摘要：Evaluating and quantifying human suffering in humanitarian operations offers an innovative and potentially powerful way to assess the performance of humanitarian logistics (HL) and help build optimization models. Previous studies have suggested deprivation cost as a metric and have estimated deprivation cost functions for water using willingness-to-pay. Our study proposes deprivation levels, defined as the degree of human suffering caused by lack of access to a good or service, and estimates d...

摘要：We study the funds allocation problem for a resource-constrained non-profit organization (NPO) that implements social development projects for public good. In addition to raising funds from donors who contribute prior to project implementation (traditional donors), the NPO uses a novel approach, which we term as the ex-post funding approach, to also raise funds from donors who contribute based on the results delivered by the NPO (ex-post donors). In this approach, the NPO uses its initial fund...

摘要：The current literature on the coordination of operations and finance does not differentiate long- and short-term debts and therefore is silent on how firms' debt maturity structure affects their short-run financial and operational decisions. Through a dynamic inventory model that explicitly captures a firm's periodic decisions on inventory replenishment quantity, the amount of dividends net of capital subscriptions, and the amount of short-term debt, we demonstrate that under coordinated short...

摘要：In this study, we examine the hospital's ability to admit patients from its emergency department. From a medical perspective, the number of patients being admitted should depend solely on the patients' clinical conditions. Using a large-scale econometric study that includes detailed operational and clinical data on all cardiac patient encounters from a set of 128 hospitals over a period of four years, we show that this is not the case. In particular, we find that independent of their medical c...

摘要：Retailers of perishable goods are often faced with the choice between more expensive packaging that can extend shelf life of their products and less expensive packaging that cannot. Different choices will lead to different sales, costs, and waste, and different choices require different inventory control policies. In this paper, we study the coordination of inventory and packaging decisions in a retailing environment. Items in an active package have a longer lifetime than those in a regular pa...

摘要：Cooperation among humanitarian organizations has attracted increasing attention to enhance effectiveness and efficiency of relief supply chains. Our research focuses on horizontal cooperation in inventory management which is currently implemented in the United Nations Humanitarian Response Depot (UNHRD) network. The present work follows a two-step research approach, which involves collection of empirical data and quantitative modeling to examine and overcome the coordination challenges of the ...

摘要：Despite high demand and resource limitations, humanitarian organizations (HOs) typically do not share resources and/or coordinate in the field. While coordination enhances operational performance and saves costs, the general perception is that it dilutes the media attention that individual organizations might receive, and negatively influences their future donation income. In this study, we empirically unveil the impact of media exposure and operational performance on the donations obtained by...

摘要：We consider a product sold in multiple variants, each with uncertain demand, produced in a multi-stage process from a standard (i.e., generic) sub-assembly. The fan-out point is defined as the last process stage at which outputs are generic (outputs at every subsequent stage are variant-specific). Insights gained from an analytical study of the system are used to develop heuristics that determine the stage(s) at which safety inventory should be held. We offer a relatively-simple heuristic that...

摘要：Past research (along with our experience) suggests that a firm's supply chain (i.e., value chain) plays an integral role in its ability to not only reduce cost via process innovation, but also in its ability to develop new products and services. Evidence suggests the value chain is playing an ever-more-important role, with greater prevalence of distributed product development (spanning geographic, organizational, or firm boundaries) and open innovation (performed outside the firm). We discuss ...

摘要：Motivated by our experience with a global company, we propose and study the concept of a semi-centralized supply chain and analyze its coordination issues. We focus on a supply chain consisting of a home plant and a foreign branch, both of which are under the same parent company but have considerable autonomy. The role of the home plant is to provide a key component to the foreign branch with guaranteed service (required by the headquarters). Because of a high fixed order cost, the branch orde...
