摘要
旅行费用与时间是人们出行选择路径时考虑的重要因素。本文讨论了车辆随机路径旅行费用与距离、时间之间的函数关系,在假定旅行费用与距离、时间正相关的条件下,依据矩母函数和 Mason 公式,给出车辆随机路径选择的 GERT 算法,并通过一个应用实例,表明了该算法的有效性。
Travel cost and the time are key problems when people select route. The function relation between stochastic travel cost and the time are studied in this paper. Assuming that travel cost and the time are linearly correlative, the algorithm of GERT model is concluded on the basis of moment generating function and Mason Formula. An example is given to illuminate how to use the algorithm, and the result shows that the method is effective.
