给出语义网格环境下多语言信息资源调度的体系结构,构建语义网格环境下多语言信息资源调度的有色时延Petri网模型。利用该模型的可达调度图,给出用户对所有语言种类请求的满足率与调度系统的完成率的计算公式,分析用户请求及调度系统的可行性与有效性。通过算例和模拟,得出所模拟系统的有效调度流程,以及有效调度的周转时间。结果表明,该模型不仅可以直观地描述多语言信息资源调度流程,还可以用数学方法来分析其特性,因此是可行和有效的。
The architecture of multi-language information resource scheduling in semantic grid environment is given, and a colored and time-delay Petri net model of multi-language information resource scheduling in semantic grid environment is constructed. Using the reachable schedule diagram of the model, the formula for calculating the user satisfaction rate of all kinds of language requests and the completion rate of the scheduling system is given, and the feasibility and effectiveness of the user request and scheduling system are analyzed. Through the example and the simulation, the effective scheduling process of the simulated system and the turnaround time of the effective scheduling are obtained. The results show that this model not only can intuitively describe the process of multi-language information resource scheduling, but also can be used mathematical methods to analyze its characteristics, so it is feasible and effective.
