Development of a logistic tool to optimized the milk supply of an agricutural cooperative

This paper discusses the development and implementation of a model for optimizing the milk supply logistics of Cooperativa Agropecuaria Castrolanda, located in the state of Paraná, Brazil. The new logistics are being implemented in response to the restructuring of Brazil's dairy sector and the adoption of bulk milk collection and transportation. The model uses Clark and Wright's economy heuristic, which minimizes the total distance traveled, to represent transportation costs, subject to the constraints of each farm's production volume, tank capacity, and type of truck that can travel on main, secondary and farm roads. The main conclusions to be drawn from this study are the advantages the model offers over current empirical systems and imported commercial models which were originally developed to solve optimization problems in urban environments.
