MODELLING AND CONTROL OF PROCESS INDUSTRY BATCH PRODUCTION SYSTEMS

摘要

Many models of process industry batch production systems are of a continuous-time/discrete-event (CT/DE) nature: physical processes are modelled using CT specifications, operating procedures are modelled using DE specifications. For scheduling of batch production systems, special purpose tools are available. The Chi language is a CT/DE language with high level DE language elements. This makes it possible to model physical processes using CT and/or DE specifications. It also makes it possible to solve scheduling problems in Chi, and to integrate the scheduler with the model of the batch production systems. The advantages of this approach are illustrated by means of four case studies.
