基于模糊描述逻辑的 C4ISR 系统上下文环境分析方法

摘要

为了实现指挥信息系统自适应的决策支持，将上下文感知技术融入指挥信息系统的分析与设计，首先提出了 C4ISR 系统上下文元本体，借此定义指挥信息系统上下文环境的基本语义框架。在此基础上，结合元本体以及面向目标的需求分析方法思想，提出了 C4ISR 系统上下文环境信息获取和建模表示方法。此外，将模糊本体推理技术引入指挥信息系统上下文环境推理分析环节，通过设计上下文环境模型到本体的形式化规约算法，有效地将指挥信息系统的上下文环境信息形式化，并通过本体推理技术，实现了对系统上下文环境的推理分析。%To realize an adaptive decision support and service intelligence C4ISR system,the pervasive com-puting and context-aware technique with the analysis and design of the C4ISR system is integrated.The C4ISR context-aware meta ontology is proposed to construct the semantic framework of the C4ISR context.And then a domain-specific modeling language for C4ISR context-aware knowledge modeling is defined by extending the uni-fied modeling language (UML)class and association with fuzzy constructs in order to model the fuzzy concepts of the context-aware knowledge.Additionally,a C4ISR context-aware knowledge transition algorithm is defined to support an automatic context-aware reasoning and analysis.
