Abstract: Inspired by co-evolutionary mechanism in neural-immune-endocrine system, a cytokine network platform was proposed for Web services composition. In the control of cytokine network, bio-entity delegates Web service to construct a Melay evolutionary unit with conditions. Web composition is then transferred to Melay evolutionary process. Bio-entitics construct cytokine network through message matching and conditional constraints to support Web services composition. During the co-evolution process of Web services,the composed services are dynamically adjusted to finish the dynamical composition and management of Web services. The simulation results show that the approach is adaptive in dynamic cnmronmcnts.
