An economic production quantity (EPQ) model for a deteriorating item with partial trade credit policy for price dependent demand under inflation and reliability

It is well-known that the production-inventory problem for deteriorating items in supply chain a challenge when deciding on how many products to manufacture obtain maximum total profit. This research work develops an economic production quantity model item under partial trade credit policy considering inflation, effect of reliability factor system, and demand depending price product whose selling optimized. The inventory formulated as nonlinearly constrained optimization by analyzing different cases. Finally, through numerical example, sensitivity analysis performed study parameters, changing one parameter at time keeping others fixed their original values.
