Estudo de roteirização de veículos com apoio de um sistemade informações geográficas: uma contribuição para o transporteurbano de empregados por uma frota de ônibus fretada

摘要

This work aims to develop a procedure for collecting and physical distribution of employees by a fleet of chartered buses with the support of a geographic information system by applying the vehicle routing problem for possible optimization of routes.We begin with a review of the literature on chartered transport of employees, as well as the problems of vehicle routing and geographic information systems. Then wepropose a routing procedure, which characterizes and defines the problem of collection and delivery of employees, in addition to defining the criteria for route ptimization. For this purpose, we use the software TransCAD where you do the modeling and the resolution of the problem. The procedure was applied to a case study in a large company in the Metropolitan Region of Vitória in Espírito Santo State, which provides transport their own to their employees. We generated four scenarios, analyzing the efficiency of the routes in terms of distances, travel times and operating costs. The results generated from the procedure allowed us todetermine in what scenarios the routes are more efficient
