A Study On JC Company Of Production Site To Improve Based On The Theory Of QCD

As China’s national income and living standard enhances unceasingly, Car as a indispensable consumer goods to daily life to gradually enter every ordinary people’ family. Therefore, the domestic automobile industry got the unprecedented development opportunity. Since2009, the annual sales of car in China winning the first that the first time exceed the United States. China winning the first again with the sales volume of19.3million in2012.and won the award for the world’s largest automobile market again.Auto parts market, of course, with the increase of exp-ects sales have increased. The typical representative is the automotive battery industry. At present, China has become the world’s largest production and export car battery, and has apivotal position in the world. however, with the rise of this, and increasingly fierce competition of the industry, multinational companies entering into, and the growing domestic enterprises, and the competition among auto makers to this industry has brought great pressure. So, if a company want to stay forever in such a complex and competitive environment, and get much profit will not be easy. JC multinational company as a typical battery production enterprises, it also faces enormous pressure of competition, how to meet customer requirements under the premise of as much as possible, the maximum reduce production cost, improve product quality,improve the enterprise economic benefit, get more profits will become the biggest problem of JC company now.This paper combined with the production status of JC company, after fully analyzes the JC company’s actual needs, by QCD improvement idea for improving goal-directed, build a theory method system by IE site improve integration, according to the actual circumstance of JC company implemented, and the result of the improvement on the spot, using the fuzzy comprehensive evaluation method of JC company site after improve the comprehensive evaluation of the result and the corresponding conclusions and improvement Suggestions.This thesis studies specific have the following pints:First, build the on-site improvement method based on QCD improvement concept integration system. Analysis from the present situation of JC company, according to its current situation and the problems, performance analysis of the scene of the JC corporation to improve demand. Combined with the theory of QCD improvement ideas and improve the method of comprehensive analysis of the QCD as on-site improvement of goal-directed, contained standardized work, work analysis, work measurement, pulling method, SMED and inventory management to improve methods, such as integration, form a complete suit of JC company site improve the theoretical structure model;Second, the method of improve success implemented in JC company. First, find out its production bottleneck area, production bottlenecks in production line, production bottleneck processes by the JC company production date. For production bottleneck processes, use operation analysis method to find the problem, and standardization of work measurement methods in the post operation; for low production capacity of production line bottleneck problem, adopt the method of SMED, reduce exchange time, increase the production time, increase production capacity; for the problem of low capacity of production area, by the pull method optimized assembly area material distribution methods, using kanban management implement" a flow".Third,using the fuzzy comprehensive evaluation method evaluation to improve results. As one of the paper’s highlights that the JC company field improved results are quantitative evaluation. By QCD (quality, cost, delivery time) as evaluation index level, and build the secondary index that have further influence, form suitable for the JC company improve results evaluation index system, and then evaluate the evaluation mathematical model is set up and draw conclusions.
