Abstract: The algebra of M-nets, a high-level class of labeled Petri nets, was introduced in the Petri net box calculus in order to cope with the size problem of the low-level nets, especially of applied as semantical domain for parallel programming languages. A general, unrestricted refinement operator, intended to represent the procedure call mechanism for concurrent calls, is introduced into the M-net calculus. Its coherence with the low-level refinements is shown, together with its main properties.
Keywords: M-nets, general refinements, high-level Petri nets.
