1、车辆路径规划问题程序设计目的及意义(含国内外的研究现状分析)
我这里只有车辆路径问题的国内外研究现状。。。
2、车辆路径问题的内容简介
《车辆路径问题(影印版)》内容简介:in the field of combinatorial optimization problems, the vehicle routing problem (vrp) is one of the most challenging. defined more than 40 years ago, the problem involves designing the optimal set of routes for fleets of vehicles for the purpose of serving a given set of customers . interest in vrp is motivated by its practical relevance as well as its considerable difficulty.
the vehicle routing problem covers both exact and heuristic methods developed for the vrp and some of its main variants, emphasizing the practical issues common to vrp. the book is composed of three parts containing contributions from well-known experts. the first part covers basic vrp, known more commonly as capacitated vrp. the second part covers three main variants of vrp: with time windows, backhauls, and pickup and delivery. the third part covers issues arising in real-world vrp applications and includes both case studies and references to software packages.
this book will be of interest to both researchers and graate-level students in the communities of operations research and mathematical sciences. it focuses on a specific family of problems while offering a complete overview of the effective use of the most important techniques proposed for the solution of hard combinatorial problems. practitioners will find this book particularly useful.
reader need a basic knowledge of the main methods for the solution of combinatorial optimization problems.
3、车辆路径问题代表的是哪一类的问题
汽车零部件第三方物流业的实际背景,提出了一类新的车辆路径问题,它是一种带时间窗约束的分车运输同时收发车辆路径问题(简称SVRPSPDTW).接着给出了问题的模型,并提出求解问题的启发式算法:两阶段算法.最后在改进的Solomn的算例的基础上,进行了数值试验.
4、车辆行驶路径的二义性是指?
据说是负责把信息写入通行卡里面,表示经过此段高速,这样利于出口计费。所谓“标识站”:确定行驶路径,叠加计算出费额,当路网内出现环路的时候,从入口到出口就会出现不止一条可达路径,即存 在二义性路径。由于无法预知车辆行驶了哪条路径,当然也无法唯一确定如何收 费和拆分结算,现在较常用的解决方法是使用标识站。
5、车辆路径优化
应该是有区别的,三者的侧重点不同。
运输路线优化更侧重:根据运输途径,路线的设计尽可能直线、不重复、短。
配送路线优化更侧重:根据配送点的分布,路线尽可能包囊所有的配送点。
车辆路径优化更侧重:根据车辆的运行,路线尽可能配合车辆,让车辆数量为最少,即一辆车能尽 可能地行驶在各条路线上。
仅供参考。
