摘要
提出了一种支持Web服务动态组合的框架,并在此基础上对Web服务组合中的服务优化选择问题建模,根据用户设置的QoS约束条件,将服务优化选择问题分成3类,并分别给出了相应的服务选择算法。实验证明算法在保证一定优度的同时亦具有良好的时间性能。
A mathematical model of QoS-aware service selection optimization problem is built in service composition.According to users＇ constraints,optimization problems of service selection are divided into three categories.And for each category a selection al- gorithm is proposed.Some simulations are conducted to show the performance of these algorithms.
