Abstract

Background. The research object is automata models directed to practical use in the field of hierarchical discrete event systems control design with parallel processes. The research subject is hierarchical modular nondeterministic automata (HMNA) based on Vashkevich’s nondeterministic automata. The goal of this work is to develop a concept, a formal definition and tools for discrete event systems control design based on HMNA.
Materials and methods. The research was performed using the set theory, the automata theory and Petri nets.
Results. This paper proposes a concept of HMNA, which is different from the basic concept of nondeterministic automata in the following aspects: a) a possibility of structuring a hierarchical model using the concept of basic and composite automata modules; b) taking into account the short-lived ("pulse") and level signals. Also,
the authors have developed an HMNA modelling method using formalism of netcondition event systems (NCES).
Conclusions. The HMNA concept allows to use the structured approach to designing (e.g., top-down and bottom-up techniques); it increases the descriptive power of automata models and the degree of design artefacts re-use, and extends the scope of automata-approach applicability to discrete event systems designing. Practical usage of the ViVe tool is possible for modeling and analysis of HMNA systems.
