Claim 2:
3. The method of designing a heat exchanger group according to claim 1, wherein, when a plurality of the heat exchanger groups are to be installed in the processing plant, the method further comprises:
a fourth step of executing the first step to the third step for each of the plurality of heat exchanger groups to calculate first Pareto solutions being the Pareto solutions for the objective functions of the installation length and the total heat transfer area; and
a fifth step of selecting a combination of the installation length and the total heat transfer area from the first Pareto solutions for the each of the plurality of heat exchanger groups and calculating at least one of a total installation length of the ACHEs of the plurality of heat exchanger groups when the ACHEs are arranged in one row and device cost of the plurality of heat exchanger groups based on a result of the selection of the combination.
