The research of the difference measure method for risk probability distribution plays a key role in the early warning decision-making management of retail supply chain unconventional emergency. However, the common difference measure indices are established by the specific density function or distribution law of the risk probability distribution. In Knight uncertain environment, only the moments of the risk probability distribution can be obtained.
