In the cloud computing environment, more and more functional-equivalent services are provided with different QoS levels by competitive provider, resulting to increasing importance of QoS-based service selection or recommendation. To cope with this multi-objective optimization problem, we first propose a novel improved k-dominance operator, i.e. the partial dominance score. By combining the partial...
In an open cloud computing environment, many functional-equivalent services can be provided by different providers with different SLA (service Level agreement) levels, then it is an important problem for service consumers to select the optimal one from lots of service candidates. Considering drawbacks of existing methods, we propose a systematic approach for this multi-objective optimization problem...
