Abstract: To solve the problem of manufacturing cloud service composition and avoid the optimization results influenced by initial parameters of intelligent algorithms,an approach for manufacturing cloud service composition was proposed based on teaching-learning based optimization.The process of service composition which was based on Quality of Service (QoS) was analyzed.The QoS evaluation model for a single service was proposed,and the overall QoS evaluation method for composite services was analyzed.The mathematical model for manufacturing cloud service composition and optimization problems was established.The teaching-learning based optimization was utilized to solve the optimal problem.Compared with the improved genetic algorithm and the improved particle swarm optimization algorithm,the simulation results showed that the proposed algorithm could solve the cloud service composition problem effectively.

Key words: cloud manufacturing, service composition, teaching-learning-based optimization, quality of service
