中文摘要： 多媒体云计算是新兴的热点研究领域之一。本课题研究多媒体云计算中基于服务质量（QoS）和可信性的协同的云资源管理。主要研究内容有：（1）建立分层次、多维度的用户QoS框架，给出用户QoS需求到云资源类型、数量和性能的映射方法；（2）提出一种主观推荐和客观反馈相融合的方法，研究柔性的云资源信任模型和评估方法；（3）基于协同的QoS框架和信任评估结果，提出多任务的云资源调度方法；（4）基于云工作流技术，实现上述方法对多媒体云计算应用的支持。本课题拟建立完善的云资源协同管理体系，特别是填补现有研究在用户QoS需求到云资源的映射方法、基于QoS的云资源信任评估和多任务下的云资源调度方法上的不足。本课题的研究结果对内蒙古自治区草原文化、民族音乐的传承和推广、环境监测与保护等具有重要意义和潜在的应用前景。

英文摘要： Multimedia Cloud Computing is one of the rising hot topics. This project is about cooperative resource management based on quality of services (QoS) and trustworthiness in multimedia cloud computing. Main contents to be researched include: (1) To build a hierarchical QoS framework with multi dimensions firstly, then to give a method of mapping users' QoS requirements to cloud resources' types, quantity and performance. (2) To present a flexible trustworthiness model and a method for evaluating the trustworthiness of cloud resources, considering subject recommendations and object feedbacks. (3) To develop an algorithm for scheduling cloud resources based on the cooperative QoS framework and evaluating results mentioned above. (4) To build a cloud workflow system supporting the above methods and algorithms for multimedia applications. The purpose of this project is to build a complete architecture for cooperative management of cloud resources, whose core contents include mapping users' QoS requirements to cloud resources, evaluating the trustworthiness of cloud resources, and scheduling cloud resources based on QoS and trustworthiness. The expecting results of the project are meaningful for the following potential application areas, such as traditional culture and music of Mongolians, environment inspecting and pr
