relevant theoretical methods such as industrial engineering 5W1H PCB analysis and so on, The key problem of workshop production logistics system is the chaos of material flow management and production control. On this basis, the improvement scheme is put forward from two aspects: the improvement of workshop production logistics system and the improvement of workshop semi-finished product production and supply mechanism. The improvement of workshop production logistics system is mainly through analyzing the current situation of material flow, collecting the basic information of materials, analyzing the data and classification of ABCX XYZ, and putting forward a reasonable strategy of material classification and management. Update the number of Kanban and design the circulating milk runn material delivery system in detail. In order to improve the production and supply mechanism of semi-finished products in workshop, aiming at the existing production control mode, supply flow and existing problems, the paper puts forward two ways of Kanban production and single production and designs corresponding storage strategies. After the implementation of the above improvement scheme through the practical application of the workshop, not only the material management is clearly rationalized, but also the workshop inventory (including raw materials and in-process products) is reduced, the layout of the workshop is optimized, and the workshop space is saved. Optimization of material storage and distribution system, optimization of workshop job flow, and related ideas and methods can also provide reference for other workshop improvement projects with similar production status, and extend to the whole logistics system of the enterprise.
