摘要：Problem definition: The recent surge in demand for cloud services has posed a significant capacity-expansion problem for cloud infrastructure providers. Although the growth of demand for capacity attributes-for example, CPU and RAM-is disproportionate, these attributes are often provided in preconfigured packages (cluster-types), and the fixed ratio of attributes in a package does not match with the time-varying ratio of demand. We analyze a class of expansion policies to determine the timing ...

摘要：Problem definition: This study extends the literature on consumer returns by assessing the impact of return period policy change on a multichannel retailer performance. Academic/practical relevance: Many retailers have recently sought to tighten their return policy by decreasing the return period window. We investigate the impact of such a policy change on sales, returns, and profitability for a multichannel retailer. Methodology: We conduct a multimethodology research in which we (1) develop ...

摘要：Problem definition: To alleviate farmer poverty, governments and nongovernmental organizations (NGOs) are developing different mechanisms for disseminating market information to farmers in developing countries. This paper examines whether a wider dissemination of information will always benefit farmers. Academic/practical relevance: The characterization of the farmers' equilibrium production decisions and the implications of information provision provide practical guidance for governments and ...

摘要：Problem definition: We study a fundamental online resource allocation problem in service operations in which a heterogeneous stream of arrivals that varies in service times and rewards makes service requests from a finite number of servers/providers. This is an online adversarial setting in which nothing more is known about the arrival process of customers. Each server has a finite regular capacity but can be expanded at the expense of overtime cost. Upon arrival of each customer, the system c...

摘要：We study the impact of grocery-store density on the food waste generated at stores and by households. Food waste is a major contributor to carbon emissions (as big as road transport). Identifying and influencing market conditions that can decrease food waste is thus important to combat global warming. We build and calibrate a stylized two-echelon perishable-inventory model to capture grocery purchases and expiration at competing stores and households in a market. We examine how the equilibrium...
