摘要:We study capacity planning in the context of Infrastructure as a Service (IaaS) cloud services. Concretely, we propose models for optimal pricing and virtual machine allocation to maximize revenue while maintaining service reliability. Our models are based on current pricing schemes used by predominant cloud services providers in the market. These providers frequently face slack capacity and low utilization in resources, so that they require better planning in the allocation of non-revenue-ear...

摘要:Discrete convexity, in particular,L-convexity andM-convexity, provides a critical opening to attack several classical problems in inventory theory, as well as many other operations problems that arise from more recent practices, for instance, appointment scheduling and bike sharing. As a powerful framework, discrete convex analysis is becoming increasingly popular in the literature. This review will survey the landscape of the approach. We start by introducing several key concepts, namely,L-co...

摘要:We propose a model to assess the value of a distributor in a dynamic stochastic cooperative advertising supply chain in which a manufacturer wholesales its product to a distributor who in turn sells it to a retailer. Moreover and importantly, the distributor also intermediates the pricing and advertising decisions between the manufacturer and the retailer. For the resulting three-player hierarchical game formulation of the supply chain, we characterize the feedback Stackelberg equilibrium in t...

摘要:Public health supply chains are channels through which health commodities are distributed among end clients. In developing countries, significant resource constraints hamper the effective and efficient delivery of health commodities, leading to supply chain failures such as stock-outs. While the prevalence of commodity stock-outs is well-acknowledged, there is little by way of systematic and rigorous empirical research that sheds light on the factors that drive such stock-outs in developing co...

摘要:Although spam email messages have been the primary source of cybercrime since the early Internet era, there is no quick fix to this problem. Governments have established anti-spam legislation, but surprisingly, there has been no measurement of policy impact. This study aims to fill the gap by utilizing a quasi-experimental setting in South Korea, where the anti-spam policy was substantially amended in November 2014. A significant change was in the default setting, switching from an opt-out to ...

摘要:Bundling strategies have been widely adopted by online retail platforms that use agency selling, where suppliers pay a commission fee to the platform to gain access and sell directly to consumers. We study the optimal bundling strategy for a retail platform through which two independent suppliers distribute their products. The suppliers first set their product prices, and, subsequently, the platform decides whether to offer the two products as a bundle and, if so, the price of the bundled prod...

摘要:Using data involving customer-supplier relationships and a large sample of US publicly listed firms, our study documents a negative and statistically significant relationship between economic policy uncertainty and firms' customer-base concentration. The negative relation is predominant in firms with higher inventory efficiency and those operating in competitive, high-R&D, and nondurable industries. Customer-base diversification is further shown to enhance firm performance during periods of in...

摘要:In recent years, the rapid development of online marketplaces has given rise not only to co-opetitive relationships between sellers but also to information asymmetries between online marketplaces and sellers. This study studies information sharing in an e-commerce setting consisting of an online marketplace, an upstream manufacturer and a reseller, where the online marketplace possesses superior demand information, while the manufacturer and reseller engage in a co-opetitive structure. The res...
