Resumo: The aim of this paper was to propose an application based on the Metaheuristic Tabu Search (TS) to be used on FIELD PREVENTIVE MAINTENANCE SERVICES (FPMS) in order to get more logistics efficiency by routing maintenance sectors. Unlike services performed in industry, where all systems, machines and equipment are located practically in the same location, maintenance services in the field require an additional component directly related to cost, which refers to exactly offset between the base unit and jobsite. Services in the field can be considered a variation of the Travelling Salesman Problem (TSP) and its different approaches, like the DTRP (Dynamic Travelling Repairman Problem) proposed by Bertsimas and Van Ryzin. There is a huge demand for maintenance in the field, demonstrating its relevance: elevators, escalators, electronic devices for home-security, IT hardware support and others. The method was designed, implemented and tested in problems of the TSP-LIBRARY ranging from 17 up to 280 points. Good solutions were found in a acceptable processing time. The input data can be made by geographical coordinates or 2D-coordinates. For a real-world application, it was considered an Elevator Company and the results were also efficient, greatly reducing transportation cost and logistics used in the operation.
