Temporary Hubs for the Global Vehicle Supply Chain in Humanitarian Operations

Abstract

W e model the global vehicle supply chain of an International Humanitarian Organization (IHO) with a dynamic hub location model across monthly periods. We use actual vehicle data from the International Federation of the Red Cross to feed our model and provide insights into IHO secondary support demand. We find that secondary support demand for items such as vehicles is different from primary beneficiary demand for items such as water and food. When considering disaster response and development program demand simultaneously (disaster cycle management), our results illustrate that keeping a lean centralized hub configuration with an option for temporary hubs in mega disaster locations can reduce overall supply chain costs over a long time horizon. We also show that it is possible to structure a supply chain to take operational advantage of earmarked funding. This research lays the groundwork for using optimization models to analyze disaster cycle management.

“…Other approaches include that of Kunz et al (2015), who concluded that UNHCR can save costs by centralising its fleet management programme; and that of Jahre and Heigh (2008), who found that a combination of postponement and strategic stocks significantly improves the speed, cost and quality of IFRC's response. Further, Aaki and Pedraza Martinez (2016) and Besiou et al (2014) showed that non-earmarked donations (postponement) improve operational performance; while Stauffer et al (2015) showed how temporary hubs (postponement) for their global fleet gives IFRC an opportunity to use of earmarked funding in a good way. These examples illustrate how combining different SCS may reduce certain risks without increasing others.…”

Defining logistics preparedness: a framework and research agenda

“…An exception is Nooraie and Parast (2016), who modeled the trade-off between increased investment in supply chain capabilities and reduced supply chain risks. Other examples are the studies of fleet management by Pedraza-Martinez et al (2011), Besiou et al (2014), andStauffer et al (2015). Further research could build on their approaches.…”

“…The use of existing resources in the commercial sector has been suggested; for example, 'en route' vessels functioning as sea-based warehouses (Wilberg and Olafsen, 2012). Jahre et al (2016) studied the effect of integrating supply chains for emergencies with those for long-term operations through joint stock prepositioning, while Stauffer et al (2015) and Besiou et al (2015) looked specifically at fleet management. An interesting avenue for future research would be to systematically compare these and other alternatives in various types of situations; for example, using the factors suggested by Kunz and Reiner (2012).…”
