A Critical Review on Multi Criteria Model to Support Maintenance Planning

Building-maintenance decisions are a challenge for most builders. When builders finish construction, at that place is a warranty period during which maintenance is their duty. These decisions have an effect that goes beyond the financial aspects of maintenance costs, because failures during the warranty period are reflected in customer satisfaction and may have an effect on future sales. Therefore, maintenance strategies should be prepared with a focus on how to best deploy them to optimize both savings and occupant satisfaction. For this purpose, the present paper proposes a multi criteria model based on the delay-time concept to provide the builder with a quantitative tool to support the definition of a maintenance-inspection policy. An example of the diligence of the model is presented, providing dependable outcomes that substantiate the decision maker in determining a better inspection policy.
