Candidate Seminar Announcement - Selen Cremaschi

Purdue University School of Chemical Engineering FACULTY CANDIDATE SEMINAR Dr. Selen Cremaschi The University of Tulsa "On Tactical and Strategic Decision Making Under Uncertainty" Tuesday, February 19, 2013 9:00-10:15 a.m. FRNY 3059 Abstract: Most tactical and strategic decisions in process industries, such as research & development (R&D), capital, and infrastructure investments, are made in highly uncertain environments. The explosion of the alternatives with increasing uncertainty prohibits the generation of a comprehensive search space for such problems, and limits the applicability of existing tools and methods developed by the process systems engineering research community. This talk will give an overview of our research activities on developing novel methods to optimize the operation and design of a wide range of applications under uncertainty: (1) surrogate model generation and derivative-free optimization for process synthesis and design of multi-scale processes, (2) systematic procedures for uncertainty propagation and reduction for robust design of chemical processes, (3) efficient solution algorithms for optimization under endogenous uncertainty for strategic decision making. Superstructure optimization is, in theory, a very powerful approach to address tactical problems such as process synthesis for energy applications. However, the resulting mathematical program is difficult, and in some cases impossible, to solve. Surrogate models, simpler functional representations of the underlying complex system, can be used to simplify the problem. We developed three sequential design algorithms to construct accurate surrogate models to be used in optimization problems. These algorithms scale well to problems in high dimensions, and investigate the trade-off between space-filling and adaptive nature of sampling methods. Our results reveal that an adaptive sampling approach is required in order to accurately model strong nonlinearities. Whether we are able to use the fundamental models or surrogate models to define our systems, there are many sources of uncertainty in these models, e.g., model inputs, assumptions, and equations. This uncertainty leads to uncertainties in the outputs of these models such as plant throughput, and environmental impacts. Our group successfully demonstrated that the unique combination of a novel data clustering approach to identify the relevant experimental data with model fine-tuning and evaluation techniques reduces the prediction uncertainty from up to five orders of magnitude to the same order of magnitude. Although this approach is powerful for systems with uncertainties that are independent of decisions, optimization problems with decision-dependent, i.e., endogenous, uncertainty are commonly observed in process industry, e.g., synthesis of process networks with uncertain process yields, and biomass-to-commodity chemicals investment planning. Despite this, mostly due their challenging nature, the research community strayed away from these problems. Our preliminary analysis using simulation-based optimization (SIMOPT) approach revealed the importance of endogenous uncertainties on the overall cost and the resulting decision tree for these problems along with the significant computational cost of SIMOPT. As a new direction to solve these problems, we have recently developed a novel heuristic approach that decomposes the original multi-period multi-stage stochastic program into a series of two-stage stochastic programs, which are then solved rolling through the stages and periods. This approach is highly-parallelizable, and our preliminary results suggest that the solutions obtained are very close to the true solution.

Candidate Seminar Announcement - Chris Wilmer
by Ewing, Virginia G 13 Feb '13

Purdue University School of Chemical Engineering FACULTY CANDIDATE SEMINAR Christopher E. Wilmer Northwestern University, Evanston, IL "Algorithmic Exploration of 'Building-Block' Chemistry: Rapid Discovery of Optimal Gas Storage and Separations Materials" Thursday, February 14, 2013 9:00-10:15 a.m. FRNY 3059 Abstract: In the last decade a wealth of novel materials has been synthesized through what has come to be called "modular" or "building-block" chemistry. This new approach leverages the self-assembly of rigid molecular building blocks that only connect in very specific orientations and stoichiometries. The resulting assemblies are constrained into discrete geometries (e.g., polyhedra, tubes, spheres) or crystalline structures (e.g., metal-organic frameworks (MOFs)). A remarkable feature of building-block chemistry is that the products are typically monodisperse, and their geometry can be predicted a priori. Due to this predictability and the abundance of known building blocks (drawn from the vast organic chemistry literature), the field of MOFs alone, which are promising materials for storing and separating gases, has reported thousands of novel structures in the past few years. While these numerous reports showcase the success of the building-block approach, they also belie the underlying combinatorial difficulty of finding the best material for a given application. Clearly, trying to find the best MOF by experimental trial and error, out of the millions of possibilities, is impractical and inefficient at best. In this seminar, I will present recently developed algorithms that systematically generate all of the hypothetical MOFs that could be made from a library of building blocks. We generated over 150,000 novel MOF structures and simulated their gas adsorption via molecular simulations on supercomputers. In addition to rapidly discovering promising MOFs, we found previously unidentified structure-property relationships that could only have been recognized by taking a global view of MOF structures. Working with synthetic chemists, we synthesized some MOFs identified in silico and found that their measured gas adsorption agreed well with the simulations. Our database of MOFs is publicly available online (hmofs.northwestern.edu) and the following Youtube video (http://youtu.be/QaKSekjAnqY) provides a short (and entertaining!) summary of the research I will discuss. Bio: Chris Wilmer is a graduate student in Prof. Randall Q. Snurr's research group at Northwestern University. He was born in Canada to Polish parents who immigrated to Canada shortly before Poland went under martial law in 1981. Spurred by nanotechnology-driven visions of the future penned by writers Erik Drexler and Ray Kurzweil, Chris acquired a B.A.Sc. degree from the University of Toronto's Engineering Science - Nanoengineering program. Coming to the United States to pursue a Ph.D. in chemical engineering, he took an interest in the American way of developing new technologies - through entrepreneurship. He has co-founded a spin-out company, NuMat Technologies, based on his doctoral research. NuMat has won over $1.2 million in prizes, has been featured in Fortune magazine, and was recently invited to the White House to present its business plan. In addition, Chris has personally won multiple innovation awards, which led to being recognized as a "top solver" by InnoCentive, and more recently, being named to the Forbes Top 30-Under-30 list in Energy Innovation. His research on the computational design of porous materials has been featured on the covers of the journals Energy & Environmental Science, Chemical Science, and Nature Chemistry, and he is the latest recipient of the AIChE COMSEF award for outstanding graduate research in computational molecular science and engineering.
