Aplicación de un modelo de programación lineal en la optimización de un sistema de planeación de requerimientos de materiales (MRP) de dos escalones con restricciones de capacidad

a mixed integer linear programming model representing a two-echelon manufacturing system was implemented. optimal decisions could be made about raw material/component provisioning by using the model. the model was programmed by using an algebraic modeller which was then integrated into a computational tool from which defining parameters could be managed as well as consulting the results once the model had been executed. the model was validated on a real manufacturing system; besides providing good representation of the system, optimal provisioning decisions were also reached. the article emphasises that such decisions cannot be made by using usual mrp reasoning.
