Use of Model-Based System Engineering methodology and tools for disruption analysis of supply chains: A case in semiconductor manufacturing

In the age of complex and large-scale systems, Model-Based System Engineering (MBSE) is increasingly becoming a sine qua non in industry due in large part to a wider use of software applications and an increased move towards standardization. In this study, we research the application of the MBSE methodology (definition, design, analysis, and synthesis) to disruption management with a specific focus on a semiconductor supply chain case study. Within this methodology we use three MBSE tools, namely OWL, BPMN, and SysML, with the main focus being on definition of the problem to ensure that the “correct” problem is solved. The article does not report on any new research into the MBSE tools, but applies the available tools. Many of these tools have limitations, especially in the area of analysis and synthesis, that have been overcome if not widely adopted, in the area of product design (i.e., finite element analysis and simulation, etc.), which is a limitation in the type of systems studied here, i.e., a supply chain system which is a discrete event system. Through the application of the MBSE methodology and the application of the three MBSE tools, a comparison is provided that highlights further opportunities and obstacles, but which ultimately demonstrates a positive proof that the MBSE methodology is necessary for revealing sources of systematic disruptions within a complex integrated industrial information system.
