We argue that the alternative composition operator of CCS not only lacks expressiveness, but also provides a too abstract description of conflicting activities. Hence, we propose to replace it with a unary conflict operator and a conflict restriction operator, yielding the process algebra DiX. We show that DiX is a semantic extension of CCS. Moreover, DiX is equipped with a simple distributed semantics defined in terms of nets with inhibitor arcs, where the set of transitions is generated by three axiom schemata only. This net semantics is the main motivation for the present proposal.
