摘要: 将改善后的公理化设计方法与基于模型的系统设计结合,提出了一种面向复杂工程系统的基于模型的公理化设计方法(Axiomatic model based systems design,A-MBSD)。用例、活动和交互等系统行为作为连接系统功能和结构的桥梁被引入公理化设计中,形成新的行为域,从而整个设计过程能够被需求-功能-行为-结构之间的映射有效地表示。在A-MBSD中,一方面设计师可以利用设计域之间的"Z"字形映射描述系统设计从抽象到具体的演变;另一方面,设计师可以通过独立公理判断系统设计的耦合性,在设计早期发现设计参数之间的冲突。为了保证系统建模的统一性,使用SysML的扩展机制stereotypes将公理设计的核心概念定制到一般的系统设计过程中,形成A-MBSD建模profile。通过一个森林火灾卫星监控系统的设计证明了行为域的引入提高了设计矩阵的可靠性、基于模型的技术保证系统模型的统一性,并使设计师理解功能耦合的原因。

Abstract: The axiomatic design approach is integrated with model-based systems design so that a unified systems design approach axiomatic model based systems design (A-MBSD) for complex engineering systems is proposed. Systems behaviors like use cases, activities and interactions is combined in Axiomatic Design forming a new behavior domain to bridge system functions and structures, which enables the mapping relations among requirements-functions-behaviors-structures represent the whole design process explicitly and effectively. In A-MBSD, designers are not only able to describe the evolvement of a system design process by "Z" mapping among different design domains, but also identify conflicts between design parameters by analyzing the coupling of the system using the Independence Axiom. To maintain the consistency of system models, the A-MBSD modeling profile is constructed through the SysML stereotypes extension mechanism. The result of a Forest Fires Satellite Monitoring and Control System (FFSMCS) design shows that the new behavior domain improves the reliability of the design matrix, model-based technology enhances the unity of the system model and enables designer understand the coupling of a system design.
