Abstract: Because of the complexity in market，there is much imprecise information in selecting financing business for an enterprise，thus hard to make an effective decision.To solve this problem，a quantitative decision making model based on D-S evidence theory is proposed.In this model，different types of information are translated into focal elements in D-S evidence theory.Take profit difference between different financing businesses as the object function，based on evidence reasoning，lower and upper probability distributions of object function are constructed with belief and plausibility functions，thus provide the decision-making basis for the two measures.The simulation results show that，best selection within two financing businesses can be made based on the calculation results of proposed decision model.
