In order to improve the operational effectiveness of unmanned underwater vehicle (UUV), the UUV was analyzed. According to the characteristics of a certain type of UUV equipment, the matrix model of availability, dependability and inherent capability is established by combining ADC and AHP, and the operational effectiveness of UUV equipment is quantitatively evaluated. The results show that the analysis can be used as a reference for evaluating the operational effectiveness of UUV equipment, and can also provide support for the subsequent development of UUV equipment.
