Research and application of superstructure can effectively solve the problem of energy efficiency in the fields of chemical industry

water treatment

steel

metallurgy and so on

and were commonly found in heat exchanger network

mass exchanger networks

water networks and other networks. This article reviews the heat exchanger network based on the state-space superstructure model

stage-wise superstructure model and mass exchanger network

water network based on two classical ideological superstructure model. After the construction of the superstructure

according to the actual situation of industrial production

the total annual cost is chosen as the general objective function

appropriate algorithm is selected to optimize network superstructure

finally the required new or renovation program are obtained. This paper also summarizes common optimization algorithm

it divided into two categories:deterministic algorithm and random algorithm. Finally

the article describes the problems of superstructure modeling in scientific research and practical application

and its future research directions.
