Research of multi-objective decision model based on SPA

Multi-objective decision is involved in many fields, an objective, correct and stable validity decision is crucial problem in multi-objective decision. Set Pair Analysis theory is introduced to multi-objective decision model in this paper. The decision scheme is evaluated by using the idea of SPA, and then analyzes the result of decision model by using the idea of difference degree represent uncertainty in SPA theory. This can take the impact of uncertainty information under consideration in the evaluation result. Example shows the effectivity of proposed method and more objective and correct decision can be achieved when the uncertainty information is considered. This method has some directive function for the multi-objective decision.
