摘要：A large number of studies have been conducted during the last decade and a half attempting to identify those factors that contribute to information systems success. However, the dependent variable in these studies I/S success has been an elusive one to define. Different researchers have addressed different aspects of success, making comparisons difficult and the prospect of building a cumulative tradition for I/S research similarly elusive. To organize this diverse research, as well as to pres...

摘要：The optimal amount of information needed in a given decision-making situation lies somewhere along a continuum from not enough to too much. Ackoff proposed that information systems often hinder the decision-making process by creating information overload. To deal with this problem, he called for systems that could filter and condense data so that only relevant information reached the decision maker. The potential for information overload is especially critical in text-based information. The pu...

摘要：Development of large-scale models often involves or, certainly could benefit from linking existing models. This process is termed model integration and involves two related aspects: (1) the coupling of model representations, and (2) the coupling of the processes for evaluating, or executing, instances of these representations. Given this distinction, we overview model integration capabilities in existing executable modeling languages, discuss current theoretical approaches to model integration...

摘要：This paper defines an information system design theory (ISDT) to be a prescriptive theory which integrates normative and descriptive theories into design paths intended to produce more effective information systems. The nature of ISDTs is articulated using Dubin's concept of theory building and Simon's idea of a science of the artificial. An example of an ISDT is presented in the context of Executive Information Systems (EIS). Despite the increasing awareness of the potential of EIS for enhanc...
