The problem of improving structural flexibility of heat exchanger networks is to retrofit the configuration of a heat exchanger network whose flexibility does not meet the requirement and enhance its flexibility, so as to decrease its energy consumption caused by uncertain parameters.

According to the structural characteristics of parallel machine lines in Flexible Manufacturing System (FMS),this paper developed the definition and measure of structural flexibility with consideration of different ca- pacity of the machines.

According to the theory of general modular design, general modular product family and platform architecture was presented, concepts of the flexible modular, virtual modular, unit structure and flexible unit structure were discussed, and the idea of modeling the general modular product family on the basis of flexible unit structure was proposed.

Based on indoors simulate experiments and local experiments at 312 national highway in Lanzhou and analyzing with MARC program, the text presents a study on the mechanics properties in upright compress and upright cut and plane pull and plane press of the flexible geocell layer.
