【摘要】：WIP－Work In Process,即在制品。是指企业在生产活动过程中处于加工或者等待加工的原材料、零件、半成品或成品，等待的目的是为了投入下一道工序，而最终的目的是为了交付产品，获取利润。在制品在各行业的生产活动中存在于各个环节，其存在的形态由企业所生产产品的工艺和行业特性所决定，可以说，任何产品的生产都需要经过等待制作到制作的过程，因此，存在一定数量的在制品是企业正常生产的客观需求。然而，在制品等待时间过长对于产品的生产周期、生产过程中的生产率、生产效率以及品质的控制均存在很大的影响，从而进一步影响到产品的交付周期，降低企业的竞争力，同时还影响到企业的资金周转。特别是随着市场需求的多样化，小批量多品种的生产方式成为制造行业的主流，如何降低在制品等待时间成为企业生产管理中的核心问题。 G公司是一家生产高档音响产品和专业功放的OEM/ODM混合型港资企业，在生产过程中也存在在制品过多且存在于各个生产环节的问题，对于企业的正常生产活动带来很大的影响。因此，本文将对G公司现阶段生产过程中在制品等待时间的现状进行分析，找出导致在制品等待时间过长的硬制约因素和软制约因素并针对性的提出相应的优化方案并加以实施，最后将生产现场在制品的等待时间在现有基础上减少30%以上，以此提高生产效率和缩短产品生产周期。硬制约因素的分析将结合精益生产的理论和系统性方法，，利用工位平衡法、布局和流程再造、KANBAN、POKAYOKY等精益改善方法，对生产过程中的在制品进行数据分析和优化方案设计并实施。软制约因素的分析将重点研究人员流失率持续居高对在制品等待时间带来的影响以及在制品重点工位激励机制的构建，利用人力资源管理的方法，最大限度减少生产线人员流失以及如何稳定在制品重点工位的人员配置。
[Abstract]:WIP-Work in process, that is, in process. It refers to the raw materials, parts, semi-finished products or finished products that enterprises are processing or waiting for processing in the course of production activities. The purpose of waiting is to invest in the next process, and the ultimate purpose is to deliver the products and obtain profits. WIP exists in all aspects of production activities in various industries, and its form of existence is determined by the technology and industry characteristics of the products produced by enterprises. It can be said that any production of products needs to wait for the process of production to be made, so, The existence of a certain number of WIP is the objective demand of normal production. However, the long waiting time of WIP has a great influence on the production cycle, productivity, efficiency and quality control of the product, thus further affecting the product delivery cycle and reducing the competitiveness of the enterprise. At the same time, it also affects the capital turnover of enterprises. Especially with the diversification of market demand, the production mode of small batch and variety has become the mainstream of the manufacturing industry. How to reduce the waiting time of WIP has become the core problem in the production management of enterprises. G Company is a OEM/ODM hybrid enterprise which produces high-grade audio products and professional amplifier. In the process of production, there are too many in-process products and problems in various production links, which have a great impact on the normal production activities of enterprises. Therefore, this paper will analyze the status quo of the waiting time of in-process products in the production process of G Company at the present stage. Find out the hard and soft restriction factors that lead to the excessive waiting time of the WIP and put forward the corresponding optimization plan and implement it. Finally, the waiting time of the WIP on the production site will be reduced by more than 30% on the existing basis. In order to improve production efficiency and shorten product production cycle. The analysis of hard constraint factors will combine the theory and systematic method of lean production, using the method of work station balance, layout and process reengineering, etc., to carry out the data analysis and optimize the scheme design and implementation of the WIP in the process of production by using the lean improvement methods such as KANBANANPHOKAYOKY, etc. The analysis of soft restriction factors will focus on the impact of the high turnover rate on the waiting time of WIP and the construction of incentive mechanism for the key workstations of WIP, using the method of human resource management. Minimize the loss of production line and how to stabilize the key work in-process staffing.
