基于本体的仿真服务定制与组合

A Ontology Based Simulation Service Customization and Composition

为实现快速构建仿真系统,提出了面向服务的仿真开发模式,基于本体和Web服务进行仿真服务的定制与组合。给出了本体、仿真服务等基本概念,详细定义领域本体、需求本体和服务本体;提出了仿真服务定制模型及系统框架;分析了需求目标与仿真服务之间存在的逻辑关系,并确定了服务定制的一般过程。基于网格工具集初步实现了仿真服务定制和组合系统,验证了上述方法的可行性。

Aimed at rapidly building simulation systems,service oriented simulation development is put forward,based on ontology and web service mechanism to custom and compose simulation services.First,some basic definitions,simulation services customization model were proposed and its supporting system framework were presented,among which domain ontology,requirement ontology and service ontology were particularly described.Logical relationship between requirement goals and simulation services were analyzed,upon which the general process of service composition were studied.In the end,with the support of Grid Toolkit a prototype system was realized to testify the feasibility of our methods.
