【摘要】：在市场需求多样化，市场竞争日益激烈的今天，制造型企业面对越来越多压力：成本压力、员工流失率高、利润率变低、客户对质量与交货期的要求变高！制造型企业必须提高生产管理水平！精益生产(Lean Production)中的价值流分析正是解决这些问题的有效工具。 精益生产是美国麻省理工学院根据其在“国际汽车项目”研究中，基于对日本丰田生产方式的研究和总结，于1990年提出的制造模式。其核心内容是通过减少供应链环节的各种浪费，达到最低的成本投入与最优质的产品（或服务）产出。精益生产理论中的价值流程图通过分析物料与信息在流程中的流动情况，能对各种生产活动进行增值或不增值的分析研究，并找出各个环节可能的浪费，最终可通过精益生产的有关方法和工具加以改进。 本文以A糖果厂的软糖生产为研究对象，通过市场需求与生产流程的研究，对其物流与信息流等数据进行收集分析，绘制现状价值流程图，挖掘出问题点，，寻找可能的改善机会，并据此设计未来的理想价值流程图。根据识别出来的问题点，以未来的理想价值流程图为指导，以多批少量生产模式、快速换模、看板管理为主要改善思路，制定并实施改善措施。通过改变产品批量，用多批少量的生产模式缩短产品的Lead time，提高最终产品的产出。在快速换模方面，通过识别内外部时间，运用内部时间转外部时间及缩短内部时间的改善思路，对换模时间进行改善；在看板管理方面，用超市补货思路进行拉动式生。运用价值流程图和有关精益生产工具，最终实现整个项目的改善目标。
[Abstract]:In today's market demand diversification and increasingly fierce market competition, manufacturing enterprises are facing more and more pressure: cost pressure, high turnover rate, lower profit rate, higher demand for quality and delivery time! Manufacturing enterprises must improve production management level! The value flow analysis in Lean Production is the solution. An effective tool for solving these problems.
Lean production is based on the research and summary of the production mode of TOYOTA in Japan based on its research on the "international automobile project", based on the research and summary of the production mode of Japanese TOYOTA in 1990. The core content is to reduce the waste of the supply chain and achieve the lowest input and the best quality product (or service) output. By analyzing the flow situation of material and information in the process, the value flow chart in the benefit production theory can analyze the value added or non value-added of various production activities, and find out the possible waste in each link. Finally, it can be improved through the relevant methods and tools of lean production.
This paper takes the production of soft sugar in A candy factory as the research object. Through the research of market demand and production process, we collect and analyze its logistics and information flow data, draw the current value flow chart, dig out the problem points, find the possible improvement opportunities, and design the future ideal value flow chart. According to the identified problem points, Guided by the future ideal value flow chart, a number of production modes, fast changing models, and Kanban management are the main improvement ideas, and the improvement measures are formulated and implemented. By changing the product batch, the Lead time of the product is shortened and the output of the final product is improved by a small number of production modes. Time, the use of internal time to change the external time and shorten the internal time to improve the thinking, to improve the model time; in the management of the Kanban, use the supermarket replenishment ideas for pull students. Use the value flow chart and lean production tools, finally achieve the goal of the whole project.
