摘要:We consider a high-technology supply chain wherein a manufacturer is sourcing a new component from a monopolistic supplier who has limited production capacity. We focus on a setting wherein the manufacturer has decided to adopt the component but has not introduced the end product to the market and the manufacturer's task is to negotiate with the supplier for the procurement price before a deadline. The only uncertainty is the number of manufacturers adopting this component, which determines th...

摘要:As an important domain of disaster management, accident prevention is an urgent and crucial subject because of the high frequency and severe consequences of industrial accidents in recent times. Current researchers focus on organization-level safety antecedents, among which leadership receives the highest attention. However, formal leadership of senior managers is limited by the level-by-level effect attenuation, such that frontline accidents cannot be controlled substantially. Thus, this stud...

摘要:The quality of many online services (such as online games, video streaming, cloud services) depends not only on the service capacity but also on the number of users using the service simultaneously. For a new online service, the potential users are often uncertain about both the capacity and congestion level of the service, and hence are uncertain about the quality of service (QoS). In this study, we consider users' participation-dependent social learning (PDSL), that is, learning of the QoS t...

摘要:A common assumption in the shop scheduling literature is that the processing order of the operations of each job is sequential; however, in practice, there can be multiple connections and finish-to-start dependencies among the operations of each job. This paper studies flexible job shop scheduling problems with arbitrary precedence graphs. Rigorous mixed integer and constraint programming models are presented, as well as an evolutionary algorithm is proposed to solve large-scale problems. The ...

摘要:In this study, we consider the problem of estimating demand functions using historical sales data. In particular, we study how using aggregate data may result in bias in such estimations. We consider a log-log demand model, and two ways of how the price in the aggregate data is calculated, simple average price or weighted average price. We study whether there exists estimation bias in each of the two cases as well as the direction of the bias. We show that in general, the correlation between a...

摘要:We investigate the trade-off between acquisition and retention efforts when customers are sensitive to the quality of service they receive, that is, whether they get timely access to a company's resources when requested. We model the problem as a multi-class queueing network with new and returning customers, time-dependent arrivals, and abandonment. We derive its fluid approximation; a system of ordinary linear differential equations with continuous, piecewise smooth, right-hand sides. Based o...

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:Service contracts are common practice in some industries while being eliminated in others. To investigate this phenomenon, we identify expectation-reality discrepancy (ERD) as a key determinant. A provider's ERD is defined as consumers' ex-ante expected valuation minus their ex-post realized valuation of the provider's service. Our analysis reveals that providers' contract strategies critically depend on their ERDs rather than the true service valuations. A provider with a higher ERD is more l...

摘要:The development of a new drug is costly and uncertain. As such, pharmaceutical firms often collaborate to develop new drugs. We examine the conditions under which firms should collaborate rather than compete in new drug development. We model the collaboration vs. competition decision problem for two firms using a game-theoretic model and derive the collaboration conditions. Our study demonstrates that development cost and uncertainties in drug treatment efficacy and safety and patient enrollme...

摘要:In an election campaign, candidates must decide how to optimally allocate their efforts/resources optimally among the regions of a country. As a result, the outcome of the election will depend on the players' strategies and the voters' preferences. In this work, we present a zero-sum game where two candidates decide how to invest a fixed resource in a set of regions, while considering their sizes and biases. We explore the two voting systems, the Majority System (MS) and the Electoral College ...
