Good management of goods is needed so that the inventory activities of a business can run smoothly as the part of supply chaimanagement which aims to monitor the flow of stock of goods from the purchasing process, and storage to the point of sale. Iterms of inventory or supplies of pharmaceutical goods, conditions such as shortages or stockouts must also be considered which ara matter of control, management, and security. In this study, an inventory model is formulated with deterioration or damage tpharmaceutical goods that occurs due to the length of time when the goods are stored with a linear demand level. In the optimsolution, the inventory time occurs when it reaches the zero point (t1) of 0.34 and the cycle length (T1) of 0.83 with an averagminimum total cost (TC) of 445.25 per cycle which is completed by WolframAlpha software. Sensitivity analysis changes the valuresults in the value of (TC) which that increases for all parameters. In increasing the linear function variables (a and b), it produces tand T1 stable values. An increase in the cost of each item damage (DC) and constant damage rate (θ) produces a t1 stable value, buthe value of T1 increases. The increase in storage costs (h) results in a decrease in the value of t1 and T1. An increase in the cost oshortages (s) results in an increase in the value of t1 and a decrease in the value of T1. © 2024, Magister Program of Material Sciences, Graduate School of Sriwijaya University.
