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：Inspired by the opportunities provided by the Industry 4.0 technologies for smarter, risk-informed, safer, and resilient operation, control, and management of the lifeline critical networks, this study investigates mobility-as-a-service for resilience delivery during natural disasters. Focusing on effective service restoration in power distribution systems, we introduce mobile power sources (MPSs) as the restoration technology of the future, the mobility of which can be harnessed for spatiotem...

摘要：Service contracts are common practice in some industries while being eliminated in others. To investigate this phenomenon, we identify expectation-reality discrepancy (ERD) as a key determinant. A provider's ERD is defined as consumers' ex-ante expected valuation minus their ex-post realized valuation of the provider's service. Our analysis reveals that providers' contract strategies critically depend on their ERDs rather than the true service valuations. A provider with a higher ERD is more l...

摘要：To address the food assistance crisis during the Covid pandemic, the United States Department of Agriculture (USDA) launched a multi-billion dollar Farmers to Families Food Box program (Box program) by working with approved suppliers (or distributors) to purchase fresh produce, dairy, and meat directly from farmers and package them into boxes. Recognizing that food banks did not have spare capacity to support the Box program, how should these food boxes be distributed to people who are in need...

摘要：We partnered with a leading US academic medical center to empirically examine the impact of operational process changes designed to improve preoperative flow of patients through the perioperative environment. We focus on the implementation of centralized decision-making and the introduction of an information technology (IT)-enabled intraoperative prompt, on efficiency, as measured by preoperative patient processing time. We analyze over 33,000 individual surgical cases in a unique field experi...

摘要：Human trafficking, the exploitation of humans for monetary gain or benefit, is a widespread humanitarian issue that is typically sub-classified into labor and sex trafficking. In the last decade, sex traffickers have used online classified advertisements to advertise sexual services. Although these advertisements are visible to the general public and law enforcement, the volume of ads, the frequency with which their posting locale changes, and the use of obfuscation tactics make it difficult f...

摘要：How to avoid project failures driven by overoptimistic schedules? Managers often attempt to mitigate the duration underestimation and improve the accuracy of project schedules by providing their planners with excessively detailed project specifications. While this traditional approach may be intuitive, solely providing more detailed information has proven to have a limited effect on eliminating behavioral biases. We experimentally test the effectiveness of providing detailed specification and ...

摘要：While batch processes are ubiquitous across industries, there is little understanding of the determination of the capacity (i.e., the maximum long-term output rate) of such processes. In this study, we consider processes with collaboration (activities may require multiple resources simultaneously) and multitasking (the same resource may be needed for multiple activities), and characterize the capacity of an arbitrary deterministic, single-product process with batch processing and (activity) se...

摘要：Improving access to family planning services is key to achieving many of the United Nations sustainable development goals. To scale up access in remote areas and urban slums, many developing countries deploy mobile family planning teams that visit outreach sites several times per year. Visit frequencies have a significant effect on the total number of clients served and hence the impact of the outreach program. Using a large dataset of visits in Madagascar, Uganda, and Zimbabwe, our study mode...
