Integrated optimizing model and algorithms of transportation route in out-of-gauge and overweight freights of railway
摘要
Abstract
Through taking transportation route in out-of-gauge and overweight freights of railway as the research object and combining with features of out-of-gauge and overweight freights transportation, this paper bulit the transportation network of out-of-gage and overweight freights with attribute vector and weight vector in arcs. Considered some constraint factors such as section' s gauge, bridge bearing capacity, and balance of traffic flow. Then, taking minimizing interference, transportation mileages and transportation costs as objective functions. It put forward an integrated optimizing model of transportation route in out-of-gauge and overweight freights. And it introduced the two membership functions in order to describe interference quantitatively. On the basis of normalized objective functions with Logistic mode, it structured comprehensive evaluation function with the purpose of converting the multi-objective model into a single-objective model and proved the consistency of models. For solving the model,it devised a kind of heuristic algorithm for searching route and adopted cases matching strategy with revising weights of normalized objective functions continually. The instance demonstrates that the model and algorithms can obtain the reasonable transportation route of out-of-gauge and overweight freights quickly, and meet the requirements for transportation safety.关键词
