Abstract: The proposed non-instantaneous perishable goods' inventory model emphasises the role of preserving technology investments, selling price, and cycle length in deciding the optimal policy for the inventory model when demand is advertisement, price, and stock-dependent. The model works under the impact of inflation and trade credit. Stocks are backlogged partially with a fixed ratio. Mathematical modelling of the problem is developed, and the nonlinear constrained maximisation problem is solved with the help of classical optimisation techniques by proving some theorems and propositions. Graphs also depict the concavity of the profit function (objective function). Four different cases of delay in payment are taken here separately. A couple of examples are solved to substantiate the proposed algorithm. Sensitivity analysis is established too. Based on the obtained results, the work also takes into account the managerial aspects in deciding the optimality parameters.
