基于模糊UML的装备保障知识建模方法

Equipment Support Knowledge Modeling Based on Fuzzy UML

装备保障业务需求建模是装备保障信息系统研发的重要环节,准确描述业务概念和关系是获取高质量需求分析产品的重要前提。然而,该业务领域中用户目标、业务效果等核心要素常包含模糊或不确定信息,容易引发系统研发各方的需求理解偏差,从而给系统后期的设计、开发带来巨大隐患。针对上述问题,首先从装备保障领域知识建模出发,挖掘本领域核心知识,构成装备保障领域知识本体,在此基础上借助UML建模语言MOF层扩展机制,引入模糊评估属性和建模元素,进而形成一种可用于该领域信息系统业务建模分析的领域特定建模语言。该建模语言对领域内存在的明确和模糊需求信息同样具有良好的表达能力,便于系统研发各方在信息系统需求分析阶段达成共识,进而为准确捕捉装备保障业务需求提供技术支持。

Equipment support business requirements modeling is the key issue of equipment support information system development.Accurate description of the business concepts and relations is a prerequisite of high-quality requirements analysis products.However,the core elements such as user objectives and business effects in the business field often contain uncertain or vague information,which is easy to cause the misunderstanding between stakeholders of the to-be system and the failure of the project,thus bringing huge hidden dangers to the design and development of the system in the later stage.To solve these issues,firstly starting from the knowledge modeling of equipment support domain,the core knowledge of this domain is mined to form the knowledge ontology of equipment support domain.And then a domain-specific modeling language for equipment support system modeling is defined by extending the MOF mechanism of UML with the equipment support domain ontology and the fuzzy evaluation attributes.It can model both the certain and uncertain requirements information,and promote a common view between stakeholders of the to-be system.
