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

摘要

Highway disaster alignment is a complex multi-object decision-making problem especially under the frail environment conditions such as in mountainous areas, also these objects do not have public characteristics. This paper establishes 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 considers the multi-object about the highway alignment from the qualitative aspect and the quantitative aspect, this has an important academic significance and applied value. In the end of this paper an example analysis is given which indicates the model and its effectivness.
