BPMN 이벤트 기호를 활용한 가상플랜트 시스템 기능 통합 설계와 구현

Abstract

CPS (cyber-physical system) or digital-twin systems for companies’ operational systems requires diverse interactions with enterprise-wide information systems. An information system development methodology is necessary to capture and express the interactions among functional modules and relevant data characteristics. The proposed modeling approach adopts the event notations of the BPMN (Business Process Modeling Notations) standard. The event notations are expressed in data models and module architecture design. The proposed modeling approach helps engineers to understand periodic or time related issues in data and system modules. The usage of the proposed approach is described with a sensor-based virtual plant system example. A sensor-based virtual plant system is a digital-twin system for a refinery plant, and analysis/ design examples of the system are shown to show effectiveness of the proposed approach.
