This introduction to intelligent simulation of complex discrete systems and processes - RAO language, focuses on an approach in modelling and simulation of complex systems. In this volume are considered features of complex systems and processes, their mathematical description, and modelling. Theoretical foundations of the RAO (Resource-Action-Operation) language as well as its syntax and utilization are given. Examples of simulation models of different complexity levels, related to different fields, are also presented. The RAO intelligent modelling system, introduced and described in this text is important because: it makes simulation modelling universal for the classes of systems and processes modelled; it is simple to modify the models; and it has the capacity to model complex control systems together with the object controlled (including simulation modelling for on-line control). The RAO tool allows the user to use a language very similar to his professional language and rids him of intermediary, supplementary description of the system modelled.
This volume provides an overview of general modelling trends, and hence serves the research community in guiding their modelling methods; intelligent simulation modelling is introduced to solve complex systems and processes.
