    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (416 KB)

    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 i...

    A discussion is presented of a DDS (decision support system) implemented in the highly political environment of a recently acquired division of a Fortune 50 corporation. The system was developed after an assessment of the fund's allocation decision process and was developed for the decision makers rather than with them or by them. The implementation of this DSS relied on at least two distinct bene... View full abstract»

    An analysis is made of three types of transaction-processing systems which support customer feedback in terms of four message system processes, namely: routing, summarizing, delay, and modification. The ability of transaction-processing systems to facilitate intelligent decision-making is seen as a function of the extent to which an organization is able to structure the incoming transactions.

    Parallel savings heuristics are presented for the multicenter tree-network design problem, where the objective is to find the least cost connection between a given set of user and backbone nodes (centers). Each subtree has to satisfy the capacity restriction of the backbone nodes. This approach combines the savings method with the matching problem, and is compared to L.R. Esau and K.C. Williams' (...

    Extends the established relational theory of stored data to encompass logic assertions. Since the truth table for an assertion is a virtual relation, relational database theory can be extended to include assertion management. The author establishes a correspondence between the relational algebra, as applied to the management of stored data, and the same algebra, as applied to the management of log... View full abstract»

    Object-oriented techniques are proposed for applications in computer-integrated manufacturing (CIM). Objects are used to model such manufacturing entities as parts, machines, product structures, and operations. An object-oriented architecture for the product and process design phases of CIM is then proposed. A scenario for simulating the design process is described. It appears that object-oriented...

    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 wi... 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 recog... View full abstract»
