Automated trade study analysis based on dynamic requirements verification in the model‐based system engineering

Abstract

In this complex world, where evolving systems communicate independently to achieve a common goal, the ability for an engineer to develop systems with traceability to requirements, using one integrated architecture model that enables all types of automated analysis (e.g., impact analysis, gap analysis, trade study analysis, and simulation) is becoming more and more vital. Today, the core enabler for automated analysis is the application of model‐based systems engineering practices. Model‐based systems engineering is used to capture system or systems of systems architecture as descriptive and analytical system models, which relate text‐based requirements to the architecture and provide an infrastructure to support trade study analysis. One of the core techniques to perform such analysis is requirements verification. This paper proposes an approach for an automated trade study analysis based on dynamic requirements verification in the model‐based systems engineering environment, with a goal to support trade of analysis both in the system of systems and systems engineering domains.

Towards an Approach to Co‐Execute System Models at the Enterprise Level

“…Kotronis et al (2016) describes how to apply simulation to SysML models that describe a rail transport system. Bankauskaite, Strolia, and Morkevicius (2021) presents the use of simulation in a trade study of an automatic transmission system. Furthermore, many researchers have developed and introduced new methods to analyze systems using simulation in conjunction with the SysML model.…”

Utilization of system models in model-based systems engineering: definition, classes and research directions based on a systematic literature review

“…A common use case is the simulation of SysML models, which is often executed in the SysML tool itself (Figure 4e). Typically, model simulations focus on the verification of the model, for example, verifying requirements and designs (Morkevicius & Jankevicius 2015), checking consistency (Bankauskaite & Morkevicius 2018) or event simulation to check the behaviour of a system (Liu et al 2014). Insights from these simulations are likely used to enhance the system model itself (Figure 4d).…”
