Determining the Optimum Number of Single Operator Controlled Unmanned Aerial Vehicles for NPP Monitoring Missions: Human Error Issues

An approach to determining the optimum number of single operator controlled unmanned aerial vehicles for NPP monitoring missions are suggested. The approach takes into account operator errors and wireless links equipment failures. In the approach, Human-machine system Operator - Fleet of unmanned aerial vehicles is considered as a queuing system. An example of using the approach to determining the optimum number of single operator controlled Spectator-M unmanned aerial vehicles for Zaporizhzhia NPP monitoring missions is presented. The results obtained are analysed and discussed.
