Problem definition: We examine a dynamic assignment problem faced by a large Wireless Service Provider (WSP) that is a Fortune 100 company. This company manages two warranties: (i) a customer warranty that WSP offers its customers, and (ii) an Original Equipment Manufacturer (OEM) warranty that OEMs offer the WSP. The WSP uses devices refurbished by the OEM as replacement devices and hence their warranty operation is a closed-loop supply chain. Depending on the assignment policy WSP uses, the cu...

Many rigorous flow models have been developed to support the design of manufacturing supply chains. However, supply chains supportive of Access to Medicines (ATM), like vaccine supply chains, impose considerable additional challenges on this design process. The incorporation of a broader base of stakeholders delivers a balanced set of Key Performance Indicators (KPIs) and substantially enhances the societal and human impact of the ATM supply chain service delivery. To evaluate such a set of KPIs...

Abstract In general, vaccines are recognized as an important means to protect populations against infectious diseases. We show that vaccines do not behave like commodity goods and elaborate on the key issues for vaccine supply chain design. This paper reviews the literature on model-based supply chain network design in order to identify the applicability of these models to the key issues of the design of a vaccine supply chain. We study whether the decisions at strategic, tactical and operationa...

Many rigorous models have been developed to support the design of humanitarian supply chains. Supply chains supportive of Access to Medicines (ATM), like vaccine supply chains impose considerable additional challenges on this design process. We embed these models in a broader stakeholder based framework. This will substantially enhance the societal and human impact of the ATM supply chain service delivery. This broader base of stakeholders will deliver a balanced set of Key Performance Indicator...
