摘　　要：SSE-CMM可用于过程改进、能力评估和提高用户的信任度,是组织和实施安全工程的通用方法,是系统安全工程领域成熟的方法体系。SSE-CMM结合了计算机科学中的CMM模型、管理学中的全面质量管理思想和统计理论,将系统安全工程转换为一个具有良好定义的、成熟的、可测量的先进工程学科。SSE-CMM评估面临领域知识缺乏、数据量大、证据类型多样、过程繁琐、证据与问题匹配复杂等问题。为有效提高评估效率,本文依据本体论、证据理论、语义网、智能信息检索、智能自动匹配等技术和方法,针对乏燃料后处理系统,设计了一种基于领域本体的智能评估软件系统,主要包括领域本体建模和管理、证据自动收集、问题和证据自动匹配、过程评估等4个子系统,技术体系结构分为数据层、本体层、知识层、服务层、表示层5层。We can improve the processing, the evaluation of capability and promote the user＇s trust by using system security engineering capability maturity model （SSE-CMM） . SSE-CMM is the common method for organizing and implementing safety engineering, and it is a mature method for system safety en- gineering. Combining capability maturity model （CMM） with total quality management and statistic theo- ry, SSE-CMM turns systems security engineering into a well-defined, mature, measurable, advanced engi- neering discipline. Lack of domain knowledge, the size of data, the diversity of evidences, the cumber- someness of processes, and the complexity of matching evidences with problems are the main issues that SSE-CMM assessment has to face. To improve effectively the efficiency of assessment of spent fuel repro- cessing system security engineering capability maturity model （SFR-SSE-CMM）, in this paper we de- signed an intelligent assessment software based on domain ontology and that uses methods such as ontology, evidence theory, semantic web, intelligent information retrieval and intelligent auto-matching techniques. This software includes four subsystems, which are domain ontology creation and management system, evi- dence auto collection system, and a problem and evidence matching system. The architecture of the soft- ware is divided into five layers： a data layer, an presentation layer. ontology layer, a knowledge layer, a service layer and a presentation layer.
