Diagnostic goal driven modelling and simulation of multiscale process systems

摘要: A systematic goal-driven top-down modelling methodology is proposed that capable of developing a multiscale model process system for given diagnostic purposes. The goal-set and the symptoms are extracted from HAZOP analysis results, where possible actions to be performed in fault situation also described. dynamic realized form hierarchical coloured Petri net by using novel substitution place-transition pair. Multiscale simulation focuses automatically on areas used predict effect preventive actions. notions procedures illustrated some simple case studies including heat exchanger network more complex wet granulation process.
