In the framework of the conflict-based approach, process synthesis is defined as the process of decision making for identifying and handling the design conflicts in order to satisfy multiobjective requirements (Li, 2004). Under this concept, a design problem is decomposed into subproblems instead of applying a hierarchical design. This allows for overcoming the drawback related to the interactions among several hierarchical levels of analysis. The design problem is represented by the conflicts among the interrelated design objectives or by the features of the techno­logical scheme (Li and Kraslawski, 2004). Undoubtedly, this approach represents a change of paradigm in process design, although some aspects should be developed, such as the quantification of the conflicts and heuristic rules in function of their contribution to the conflicts as well as the development of the solving algorithms.
