Description
Summary:Process-network synthesis is the determination of the optimal network structure of a process system together with optimal configurations and capacities of the operating units incorporated into the system. The aim of developing more and more sophisticated solver algorithms is to find the optimum as fast as possible and increase the circle of practically solvable process synthesis problems. The P-graph framework can effectively reduce the number of structures to be examined and accelerate the computation searching for the optimum due to the exploitation of combinatorial characteristics of candidate solution structures. A cooperative parallel implementation of P-graph algorithms have been published recently to exploit the capabilities of multi-core and multiprocessor systems (Bartos and Bertok in De Gruyter Ser Logic Appl 1:303-313, 2015 (See CR5)). The parallel implementation has increased performance significantly but this can be further improved by fine tuning the parameters of the parallel algorithm. Outcomes of experiments on parameter optimization are to be presented herein.
