Abstract EN
Dynamic selection and dynamic binding and rebinding at runtime are new characters of composite services.
The traditional static reliability prediction models are unsuitable to dynamic composite services.
A new reliability predicting algorithm for composite services is proposed in this paper.
Firstly, a composite service is decomposed into composition unites (executing path, composite module and atomic service) according to their constituents.
Consequently, a hierarchical graph of all composite units is constructed.
Lastly, a new dynamic reliability prediction algorithm is presented.
Comparing with the traditional reliability model, the new dynamic reliability approach is more flexible, which does not recompute reliability for all composite units and only computes the reliability of the effected composite units.
In addition, an example to show how to measure the reliability based on our algorithm is designed.
The experimental results show our proposed methods can give an accurate estimation of reliability.
Furthermore, a more flexible sensitivity analysis is performed to determine which service component has the most significant impact on the improvement of composite service reliability.
