Structural modelling in systems engineering

• Pornpan Songprasop

System engineering has been widely used to develop complex hybrid systems combining discrete and continuous aspects. A particular language to capture the system requirements is SysML. We define a conceptual model of the systems engineering which formalizes SysML structure concepts by means of the higher-order entity relationship model and further provide a glimpse of formalized behavioural concepts with a hybrid extension of Abstract State Machines. We also present an exemplification of SysML structure diagrams on a hemodialysis machine case study by exploiting the Enterprise Architect tool.
