【Abstract】 This paper presents a new model for the large\|scale heat exchanger networks (NP\|hard problem) and also proves its equivalence with the original question. On the one hand, the new model can give the feasible domain of optimal parameters, so it avoids a large number of infeasible solutions. On the other hand, because the number of the optimal parameters of the new model decreases several times than that of the original question, the algorithm given in the paper can obtain the global optimum solution with higher probability.更多还原
