摘要:Humanitarian operations play a crucial role in alleviating human and social losses caused by natural disasters. The best way to know responders' preparedness and ability to conduct efficient and effective humanitarian operations is to perform an evaluation. When evaluating humanitarian operations, the focus is mainly on their outcomes while the option of concentrating on the process is only mentioned, without examining in-depth the subject nor providing specific tools for its analysis. This st...

摘要:Motivated by the real-world challenges of real options evaluation faced by many companies when commodity prices exhibit dramatic volatility and project values can become negative, this study presents a framework for solving a multifactor real options problem by approximating the underlying stochastic process of project value with a generalized implied binomial tree. The proposed approach allows a flexible structure for stochastic processes with fat tail distributions, such as jump diffusion, r...

摘要:Many manufacturing firms have become increasingly flexible in that they can rapidly idle and restart production in response to changing commodity prices. We study how operational flexibility alters both the timing and financing decisions in the firm. We perform this analysis in a dynamic model in which a firm has multiple debt issues and decisions are made to maximize shareholder value. We compare the decisions of a flexible firm, which can temporarily shut down to avoid operational losses, wi...

摘要:In an election campaign, candidates must decide how to optimally allocate their efforts/resources optimally among the regions of a country. As a result, the outcome of the election will depend on the players' strategies and the voters' preferences. In this work, we present a zero-sum game where two candidates decide how to invest a fixed resource in a set of regions, while considering their sizes and biases. We explore the two voting systems, the Majority System (MS) and the Electoral College ...

摘要:We study the fundamental stochastic newsvendor model that considers both demand and yield randomness. It is usually difficult in practice to describe precisely the joint demand and yield distribution, although partial statistical information and empirical data about this ambiguous distribution are often accessible. We combat the issue of distributional ambiguity by taking a data-driven distributionally robust optimization approach to hedge against all distributions that are sufficiently close ...

摘要:Do humanitarian organizations exhibit similar risk-taking behavior? This study analyzed 60 interviews from 24 case studies on four types of organizations involved in disaster response: established, expanding, extending, and emergent. By elaborating on organizational attention theory, this study investigated how organizational tasks, structures, attention, and context combine to influence organizational risk-taking behavior by different organizational types during sudden-onset disasters. Counte...

摘要:Organizations routinely introduce hitherto-unexplored interventions to improve their supply chains. Consider a principal (e.g., a firm) that implements a seemingly helpful intervention: For any fixed actions of the principal and the agents (e.g., consumers), the principal's payoff is higher in the presence of the intervention than in its absence. While one would expect such well-intentioned interventions to benefit the principal, several papers within the operations management (OM) literature ...

摘要:Given the promise of three-dimensional (3D) printing, also known as additive manufacturing, some innovative consumer goods companies have started to experiment with such a technology for on-demand production. In this study, we consider two adoption cases of 3D printing in a dual-channel (i.e., online and in-store) retail setting, and evaluate its impact on a firm's product offering, pricing, and inventory decisions. Our analysis uncovers the following effects of 3D printing. First, 3D printing...

摘要:One effective means to hedge against uncertainty and better match supply with demand in a swiftly changing environment is to adopt a flexible operations strategy that allows timely response to realized demand. The notion of flexible processes and operations has led to significant impact on the performance of many manufacturing and service applications. However, investing a fully flexible system is usually prohibitively expensive with overwhelming implementation complexity and overhead. As a re...
