Role of time dependent parabolic demand for deteriorating items and time dependent partial back order in an EOQ model of seasonal fruits under intuitionistic fuzzy environment

This study stimulates a major business factor for seasonal retailers and farmers that meet big goals by minimising the total inventory cost of seasonal agro products. At the rising of every season, demands start with shortages, and it takes time to fully filled a prime time. After that, a fresh order is placed to meet demand and deterioration for the remaining time. So, the model designed here stands with its implementation in a manufacturing concern. Here, we introduced an economic order quantity (EOQ) model with a time-dependent parabolic demand and constant deterioration rates, shortages allowed with payment delays, and a partial backorder. For a more realistic feeling, the uncertainty occurs, the model is simultaneously constructed under a crisp and intuitionistic fuzzy environment the trade credit policy up to stock-out time is planned for both cases. The numerical example and the sensitivity analysis have been done for both environments.
