On the reformulation of some classes of PNS-problems as set covering problems

Tartalmi kivonat: | Process network synthesis (PNS) has enormous practical impact; however, its solution is difficult in general. This experience has been recently reasoned by Blázsik and Imreh who pointed out that PNS-problems axe NP-hard. The y proved that a simple subclass of PNS-problems is equivalent to the class of set covering problems. In the present paper, it is shown that more general classes of PNS-problems can also be reformulated as set covering problems. This enables the sophisticated techniques developed for solving set covering problems also to be applied for solving some PNS-problems. |
