Brazilian participation in the modern technological process, spread out through globalization, has increasingly demanded changes from companies in order to provide competitiveness. In a dynamic market, like the sector of electronics, characterized by a scenario of a high volatile demand, short products life cycle and strong tendency to fabricate great varieties of products in small volumes (High Mix - Low Volume), therequirements for flexibility of the productive process and low costs are still bigger. It is difficult to define an optimal long term of operations plan which includes preventive maintenance intervention in lines of production. In this dissertation a support model of mathematical programming for the definition of a preventive maintenance schedules in lines of production is developed. The methodology and algorithm were tested on an EMS (Electronic Manufacturing Service) case and the consistency of thesolutions obtained was verified through sensitivity analysis parameter of model.
