A multiobjective programming approach for selecting non-independent transportation investment alternatives
This article presents a new method for SElecting Non-independent TRansportation investment Alternatives (SENTRA). This method utilizes effective distance heuristic algorithm which attempts to maximize the achieved objectives needed to satisfy available resources. Since transportation investment planning cannot avoid dealing with issues of interdependence among alternatives, this paper will consider four types of investment alternatives: independence, complementarity, substitution and common complementary substitution. Transportation investment alternative selection problem can be formulated in terms of the 0-1 multiobjective multidimensional knapsack problem. Possessing the characteristics of NP-completeness, strict computation is not necessary for the optimal solution, but simple computation for near-optimal solution is expected. The method is proposed in this paper so as to attain the near-optimal solution, which, aside from ranking the selected transportation investment alternatives, can easily perform sensitivity analysis. Finally, an example is presented to illustrate the method.
COOPERATION-COMPETITION MODEL OF TRANSPORTATION CONSTRUCTION PROJECT FROM THE VIEWPOINT OF BUDGET ALLOCATION
ABSTRACT The resource-allocation principle, which combines policy and budget, is the basic criterion for public-policy planning of a government in the present era. It can make the policy target, construction project, and budget work together closely. The transportation construction project has a certain degree of relativity under a target; so when selecting projects, a division of levels should be carried out according to the priority of project desirabilit
