||Early hazard identification of chemical plants with statechart modelling techniques
||Oct. 2000, Vol.36, No.1, p.49-67. Illus. 29 ref.
||A comprehensive hazard evaluation of a chemical plant is not only highly recommendable but often subject to official approval of construction by national governmental authorities. Since established methods such as hazard and operability (HazOp) studies are mostly carried out manually and therefore still involve many disadvantages, there has been a marked increase in the research of computer-based analysis methods in the last years. This project aims at introducing a new approach to process hazard identification by simulation and analysis. A qualitative plant model formulated as statecharts has to be generated first despite the lack of information at the early design stages. HazOp-like simulations can then be performed. In addition, special safety issues can be addressed by examining the likelihood of reaching dangerous plant states.
