Özet

This research is concerned with efficient stock management in the context of hospitals. In this regard, the paper aims to classify the medical supplies in public hospitals based on their importance level in the stock control process, and to determine the amount of safety stocks that should be maintained at the beginning of each period. The medical item data was retrieved from the hospital under research and analysed with ABC, VED methods. Results indicate that the demand distributions of the A-V materials represent a normal distribution. The quantity of safety stocks to be obtained at the beginning of periods and the reorder points were calculated using appropriate mathematical equations under assumptions in the probabilistic stock model. Then, total safety stock holding costs were calculated at the determined service levels and cost-based alternative solutions are presented to the decision maker at each service level.
