摘要：Suppliers are increasingly being asked to share information about their vulnerability to climate change and their strategies to reduce greenhouse gas emissions. Their responses vary widely. We theorize and empirically identify several factors associated with suppliers being especially willing to share this information with buyers, focusing on attributes of the buyers seeking this information and of the suppliers being asked to provide it. We test our hypotheses using data from the Carbon Discl...

摘要：In many manufacturing operations, profitable energy efficiency opportunities remain unexploited. Although previous studies have tried to explain the underinvestment, we focus on how the way in which a portfolio of opportunities is presented in a list affects adoption decisions. We use information on over 100,000 energy-saving recommendations made to more than 13,000 small and medium-sized manufacturing firms under the Industrial Assessment Centers program of the U.S. Department of Energy. We f...

摘要：With the recent focus on sustainability, firms making adjustments to their production or distribution capacity levels often have the option of investing in newer technologies with lower carbon footprints and/or energy consumption. These more sustainable technologies typically require a higher up-front investment but have lower operating (fuel or energy) costs. What complicates this decision is the fact that the projected dollar savings from the more sustainable technologies fluctuate considera...

摘要：A common characteristic of basic material manufacturers (which account for 85% of all industrial energy use) and of cleantech manufacturers is that they are price takers in their input and output markets. Variability in those prices has implications for how much a manufacturer should invest in three fundamental types of process improvement. Input price variability reduces the value of improving input efficiency (output produced per unit input) but increases that of capacity efficiency (the rat...

摘要：Modular upgradability has been suggested as a strategy for improving environmental performance: as technology improves, it allows for independent replacement of improving subsystems, instead of replacing the entire product. This may extend the useful life of stable subsystems, reducing production and disposal impact. However, this argument ignores the effect of modular upgradability on a firm's development and introduction decisions and the environmental impact during the use phase. In this pa...

摘要：We use a modified optimal market area model to examine how links between material recycling and other aspects of operations strategy can shape plant networks for the processing of recyclable materials. We characterize the complementarity of the recyclate ratio, defined as the maximum recycled content, with material versatility and miniscaling of recycling plants. We also observe that it is beneficial to coordinate investments in recycling-and production-related competencies because colocated r...

摘要：Paul Kleindorfer was among the first to weigh in on and nurture the stream of sustainable operations management. The thoughts laid out here are based on conversations we had with Paul relating to the drivers underlying sustainability as a management issue: population and per capita consumption growth, the limited nature of resources and sinks, and the responsibility and exposure of firms to ensuing ecological risks and costs. We then discuss how an operations management lens contributes to the...

摘要：Energy generation from intermittent renewable sources introduces additional variability into electrical systems, resulting in a higher cost of balancing against the increased variabilities. Ways to balance demand and supply for electricity include using flexible generation resources, storage operations, and curtailing intermittent generation. This paper focuses on the operational and environmental impact of curtailing intermittent generation. We construct a stochastic dynamic optimization mode...

摘要：We study a nongovernmental organization's (NGO's) decisions when it attempts to remove a potentially hazardous substance from commercial use in a market with competing firms. Specifically, we determine under what market and regulatory conditions an NGO should target the industry versus the regulatory body to influence firms to replace the substance. We examine how the NGO's strategy changes as the NGO's pragmatism (i.e., the extent to which the NGO incorporates firms' profits into its decision...

摘要：T he most widely used standard for mass-casualty triage, START, relies on a fixed-priority ordering among different classes of patients, and does not explicitly consider resource limitations or the changes in survival probabilities with respect to time. We construct a fluid model of patient triage in a mass-casualty incident that incorporates these factors and characterize its optimal policy. We use this characterization to obtain useful insights about the type of simple policies that have a g...
