Process Optimization for Multiple Objectives: Principles, Applications and Programs


Background: Optimization of processes for single objective is well established with numerous applications in both academia and industrial practice, and several programs are readily available for process optimization. On the other hand, optimization applications often have more than one objective, which requires multi-objective optimization (MOO). Over the last two decades, there has been significant progress in MOO and its applications. Currently, process optimization studies in academia are often for two or more objectives. After the formulation of process optimization problem, MOO consists of two main steps: (a) generation of Pareto-optimal (non-dominated) solutions using a suitable numerical technique, and (b) selection of one of the Pareto-optimal solutions (referred to as multi-criteria decision analysis/making).


Objective and Outline: The aim of this short course is to present MOO principles, chemical engineering applications and programs for optimizing processes for multiple objectives. It will cover the following: (a) MOO, its results and benefits, (b) principles of selected techniques for solving MOO problems, (c) review of chemical engineering applications, (d) outline of a few selected applications, (e) readily available programs for MOO, and (f) use of MS Excel based programs for solving MOO problems. Two Excel programs for MOO will be provided to all participants for their use after the short course.          


Learning Outcomes: After attending this short course, participants should be able to:

  • Describe MOO, its results and its benefits
  • Outline principles of common techniques for solving MOO problems
  • Discuss selection of one of the Pareto-optimal solutions
  • Use MS Excel programs for solving MOO problems
