Abstract :
Currently process algebras have been effectively used for describing and reasoning web services and their composition, but they are lack of cost modeling and analyzing capability and can´t support web services composition with optimal cost. This paper proposes a process algebra called PPA (Priced Process Algebra) basing on CCS (Calculus of Communicating Systems) [1]. We discuss the syntax and semantics of PPA extended with priced information and provide an algorithm to support web services composition with optimal cost.
