“…Only a few quantitative approaches have been proposed in the literature for the procurement in humanitarian relief operations. Emphasized is the work of [10] which describes a tool for decision support MIP (Mixed-Integer Program) in order to improve the maritime carrier and the strategy of bidding prices from the food suppliers, and further the study of [11] which developed decision purchasing models for humanitarian relief. Both works aim at specific situations, in which general guidance for the usage of quantitative methods in relief to assist the procurement of items for relief operations process was not found in the literature.…”

Abstract. The presented approach on this article is related to the task streams activities according to the reference model from humanitarian logistics tasks proposed by Blecken (2009) using the Business Process Modeling Notation (BPMN). Steps were presented initially for the mathematical model insertion, emphasizing on the function of supplies acquisition during the phase of response in case of disasters. The outcome from this model consists on determining which suppliers have the capability to deliver emergency supply items on the requested date. Illustrating the usage of this model, we will show the development of a small example. The first approach contributions is the BPMN specification for assessment tasks and procurement, according to the reference model, including new tasks. The second contribution is represented by a mathematical model insertion, specifically on the task "select supplier", from the reference model. Therefore, there was a graph model proposed for the Network Flow Model, which was adapted to the Humanitarian Logistics context.

Unlike its inherent beneficial attributes, the blood supply chain is very complex due to its uncertain nature and irregular donation besides a high vulnerability to disruptions. In this regard, this study provides a multi‐objective integrated resilient‐efficient model to design a blood supply chain network under uncertainty. To evaluate the efficiency, an augmented form of the data envelopment analysis model is incorporated into the extended model. On the other hand, to improve supply chain resilience, different resiliency measures as optimization tools are introduced and inserted into the considered network. As blood donors have a main role in the blood supply chain, this paper undertakes motivational social aspects to stimulate blood donation for reducing possible shortages. Furthermore, to handle the multi‐objective problem, an interactive fuzzy approach is utilized. Finally, to indicate the applicability of the extended model and its solution approaches, a case study is provided considering realistic data. The results revealed that simultaneously considering all three measures of efficiency, resilience, and cost can assist in improvement of blood supply chain network design and a trade‐off among these three measures can be set by decision maker's preferences.

“…At the same time, it can result in shortages in the local market (if local suppliers do not have the required quantity and quality), local competition between humanitarian organizations, and price inflation (PAHO 2001;Duran et al 2013). International procurement enables access to larger quantities, lower prices, and consistent quality, which is why disaster relief humanitarian procurement is mostly done internationally (Falasca and Zobel 2011). However, this need not be the case with continuous aid.…”

“…Humanitarian logistics activities can be divided into two main categories: immediate disaster relief or long-term continuous aid work, generally following disasters (Falasca and Zobel 2011). The literature on humanitarian logistics is biased towards disaster relief (Venkatesh et al 2014) and focuses primarily on the prepositioning of supplies (Davis et al 2013).…”

“…Procurement for development aid concerns efforts aimed at long-term social and economic development (Taupiac 2001). Within this stream, Falasca and Zobel (2011) introduce a two-stage stochastic programming model for the humanitarian procurement process. Ertem et al (2010) present an auction-based framework for allocating humanitarian procurements, which they evaluate using a simulation model.…”

Purpose While interest in supply chain sustainability has risen over the past few years in academic and business worlds, very little research has been conducted on sustainability in humanitarian supply chains, specifically. This study aims to contribute to the development of the field by conducting a life cycle sustainability analysis (LCSA) of sourcing scenarios for a core relief item in a humanitarian supply chain. Methods This paper is structured according to the LCSA framework developed by Guinée et al. (Environ Sci Technol 45(1):90-96, 2011). The relief item analyzed is a kitchen set supplied by a UN agency. Environmental, social, and economic impacts of two sourcing scenarios for a kitchen set are mapped: one international and one local. Sources of data include interviews, company records, and online databases. Results are analyzed using the ReCiPe method to assess environmental impact and the United Nations Environmental Programme (UNEP)/Society of Environmental Toxicology and Chemistry (SETAC) guidelines to assess social impact.Results and discussion We show how LCSA can be used to map the sustainability of two sourcing scenarios for kitchen sets in a humanitarian supply chain along triple bottom line dimensions. We report findings on sourcing scenarios for distribution to two refugee camps in Kenya: one from a supplier in India and one from a supplier in Kenya. We use an environmental life cycle analysis (LCA), a social LCA, and a life cycle costing (LCC) to analyze differences and similarities. We find that local sourcing is preferred over international sourcing on two out of the three sustainability dimensionsenvironmental and social impacts. Humanitarian organizations may further use this paper as a guideline to develop their own sustainability assessments of supply chain scenarios. Conclusions The results of our study provide a fresh, sustainability-focused perspective on the debate over international vs. local procurement. This paper is the first to apply LCSA to a humanitarian context. It also addresses a void in the sourcing literature by determining the sustainability impacts of different sourcing strategies. The study evaluates only two sourcing options and also uses a limited number of data sources.
