Inventory Models Solved with Hybrid Approaches

摘要

This paper is a further discussion of models with ramp type or trapezoidal type demand. In a previously published paper in European Journal of Operational Research that their solution procedure is accurate, but tedious that will be substituted by our more compact approach to imply a board setting to solve a more general problem. We expand their inventory model from a ramp type demand to an arbitrary demand to reveal a new discovery that the optimal solution is not related to the demand type. Our paper will provide a new trend in inventory models to study new models and solution procedures.
