Extended P-graph applications in supply chain and Process Network Synthesis

•The paper reviews the extended application of P-graph in Process Network Synthesis (PNS) problems.•Application of P-graph demonstrates topology of transportation, location and allocation network analysis.•Several future works has been proposed for the P-graph applications in PNS.

The fast development of new products, process technologies and production methods has made the decision making in process design and synthesis a complicated task. Combination of all feasible process pathways and solutions creates a huge super structure. Thus, to determine the optimum solution and flexible alternative solution is a big challenge for Process Network Synthesis (PNS). Process graph (P-graph) approach has been extended gradually to provide a friendly and fast optimum result for PNS problem. This paper overviews the application of P-graph in new PNS areas in the aspect of synthesis, optimisation, planning and management. The paper demonstrates the extension of P-graph via several case studies such as effective supply chain systems, carbon emission reduction systems and cleaner production process synthesis. The paper also highlights the advantages of P-graph in process network synthesis.
