A Method for Calculating the Association Degrees between Concepts of Concept Networks

Depicting the associating degrees between two concepts and their relationships are major works for constructing a multi-relationship fuzzy concept network. This paper indicates some drawbacks of the existing methods of calculating associating degrees between concepts, and proposes a new method for overcoming these drawbacks. We also use some examples to compare the proposed method with the existing methods for calculating the associating degrees between two concepts in a multi-relationship fuzzy concept networks.

基于MBSE的装备作战概念模型化设计

[目的]为了在装备研制过程中发挥“作战概念”的作用,需形成规范化的作战概念文档(OCD),并解决其模型化设计方法的问题,从而在装备研制中实现系统工程过程从文档中心向模型中心的转变。[方法]针对装备使用作战概念,即ConOps或OpsCon,首先,借鉴美军相关理论和IEEE 29148:2018,ANSI/AIAA G-043B-2018等标准,提出作战概念文档目录的建议;然后,研究基于SysML的作战概念建模技术、基于UML Profiles的作战概念框架设计技术和基于MSDL/C-BML的作战想定开发技术。[结果]该研究工作有效实现了作战概念文档的规范化和模型化设计。[结论]在装备需求论证过程中,通过为系统各方提供一个无二义性的作战概念模型和工程环境,将有助于提高装备需求论证的效率。
