Abstract

Contemporary Systems Engineering problems are becoming increasingly complex as they are being handled by geographically distributed design teams, constrained by the objectives of multiple stakeholders, and inundated by large quantities of design information. According to the principles of model-based systems engineering (MBSE), engineers can effectively manage increasing complexity by replacing document-centric design methods with computerized, model-based approaches. The Object Management Group (OMG) has developed a Systems Modeling Language (SysML) which is a dialect of UML 2.0. This visual modeling language provides a comprehensive set of diagrams and constructs for modeling many common aspects of systems engineering problems (e.g. system requirements, structures, functions, and behaviors). To model the behavior of complex dynamic systems in terms of co-simulation, we need to integrate SysML with advanced engineering and analysis tools. The parametric approach in SysML captures the constraints of the block in terms of mathematical expressions. Though SysML is not intended to solve these expressions independently, they can be solved by a wide variety of solvers integrated with SysML. The core of this work is the establishment of modeling, co-simulation and analysis capabilities that do not exist in SysML independently. In this thesis, case study of Modeling of Hospital Emergency room (Door to Room Section) co-simulated with MATLAB as a solver is used for demonstration. The case study shows patient arrival, quick registration and room allocation using behavioral models in SysML. The behavioral models replicate the door to room process by co-simulating with MATLAB. The proposed work shows the potential application and capabilities of SysML using 1D co-simulation in healthcare.
