A multiple criteria evaluation of multi-family apartment blockʹs maintenance contractors: I—Model for maintenance contractor evaluation and the determination of its selection criteria

The paper presents a model that describes the process of selecting dwelling maintenance contractors. The model is based on a multi-criteria evaluation of maintenance contractors, the determination of their utility level for the buildingʹs users and a bid price in negotiations that are made according to the results of the multiple criteria analysis. The proposed model could further be applied to plan dwelling maintenance operations. The criteria of maintenance contractor evaluation are selected by taking into consideration the interests and goals of the buildingʹs users as well as factors that influence the process of maintenanceʹs efficiency. The correlation of the criteria characterizing maintenance contractors from various perspectives was determined.
