The Application Of DAS (Decision Analysis System) In Highway Network Planning

This thesis introduces the application of DAS (Decision Analysis System) in highway network planning. By using DAS, decision-makers can synthetically deal with all kinds of existed data and change non-quantized data or non-quantized index into quantized data or quantized index, thus they can avoid making arbitrary decisions .We will spend more than one decade to build "five vertical and seven horizontal" national highways on the base of national planning. We can bring forward many projects based on different views during highway network planning. But when choosing the most feasible or the best one in all kinds of projects we must analyze and calculate very frequently. We can use multiattribute-decision and multiobject-decision to smoothly solve complex planning problem by the help of combining quantitative analysis and qualitative analysis. The DAS introduced in the thesis utilize the highly mature models of society economics to provide decision-makers with information which is particular direct, entire and exact in virtue of existed resource of large-scale data-base. Thus it can save a lot of time and energy which decision-makers may spend and improve work efficiency.
