Abstract: Carrier launching safety may be deteriorated due to ship motion. Judging errors by human experience are unavoidable for decisionmaking for carrier launching at proper times. Accordingly, the conception of a decisionmaking aiding system for carrier launching at proper times is proposed. By analyzing mechanism of the influence of ship motion on carrier launching, the vertical component of exit velocity is treated as a key parameter for evaluating launching safety. Rules of decisionmaking at proper times are established by taking into consideration the carrier launching operation procedure. Then a decisionmaking aiding system with neural network is modeled in combination with characteristics of the advantageous/disadvantageous launching time. The simulation results show that this system can effectively provide the launching officer with decisionmaking aiding information and improve carrier launching safety.
