TSP - Infrastructure for the Traveling Salesperson Problem

Hahsler, Michael, Hornik, Kurt 12 1900 (has links) (PDF)
The traveling salesperson (or, salesman) problem (TSP) is a well known and important combinatorial optimization problem. The goal is to find the shortest tour that visits each city in a given list exactly once and then returns to the starting city. Despite this simple problem statement, solving the TSP is difficult since it belongs to the class of NP-complete problems. The importance of the TSP arises besides from its theoretical appeal from the variety of its applications. Typical applications in operations research include vehicle routing, computer wiring, cutting wallpaper and job sequencing. The main application in statistics is combinatorial data analysis, e.g., reordering rows and columns of data matrices or identifying clusters. In this paper, we introduce the R package TSP which provides a basic infrastructure for handling and solving the traveling salesperson problem. The package features S3 classes for specifying a TSP and its (possibly optimal) solution as well as several heuristics to find good solutions. In addition, it provides an interface to Concorde, one of the best exact TSP solvers currently available. (authors' abstract)

A localização de facilidades é uma questão central no planejamento estratégico de empresas públicas e privadas e está associada à variação da população em uma região, capital de investimento e estimativa de clientes que podem ser servidos. Este trabalho aborda o problema de localização de facilidades com restrições de capacidade e fonte única para atender a demanda de clientes. A fonte única impõe que um cliente seja atendido por uma única facilidade, e o objetivo é minimizar os custos de instalação e atendimento dos clientes. Este problema tem diversas aplicações, incluindo a localização de concentradores em redes de telecomunicações. Trata-se de um problema complexo de otimização combinatória, em que métodos exatos não produzem uma solução ótima em tempo viável, e portanto o uso de métodos heurísticos é pertinente. O objetivo deste trabalho é o desenvolvimento e implementação de um algoritmo de busca tabu para o problema, e comparação de seu desempenho com outros métodos apresentados na literatura. Palavras-chave: Localização de Facilidades, Otimização Combinatória, Heurística, Busca Tabu / Abstract: Facility location is a logistic problem that involves the decision on the number, location and capacity of facilities to be opened. Facility location is an important area in the strategic planning of public and private companies and is associated with population changes, money availability for investment and the estimation of the number of customers to be served. This work addresses on single source capacitated facility location problem. Single source imposes that each customer must be assigned to only one facility, and the objective is to minimize the installation and transportation costs. This problem has several applications, including the network concentrator location problem. It is a complex combinatorial optimization problem, which cannot be solved by exact methods in small computational times; therefore, heuristics methods are indicated. The objective of this thesis is the development and implementation of a tabu search algorithm for the problem and a comparative analysis with other methods available in the literature.
