摘要: Achieving high dependability of Service-Oriented Architecture (SOA) is crucial for a number emerging and existing critical domains, such as telecommunication, Grid, e-science, e-business, etc. One the possible ways to improve this by employing service redundancy diversity represented component web services with identical or similar functionality at each level composite system hierarchy during composition. Such can clearly reliability (trustworthiness) availability. However apply approach we need solve problems. The paper proposes several solutions ensuring dependable composition when using inherent diversity. We discuss models reflecting different objectives (enhancement availability, responsiveness trustworthiness), invocation strategies redundant (sequential simultaneous) procedures responses adjudication.
