论文摘要

运输是当今社会的重要领域,无论是商业部门还是公民。有不同种类的运输系统,每个系统都有其自身的特征。同样,各个知识领域可以有效地处理运输计划。与运输和物流有关的大多数问题具有共同的特征,因此可以将它们建模为优化问题,能够将它们视为其他通用问题的特殊情况。这些问题适合组合优化字段。这种类型的许多问题具有出色的复杂性。可以找到大量的荟萃分析学,每个文献都有其优势和缺点。由于组合优化问题的复杂性很高,因此没有能够最佳解决所有这些问题的技术。这一事实使组合优化和车辆路线问题的领域成为研究的热门话题。该博士学位论文将集中精力开发一种新的元武器来解决不同类型的车辆路线问题。与现有方法相比,提出的技术与表现有关,以及概念独创性的贡献。为了验证所提出的模型,已将开发的元式元素获得的结果与其他四种相似哲学算法获得的结果进行了比较。在本实验中使用了四个众所周知的路由问题,以及两个经典的组合优化问题。除了基于参数(例如平均值或标准偏差)的比较外,还进行了两种不同的统计检验。得益于这些测试,可以肯定的是,拟议中的元海拔措施在绩效和概念性独创性方面具有竞争力。

Transportation is an essential area in the nowadays society, both for business sector and citizenry. There are different kinds of transportation systems, each one with its own characteristics. In the same way, various areas of knowledge can deal efficiently with the transport planning. The majority of the problems related with the transport and logistics have common characteristics, so they can be modeled as optimization problems, being able to see them as special cases of other generic problems. These problems fit into the combinatorial optimization field. Much of the problems of this type have an exceptional complexity. A great amount of meta-heuristics can be found the literature, each one with its advantages and disadvantages. Due to the high complexity of combinatorial optimization problems, there is no technique able to solve all these problems optimally. This fact makes the fields of combinatorial optimization and vehicle routing problems be a hot topic of research. This doctoral thesis will focus its efforts on developing a new meta-heuristic to solve different kind of vehicle routing problems. The presented technique offers an added value compared to existing methods, either in relation to the performance, and the contribution of conceptual originality. With the aim of validating the proposed model, the results obtained by the developed meta-heuristic have been compared with the ones obtained by other four algorithms of similar philosophy. Four well-known routing problems have been used in this experimentation, as well as two classical combinatorial optimization problems. In addition to the comparisons based on parameters such as the mean, or the standard deviation, two different statistical tests have been carried out. Thanks to these tests it can be affirmed that the proposed meta-heuristic is competitive in terms of performance and conceptual originality.
