Reliability analysis based on weibull distribution model for spreaders

摘要

Predicting fault and evaluating reliability are two of the most important tasks for the correct use of spreaders of the port container transportation [1]. With the historical fault data of the spreaders, it is confirmed that the failure time interval observes the Weibull distribution. The correlation coefficient method is used to estimate the location parameter, the shape parameter and scale parameter of the Weibull distribution. MATLAB GUI is used to develop the Weibull distribution parameter estimation tool based on the historical fault data and apply it to the actual spreader fault data analysis.
