摘要：In the last decade, social media platforms have become important communication channels between businesses and consumers. As a result, a lot of consumer-generated data are available online. Unfortunately, they are not fully utilized, partly because of their nature: they are unstructured, subjective, and exist in massive databases. To make use of these data, more than one research method is needed. This study proposes a new, multiple approach to social media data analysis, which counteracts the...

摘要：Past researchers have found evidence that customers consider the sequence of event utility when evaluating past and future service experiences. Specifically, the evidence confirms that the placement of a peak event, the utility of the last event, and the slope of event utility over time all affect customer behavior and perception. We formulate an optimization problem with a focus on optimizing schedule sequence characteristics in order to maximize customer experiences. We discuss possible cont...

摘要：Donors and governments are increasingly calling for more collaborative relationships between humanitarian organizations (HOs), to improve the efficiency and effectiveness of humanitarian operations by exchanging information, knowledge, and resources. This study examines the relative efficacy of partners' characteristics (i.e., compatibility and resource complementarity) and partners' relationship management capability on collaborative relationships, incorporating mutual trust and reciprocal co...

摘要：We extend the Clark-Scarf serial multi-echelon inventory model to include procuring production inputs under short-term take-or-pay contracts at one or more stages. In each period, each such stage has the option to order/process at two different cost rates; the cheaper rate applies to units up to the contract quantity selected in the previous period. We prove that in each period and at each such stage, there are three base-stock levels that characterize an optimal policy, two for the inventory ...

摘要：This study presents the formal problem definition and computational analysis of the network design improvements for idea and message propagation in both enterprise and consumer social networks (ESN and CSN, respectively). Message propagation in social networks is impacted by how messages are seeded in the network, and by propagation characteristics of the network topology itself. It has been recognized that the propagation properties of these networks can be actively influenced by network desi...

摘要：We empirically investigate how time reductions in particular product development stages impact market value. Using longitudinal project data from 107 firms, we compare stage times prior to and following investments in new product development process changes. Our analysis reveals a predominance of focus on time reduction in the late stages of product development. We also find support for the existence of an inverted-U relationship between market performance and time reductions for some of these...

摘要：Service quality is an important attribute that is used to characterize many service systems. In this study, we examine a service system with two consecutive steps that have shared resources. The service process consists of a base service (first step in the process) followed by a second step that adds additional value. We first look at a social surplus maximizing service provider (SP) who decides the optimal service capacity and re-optimizes in response to changes in the speed of service of the...

摘要：In Online Movie Rental Systems, customer desire to rent can often be observed before the actual consumption occurs. Desire represents uncensored (or true) demand information. Hence, the impact of inventory decisions (numbers of physical copies of different movies) can be accurately traced to the creation of desire (via Word-of-mouth), and then to rental. Word-of-Mouth (WOM) has been recognized as one of the most influential sources of information transmission, especially for experience goods. ...

摘要：We study a joint capacity leasing and demand acceptance problem in intermodal transportation. The model features multiple sources of evolving supply and demand, and endogenizes the interplay of three leversforecasting, leasing, and demand acceptance. We characterize the optimal policy, and show how dynamic forecasting coordinates leasing and acceptance. We find (i) the value of dynamic forecasting depends critically on scarcity, stochasticity, and volatility; (ii)traditional mean-value equival...

摘要：Innovation contests are increasingly adopting a format where submissions are viewable by all contestants and the information structure changes during the contest. In such an unblind format, contestants must weigh the costs of revealing their submissions against the benefits of improving their submissions through emerging information. We take a closer look at how contestants solve problems in innovation contests with public submission of solutionsthat is, unblind contests, by examining the impl...
