中文摘要： 随着越来越多云服务的成功应用，云市场下终端用户、SaaS服务商、PaaS服务商和IaaS服务商所构成的云服务系统中各方间的经济利益问题受到众多学者的广泛关注与深入研究。然而从云服务系统整体收益角度出发讨论云市场下各参与者间的利益博弈问题使得所有参与者能够获得共赢的最优策略却鲜有研究。本项目的主要研究内容为：(1)基于层次优化的结构特点，分析云服务系统中各参与者之间的嵌套递阶博弈关系，建立终端用户参与决策的云服务定价策略模型，云代理(Broker)合约机制和现货市场下云服务资源有效分配模型及最优云服务组合框架，使得各个云服务商和终端用户获得最佳收益。(2) 重点研究求解层次优化模型的直觉模糊交互式算法，得到使得各层决策者获得共赢的最优策略，并构造层次优化问题有效的数值优化算法和智能算法。(3)进行数值模拟计算，验证模型的正确性和算法的有效性。本项目的研究具有重要的理论意义和应用价值。

英文摘要： With the growing number of successful applications of Cloud Computing Services, many researchers have devoted themselves into the economic benefit problems between the end-users, SaaS providers, PaaS providers and IaaS providers in the cloud service system. However, little attentions are paid on researching the benefit game among the participants in the cloud market to make all of them to obtain the win-win strategy from the perspective of the overall revenue of the cloud services system. The main contents of the project are as follows: (1) Based on the structural characteristics of the hierarchical optimization, we analyze the nested hierarchical game relationship among the participants in the cloud service system. Then we establish the following three models: the cloud service pricing model with end-users' participating the decision-making process, the efficient allocation model of cloud services under the contract mechanism and spot market and the model framework of the optimal strategy of the cloud services composition. Through these models, we want to research how to make each cloud providers and end-users to obtain the best benefit.(2) The intuitionistic fuzzy interactive algorithm will be proposed for solving the hierarchical optimization problems to obtain the optimal win-win strategy. In addition, we will propose the effective numerical optimization algorithms and intelligent algorithms to solve the other hierarchical optimization problems. (3) The certain numerical experiments will be implemented to verify the correctness of the model and the effectiveness of the algorithm. This research has important theoretical significance and application value.
