Intelligent support for systems development: The notion and the issues

摘要

Enterprise modelling and information systems modelling have traditionally utilized techniques developed in the earlier disciplines of systems analysis and operational analysis. However, these tools have proved insufficient even for information systems modelling and their inadequacies make them less than ideal for enterprise modelling. Furthermore, it has proved difficult to integrate the techniques into a uniform framework representation. Extensive research since the early 1980s has produced support tools for information systems engineering in the academic sector which have generally failed to reach widespread commercial use. Commercially developed integrated support systems aimed at enterprise modelling and information system modelling use traditional techniques, with a lack of formalism. The purpose of this paper is to introduce a technique which overcomes the major inadequacies and which provides an integrating framework to represent both the information and the processing, at enterprise and systems modelling levels of abstraction. The technique is based on the use of a transition network, but extended to represent enterprise and system models in a meaningful way. The use of an intelligent repository, with associated processing of the formally defined requirements, specification and design statements, is novel, and provides the additional support to make the technique amenable to handling the design process from informal to formal specification. The use of a graphical user interface, linked directly to the deductive system and repository, ensures intuitive ease of use.
