The accidents of many share-control engineering application, including the aircraft carrier-landing process, are directly related to human error. In order to identify human error and assess the reliability of Human system interaction (HSI) in carrier landing, a control theoretic based simulation method is proposed. The simulator combines the pilot control with the cognition model that exploits the human error mechanism to describe the dynamic characteristics of carrier-landing. And the Performance shaping factors (PSFs) are also taken into consideration to represent the likelihood of human error. Moreover, the mission reliability is proposed as an appropriate metric of HSI. By quantitative simulation, the human error produced in HSI could be presented and demonstrated dynamically. The performance of the proposed method is tested through a case study.
