摘要: Quality of Service (QoS) in orchestrated web services compositions have been well studied with probabilistic and multi-dimensional models. Choreographies that involve message passing among services, on the other hand, require further analysis. In this paper, we begin set QoS domains may be case choreographies algebraic rules for their composition. As manage composition a distributed fashion, techniques to enrich functional specifications are examined using model proposed CHOReOS project. These analyzed reconfigure due or requirements. Studies effects such reconfiguration multiple can lead better understanding optimal runtime configurations along associated tradeoffs. A goal programming approach is also choose Pareto solutions respect diverse domains.
