The technique for automation the process of maintenance schedules formation, optimize and adjust and equipment of manufacturing business units repair to reduce their carrying costs is proposed. The information flow of "maintenance planning" LGOK diagram in DFD notation is presented. The uniform loading of equipment and personnel as optimization of maintenance schedules criterion are selected.
