摘　　要：提出一种基于激励机制的负载均衡和服务质量感知服务组合(LBQSC)方法.首先,构建一个全局约束分解模型,并采用文化遗传算法求解;其次,考虑服务质量(QoS)和负载构造激励合同,提出一种基于激励机制的服务选择算法,通过不断激励QoS的动态调整获取最优服务;最后,在QWS 2.0综合数据集上进行对比实验.实验结果表明:基于激励机制的负载均衡和QoS感知服务组合方法能在保证负载均衡的情况下有效地获取高质量的组合服务.An incentive mechanism based load balance and aware service with service quality composition(LBQSC)method is proposed.Firstly,a global constraint decomposition model is constructed and solved by cultural genetic algorithm.Secondly,considering the quality of service(QoS)and load structure incentive contract,a service selection algorithm based on incentive mechanism is proposed to obtain the optimal service through constantly dynamic adjustment of incentive QoS.Finally,a set of comparative experiments on the QWS 2.0 dataset are carried out.The experimental results show that the LBQSC method can effectively obtain high-quality composite services under the condition of ensuring load balance.
