Research On The Process Optimization For T9 POWER BOX Assembly Of T Company

The economy worldwide has enter into globalization already.There are opportunities also challenges accompanying all the time,and now challenges are becoming even greater.The manufacturing processes represent the functions of transferring raw material into real products,also the manufacturing processes represent the combination of a serial of necessary value added activities.Managers have been always seeking ways to utilize low cost and highly effective output methods to produce products as the main strategy or principle.The thesis started with the researches on problems of T9 POWER BOX assembly,by looking deep into the relevant data,then came up with 3 main problems of the assembly processes that need to solve:high work efficiency,un-balanced workloads,unstable assembly processes.Then,dig out the root causes to 3 main problems,these are:poor management of standard labor hour,inappropriate standard work breakdown and many wastes hiding in the assembly processes.in the end,by utilizing the 4 process analysis principles of IE,standard labor hour management tools of IE and one piece flow of lean production theory to perform a systematic process optimization to the assembly processes.conclusion No.l standard labor hour is very important to the accuracy of efficiency calculation and work performance evaluation,so need to keep it updated according to changes happened to the process constantly.conclusion No.2:to make the work breakdown evenly is the key point to the success of one piece flow production,so need to make the workloads of all work stations even in order to improve line balance.conclusion No.3:it's necessary to run and monitor production processes by using various visual management tools and reducing any abnormalities in order to achieve processes'stabilization.
