There is a critical awareness in industry that logic-based and rule-based expert systems are not going to be adequate for the type of complex tasks that typically arise in a wide variety of engineering applications. The main-problem is a lack of standardization concerning parallel implementation of logic programs and rule-based systems. These findings question whether full-scale industrial implementations of intelligent systems should be in these forms. There is consequently a search for alternative symbolic paradigms. The authors have adopted the paradigm of object-orientation in the design, development and implementation of a hardware diagnostic system to demonstrate the potential application of object-oriented expert systems (OBOESs) to a wide variety of industrial problems. One attractive feature of an OBOES is the idea that parallel implementation via distributed object systems becomes feasible.< >

Communications software evolution is conceived as a programmable process, and accordingly supports two interacting data and process models. An object-oriented framework seems necessary to achieve this interaction. The authors summarizes the problem area under investigation, and gives an overview of PVC-M (a process-oriented version and configuration management system)-its objectives, main hypothesis and limitations.< >

Summary form only given. KBO2 (Knowledge-Based object-oriented Environment) is an environment which supports the design and specification of software components and the immediate execution of the specification to examine the component's behaviour. KBO2 is a Prolog system which supports a graphical-based object-oriented component design interface. The graphic design is simply converted into a number of binary argument Prolog predicates which are executed by the Prolog system. The graphical user interface aids rapid specification development and modification.< >

Discusses the IDAS project, a collaborative project investigating and developing an intelligent documentation advisory system (IDAS). The authors' aim is to develop intelligent on-line technical documentation, presented via hypertext with natural language generation and constructed dynamically by expert systems technology using object-oriented techniques. The IDAS being designed is targeted at users of an automatic test equipment (ATE) system and aims to replace part of the current paper-based documentation. The IDAS will represent the ATE using a qualitative model at a level close to linguistic realisation and implemented in an object-oriented framework. It will then display material to the user via a hypertext interface, but where the contents and connectivity of the hypertext nodes are partially determined dynamically according to the system's knowledge of the user's and their goals. In this way, it is hoped to improve on standard hypertext systems, by giving responses which take account of the users problem, skills and privilege.< >

The issue of reverse engineering to an objectoriented representation is examined; a particular contention is whether the objectoriented world of data and associated procedures is a realisable target. It is shown that the problem becomes one of identifying entities which can be encapsulated, rather than the usual one of separating process from data. The requirement for a neural network and rule based mechanism for function extraction is identified. A high level and non-rigorous approach for movement to an objectoriented form is illustrated.< >

HOOD (Hierarchical object-oriented Design) is object-oriented design method which was originally targeted at Ada program development. object-oriented design approaches are based on identifying the classes of objects in a system. Classes are described in terms of their behaviour and structure, with each object modelling a real-world entity. A class and its operations are defined as a single unit. Each object is a member of a class and the operations are defined for all members of a class. The author provides an overview of HOOD and then looks at some case studies of its application at the European Space Agency and Thorn EMI Electronics. He concludes with a general look at its benefits.< >
