Ordenação de alternativas para suporte às decisões relativas ao transporte intermunicipal e para reduzir o tempo de parada para manutenção

Abstract

There are many problems related to decision-making in the transportation sector, such as logistics, maintenance costs, customer satisfaction and downtime for maintenance, among others. Thus, more research, studies and models need to be developed in order to support decision-making to reduce such problems. This study aims to support decision-making in relation to problems that may arise in the area of public transportation. For decision-makers in the transportation sector, maintenance alternatives are required that can be potentially effective for solving problems in order of priority. In the multi-criteria approach, a model is proposed which offers a ranking for these alternatives in an order of priority through decision-making based on the ELECTRE II outranking method. This model also considers subjective and objective aspects simultaneously, in order to provide decision-makers with a clearer and more comprehensive view, in which the alternatives can address the multiple objectives set by companies. This is done by considering the preferences of decision-makers through focusing on sustainability and economic and environmental aspects. Through this model, it is possible to recognize the orders of priorities to support the management of maintenance, as well as the major potential alternatives to solve problems related to maintenance downtime that affect intercity buses. This study discusses the results of an application of this model within a public transportation company in Brazil.
