The usual methods of preparedness, such as pre-positioning relief inventory in countries prone to disasters, are problematic because they require high investment in various locations, due to the uncertainty about the timing and location of the next disaster. Investing in disaster management capabilities, such as training staff, pre-negotiating customs agreements with countries prone to disasters, or harmonizing import procedures with local customs clearance procedures, has been recognized as a way to overcome this constraint. By means of system dynamics modeling, we model the delivery process of ready-to-use therapeutic food items during the immediate response phase of a disaster, and we analyze the performance of different preparedness scenarios. We find that pre-positioning inventory produces positive results for the beneficiaries, but at extremely high costs. Investing in disaster management capabilities is an interesting alternative, as it allows lead time reductions of up to 67% (18 days) compared to a scenario without preparedness, at significantly lower costs than pre-positioning inventory. We find that the best performance can be achieved when combining both preparedness strategies, allocating part of the available funding to disaster management capabilities and part to pre-positioning inventory. We analyze 2828 such combined scenarios to identify the best mix of preparedness strategies for different levels of available funding. On the basis of our findings, we provide recommendations for relief organizations on how to allocate their preparedness budget.
- PublicationMétadonnées seulementSustainable business growth in SMEs: How may decision-making guide the transition journey?The research aims at (1) exploring new theory at the interface of business growth and sustainable development while (2) providing managerial implications for growing firms. For this end, we propose typologies of decisions to be considered by growing firms; by means of a longitudinal case study of a Swiss family-owned SME wood construction company (that is in a process of intense growth), we identify, visually represent and analyze the sequences of selected managerial decisions. The empirical analysis and theory development pave novel ways for research and companies towards sustainable business growth.

- PublicationMétadonnées seulementSustainable humanitarian supply chain management – Exploring new theoryWe propose a framework of sustainable humanitarian supply chain management (SCM) for the rehabilitation phase of disasters. Our framework connects enablers, features and triple bottom line performance of SCM with specific socio-economic/governmental contingency factors. Findings from multiple case studies in Chad provide initial evidence for illustrating and underpinning the framework.

However, donors are reluctant to finance such efforts, as there is no certainty that a disaster will strike. Usual methods of preparedness, such as prepositioning of supplies in countries prone to disasters, are problematic because they require high investment costs at various locations, due to the high uncertainty about the timing and location of the next disaster. Product expiry is a major problem, as there is no inventory turnover (Whybark, 2007). Therefore, Van Wassenhove (2006) proposes relief organizations to invest in effective disaster management capabilities, such as human resources, knowledge management, process management, resources and community. Investing in such capabilities instead of physical assets has several benefits. First, in opposition to prepositioning supplies in specific locations, such capabilities acquired by the organization can be used worldwide. Second, these capabilities, in particular those related with import processes, allow organizations to deliver supplies quickly from a central warehouse in case of disaster. Finally, investments in capabilities cost less than prepositioning supplies in large quantities in many locations. In this paper, we analyze the effect of investing in these disaster management capabilities, through a system dynamics model. We model the delivery process of a therapeutic food item during the immediate response phase of a disaster. By comparing a standard import scenario with one where investments in capabilities have been made, we quantify the improvement potential of such preparation efforts (i.e., lead time and inventory reduction). We find that with capabilities investment, goods can be delivered to beneficiaries almost as fast as if supplies were prepositioned in the country, but at lower inventory costs (lower opportunity costs and physical holding costs, less product expiry and obsolescence, etc.). Transportation costs are higher, but occur only where the disaster strikes, and not in each country where inventory is prepositioned. The managerial implication of our research will encourage relief organizations to invest more into capabilities instead of prepositioned physical inventories during the preparedness phase of a disaster. Because of lower costs and risks involved, donors are encouraged to finance such pre-disaster efforts which have a strong potential to improve disaster response.

Furthermore, tradeoffs that probably emerge when aiming at comprehensive multi-dimensional performance are attributed to different supply chain strategy types. Asking why businesses and supply chains still postpone integration of sustainability and other non-financial performance measures into global agrifood supply chains, we point out that these measures represent in fact credence attributes not to be verified by the (final) consumer. This implies the propensity of businesses to engage both in hidden action concerning actual supply chain/operations management and conspicuous public relations. From these considerations we derive some research propositions to be tested in follow-up empirical and modeling/simulation research on global food supply chains.
- PublicationMétadonnées seulementWhat are tradeoffs and obstacles towards a comprehensive framework of supply chain performance in global food chains?Purpose The paper investigates why business still postpones integration of sustainability and other non-financial performance measures into global agrifood supply chains. Design/methodology/approach On basis of literature-based conceptual reasoning (“disciplined imagination”), we identify tradeoffs that are prevalent in basic agrifood supply chain strategy types (efficient, risk-hedging, responsive, and agile chains) and tradeoffs that additionally emerge when agrifood chains simultaneously strive for sustainability. Further, we conceptualize one major obstacle for businesses pursuing comprehensive supply chain performance in global agrifood chains, which helps explaining why agrifood chains procrastinate the integration of sustainability into their business activities. Findings First, we develop a variety of research propositions about performance trade-offs that appear when agrifood chains follow different supply chain strategy types. Second, we point out that many supply chain performance attributes represent in fact credence attributes not to be verified by the (final) consumer. Rational business responses to this situation tend to optimize publicity efforts by sustainability reports and other brand-enhancing marketing tools that are often and easily decoupled from real efforts of operations and supply chain improvements. Research limitations/implications The research propositions are to be tested in follow-up empirical and modeling/simulation research on global food supply chains. Originality/value The conceptual considerations presented in the paper serve as basis for managers and academics to develop innovative inter- and intra-organizational business processes that reconcile tradeoffs pushing the performance frontier outwards and that overcome hurdles towards sustainability that are inherent in current food production, processing, retailing and consumption/shopping practices.
