In this paper, a general mathematical model for calculating the sensitivity coefficient and sensitivity of heat exchange networks with arbitrary structure is proposed, and a method to solve the mathematical model is given. The computer program is compiled and evaluated by examples. The sensitivity and sensitivity coefficient of the heat exchanger network are very important for analyzing the influence of disturbance variables on the controlled variables and the objective function. According to the sensitivity coefficient of the heat exchange network, the operation performance of the heat exchange network can be analyzed, and the best improvement scheme for the heat exchange network can be proposed.
