Design and modeling method of IPIS system for subway trains
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.
