Field of systems engineering (SE) is developing rapidly and becoming more complex, where multiple issues arise such as overcomplexity, lack of communication or understanding of the design process on different stages of its lifecycle. Model-based systems engineering (MBSE) has been introduced to overcome the communication issues and reduce systems complexity. A novel approach for modelling interactions is proposed to enhance the existing MBSE methodologies and further address the identified challenges. The approach is based on graph theory, where pre-defined rules and relationships are substituted and reorganised dynamically with graphical constructs.

A framework for reducing complexity and improving logic modelling in MBSE with metagraph object-oriented approach is presented. This framework is tested in use cases from literature, where the model-based systems approach is applied to design an automobile system to match the acceleration requirements, and to improve a CubeSat nanosatellite communication subsystem. Through the use case scenarios, it has been proven that the methodology framework meets all the identified functional and design requirements and achieves the aim of the research.

This work may be viewed as a step forward towards more consistent and automatic modelling of interactions among subsystems and components in MBSE. Automation techniques have multiple applications in systems engineering field as engineers always aim to produce higher quality and cost-effective products in less time and that is achieved by integrating knowledge on every stage of a development lifecycle. In addition to those advantages for SE field, the research provides basis for potential research proposals for future work in various engineering fields such as knowledge based engineering or virtual engineering.
