摘要
选址问题种类繁多,实现的方法和技巧也是多种多样,造成这种多样性的原因主要在于对"最佳位置"的解释,即用什么标准来衡量一个位置的优劣。本文就体育场这一个特殊的设施为例,本着其能为民长远服务的原则,用城市居民到体育场的平均路径最短这一目标建立了体育场的最佳选址模型。与以往不同的是,本文在最短路径算法的基础上,考虑了道路的畅通系数,因此所得的结果更佳。
There are many different kinds of the best site selection problem.Also,there are varied methods and skills for working out this problem.The reason bringing about this diversity is to lie in making an explanation to ＂the best location＂ mainly.In other words,that is which standard would be used to measure a location superior or inferior rank.In this paper,the stadium which is a kind of peculiar facilities is taken for an example,basing on the principle that the stadium can serves people long-term.The best site selection model is established according to the objective that the average route using urban resident to arrive at a stadium is shortest.But the different form the past is that the coefficient of the road hustling degreed is considered on the basis of the shortest-circuit path algorithms in this paper.So the results we got are better.
