WO-AHP-based risk assessment method for power coal supply chain of thermal power plant

The invention discloses a thermal power plant power coal supply chain risk assessment method based on an analytic hierarchy process (WO-AHP) of a sea image algorithm. The method comprises the following steps: firstly, identifying risks in a power coal supply chain and establishing a corresponding risk assessment index system; then preprocessing the obtained related data of the power coal supply chain; obtaining an objective function through a judgment matrix in an analytic hierarchy process, and substituting the objective function into a sea image algorithm to establish a thermal power plant power coal supply chain risk assessment model; inputting preprocessed data to obtain a weight and a consistency check value, and if not, adjusting the judgment matrix until consistency check is met; and finally, calculating scores according to the weights obtained by the risk assessment indexes of each layer, and judging a link with relatively high risk of the power coal supply chain of the thermal power plant.
