Research On Multi-objective Optimization Decision Methods Of Enterprise Production Equipment Investment Projects

Along with science and technology progress, economic globalization growing enterprise development bring many opportunities, the enterprise faces a growing body of challenging. Enterprise to survive and better development and expansion, they must constantly innovation to adapt to the changing market trends. Increase production investment, improve production decision-making level, is the enterprise improve its competitiveness, and adapt to the development of the situation extremely important ways. Enterprise need to investment projects of scientific and comprehensive evaluation, and then make the right decision.Enterprise production equipment many influencing factors of the investment project, these factors often conflicting with only a single goal, the decision-making often leads to decision error, influence enterprise future survival and development. The existing enterprise production equipment investment decisions tend to focus on economic benefit optimization and reliability analysis, reliability and economic performance is closely related, if can combine the two adopts multi-objective decision-making method for the decision-making, will get more reasonable results.This paper firstly the reliability and economical benefit establish enterprise combining production equipment investment project multi-objective evaluation index system, based on the calculation method for the evaluation index evaluation indexes matrix calculated. Then the entropy weight and policymaker's subjective weight of each index combining determine synthesis weights. Finally in the improvement based on the information entropy comprehensive weight and get combining fuzzy matter-element theory established enterprise production equipment investment project multi-objective synthesis evaluation model. Ultimately, find more reasonable and feasible for enterprise production equipment investment project decision-making.
