Abstract: Capacity disruptions caused by forces of nature, process-related hazards, and man-made malignant interventions have shown to be a profound risk factor for lean healthcare supply chain systems, such as pharmaceutical and medical equipment/devices enterprises. At the same time, decision support methodologies suitable for analysing healthcare supply chain risk incurred through capacity disruptions have been largely unavailable. In this paper, we examine capacitated healthcare supply chain systems using a framework of feed-forward flow-matching networks with multiple points of delivery. We analyse two models of stochastic dynamics of such systems in the presence of random disruptions. The proposed closed-form analytics will serve as a foundation for future mathematical methodologies for risk-based design of resilient healthcare supply chains.
