Expertensystem zur Lastenhefterstellung für die Automatisierung Chemischer Verfahren

Summary

The requirements specification in the process control of chemical productions describes in quality and quantity the objectives and resulting requirements for the system technique to be installed, independant of the system capability. We distinguish between the rough requirements specification (“rough spec”) and the detail requirements specification (“detail spec”) according to the level of detail within the phase of the project model. Also we distinguish between the functional and the project specific requirements specification. The first part of this paper outlines the main items

• structuring of the production facility and its assigned processes

• structuring of the process control functions of the requirements specification in line with it’s generation. Here, the focus is on the area of advanced functionality.

The second part has the purpose to determine how far the technology of expert systems is suitable to support the computerized realization of the requirements specification. To do this a rule-based expert system shell is used to implement a rapid prototype of a partial rough spec on a PC.

Related to the considered problem the discussion shows the advantages of today’s PC-shells, but also discloses their limitations.
