Research Abstract |
(1) A stochastic and statistic model for the onboard monitoring data analysis was developed with the combination of the independent component decomposition and the conditional probability density function. (2) The proposed stochastic and statistic model was validated through the analysis of voyage simulation data and onboard monitoring data. The statistical accuracy was also clarified. (3) The estimation method of ship service performance was proposed by the proposed stochastic and statistic model and its application was concluded.
