• Supply Chain Consequences of Subsidies for Corporate Social Responsibility AI翻译

  摘要：The use of government incentives tied to market prices as means of boosting corporate social responsibility (CSR) has expanded notably in recent decades. Enhanced business tax deductions for charitable donations and credits for conservation easements are notable cases. While providing incentives for socially desirable behavior to achieve legislative goals has intuitive appeal, the broader economic consequences are not always fully understood. In this study, we examine such wider consequences f...
• Positioning Inventory in Clinical Trial Supply Chains AI翻译

  摘要：As a result of slow patient recruitment and high patient costs in the United States, clinical trials are increasingly going global. While recruitment efforts benefit from a larger global footprint, the supply chain has to work harder at getting the right drug supply to the right place at the right time. Certain clinical trial supply chains, especially those supplying biologics, have a combination of unique attributes that have yet to be addressed by existing supply chain models. These attribut...
• Contractors' and Agency Decisions and Policy Implications in A plus B Bidding AI翻译

  摘要：The focus of this study is on the A+B transportation procurement mechanism, which uses the proposed cost (A component) and the proposed time (B component) to score contractors' bids. Empirical studies have shown that this mechanism shortens project durations. We use normative models to study the effect of certain discretionary parameters set by state transportation agencies on contractors' equilibrium bidding strategies, winner selection, and actual completion times. We model the bidding envir...
• Addressing the Challenge of Modeling for Decision-Making in Socially Responsible Operations AI翻译

  摘要：Companies seek sustainability by combining the quest for profitability with the pursuit of social responsibility. Since socially responsible operations are characterized by the presence of multiple stakeholders with conflicting goals, applying classical optimization models would seem premature; we first need to capture the behavior of the entire system before attempting to optimize sub-systems to ensure that we focus on the ones driving the behavior of interest. Alternative methodologies are r...
• Strategic Inventory and Supply Chain Behavior AI翻译

  摘要：Based on a serial supply chain model with two periods and price-sensitive demand, we present the first experimental test of the effect of strategic inventories on supply chain performance. In theory, if holding costs are sufficiently low, the buyer builds up a strategic inventory (even if no operational reasons for stock-holding exist) to limit the supplier's market power, and to increase the own profit share. As it turns out, this enhances the overall supply chain performance. The supplier an...
• Optimal Expediting Policies for a Serial Inventory System with Stochastic Lead Time AI翻译
  作者：Kim, Chiwon; Klabjan, Diego; Simchi-Levi, David

  摘要：In recent supply chains, often operating multiple delivery modes such as standard freight shipping and air is an effective way of addressing both delivery lead time uncertainties and service rates. We propose a model on how to optimally operate multiple delivery modes. We consider a serial supply chain and an expediting option from intermediate installations to the downstream of the chain. The goods move stochastically among the installations and the system faces a stochastic demand. We identi...
• E-Procurement Infusion and Operational Process Impacts in MRO Procurement: Complementary or Substitutive Effects? AI翻译

  摘要：The procurement of maintenance, repair, and operating (MRO) goods has remained a relatively understudied topic in the literature. Though vital cost efficiencies can be extracted from procurement processes through investments in e-procurement systems, there is little empirical work that addresses how such systems should be deployed within organizations. In this study, we focus on the role of e-procurement systems in MRO procurement and study two critical aspects of infusion. The first dimension...

• The Impact of Costliness, Competitive Importance, and Modularity of Investments on Outsourcing AI翻译

  摘要：This study is motivated by examples of outsourcing that are not readily explained by widely established economic theories. We extend recent literature that develops the idea that outsourcing can help firms avoid overinvestment by specifying more precisely the conditions under which this thesis is likely to apply. Our extension is realized through a two-period game theoretic model in which the outsourcing and in-house investments are driven by (1) the cost required to develop a product or proce...
• Does a Store Brand Always Hurt the Manufacturer of a Competing National Brand? AI翻译

  摘要：It is generally believed that store brands hurt the manufacturers of competing national brands while benefiting retailers. In this study, we challenge this notion by studying the impacts of a store brand when it is introduced by a power retailer. We show that a store brand may benefit the manufacturer when the interaction between the manufacturer and retailer is modeled as a retailer-led Stackelberg game. This phenomenon occurs because the store brand changes the nature of the strategic intera...
