Highway Disaster Alignment Decision-making Model Under the Fragile Environment Condition in Mountain Area

Highway disaster alignment is a complex multi-object decision-making problem especially under frail environment conditions such as in mountainous areas. In addition, these objects do not have public characteristics. This paper established the multi-object functional decision making model from the topographic, geologic environmental aspect that may grow and become the cause of all kinds of highway disasters. Using the multi-object decision making theory, this model considered the multi-object forthe highway alignment from the qualitative and quantitative aspect, which has an important academic significance and applied value. In the end of this paper, an example of the analysis is given which indicated the model and its effectivness.
