(183h) Mathematical Programming Formulations for Design and Manufacturing of Process Families: Applications to Green Energy Systems
AIChE Annual Meeting
Monday, November 14, 2022 - 5:15pm to 5:30pm
In contrast, in this presentation, we focus on the simultaneous, integrated design of process families for low-cost manufacturing and rapid deployment of green energy systems. Similar to product family design approaches, we consider the trade-off between cost-effectiveness, similarities among processes, and satisfaction of requirements and demands of the process. We present multiple mathematical programming formulations for the simultaneous optimization of process families. A mixedinteger linear programming formulation (MILP) utilizes a discretized set of operating conditions and potential sizing options. The MILP formulation is scalable to large problems because of favorable theoretical properties that allow us to significantly reduce the number of binary variables in the formulation. However, the time-consuming bottleneck of this approach is computation of the input data
obtained by sampling across the potential design space. In contrast, we also propose a mixed-integer nonlinear approach that directly works with the process model to determine optimal sizes across operating conditions while avoiding the need to precompute large numbers of simulations. We provide computational comparisons between these formulations, along with a discussion of the theoretical properties of these formulations. We also present case studies that demonstrate the value of this approach in addressing the challenges of rapid, broad deployment of related process systems.
