Abstract

In this study, an inventory model of pharmaceutical goods that deteriorates or damage to pharmaceutical goods that occurs due to the length of time the goods are stored with an exponential demand rate and considering a quadratic storage rate is formulated. In the optimal solution, the inventory time when it reaches zero (t_1^*) is 0.04568 and the cycle length (T_1^*) is 0.028188 with an average minimum total cost (TC) ̅) of $6378,69 per cycle which is solved with WolframAlpha software. Sensitivity analysis to changes in values resulted in an increase in the value of (TC) ̅ for all parameters except for the D_c parameter which decreased. The increase in the value of α, a and h results in an increase in the value of t_1^* and T_1^* while the value of (TC) ̅ has increased. The increase in the value of θ and s results in an increase in the value of t_1^* and a decrease in the value of T_1^*, while the value of (TC) ̅ increases. Increasing the value D_c results in a decreasing value t_1^* and an increase in the T_1^* value, while the (TC) ̅ value decreases.
