Analytical Investigations in Heat Exchanger Network Synthesis
Although exact algorithms have been successful in tackling HENS problems of small size, heuristics are required for large-scale problems, and nothing is known about the quality of the solutions provided by heuristics. Analytical investigations are suggested to characterize the behavior of both …
