A Research On The Basis Of MOP Theory Of The Vendor Selection Method And Its Demonstration

With the global economic integrity and the development of information technology , the business enterprise faces the more fierce market competition. As a new mode of management, supply chain management (SCM), which can meet the need of global manufacture and various custom demand ,is widely applied in today's enterprise practice .Since the vendor is the upper stream node of the Supply Chain, its selection is the basis of SC's normal functioning, and deeply affects the manufacturer in different ways such as delivery ,quality, advance period, stock level, design and price. For a long time, as a result of the planed economy, evaluation system of supplier selection still hasn't built up properly up to now in our country .Faced to hundreds of suppliers, enterprises always put too much emphases on cost. When there are many supplier bids together, the winner is always the one with lowest price. Such kind of short-sighted behavior emphasized only on cost will inevitably result in the hostility between suppliers and buyers .Accordingly, product quality declined and delivery postponed. Modern Management emphasizes on selecting the suitable supplier strategically and establish a long-term partnership for the purpose of achieving the object of low cost and high quality, flexible production and quick response .Therefore, it is very meaningful to establish a system which can comprehensively and reasonably evaluate and select vendor with the aid of modern management idea and technology. It is also significant to quantitatively make such decision with a method on the basis ofMOP(multiple objective programming) theory.This thesis summarizes the fruits of relevant investigation on supplier selection home and abroad, and designs models on supplier selection decision on the basis of MOP theory and according to the characteristics of the system of the supplier selection decision. At the same time, use these models to carry out several selection objects simultaneously for the purchase decision of the enterprises. The purpose lies in: avoiding the interference of the artificial factor and give a general, concrete and objective evaluation of the supplier to select the right supplier for the sake of strengthening the competition ability of the enterprises.The paper mainly has following research achievements: firstly, analyse the contents and basic procedure of vendor selection on the basis of thorough investigation of the relative literatures; secondly, on the basis of summarization the past vendor selection literatures , draw distillate from the idea of multi-objective programming, combine the multi-objective characteristics of the vendor selection, and design single-item-Multi-plant model, multi-item-single-project model and multi-item-multi-project model respectively, according to the variety of the item purchased and numbers of the plant which need material; finally, on the basis of these MOP models, considering the conditions of a construction company who faces with the vendor selection problem in practice. These models are proved to be a good method in dealing with vendor selection problems ,which are meaningful for improving the management level and competition ability of the company.
