Modelling in Optimal Inspection and Repair

A model for reliability based optimal inspection and repair strategies is described. The total expected costs in the lifetime is minimized with the number of inspections, the inspection times and efforts, the repair crack size limit and a design parameter as optimization variables. The equivalence o...

Description
Summary:A model for reliability based optimal inspection and repair strategies is described. The total expected costs in the lifetime is minimized with the number of inspections, the inspection times and efforts, the repair crack size limit and a design parameter as optimization variables. The equivalence of this model with a preposterior analysis from statistical decision theory is discussed. It is deseribed how information obtained by an inspection can be used in the repair decision process and to update the inspection plan. Stochastic models for inspection, measurement and repair actions are presented. Finally a smal! example is presented.
