Multicriteria model to support maintenance planning in residential complexes under warranty

Building-maintenance decisions are a challenge for most builders. When builders finish construction, there is a guarantee period during which maintenance is their responsibility. These decisions have an effect that go 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. Thus, maintenance strategies should be devised with a focus on how to best deploy them to optimize both savings and occupant satisfaction. For this purpose, the present paper proposes a multicriteria 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 illustration of the application of the model is demonstrated, providing good results that support the decision maker in setting a better inspection policy.
