“…They showed that a significant cost saving benefit may be realized due to the sharing of the substantial fixed cost of such repositioning problem, and the conditions under which such savings may be attained. Adetunji et al [29] also presented a case where there are multiple containers sharing repair facility, the storage space for these containers is limited, and there is the need to balance both the level and the mix of containers made available for shipping and showed the benefit of the shared cost of the repair centre under the space constraint.…”

We present an inventory model to determine the optimal selling price and cycle time for two mutually complementary commodities that are subject to deterioration. Each commodity's demand is influenced by its own selling price, the selling price of the complementary product, and the passage of time. Numerical examples and sensitivity analysis results are presented to demonstrate the usefulness of the inventory model. We conducted sensitivity analysis on the impacts of the changes in key parameters of the model on the decision variables and the objective (profitability) of the inventory system. We observed that as the deterioration rate of either item increases, the model proposes shorter replenishment cycle length, which reduces the profit. Our model's novelty is the inclusion of mutual (twoway) complementarity in the Economic Order Quantity (EOQ) model, where both items are deteriorating and have time-dependent demands.
