中文摘要：
针对云仿真中多种粒度资源共享和按需构建仿真服务的特点及其对仿真资源服务描述框架的新要求,提出了面向云仿真的层次化仿真服务描述框架;对框架中各层次的描述语义进行了定义和形式化描述。将研究成果应用于云仿真系统的仿真服务描述实现中,通过典型实例,验证了所提出的仿真服务层次化描述框架。研究实践表明：面向云仿真的层次化仿真服务描述框架适用于云仿真系统中涉及的各类不同粒度的仿真服务资源,能够从服务属性语义与服务模型语义两个角度对仿真服务进行描述,从而支持基于仿真服务描述的智能化发现与组合调度,实现按需构建仿真服务的云仿真模式。
英文摘要：
According to the characteristics of multi-granularity resources sharing and simulation services establishment as well as its new demand on Simulation Service Description Framework（SSDF）in cloud simulation, a layered SSDF oriented to cloud simulation was proposed. The semantics of each layer in the framework were defined and formalized in OWL-S, and the researches were applied to the description of simulation services in certain cloud simulation system prototype. The proposed layered SSDF was verified by typical example. The result showed that the layered SSDF oriented cloud simulation was suitable for various multi-granularity simulation resources of cloud simulation system, and could described cloud simulation services in both attribute-semantic and model-semantic. Thus the intelligent discovery and automatic combination of simulation services were supported, and the construction of cloud simulation mode was realized.
