摘要/Abstract

摘要：

定性建模技术相比定量建模技术能更加准确地描述复杂系统中的混沌性、不确定性和不可预测性。为全面系统地描述定性定量复杂系统,将定性建模技术跟定量建模技术相结合,提出一种基于多学科虚拟样机建模仿真理论(COSIM)的集成建模方法。在此基础上引入基于置信规则的定性知识和定性接口的描述,提出了集成建模的层次化模型结构的形式化表示方法;同时,基于对仿真系统中定性推理和定量解算的统一调度,给出了一种定性定量协同求解方法,最后,通过对UMl建模语言的扩展,提出了集成建模语言。通过设计并实现鱼雷规避仿真系统,验证了该建模方法的有效性。

关键词: COSIM, 定性定量结合, 置信规则, 建模语言

Abstract:

Compared to quantitative modeling technology,qualitative modeling methods can describe the chaos,uncertainty,and unpredictability of complicated systems better.To describe qualitative and quantitative complex systems systematically,qualitative modeling and quantitative modeling are combined.In this paper,a qualitative and quantitative integrated modeling based on theory of modeling and simulation for Multidiscipline Virtual Prototype (COSIM) is proposed.A description of qualitative knowledge and qualitative interface based on belief rules is given,and the formal description of hierarchical model structures of the integrated modeling is stated;a quantitative/qualitative collaborative solution is proposed based on unified dispatch of qualitative reasoning and quantitative calculation in simulation system.Finally,integrated modeling languages are given based on the expansion of the UML modeling language.The validity of the modeling method is verified by designing and realizing the simulation system of torpedo evasion.

Key words: COSIM;combining qualitative and quantitative;belief rules;modeling language
