Wire Arc Additive Manufacturing: welding torch mounted on ABB robot

Our research group is composed of skilled professionals and researchers with profound knowledge in manufacturing technologies and engineering design. The group is combining modelling, simulation and experimental efforts in the field of manufacturing systems. The specificity of the group is a unique focus on metamodeling approaches for engineering simulations and decision support. The context is specifically the development of robust metamodeling approaches in scarce data context.

Research focus and goals

The group research focus is the following:

  • Modeling and simulation of manufacturing systems,
  • Early integration of manufacturing considerations in the system development process.
  • Efficient dynamic control and development of additive manufacturing methods based on Directed Energy Deposition, 
  • Knowledge encoding in the form of causal graphs, 
  • Integration of existing knowledge and design of artificial neural networks topologies using causal graphs, 
  • Dimensional analysis theory and its combination with causal graphs, 
  • Causal graph networks for decision-making support, 
  • Multi-Disciplinary Optimization and creativity support for Engineering,
  • The early design process, automatic extraction, and analysis of requirements, 
  • Metrics for system design and manufacturing, 
  • Machine learning with Bayesian Networks using Causal graphs as a precursor.

The team is aiming for three complementary targets. The main outcome of the research is a multi-purpose colored causal graph approach supporting the following goals.

The first goal is to create, for engineering design and manufacturing disciplines, a new form of integrative metamodeling approaches supporting the integration of multiple models coming from various disciplines and developed via heterogeneous modeling and simulation approaches. 

The second goal is to provide a system analysis method for ill-defined problems requiring solely qualitative information.

The third goal is to use the causal graphs as topology design support and precursors for different machine learning methods. They serve as well as pre-training method. 


The research, developed in our group, the intention is to transform the early design, manufacturing and optimization disciplines by providing an automation layer for efficient decision support, modelling, simulation and control in a scarce data environment. 

The result can be new forms of modeling, simulation and control tools for engineering disciplines.
