Taking the elevator enterprises as the background,it researches multi-suppliers selection problem in purchasing supplier chain,and establishes multi-objective purchasing optimization model.These objectives contain nine evaluating indicators such as cost,quality,delivery and after-sale service.Based on the multi-objective programming method which uses analytic hierarchy process with an improved ant colony algorithm,it solves the mathematical model to obtain the best supplier choice.Finally it verifes the validity of this method with an example.
