Despite the hype surrounding the value‐added potential of e‐business for contemporary firms, the recent technology downturn was marked by poor customer satisfaction from investment in e‐business initiatives. An apparent mismatch between customer expectations and vendor offerings suggested a lack of appropriate methods and techniques for evaluating e‐business. This article draws from a longitudinal research study on the deployment, hosting and integration of application service provisioning (ASP), an e‐business model targeted mainly at small and medium‐sized businesses (SMBs). Using system dynamics as a methodology that addresses the inherent complexity of the ASP model, the article demonstrates how a series of complex inter‐relationships between key performance indicators (KPIs) will impact the business value for customers from ASP vendor products and services. The lessons from this research will be particularly relevant for existing and future ASP vendors and customers. 相似文献

On the basis of a sample of 184 top executives, we investigated the roles of decision quality and perceived uncertainty in the relationship between decision comprehensiveness and performance. Our results show that decision quality mediates a large proportion of the comprehensiveness–performance relationship and may thus provide a more proximate outcome measure of the effect of comprehensiveness. In addition, we found that perceived uncertainty directly affects the level of comprehensiveness in organizations rather than moderating its effect on performance as conceptualized by previous research. Based on the integration of behavioral and information processing theories we suggest that more process-oriented measures such as decision quality and perceived uncertainty may overcome conflicting empirical results in the field. 相似文献

We generalize Athey's (2001) and McAdams' (2003) results on the existence of monotone pure‐strategy equilibria in Bayesian games. We allow action spaces to be compact locally complete metric semilattices and type spaces to be partially ordered probability spaces. Our proof is based on contractibility rather than convexity of best‐reply sets. Several examples illustrate the scope of the result, including new applications to multi‐unit auctions with risk‐averse bidders. 相似文献

During the past five years, models and techniques developed in artificial intelligence (AI) have been applied to a wide variety
of topics in international relations (IR). These applications build on a theoretical base established at MIT during the 1970s,
and the expansion of the applications reflects both changes in AI research and limitations of alternative models such as statistical
modeling and rational choice approaches. Current applications in IR/AI tend to fall into three categories. First, there have
been extensive applications of if-then rules in expert systems and simulations. Second, many models emphasize the role of
historical precedent in IR decision making. Third, a variety of approaches employing natural language are under development.
These AI techniques have extended considerably the range and complexity of formal models of international behavior.
He has spent the past four years working on applications of artificial intelligence to the problem of making short-term predictions
of international behavior. He is author ofMicrocomputer Methods for Social Scientists (Sage 1987) and numerous articles on mathematical modeling. 相似文献
