Dear Sir/Madam, Could you please disseminate following message to CAST10 community. Best regards Dr. Shivom Sharma EFPL, Switzerland Greetings from Prof. Dr. Gade Pandu Rangaiah and Prof. Dr. Andrew Hoadley, Guest Editors of the open access journal *Processes *(ISSN 2227-9717; indexed in *SCIE*-Web of Science and *Scopus*-Elsevier; IF: 1.279; http://www.mdpi.com/journal/processes). We invite you to submit your manuscript to the Special Issue of *Processes* on Multi-Objective Optimization of Processes ( https://www.mdpi.com/journal/processes/special_issues/multi_objective). Deadline for manuscript submissions: **15 September 2019** **Special Issue Description* * Optimization has been playing a significant role for designing and controlling improved processes for many decades. However, over recent years, the view of an optimized process has changed from considering just the economic return to include other objectives including environmental impacts, social impacts, process safety, on-stream time, reliability, maintainability, and recyclability, to name just some of the possibilities. When a process designer needs to consider more than one criterion, this is known as multi-criteria decision analysis/making (MCDA/M). Multi-objective optimization (MOO) or optimization for multiple objectives has been a fast developing field of research, because of its ability to identify conflicts between objectives using Pareto-generating techniques that can provide many Pareto-optimal solutions at the same time. This Special Issue on “Multi-Objective Optimization of Processes” focuses on new developments and applications of MOO to processes and systems of interest to chemical engineers. Topics include but not limited to the following: - New techniques for multi-objective optimization; - Developments in the selection of Pareto-optimal solutions; - Applications to design and control of new processes and systems; - Applications to retrofitting/revamping of existing processes and systems; - Applications in product design, energy systems, food processing, mineral processing, and drug delivery; - Optimization for diverse objectives related to economics, environmental impact, safety, controllability, and/or flexibility. **How to Submit** Main types of contributions published in *Processes* are Articles, Communications, Reviews, Conference Papers, Perspectives, Viewpoints. 1.
