    A review is presented of reusability and modularity ideas from the software engineering literature, most of which are applicable to the modeling context. Many features of structured modeling support reusability and modularity, and these are noted. The main focus, however, is on achieving reusability and modularity by the integration of two or more model schemas. A five-step approach for integrating schemas written in SML (Structured Modeling Language) is proposed for this purpose. Examples are given to illustrate this approach, and the pros and cons of structured modeling for reuse are discussed at some length View full abstract»

    The authors highlight key differences between previous experimental use of GDSS (group decision support systems) and the previous use of GDSS by business groups, and to discuss the implications that these differences have for researchers in designing future GDSS research. The authors examine previous GDSS laboratory studies and field studies. They then highlight key differences for researchers between these experimental sessions and business group sessions. These differences include organizational context, group characteristics, group size, task, GDSS support, information management needs, and group work process. They discuss two sets of implications for researchers that follow these key differences. First, the need to embark on a synergistic program of research that combines experimental research with field studies is examined. Secondly, the authors present a series of suggestions for enhancing experimental and field study GDSS research View full abstract»

    The authors develop an analytical model for determining the optimal rewriting time. They consider two rewriting strategies involving two different technologies. Several interesting propositions with managerial implications emerge from the analysis. These include the impacts of increasing maintenance requirements and unstructuredness of the technology on the optimal rewriting time, the differences in replacement times for the two technologies, and the effects of system integration requirements on replacement decisions View full abstract»

    The author briefly discusses how GDSS (group decision support systems) have been dealt with in some of the literature to date, arguing that GDSSs are sometimes considered as a single class of systems. He compares four recent GDSS experiments, each conducted at a different university using a different system, to illustrate the differences that exist between design philosophies. The results suggested that GDSSs should not be thought of as a single class of systems. The comparison also illustrates that GDSS researchers are often not investigating the same problem, even though their research is nominally about GDSS, so that they should use caution when they make generalizations about their findings View full abstract»

    A broad discussion is presented of the problems and issues involved in the development of integrated office systems to support higher-level tasks of managers. The authors provide conceptual integration by establishing a framework for the office activities of managers. They discuss the technological integration of disparate office systems through architecture and design of an integrated office information system (IOIS). The IOIS described was developed from the integration of four IOISs at the University of Arizona: the integrated spreadsheet-based inferencing systems (ISBIS); Plexsys planning software (Plexware); the Resource Management Expert (RME); and an intelligent mail system (AIMAIL) View full abstract»

    Heuristics are developed for information scanning activities in large collections of information. These search heuristics are consistent with human information processing behavior identified in prior empirical research. They rely on available knowledge, and provide a guide for the design of computer-based systems which support information scanning. Conclusions are presented which describe how to incorporate time and subjective information profitability into an optimal search strategy, as well as appropriate information to elicit during queries View full abstract»

    Focusing on qualitative reasoning processes as a key area of A1 (artificial intelligence) application for decision support, the authors propose an architecture for designing an intelligent DSS (decision-support system) that is intended to aid in MCDM (multiple-criteria decision making) in ill-structured situations. An MCDM DSS, for its maximum contribution to organizational problem-solving, must be capable of lending effective support to high-level as well as low-level management decisions. A commercial loan approval judgement case is described to illustrate the real-world situation where decisions usually require a high degree of intuition and subjective judgement. Development of a prototype intended to partially represent application of the architecture is described. The authors conclude with suggestions for research extensions View full abstract»

    The statistical consultant described in this paper incorporates a knowledge base in an educational tool for novices in statistical decision-making to use in choosing a statistical technique. The heart of the system is the rule base for differentiating between statistics. The rules are based on five questions which the data can answer, as well as the type of data, the number of variables, and any dependent/independent relationships which exist between the variables. Twenty-nine statistics and the rules for choosing them are in the rule sets. The consultant was tested against the usual textbook method with two different groups of users, 25 undergraduates and 19 doctoral students. The results were that the computer-assisted students in both samples correctly solved a larger proportion of problems despite a conservative test which favored the textbook users and also took longer to find an appropriate solution View full abstract»

    This study investigates the impact that managerial networking knowledge has on the successful use of technologies in firms. A survey primarily of chief executive officers and vice presidents of 30 small manufacturing companies in a tristate region of the Midwest USA was conducted to determine the role that managerial networking knowledge has on (1) the overall number of technologies that a firm introduces and (2) the success rate of technology introduction as measured through usage and overall satisfaction. A mathematical model is constructed and used to analyze the effect of networking knowledge on the probability that an appropriate technology is chosen and used to increase the firm's value. The results of both the survey and the analysis show that managerial competence, defined as networking knowledge, is a critical success factor in technology utilization View full abstract»

    The authors define and differentiate two broad technological support systems for group processes: group decision support systems (GDSS), and group communication support systems (GCSS). They present a framework and method for analyzing the impact of such information systems on groups. They develop the framework from the literature of organization behavior and group psychology and apply it to the literature of management information systems. The authors review and compare empirical research and findings concerned with the impact of GDSS and GCSS on groups. Five major implications stem from the analysis: (a) there is a lack of research on some important formal aspects of groups; (b) there is a paucity of research on the impacts of GDSS and GCSS on the informal dimension of groups; (c) there is a need to move away from laboratory settings to field study in organization settings; (d) more research is needed on the stages in group development and how they affect the impact of GDSS and GCSS; and (e) more research is needed to understand how the structure imposed by the technological supports affect group processes View full abstract»

    An analysis is made of the performance of multiprocessor systems with a multistage interconnection network in the presence of faulty components. Models for estimating the system performance, as measured by its bandwidth and processing power, are developed for two different modes of operation. In the first mode, the operation of the system is fully synchronized and all processors which need memory access issue their requests simultaneously. In the second, each processor is allowed to issue its request at any time instant. For each of the two modes of operation, two models are presented providing lower and upper estimates for the bandwidth of multistage systems. The expected degradation in the performance of the system (in the presence of faulty components) predicted by these two models is then compared to simulation results View full abstract»

    Belief revision in standard rule-based systems is NP-hard, and it is necessary to resort to quasiprobabilistic belief languages which are quite problematic on normative grounds. The author presents a framework designed to study the Bayesian interpretation and cognitive appeal of these languages. He uses this framework to review some well-known and some recent findings, and comments on the merit of alternative approaches to belief revision in rule-based systems View full abstract»

    An alternative representation for modeling organizational procedures is proposed, called event grammars, which is based on the definite-clause grammar formalism used for natural-language parsing. A graphical counterpart, called event nets, is also introduced. In effect, a history of events is recognized as conforming to a particular procedure, analogous to the way in which a list of words is recognized by a particular grammar. Event grammars are intermediate to state transition networks and Petri nets in that they capture contingencies between events but only a limited amount of concurrency. However, considerable compactness of representation is achieved View full abstract»

    The authors describe a heuristic framework for understanding and investigating factors influencing cognitive malleability and, consequently, knowledge acquisition efforts. To examine their framework, they investigated the effects of modifying task materials and goal availability on engineering problem-solving performance and the nature of the knowledge acquired. For one set of four engineers, the dynamic group, any manipulations made by an engineer to a component parameter would be immediately followed by an analysis of the effects of the manipulation. The static group (also four engineers) received no feedback View full abstract»

    Electronic messaging in an office environment is normally carried out in natural language. For a variety of reasons it would be useful if electronic messaging systems could have semantic access to (i.e. access to the meanings and contents of) the messages they process. Given that natural language understanding is not a practicable alternative, there remain three approaches to delivering systems with semantic access: electronic data interchange, tagged messages, and the development of a formal language for business communication (FLBC). The authors compare and contrast these three approaches, present a theoretical basis for an FLBC (speech act theory), and describe a prototype implementation View full abstract»

    A mathematical model is presented for the problem of jointly assigning routes to the communicating pairs of nodes and capacities to the links in a packet-switched network. It is assumed that several classes of flow are using the network, different service requirements and message characteristics being associated with each class. An algorithm that generates good feasible solutions to the model, together with tight lower bounds on the value of the objective function, is presented. Results of numerical experiments using several network topologies are reported View full abstract»
