Abstract:

The properties and risk characteristics of grey rhinos have been deeply investigated and used, which are new emerging concepts and metaphor theories in risk management areas. To prevent and mitigate risks and challenges nowadays, it is urgent to systematically investigate the grey rhino-related contexts. The risk classification system, evolutionary mechanism, and management strategies of grey rhinos were explored by integrating existing theoretical models and risk classification approaches. The results indicated that the grey rhino risk was attributed to objective environmental factors and subjective cognitive factors. Moreover, the grey rhino risk can be divided into hidden, stationary, and collisional gray rhinos based on properties, cognitive, state, time, spatial, and subject perspectives. The risk development trend of each grey rhino species was evaluated based on the mechanism of risk perception, risk distance, and risk framework influence factors. Furthermore, an evolutionary framework of "accumulation-fluctuation-mutation" within a complicated system was proposed to develop risk management strategies and improve cognitive abilities by identifying hidden gray rhinoceroses that were not easily perceived. The innovative idea is strengthened to resolve static grey rhinos of normalized coexistence, and agile mode is created to deal with sudden bursts of collision gray rhinos.

Key words: grey rhino risk, classification system, evolution mechanism, risk management, management strategies
