<p>The paper addressed by the ecofriendly integrated production model to optimize supply chain management under environmental conditions particularly to reduce carbon emission. This model analysis the manufacturer’s and retailer’s optimal production and inventory policies for deteriorating items with variable demand rate. Additionally, preserving the quality of deteriorating goods poses another challenge, requiring effective preservation technology to minimize waste. This model is important as it reflects the modern need for sustainable supply chain solutions that reduce carbon footprints without compromising operational effectiveness or economic viability. The model aims to provide a unique approach integrating preservation technology and carbon emission costs into supply chain decision-making to support environmental responsibility and cost efficiency simultaneously. The solution must address complex interdependencies between demand patterns, deterioration rates, inflation, preservation costs, and emission policies, all while minimizing total costs in a convex optimization framework. This reformulated problem statement focuses on the key supply chain management challenges intertwined with environmental sustainability and preservation of deteriorating goods under economic fluctuations. Hence, this problem is to find an optimal cost policy that balances production efficiency, inventory management, deterioration reduction, cost control including carbon emissions, and environmental sustainability.</p>
