Aiming at the problem that existing ship combat readiness assessment methods cannot meet the needs of naval mission support, a ship combat readiness assessment method based on cloud model theory is proposed.

First, in the process of determining the index, based on the cooperative game weight method, the weights calculated by the analytic hierarchy process, entropy weight method and grey correlation method are used for the cooperative game in order to fit the combined fixed weight, and variable weight theory is introduced to modify and optimize the fixed weight. The cloud model theory is then introduced, and a fuzzy comprehensive assessment model based on the cloud model is designed using cloud similarity instead of membership degree. Finally, taking air defense tasks as an example, the combat readiness of the ship is assessed.

The simulation results show that under the variable weight mode, the fuzzy comprehensive evaluation results based on the cloud model can more accurately reflect the combat readiness of real ships.

The results of this study can provide references for ship combat readiness assessment.
