    Simulation packages traditionally have been developed for the simulation of certain narrow classes of models, such as continuous-time, discrete-time or discrete-event models. In some cases this happened by incorporating simulation possibilities into formerly pure matrix calculation packages, in other cases by designing new programming languages suited for special simulation problems. Combined mode... View full abstract»

  • Deterministic finite capacity automata: a solution to reduce the complexity of modeling and control of automated manufacturing systems

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (584 KB)

    The solution complexity of a synthesized control model of an automated manufacturing system grows exponentially in the number of constituent components in the system (Ho, 1992), thus resulting in the control model being either theoretically untractable in computation (Ramadge, 1989) or practically unfeasible in implementation. By taking advantage of both Petri nets and supervisory control theory, ... View full abstract»

    The design and implementation of a hybrid modelling and simulation strategy is described. The strategy is based on the use of equations, sequential function charts (Grafcets), rules, and object-orientation. This results in a hybrid model base which supports both the hierarchical representation of system structure and the description of the continuous, discrete, and heuristic components of a model....
