R Production Of F Company Proccss Value Stream Study

Since China joined WTO, domestic enterprises have to compete with globally competitive enterprises in the same industries, but how can they deal with this challenge? For now, it is the best choice for Chinese enterprises to make full use of the thought of Lean Production, which aims at updating man’s values and persistently optimizing the process and fully exploring company’s potential. Value Stream Chart (VSC) is a visualizing tool of systematic analysis that can guide people how to find out the problem in a scientific manner and solve it in a systematic manner.From the viewpoint of optimizing production in maximum, and based on theories of VSC, Just In Time, Continuous flow Production, Level pull Production, this essay takes the production lines for R product of F company as an example, and further describes the value flow of the current whole production processes of R product by means of VSC. Besides, combining Value Analysis with IE Flow Analysis, ECRS (Elimination, Combination, Rearrangement, Simplification), it makes a deeper analysis into worthless and wasteful activities in all processes and then figures out the most ideal VCF.Through VA(value analysis), it points out a range of problems, for example, the WIP of R product is often over the normal level, a lot of carrying activities of all process are wasteful, the pre-production activities like line changing are time-consuming, and the production efficiency is low and so on. In terms of the existing problems, this essay displays in detail how management tools are used, such as the Taking Materials By Mark, By-Serials Management, BY-Step Production, Balancing Analysis By Workstation, Linking Production and Swift switch of moulds and lines and Control WIP Level, which effectively eliminates the waste of worthless activities; by6sigma Statistics Summary, and all kinds of graphic analysis and all variables of Inventory, calculate the reasonable levels of the inventory of all processes, which can largely reduce WIP and shorten Pre-production Time; Linking Production can directly eliminates the unnecessary carrying activities between processes, and the whole processes will run in a circulating mode, which will improve VCT(Valuable Cost Time) dramatically and shorten the production completion.Taking the case of R product in F Company for instance, this essay comes up with a series of Action Plans(AP) through value analysis on the whole processes. The APs can not only help the company eliminate waste, improve efficiency, but also provide a reference or a lesson about production process reform and optimizing production for the other enterprises of the group, even for the whole connector industry.
