Optimizes And Priority Studying Of Highway Project Based On MADM

The investment on highway project is enormous, and with great influence on social economy. So do well network planning, pool arrange properly the road construction scale, overall arrangement and time sequence, that have extremely important meanings to utilizing fund rationally, reducing the economic losses caused by the investment blindly.First introducing the theory that project priority based, have established the theoretical foundation to the index method.Because the factor influencing project construction is numerous, the selected index should have model nature. While on the basis of economic benefits, traffic benefit and environmental benefit heavy, considering from urgency, importance, economic benefits and traffic result,etc. set up the evaluation index system that project priority.Further investigate to decision matrix in theory, putting forward two kinds of new project priority methods:Improved TOPSIS and AHP --Entropy MADM; two kinds of MADM provided hat weight is totally unknown from optimizing the angle most. On the basis of the concrete characteristic of highway project y, set up the optimization model of the investment decision of road construction, consider that leads to the fact the change takes place in actual construction and deadline of the project because of many kinds of factors such as fund, constructing, policy, propose the dynamic adjustment that the project arranges in an order.Finally optimizes and priority studying of highway project based on MADM case analysis to the planned project of the arterial highways network of Jinan.
