Abstract

This research formulates an inventory model for pharmaceutical items that deteriorates over time due to their logarithmically changing demand and by considering quadratic storage rates. The optimal solution indicates that when the inventory reaches zero (t_1), the value is 0.00232688 and the cycle length (T_1) is 0.75326 resulting in an average minimum total cost ((TC) ̅) of $530.79 per cycle. The sensitivity analysis results in the value of t_1^* increasing at the value of the damage rate (θ), the variable coefficient t at the demand level (b), and the cost of shortages per item (s) and the value of t_1^* decreasing at the constant value at the demand level (a), the item damage cost (D_c), the storage cost (h), and the variable coefficient t at the storage level (α). The values of T_1^* and (TC) ̅, are stable at the parameters θ, b, h, and α. The value of T_1^* decreases and the value of (TC) ̅ increases at parameters a and s, while the value of T_1^* increases and the value of (TC) ̅ decreases at parameter D_c.
