Objective
The objectives of the GRADIENT project were to investigate the use of knowledge-based systems to support operators of industrial supervision and control systems, and to enable such operators to conduct an intelligent dialogue with the process, supported by graphical expert systems.
These objectives were to be achieved by building a set of cooperating expert systems which supported a dynamic dialogue. This complex of systems was to be designed to provide the system operator with intelligent support during fault investigation, emergency containment and system modification, as well as during normal operation. The GRADIENT system was intended to be introduced as additional support to be used in parallel with existing supervision and control systems, with a potential of replacing the conventional systems in the future.
A further aim of the project was to assemble KBS demonstrators for use in "hard-tech" industrial environments and to identify appropriate metrication aspects and methods.
The objective of the project were to investigate the use of knowledge based systems to support operators of industrial supervision and control systems, and to enable such operators to conduct an intelligent dialogue with the process, supported by graphical expert systems. The final system is implemented as a number of independent modules cooperating in predefined roles. They include the quick response expert system, responsible for fast reaction to system faults; the response evaluation system, which monitors the operator actions and relates them to procedural plans; the dialogue system, which channels communications between the operator and the system; and the support expert system, which helps the operator in a failure situation. The first version of the intelligent graphical editor was demonstrated in another demonstrator; this is an offline tool for the design of graphics displays. The system integrating all the modules was demonstrated in the context of 2 applications at the final review. These applications are the control of conventional power plants and the control of a communication network. In parallel, a collection of decision support systems for materials and treatment selection in the field of corrosion was demonstrated; studies on metrication aspects have been completed with those systems.
The final GRADIENT system is implemented as a number of independent modules cooperating in predefined roles. These modules have been implemented and demonstrated. In particular, the Quick Response Expert System, responsible for fast reaction to system faults (October 1987); the Response Evaluation System, which monitors the operator actions and relates them to procedural plans (October 1988); the Dialogue System, which channels communications between the operator and the system (October 1988); and the Support Expert System, which helps the operator in a failure situation (April 1990), were initially demonstrated in the context of one demonstrator. In addition, the first version of the Intelligent Graphical Editor was demonstrated in another demonstrator (June 1988); this is an off-line tool for the design of graphics displays. Furthermore, the second version, called IGE2, was demonstrated (November 1989), leading to the IGE3 demonstration (April 1990). The system integrating all the modules was demonstrated in the context of two applications at the final review in October'90. These applications are the control of conventional power plants and the control of a communication network.
In parallel, a collection of decision support systems for materials and treatment selection in the field of corrosion was demonstrated (October 1988); studies on metrication aspects have been completed with those systems.
Exploitation
Two of the system nodules are being further developed for introduction in actual control systems by ABB. This should open the way for introducing more of the advanced ideas developed in GRADIENT in real applications in the future. The network control system will serve as a basis for internal operations for one of CRI's partners. The expert systems for decision support in the field of corrosion are being industrially exploited by DENAC, a subcontractor of KUL. The University of Kassel is trying to commercialise the visual presentation system developed. A prototype was displayed at CeBit.
