Hem güvenilir hem güvenilmez tedarik kanallarıyla bir sağlık problemi envanteri

In this study, we investigate the inventory review policy for a healthcare facility to minimize the impact of inevitable drug shortages when an alternative reliable supplier is present. A continuous-time stochastic process is used to calculate optimal inventory levels for the primary (unreliable) and secondary (reliable but costly) suppliers. We present optimal strategies for tractable instances, provide insights through supervised learning tools, and highlight how these results can be generalized. In particular, we provide business rules for inventory managers that would simultaneously minimize average inventory and secondary supplier usage.
