Nesta dissertação aborda-se um importante problema de distribuição logística, o problema da determinação de rotas ótimas designadas na literatura da especialidade por Vehicle Routing Problem (VRP).
Estamos perante um mercado cada vez mais competitivo, em que a satisfação das necessidades dos clientes aparece em primeiro lugar, assim, o tempo de entregas toma especial importância, mas do mesmo modo a otimização de recursos e redução de custos é cada vez mais importante para a sobrevivência das organizações.
Esta dissertação apresenta, num contexto de logística, o problema de otimização de rotas com custos cumulativos, designado na literatura da especialidade por Cumulative Vehicle Routing Problem (CumVRP). Este problema, para além de permitir uma melhor otimização de rotas atendendo aos seus custos num todo, permite também, face a um VRP normal, obter o tempo mínimo de chegada aos clientes. E o problema mais indicado em termos de Logística Humanitária, em que é preciso gerir um conjunto de processos e sistemas envolvidos na mobilização de pessoas, recursos, habilidades e conhecimentos para socorrer vitimas de
desastres, com o objetivo de estabelecer rotas que permitam no menor tempo possível chegar às áreas afetadas afim de poder prestar o socorro necessário.
This dissertation addresses an important problem of logistic distribution, the problem of determination of optimal routes designated in the specialty literature for Vehicle Routing Problem (VRP). We are facing an increasingly competitive market, in which the satisfaction of customers’ needs is vital, thus the delivery time takes special importance, but likewise the resource optimization and cost reduction is increasingly important for the survival of organizations. This dissertation presents, in a context of logistics, the route optimization problem with cumulative costs, designated in the specialty literature by Cumulative Vehicle Routing Problem (CumVRP). This problem, in addition to allow a best route optimization in view of its costs in all, allows, in face of a normal VRP, the minimization of the arrival time to clients. This dissertation presents, in a context of logistics, the route optimization problem with cumulative costs, designated in the specialty literature by Cumulative Vehicle Routing Problem (CumVRP). This problem, in addition to allow a best route optimization in view of its costs in all, allows, in the face of a normal VRP, the minimization of arrival time to clients. Is the most suitable in terms of humanitarian logistics, where is necessary to manage a set of processes and systems involved in mobilizing people, resources, skills and knowledge to assist victims of disasters, with the aim of establishing routes that allow in the shortest time possible to reach the affected areas in order to be able to provide the help necessary.
