Rational Supplier Selection Based on Two-Phase Deep Analysis considering Fuzzy QFD and Game Theory

Viewing from the perspective of a traditional manufacturing enterprise, paper proposes fuzzy comprehensive evaluation system model, which selects most suitable supplier or suppliers to undertake supply tasks and achieve purposes reducing procurement costs improving quality reliability, so as fully meet customer demands. Based on decision-makers’ preferences suppliers’ capabilities, subjective objective weight criteria are both developed for selection with corresponding weighting method, namely, function deployment (QFD) entropy weight. Specially, two-phase QFD method combined trapezoidal number (TFN) is creatively applied realize complicated conversion process. Furthermore, game theory employed combine advantages by can be determined. A numerical example given demonstrate proposed modeling Through programming drawing images comparative analysis sensitivity analysis, study image trends, draw conclusions, model effectively alleviates deviation has higher rationality extensibility in selection.
