摘要
针对基于文档(TBSE)方法在设计地铁列车乘客信息系统(PIS)时所面临的设计集成度低、开发效率低、功能之间的联系性差及可追溯性差等问题,将PIS的3个主要功能进行模块化处理,提出智慧乘客信息系统(IPIS),并运用基于模型的系统工程(MBSE)思想对系统进行设计建模.提出了IPIS系统从黑盒到白盒的设计建模方法,涵盖了利益相关方分析、涉众需求分析、用例和用例场景分析、黑盒活动分析、白盒活动分析、功能分析、系统需求分析、系统架构设计8个阶段,并利用系统建模语言(SysML)构建IPIS系统功能元模型,以提高模型重用率.通过一个IPIS系统设计实例验证该方法的有效性和可行性.
Abstract
In response to the challenges faced by the text-based system engineering(TBSE)approach in designing passenger information systems(PIS)for subway trains,including low design integration,low development efficiency,weak inter-function connectivity,and poor traceability,this paper proposed a modular approach for the three primary functions of PIS,introducing the intelligent passenger information system(IPIS).Combining this with model-based systems engineering(MBSE)methods,the system was designed and modeled.The IPIS system's design and modeling method was presented,transitioning from black-box to white-box.This process encompassed eight stages,including stakeholder analysis,stakeholder requirements analysis,use case and use case scenario analysis,black-box activity analysis,white-box activity analysis,functional analysis,system requirements analysis,and system architecture design.system modeling language(SysML)was utilized to construct the IPIS system's functional element model,enhancing model reusability.The effectiveness and feasibility of the proposed approach were validated through a practical IPIS system design example.
