Otimização de custos no transporte coletivo por meio da Programação Linear

Abstract

The activity of transporting oneself is present in the daily life of society, becoming one of its fundamental rights. In this context, many systems have been developed to assist and encourage displacement by the population through urban and rural spaces. However, it is observed that the cost management of these systems needs to be revised and improved since the demands of the consumer market vary over time. This work aims to describe the characteristics of the public bus transport system in the city of Bagé, and to apply Linear Programming as a tool of Operational Research to optimize the allocation of productive resources of one of the companies of the Bagé Public Transport Consortium – CTC. Using LINGO free software, six mathematical models were built, covering three types of hourly programming (working days, Saturdays, and Sundays/Holidays), as well as two different tariff calculation worksheets. As a result, it was obtained a vehicle schedule by time band that allows meeting the passenger demand and minimizing operating costs. It was concluded, therefore, that Operational Research and Linear Programming are appropriate tools to find viable solutions to the problem of public transport and that studies involving other lines can result in many benefits for operators and users of the public transport system of Bagé.
