Design and development of complex engineered systems in the aerospace industry have been facing challenges in terms of managing ever-increasing complexity. Due to the disconnect in current multidisciplinary design efforts, the behavior of the system may not be accurately predicted, possibly resulting in a divergence between the project outcome and what the designers envisioned. This is one of the most prevalent challenges observed in the aerospace industry, especially in the integration phase of product development, causing budget and schedule overruns. In this talk, I will focus on the integration of multidisciplinary design into model-based systems engineering practices to reduce the system development times and the allocated budgets. I will present a novel system development paradigm that combines semantic, physics-based and machine learning models to improve the decision-making processes throughout the life cycle of a system. I will cover novel algorithms for transforming systems engineering related knowledge into graph databases and a fusion of graph-based neural network algorithms to leverage the design knowledge for more accurate and explainable decisions. This causal-aware and robust methodology I have developed has shown that the integration of heterogeneous domain-specific knowledge is essential for enabling digital implementation of aircraft systems.
