摘要：随着中国经济发展变缓慢，房地产不温不火。LB电器的油烟机，燃气灶，消毒柜等厨房电器销量随房地产受到了极大限制。企业之间的竞争日趋激烈，为了更好地将企业经营好，技术创新的同时更要管理创新。为了适应生产环境，必须加大对研发的投入，研发出更好的产品满足消费需求甚至引导消费，从而增加LB电器的市场占有率。与此同时，还应该加强管理。对于大多数制造业来说都存在着生产周期长，库存量大、产品质量不稳定、返工重工多从而生产效率差低下，浪费多。这些问题都可以通过对产品价值流分析，然后根据精益生产的工具去改善生产当中的问题，帮助生产降低成本，减少浪费，加快生产的市场反应速度来帮助企业在众多竞争对手中更具有竞争力，增大利润空间。

通过价值流分析，将LB电器公司的产品从客户订货到采购的定原料再到公司加工生产并将货物运输到客户手中的整个过程进行全面的信息收集然后分析。通过LB电器产品的客户需求，信息流，物流等信息收集绘制的价值流图进行分析，发现生产当中的问题然后设置改善方案，并对改善后的目标绘制未来价值流图。改善的过程当中通过使用IE的七大手法，通过消除八大浪费，线平衡改善，JIT生产等方式使生产变得精益和高效。通过这些改善可以降低LB电器产品生产周期，提高生产效率，降低成本等。

The Research on Improvement of as Company’s Production Process Base on Value Stream Mapping Book Supplier Evaluation

Abstract：With the slow development of China's economy, the real estate is not  warm. LB electric cooker hoods, gas stoves, disinfection cabinets and other kitchen appliances sales with real estate has been greatly limited. The competition between enterprises is becoming more and more fierce. In order to adapt to the production environment, research thereby increasing the market share of LB appliances. These problems can be through the analysis of the value of the product flow, then according to the lean production tools to improve production problems, help production to reduce costs, reduce waste production, accelerate the market reaction speed to help enterprises in the competition more competitive on the hands, to increase profit space.

According to analysis of value flow, LB electrical products from the customers to the procurement of raw materials to manufacture and the whole process of transport of goods to the customer's information collection and comprehensive analysis. In the process of improvement, we can make the production lean and efficient through the elimination of waste, the improvement of the line balance, the JIT production and so on by using the IE's seven methods. Through these improvements can reduce the production cycle of LB electrical products, improve production efficiency, reduce costs, etc..

Keywords: value stream analysis; lean production; line balance improvement; JIT production
