Integrating decisions with advance supply information in an assemble-to-order system

We study a periodic-review assemble-to-order (ATO) system with multiple components and multiple products, in which the inventory replenishment for each component follows an independent base-stock policy and stochastic product demands are satisfied according to a First-Come-First-Served rule. We assume that the replenishment for various component suffers from lead time uncertainty. However, the decision maker has the so-called advance supply information (ASI) associated with the lead times and thus can take advantage of the information for system optimization. We propose a multistage stochastic integer program that incorporates ASI to address the joint optimization of inventory replenishment and component allocation. The optimal base-stock policy for the inventory replenishment is determined using the sample average approximation algorithm. Also, we provide a modified order-based component allocation (MOBCA) heuristic for the component allocation. We additionally consider a special case of the variable lead times where the resulting two-stage stochastic programming model can be characterized as a single-scenario case of the proposed multistage model. We carry out extensive computational studies to quantify the benefits of integrating ASI into joint optimization and to explore the possibility of employing the two-stage model as a relatively efficient approximation scheme for the multistage model.

The correlates of transatlantic burden sharing: revising the agenda for theoretical and policy analysis

While recent work has attempted to update the research agenda for transatiantic defense burden-sharing, there remain significant gaps between the public choice defense economics literature and the security studies literature. The presence of such a gap is unfortunate, because defense spending choices are likely shaped by factors identified by the public choice literature, as well as the strategic and cultural variables that the security studies literature tends to focus on, as well as domestic macroeconomic factors. The independent variables identified in recent qualitative literature are extremely useful analytically, and, fortunately, they have reasonable proxies in available quantitative data, which enables scholars to study them across large groups of countries and many years. This article builds upon such work to synthesize the most notable of the factors identified in the current literature, and offers some common analytical ground that will benefit both scholars and practitioners..
