Replacement and imperfect repair of deteriorating system: Study of a CBM policy and impact of repair efficiency

This paper studies a condition-based predictive maintenance policy in the presence of imperfect repairs for deteriorating systems. The effect is assumed to be random sense that action reduces systems degradation level by proportion. associated distribution allows characterizing repair efficiency. As an example, beta considered. It defining wide range efficiencies. A with aperiodic and inspection planning considered new decision criterion introduced evaluate extent which would beneficial. aim find proper balance between replacement preventive leads optimal cost. With this consideration, cost model developed from regenerative semi-regenerative properties. expected evaluated reached as function Finally, numerical study drawn up demonstrate implementation highlight potential benefits proposed methods. sensitivity analysis on critical parameters also performed.
