Welcome to SiDi Lab

The System Integration & Design Informatics Laboratory (SiDi Lab) is a research lab in the Walker Department of Mechanical Engineering at the University of Texas at Austin. The research of SiDi Lab is focused on system science and design science as well as the intersection between these two areas. The lab aims at building the decision-centric science foundations for complex systems engineering and design. Such foundations will facilitate the integration within complex systems and amplify the data-driven power in engineering design and design research. Particularly, our research projects encompass the following areas:

  • Complex systems engineering and design, such as predicting system structural evolution using complex networks, estimating local decision-making behaviors in complex socio-technical systems.
  • Decision-making in design, such as modeling and analysis of strategic decision-making behaviors in design competition and/or collaboration using game theory and behavioral experimentation.
  • Artificial intelligence in engineering design (e.g., generative design) and its application in human-computer collaborative design and human-machine symbiosis.
  • Decision-based enterprise-driven design, such as customer preferences modeling, game-theoretic analysis, and spatiotemporal analysis on customer behaviors in product design and development.
  • Swarm manufacturing systems, particularly the cooperative 3D printing (C3DP) using fused deposition modeling (FDM).
  • Social design and manufacturing, such as open-source product development, crowdsourcing, and community-based manufacturing.
