Abstract: Environmental degradation is significantly impacted by carbon emissions and deterioration. Real-life demand functions vary, influenced by two distinct demand forms in the market, rather than remaining constant, linear, or nonlinear. This study addresses this complexity by developing a sustainable inventory model for deteriorating items with hybrid-price and stock sensitive demand under a carbon cap and trade policy. Green and preservation techniques are utilised to mitigate excess emissions and deterioration rates. Additionally, the model incorporates the concept of advance payment with a discount facility to accommodate fast-growing businesses. The analysis incorporates the effects of inflation and time-dependent holding costs, allowing for partially backlogged shortages. To validate the model, numerical analyses are conducted for three scenarios based on whether the demand function is hybridised or non-hybridised. Graphical and analytical representations demonstrate the concavity of overall profit, showing that the hybridised demand model yields higher profits compared to the non-hybridised model.

Keywords: inflation; deterioration; preservation technology; green investment; advance payment; hybrid price and stock sensitive demand.
