A study on the multi-hierarchical maintenance system of electrical demand facilities for building intelligent

Large modern buildings have multihierarchical maintenance systems to control the facilities in them. The article considers especially the maintenance of electrical facilities. This is usually the job of a person in charge, but if the person in charge is insufficiently experienced in management work, he can´t promote the efficiency of maintenance works in electrical facilities. In this paper, we´ve developed the multihierarchical maintenance system that processes maintenance data of electrical demand facilities. The maintenance system is an optimum control software package for building electrical facility
