As the development of Service-oriented architecture and service engineering, they have been generally adopted as the architecture and engineering method of software. More and more service applications and systems are constituted by distributed resources and web services which means more challenges in dynamic, varied and complex network environment. At the same time, the dependence and interactivity between the elements of networked service systems result in faults and difficulties in understanding and upgrading system and making the systems much more weakness. In this paper, according to the dynamic characteristics of the networked service system, we propose a network characteristics measure method and metrics for service system (MSS). Service system is defined by the descriptions of six important parameters at system level, which include service complexity, service cooperation relationship factor, service node factor, service cooperation factor, and service composition factor. Then the corresponding simulation is introduced by using the characteristics measure method and the analysis of the simulation results is also given. At last, a dynamic on-demand service composition algorithm based on MSS is designed and its feasibility and effectiveness are verified.
