Production Inventory Model for Deteriorating Items with Different Deterioration Rates under Stock and Price Dependent Demand and Shortages under Inflation and Permissible Delay in Payments

摘要

A deteriorating items production inventory model with time and price dependent demand under inflation and permissible delay in payments is developed. Different deterioration rates are considered in a cycle. Shortages are allowed. Numerical example is provided to illustrate the model and sensitivity analysis is also carried out for parameters.
