This book provides methodological support for the strategic and operational planning and management of maintenance for industrial and infrastructure facilities. Maintenance measures play an important role in the safety, reliable production capability, and value preservation of facilities. The objectives of maintenance are derived from economic planning and reflected at the technical planning level. Practically tested concepts for organizational structure and processes complete the information. The work is particularly aimed at managing directors and heads of finance, controlling, technology, and maintenance, and includes proven checklists and overviews. The second edition addresses the digitalization of maintenance in a new chapter, presenting the associated innovation potential and challenges.
