Optimization strategies are essential at all levels of decision-making in chemical and energy processes, including process development, process synthesis and design, and finally process operations, control, scheduling and planning. Challenges include the formulation of well-posed and well-conditioned models, development and application of efficient, reliable optimization algorithms, and post-optimality analysis to interpret solutions and assess robustness to model and external uncertainties.

This talk describes a synthesis of optimization concepts and algorithms that enable

* large-scale nonlinear programming

* nonintrusive decomposition strategies

* inclusion of reduced order models,

in order to address challenging nonconvex, multi-scale process problems. These elements will be demonstrated through systematic strategies for the optimal design of energy management systems, demand-side optimization for specialty chemicals and integrated optimization for polymer process operations.


Lorenz T. (Larry) Biegler is Covestro University Professor of Chemical Engineering at Carnegie Mellon University. His research interests lie in computer aided process engineering (CAPE) and include process flowsheet optimization, optimization of systems of differential and algebraic equations, reactor network synthesis and algorithms for constrained, nonlinear process control. Contributions in these areas include analysis and development of nonlinear programming algorithms, optimization software design and application to real-world chemical processes and energy systems. He is an author on over 550 archival publications and 2 textbooks, a Fellow of AIChE, IFAC and SIAM, and a member of the US National Academy of Engineering.

This lecture series is endowed in the name of the late Spencer C. Schantz, who graduated from Lehigh in 1955 with a B.S. in Industrial Engineering. Following progressive responsibilities with several electrical manufacturing companies, in 1969 he founded U.S. Controls Corporation and became its first CEO and President. The Spencer C. Schantz Distinguished Lecture Series was established by his wife Jerelyn as a valuable educational experience for faculty, students and friends of Lehigh’s Industrial and Systems Engineering department.
