A Trade-Credit Policy for Deteriorating Items with Hybrid Type Demand and Carbon Emission under the Impact of Inflation

In this work, EOQ model develops for decaying items with hybrid demand and green technology under the impact of inflation. Carbon reduction plays a vital role in the green inventory system and in demand which is affected by items price. Moreover, the selling price and green technology investment (GTI) dependent hybrid demand has been considered. Preservation technology (PT) used to control the deterioration of the items. The retailer is allowed distinct period to occupy cash flow by supplier. Transportation and storing inventory process both are the sources of the (CE) carbon emission, and to manage the carbon emission carbon tax regulation considered. Our major goal is to optimize retailer’s selling price, to get maximum total profit, and green technology cost for constant deteriorating items with fixed expiry date. To find the optimal values of the decision parameters, the classical optimization method has been implemented. The optimal values of the total profit function with decision variables as cycle length and selling price are calculated with the help of mathematica-7. For authentication of the results, numerical illustration is done, and concave graphs well present the optimality of the total profit function. Finally, the analysis part carried to show the variations in the parameters.
