Research On Production Decision-making Model In Manufacturing/Remanufacturing Hybrid System Based On Lean Production

In recent years, the huge benefits on economic and environment that remanufacturing can bring attract more and more manufacturers to recycle old items and begin to remanufacture while manufacturing new productions, manufacturing/remanufacturing hybrid system (MRHS) is formed. As remanufacturing process has many uncertainties, however, MRHS is hard to control as well as production decisions are difficult to make. Lean production, as the advanced production management and control tools, shows great superiorities in the adoption of traditional manufacturing system. How to extend the advantages to the uncertain environment of MRHS and make research on production control and decision-making are of grate significance.This paper studies on the MRHS. Considering that not all the customers can accept the remanufactured productions as they accept the manufactured ones, the demand of remanufactured productions are different from the demand of manufactured productions. Compared to the same demand source, researching on production decision-making in different demand sources is of practical significance.The main contents as following:Chapter1, the research on production decision-making of MRHS is shown, problems need to be solved and points need to be improved are discussed also; on the basis of which, the main contents and significance of this paper are presented.Chapter2, the process and characteristics of MRHS are briefly presented and the uncertainties are analyzed in the following; besides, theories about production strategy and production decision-making are basically introduced, lean production as well.Chapter3, the factors that affecting production decision-making are discussed and the special requirements need to be considered before making production decisions are presented; the positive roles that lean production tools play on MRHS are shown, lean production strategy of MRHS based on production substitution are presented as well. Chapter4, based on the presented production strategy, the original production decision-making model of MRHS without production substitution is extended, the model with production substitution based on lean production is developed; the optimal production decisions are solved in mathematical methods.Chapter5, the developed model is applied in multi-period production decision-making of MRHS and the results are gotten by using Matlab, which will be compared with the results of original model.Chapter6, overview and outlook of the research are presented.
