First, we find that KIBS possess good prerequisites to function as vehicles in innovation distribution, the sources of innovation and the facilitators of innovation in their client firms. Second, we further discuss KIBS as the knowledge and innovation infrastructure of society in parallel with the research, educational and other public institutions. Third, we present some research policies and agenda to promote the development of KIBS. It is regarded that much remains to be studied both in the use of KIBS and in their own activities, including integrating and networking the knowledge-intensive services into the client companies, the convergence of various services and closer connection with the client companies' strategy, and the national policies to connect the KIBS to the different sectors.展开更多

Therefore,exploration is required in respect of its business,operations and service provision models. First,an IPTV industry value chain can be formed by integrating the advantages of the existing business models of telecommunication,broadcasting and TV,and Internet industries,which helps realize win-win cooperation of all the parties on the chain. Second,plans for technology implementation and network deployment should be made after comprehensive consideration according to various development stages of the IPTV. Third,a reasonable profit allocation model may promote the growth of IPTV services. Last,market competitiveness will be improved by services bundling. Generally,IPTV will become a breakthrough point for the strategic transformation of telecom operators and meet their innovation demands. Therefore,IPTV is expected to be a promising technology helping telecom operators find more growth space in the information communication market.展开更多

This paper describes how to model Web service composition with CSP. A set of rules for translating composition constructor of Business Process Execution Language for Web Services (BPEL4WS) to CSP notations is defined. According to the rules that have been defined, the corresponding translation algorithm is designed and illustrated with examples . The methods for model checking, model verification and model simulation are also introduced.展开更多

文摘In order to find the roles of knowledge-intensive business services (KIBS) in the innovation activities, This paper focus on three perspectives. First, we find that KIBS possess good prerequisites to function as vehicles in innovation distribution, the sources of innovation and the facilitators of innovation in their client firms. Second, we further discuss KIBS as the knowledge and innovation infrastructure of society in parallel with the research, educational and other public institutions. Third, we present some research policies and agenda to promote the development of KIBS. It is regarded that much remains to be studied both in the use of KIBS and in their own activities, including integrating and networking the knowledge-intensive services into the client companies, the convergence of various services and closer connection with the client companies' strategy, and the national policies to connect the KIBS to the different sectors.
