ABSTRACT: The current trend in the chemical process industry is to operate flexible multi-purpose batch plants. This configuration is capable of manufacturing a variety of chemical products using different combinations of available process resources. Flexible and adaptive scheduling is a critical control activity necessary to realize agile manufacturing in a multi-purpose batch plant. In this paper, the real-time scheduling of a multi-purpose batch chemical plant is considered. An adaptive scheduling and control approach, based on predictive control and situation calculus, is developed. Simulation results for the mean flow time using the proposed approach are compared to results obtained using a conventional dispatching rule. Statistical analysis shows that the performance of the proposed approach is preferred for the experimental plant.
