Two basic concepts, SCOPE and SCRIP, were introduced for synthesizing the operating procedures of a chemical plant. A new methodology that mimics the behavior of human operators was developed, along with a computer-based system that evaluates the effectiveness of the methodology.
A plant can be seen as a hierarchical set of subsystems, each of which has particular subfunction that is required for achieving its upper-level function. The upperlevel function can be achieved by realizing all the subfunctions that are subordinate to the upper-level function. Each subsystem is called a SCOPE. The state of the plant at each operation step and the behavior of each subsystem were managed by the SCOPEs.
On the other hand, the heuristic knowledge and operational routine works were generalized by use of the new concept SCRIPT, and were organized in hierarchical form. Two khowledge bases of SCOPEs and SCRIPTs were developed by using the socalled object-oriented approach. SCRIPTs were used as a guideline for synthesizing operating procedures for starting up the plant.
