Maximum-Profit Inventory Model with Generalized Deterioration Rate

We developed a maximum profit inventory model with generalized deterioration rate where the selling is dependent on level that an extension of two published papers. A complete solution structure provided to decide optimal reasonable conditions supported by numerical examples, and then we prove independent demand pattern. Numerical examples are illustrate our findings. In previously paper, three had symmetric local solution. Our approach provides explanation for this phenomenon. findings will help researchers develop new models in future.
