  • An algorithm for weak synthesis observation equivalence for compositional supervisor synthesis

    Mohajerani, Sahar; Malik, Robi; Fabian, Martin (The international Federation of Automatic Control, 2012)
    This paper proposes an algorithm to simplify automata in such a way that compositional synthesis results are preserved in every possible context. It relaxes some requirements of synthesis observation equivalence from ...
  • An algorithm for compositional nonblocking verification of extended finite-state machines

    Mohajerani, Sahar; Malik, Robi; Fabian, Martin (IFAC, 2014)
    This paper describes an approach for compositional nonblocking verification of discrete event systems modelled as extended finite-state machines (EFSM). Previous results about finite-state machines in lock-step synchronisation ...
  • Certainly Unsupervisable States

    Ware, Simon; Malik, Robi; Mohajerani, Sahar; Fabian, Martin (Springer International Publishing, 2014)
    This paper proposes an abstraction method for compositional synthesis. Synthesis is a method to automatically compute a control program or supervisor that restricts the behaviour of a given system to ensure safety and ...
  • Compositional supervisor synthesis with state merging and transition removal

    Mohajerani, Sahar; Malik, Robi; Fabian, Martin (Department of Computer Science, The University of Waikato, 2016)
    This working paper proposes a framework to obtain memory-efficient supervisors for large discrete event systems, which are least restrictive, controllable, and nonblocking. The approach combines compositional synthesis and ...
  • Compositional synthesis of discrete event systems using synthesis abstraction

    Mohajerani, Sahar; Malik, Robi; Ware, Simon; Fabian, Martin (IEEE, 2011)
    This paper proposes a general method to synthesize a least restrictive supervisor for a large discrete event system model, consisting of a large number of arbitrary automata representing the plants and specifications. A ...
