To ensure the safety and serviceability of the structure, a lifetime maintenance program has to be planned based on result of the future prediction of structural conditions. Reliable of decided maintenance program depends on degree of uncertainty of the data used in the future prediction model. The method to determine the expected probability and cost of lifetime maintenance by considering parameters uncertainties of the prediction model is proposed. Example of material selection by using the proposed method to minimize the life cycle repairing cost is given. |
