SAWING PLANNING USING A MULTICRITERIA APPROACH

The lack of integration among the factors involved in the wood sawing planning process creates a gap in the production system and, thus, technical-economic inefficiency in these industries. In this paper we propose a Lexicographic Goal Programming model that enables the consideration of several criteria sequentially; first, production, as traditionally carried out, then performance, and finally appropriate use of the levels of warehoused logs. This multi-objective model is applied to a Cuban sawmill and a metaheuristic method is developed and implemented in order to solve it.
