Critical Situations for Decision Making: A Support Based on a Modelling Tool

This paper proposes to give a toll to help decision makers in critical situations. The principle of our research is based on a modelling approach for Cooperative Knowledge Based Systems. This approach is based on a Task/Method paradigm that we describe. We then propose to take into account collateral effects of tasks in order to support decision makers in a critical context. The proposed tool can then generate a degraded solution for which, collateral effects of previous tasks have been taken as new goals to reach. This study is possible thanks to the definition of several kinds of models: a Good Functioning Model and a Degraded Tasks Library.     

Nonlinear Taylor rules in Central Eastern European countries

This study applies sequential panel selection method (SPSM), proposed by Chortareas and Kapetanios (2009) Chortareas, G., and G. Kapetanios. 2009. “Getting PPP Right: Identifying Mean-Reverting Real Exchange Rates in Panels.” Journal of Banking and Finance 33: 390–404.[Crossref], [Web of Science ®] , [Google Scholar], to investigate to test the validity of Taylor rules to assess the nonstationary properties of the convergence of the real exchange rates for 10 Central Eastern European countries. The SPSM can be used to decompose a panel of real exchange rate series into two groups: a group of stationary series and a group of nonstationary series. We identify the stationary processes in the panel and demonstrate that Taylor rules holds for 7 of the 10 countries studied. These results imply that the choices and effectiveness of the monetary policies in Central Eastern European economies are highly influenced by external factors originating from the United States. Additionally, our findings highlight that their real exchange rate convergence is a mean reversion toward equilibrium values of Taylor rules in a nonlinear manner.

Search reduction in hierarchical distributed problem solving

Knoblock and Korf have determined that abstraction can reduce search at a single agent from exponential to linear complexity (Knoblock 1991; Korf 1987). We extend their results by showing how concurrent problem solving among multiple agents using abstraction can further reduce search to logarithmic complexity. We empirically validate our formal analysis by showing that it correctly predicts performance for the Towers of Hanoi problem (which meets all of the assumptions of the analysis). Furthermore, a powerful form of abstraction for large multiagent systems is to group agents into teams, and teams of agents into larger teams, to form an organizational pyramid. We apply our analysis to such an organization of agents and demonstrate the results in a delivery task domain. Our predictions about abstraction's benefits can also be met in this more realistic domain, even though assumptions made in our analysis are violated. Our analytical results thus hold the promise for explaining in general terms many experimental observations made in specific distributed AI systems, and we demonstrate this ability with examples from prior research.This research has been sponsored, in part, by the National Science Foundation under grants IRI-9015423 and IRI-9010645, by the University of Michigan Rackham Graduate School, and by a Bell Northern Research Postgraduate Award.     

产品生命周期的研究

产品生命周期是指一代产品进入市场后需求存续变化的周期,而不是指需求量、销量波动变化的周期。我们应当研究细分市场的产品生命周期,根据市场某种特性质变的界面来划分产品生命周期的阶段,才更具有营销意义。现行流行的划分产品周期阶段的四种方法。缺乏理论依据,在应用中有较大的随意性。为此,提出了综合判断法,根据多个判据的组合,定位了产品生命周期阶段之间的界面,并提出了对应的营销策略。     

Exploring Electronic Word-of-Mouth (eWOM) in The Consumer Purchase Decision-Making Process: The Case of Online Holidays – Evidence from United Kingdom (UK) Consumers

This study explores the role of electronic word-of-mouth (eWOM) in the consumer decision-making process when purchasing a holiday. Using an ethnographic approach, it explores the role of eWOM on consumers’ attitudes toward online reviews (eReviews) and their subsequent behavior. Across the consumer decision-making processes – information search, evaluation, and purchase – the study develops a conceptual framework with three eWOM dimensions: (1) motivation, (2) source, and (3) content. Findings explore the variations of eWOM’s influence across the decision-making stages with implications for theory and practice. The study further highlights implications for segmentation practices in the tourism industry.
