plant simulation model is classified as macroscopic or microscopic. An ERP-level model and a PCS-level model belong to macro and micro simulation model respectively while an MES-level model lies in-between.Simulation models of certain level established by former researchers usually have low reusability and poor scalability.To this end
a novel four-layered approach
which is composed of model entity structure/model base
model abstraction
plant modeling and IPS simulation systems layer
has been proposed for plant modeling and simulation.Configurable and reusable simulation model can be easily obtained by adopting the abstraction modeling and simulation method with respect to plant network. In this article
a multi-level intelligent plant simulation system is constructed with the aforementioned method and the effectiveness and reliability are verified through case studies.Therefore
it is expected to be widely used in plant modeling and simulation in practice.
