Abstract

Climate change is a global challenge that is gaining attention. Reducing carbon emissions is challenging for achieving both economic growth and sustainable development. This study focuses on optimizing profits in an inventory system, accounting for additional costs due to carbon emissions at various process stages. Deterioration and inflation also affect prices and demand over time. To address these real-world complexities, the authors consider demand to be sensitive to both selling price and time, under inflationary conditions. The model incorporates partial backlogging during shortages to maintain a certain level of customer service even when stock is unavailable. A fuzzy approach is employed to handle the unpredictability associated with cost components. Trapezoidal fuzzy numbers are assigned to the cost variables and are defuzzified using the graded mean integration representation method. The fuzzy model shows a 3.82% increase in profit while prices were reduced by 0.27% as compared to the crisp model. The key objective of this model is to maximize profits. Numerical validation and sensitivity analysis are also conducted to evaluate the impact of various changes on the proposed inventory model.
