Abstract: A representation of interval orders by sequences of antichains is discussed, and its relationship to the Fishburn’s representation by sequences of the beginnings and endings of domain elements is analysed in detail. Moreover, an operational semantics based on sequences of maximal antichains is proposed and investigated for a general class of safe Petri nets with context arcs.

Keywords: interval order, operational semantics, Petri net, sequence of maximal antichains, interval sequence
