The research of emergency rescue optimal path model based on analytic hierarchy process and genetic algorithm

Road attribute data weighting factor lies in the choice of indicators [5]. This article After a lot of literature to read, as well as to verify the actual situation after the accident to determine following four main factors having impact on the emergency evacuation time: (1) Path distance; (2) Road grade; (3) Extent of damage to the road (4) Weather conditions. Weighting factors affecting road have been identified. The hierarchical structure is divided into two layers (Fig. 1), the target layer Z and guidelines layer A. The path weights of the target layer is W; criterion layer for each indicators target layer weights are w1, w2, w3, w4.
