Aiming at the problems of low evaluation accuracy and long evaluation time in the supply chain operation risk evaluation of logistics enterprises, a method of supply chain operation risk evaluation of logistics enterprises based on the Monte Carlo algorithm is designed. First, set up the screening process of logistics enterprise supply chain operation risk evaluation indicators, and determine the key risk evaluation indicators. Then, the relationship network of risk evaluation indicators is constructed and the evaluation indicators are pretreated. Finally, the reliability degree of the index i...
