text: At Pannon University software the tools PNS Editor and PNS Studio were programmed to generate maximum structure of processes. This software includes the p-graph method and MSG, SSG and ABB branch and bound algorithms to detect optimum structures within the maximum available process flows.
  PNS is used in different applications where it can be used to find optimum process structures like:
  * Process engineering: Chemical process designs and the Synthesis of chemical processes is applied in different case studies.
  * Optimum energy technology networks for regional and urban energy systems: In case of regional and urban energy planning the financially most feasible solution for resource systems is selected as target value. With this setting material- and energy flows, energy demand and cost of technologies are considered and the optimum technology network can be found. Simultaneously the robustness of technologies due to price changes and limitations in resource availability can be identified.
  * Evacuation routes in buildings: The aim is to find optimal routes to evacuate buildings depending on specific side parameters.
  * Transportation routes: In this research area transportation routes with minimum cost and lowest environmental impact can be identified.
