    Nyckelord :;

    Sammanfattning : To minimize the unnecessary costs that arise when machines or other objects fail, perhaps needing to be replaced during less than ideal occasions through what is known as reactive maintenance, a more active maintenance policy through which objects are continuously maintained in a preventative manner based on life expectancy or from a cost-perspective, is preferred. Mathematical models can be advantageous to utilize when scheduling these maintenance occasion. LÄS MER
