A hyperstructure model based on temperature fluctuation and networkless shunting heat exchange network and a flexible design method of synchronization optimization are proposed. The pretreatment of the logistics with initial temperature fluctuating within a certain range, namely, the segmentation process, and the principle of segmentation are proposed. The rule-based network superstructure model is proposed and the mathematical model of elastic heat exchange network synchronization optimization is established. The algorithm was used to solve the proposed optimization mathematical model. The principle of subdivision logistics combining and energy relaxation was proposed. The subdivision logistics was merged, and the optimal elastic heat exchange network structure was obtained by energy relaxation method. Through the flexible design of several heat exchange networks, the effectiveness and application prospect of this method are illustrated.
