Dynamic Optimization
Design for Dynamic Performance

Research Title
Large-scale dynamic optimization for design and operation of chemical processes

Research Objectives
Our research is focused on the development of optimization-based solution techniques for design and operation of large-scale processes that are described using differential-algebraic equations (DAEs). In particular, the integrated design and control (IDC) of chemical processes has long been shown to be an affective approach for establishing agile plant designs. Current solution implementations that utilize dynamic optimization techniques have shown to be highly effective at simultaneously estabilishing economic and performance concious process designs. This has lead to larger plantwide applications of IDC which are highly computationally demanding, particularly when uncertainty is included and a multi-scenario dynamic optimization solution strategy is adopted. To combat the growing intractability of such multi-scenario formulations, our research seeks to investigate and develop solution strategies that incorporate decomposition techniques to break the otherwise large problem into several smaller and managable pieces that can be solved using parallel computing techniques.
