Özet

This study develops a sustainable inventory model for complementary products by integrating a two-level credit policy with controllable carbon emissions. The model captures key operational complexities such as sustainability-sensitive demand, product interdependence, carbon-cap-and-trade regulations, and deterioration effects. The analysis reveals that offering a coordinated two-level credit period significantly enhances retailer liquidity and stimulates higher demand for both complementary items, thereby increasing overall system profitability. The results show that (i) offering two-level credit enhances retailer profitability and encourages higher-order quantities for complementary goods, (ii) controllable carbon emission investment reduces environmental impact while maintaining cost efficiency, and (iii) joint consideration of credit terms and carbon control creates a win-win scenario for economic and environmental performance. Results further show that investing in carbon-reduction efforts not only lowers total emissions but also reduces regulatory costs under cap-and-trade schemes, leading to economically and environmentally balanced decisions. Sensitivity analysis highlights the critical roles of credit duration, emission-control cost, and deterioration rate in shaping optimal order quantity, carbon-reduction level, and total profit. The findings provide actionable insights for retailers seeking to align financial incentives with sustainable operational strategies while managing interrelated product lines.
