The Research For Replenishment Strategy Of M Company

With the development of the market, the demand of the customers arebecoming more and more diversified, which caused the number of productmodels continues to increase. Production batch is gradually decreasing, and thisis the challenge which many manufacturing companies have to face. On theother hand, labor costs rise continuously, as a result, operation cost of theenterprises continue to rise. This thesis, by optimizing the replenishmentprocesses and establishing new replenishment method for process selection,achieved the purpose of reducing operation costs.There are many kinds of traditional production line replenishment methods,mainly include: batch supply, kanban supply, kitting supply and sequencesupply. But all replenishment methods, no matter kanban supply or batch replenishment is just an option of a way to deliver the parts to production line.However, no one can adapt to all the production situations. They all have theirrespective advantages and disadvantages. How to comprehensively consider allfactors, it is concluded that the optimization of replenishment methods orreplenishment method combination, became the problem the enterprises had toface.Many scholars had made their research in this field. They studied thosereplenishment methods: batch supply, kanban supply, kitting supply andsequence supply. Most of the literature used the internal indicators as a measureof the factory. These indicators include: number of artificial, material types andvolume of the container, material operating times, assembly operation walkingdistance and time, the line space, etc. However, how to consider these factorsor how these factors are integrated into a single index to evaluate thereplenishment system has always been a difficult problem.Which is proposed in this thesis is different from most of the views ofliteratures.it converted the above important evaluation factors into a singleevaluation index-the cost to comprehensive evaluation of replenishmentplanning.This thesis adopts the following analysis. First of all, the wholeprocurement process decomposition for such as the following process, including: material warehousing process, packing process again, shelves,picking processes, distribution and assembly processes. Then, analysis of theabove all the material flow and information flow of the process, record all theartificial cost used with machinery and equipment depreciation, and considerthe cost of space occupied. Then on this basis, application of job analysis, theestablishment of the whole process cost calculation model based on each typeof material. The model can calculate and display the existing productionconditions, arbitrary combination of replenishment method, replenishment costand assembly cost. Finally, adopt the cost calculated by the model as evaluationindex of the replenishment system, and through cost optimization to find theoptimal replenishment planning.Finally, this thesis analyzes the existing replenishment design principle bytaking M company for example, pointed out the shortages of the scheme. Andtwo new methods for replenishment: optimal proportion method and optimalcost method were designed base on the cost calculation model. The optimalproportion method proved the conclusion that the kanban replenishmentmethod has advantages on the cost of replenishment. However, the optimalproportion method also had its limitations. The Optimal cost method couldquantify analyze the influence of different replenishment methods toreplenishment cost, assembly cost and space cost. And also this method could reduce the operation cost by selecting the optimal replenishment methods.
