Abstract:Simulation of ship motion is becoming increasingly more viable as a method for estimating the value of parameters that can be used for design, life-cycle management, risk analysis, developing and validating operational tactics, training, etc. It is vitally important to be able to draw sound conclusions from the simulation results. An examination of the process for obtaining parameter estimates and the means of determining their reliability is key to evaluating the confidence that can be placed in the results and avoiding drawing inappropriate conclusions from the simulation results. An extension of Chebyshev's Theorem was developed to provide a robust general tool to provide a conservative estimate of the probability that the parameter is within a specific interval. In addition, a method for determining the number of simulation runs required is suggested.
