  • 1. Design Visualisation Conclusions An interactive exploration environment for complex process design Eric S Fraga Centre for Process Systems Engineering Department of Chemical Engineering UCL 25 May 2010 An interactive exploration environment for complex process design 1 / 14
  • 2. Design Visualisation Conclusions The problem of design Process design should be informed by robust optimisation with condence in results to aid in insight generation. Diculties Cost versus Pressure complex non-linear, non-convex, discontinuous & noisy models, 1500 1400 1300 combinatorial search space, 1200 Cost (k$/yr) 1100 1000 900 800 small, possibly non-convex, feasible 700 600 regions, 0 5 10 15 20 25 30 35 Pressure (atm) ill- or un-dened objective function and constraint equations outside feasible regions, and An interactive exploration environment for complex process design 2 / 14
  • 3. Design Visualisation Conclusions Visualisation and interaction Computer based tools for design and optimization are intended for use by non-experts. Visual representations critical for ease of use. Interaction can enable engineer to apply own intuition. Strategy is to combine data analytics, visualisation, and robust (hybrid) optimisation. Applications in energy, water, carbon capture, sustainability, and control. An interactive exploration environment for complex process design 3 / 14
  • 4. Design Visualisation Conclusions Example: Heat integrated design Task Identify potential integrations for given conguration. Enable process modication for better integration. Help engineer identify design alternatives. An interactive exploration environment for complex process design 4 / 14
  • 5. Design Visualisation Conclusions Motivation Complex interactions which are dicult to visualise: 1 Normalised values 0 R1 R2 P1 P2 P3 R3 R4 P4 $ Qh Qc Design variables and objectives Motivates need for design specic visualisation methods.

  • 6. Design Visualisation Conclusions Requirements The visualisation and interaction tool must address the following issues represents the underlying designs indicates relative performance for one or more criteria is scalable for large design spaces An interactive exploration environment for complex process design 6 / 14
  • 7. Design Visualisation Conclusions Solution: 2-d representation Features: units represented, designs connected, scalable An interactive exploration environment for complex process design 7 / 14
  • 8. Design Visualisation Conclusions Connectivity Procedure discrete sampling of space generated by rst stage search procedure. connectivity represented by an acyclic graph edges connect neighbours based on similarity. neighbourhood identication algorithm is greedy so could be improved.

  • 9. Design Visualisation Conclusions Scalability Properties current design centred. specic unit highlighted. other designs are smaller the further away they are. vertical position depends on Example with 1000 direction of design changes. design points.
