An intermodal investment decision model in the transport sector

Transport investment decision-making at government level has acquired special importance in recent years because of rising costs and greater involvement of government in the transport system, especially in developing economies. In the present paper a multiobjective optimization model is presented for intermodal transport investment at the national level and is tested for the Indian transport sector. The novelty of the modeling approach is the combination of a number of single objective linear programming models into a multiobjective goal programming model. An analysis of the LGP results indicate that for the Indian transport sector, the railways and the marine transport systems should receive higher shares of planned investments compared to their current allocations.
