| Abstract: | In this papaer, evolutionary algorithm is taken as optimization method, cumulative fatigue failure probability as limiting condition, survey cost as objective function, survey time interval and means as variables, respectively. According to fatigue characteristics of hull structure, the optimization research of fatigue strength deterioration survey is carried out, an optimal survey planning with minimal survey cost is chosen and a computation example is given. |
