Coordination Degree Of Composite Systems And Its Application, Ke Qi, Jiaojun Zhu, Dexiong Teng, Xiao Zheng, Huaiqing Zhang

Bulletin of Chinese Academy of Sciences (Chinese Version)

A composite system (CS) is an organic whole composed of multiple subsystems. It has the property of operating in a coordinated manner through the interconnection and interaction between its subsystems, which could be evaluated by the indicator of coordination degree of composite systems (CDoCS). However, there is currently a lack of quantitative methods for CDoCS and the CDoCS-based technology for composite system optimization. As a result, there is a lack of effective solutions to the problems caused by the disharmony of composite systems such as the mountain-water-forest-farm-lake-grass-sand systems (i.e., composite ecosystems) and the social-economic-natural systems. Therefore, the connotation of CDoCS …
