Vehicle routing problem thesis

Introduction vehicle routing problem the vehicle routing problem (vrp) is a widely studied combinatorial optimization problem that was introduced — by now half a century ago — in 1959 by dantzig and ramser in [11.

The vehicle routing problem with a volunteer workforce by leonardo mark gala jr a thesis submitted in partial fulfillment of the requirements for the degree of master of. The vehicle routing problem is a combinatorial optimization problem where the ob­ jective function is to minimize total distance under some side constraints solution is a.

The general vehicle routing problem calls for the determination of the optimal set of routes to be performed by a fleet of vehicles to serve a given set of customers. Consider a multiple vehicle routing problem with vehicles with fuel capacities , let denote the set of targets to be visited, and let denote the set of depots that are available. Vii abstract solid waste collection vehicle route optimization for the city of redlands, california by dene l o'connor the city of redlands, california was interested in using a geographic information system.

In the thesis, an application of a genetic algorithm (ga) is considered to solve the vehicle routing problem (vrp) which involves heterogeneous vehicles to serve known customer demands from multiple depots achieving the minimum delivery cost, where each customer must be satisfied by one or more visit(s), and each vehicle must make at most one. In this paper, we present a state-of-the-art survey on the vehicle routing problem with multiple depots (mdvrp) our review considered papers published between 1988 and 2014, in which several variants of the model are studied: time windows, split delivery, heterogeneous fleet, periodic deliveries, and pickup and delivery. This thesis work will concentrate on a very interesting problem, the vehicle routing problem (vrp) in this problem, customers or cities have to be visited and packages.

Stochastic vehicle routing problem: a literature survey eshetie berhan, birhanu beshah† and daniel kitaw‡ school of mechanical and industrial engineering addis ababa institute of technology, addis ababa university. The vehicle routing problem (vrp) is a combinatorial optimization and integer programming problem which asks what is the optimal set of routes for a fleet of vehicles to traverse in order to deliver to a given set of customers. The purpose of this master thesis is to study a yet unexplored aspect of the vehicle routing problem among other things we will look into different meta-heuristics and how they perform on large-scale.

The thesis presents a novel two-phase approach for heterogeneous fleet in vehicle routing problem (vrp) in view of considerable difficulty to solve the class of vrp problem which is indeed np-hard, different types of heuristics methodologies have been employed for the purpose of looking for good solutions which are comparable to optimal solution.
