Process design is an academic concept and methodological approach concerned with the systematic synthesis, configuration, and optimization of sequences of operations or transformations. This field investigates the optimal arrangement, parameters, and control strategies for achieving desired outputs from inputs within a defined system boundary. Key characteristics include the application of scientific principles, modeling, simulation, and optimization techniques to ensure efficiency, reliability, safety, and performance objectives are met, with its significance lying in enabling the creation, analysis, and improvement of complex systems across diverse domains such as chemical engineering, manufacturing, and energy production.
