All stages of production of the value-added chain, production is increasingly caught between costs, quality, time and flexibility. Therefore the demands on maintenance increase. The evolutionary development towards Industry 4.0 presents new possibilities to meet these demands. Maintenance is an important enabler of the change to Smart Production according to Industry 4.0. To support this change, evolving towards Smart Maintenance is necessary.
Smart Maintenance stands for efficient maintenance and requires the following focus areas:
- Data Management
A large number of existing data generated by cyber-physical systems in the future provides an incredible potential for maintenance. In order to make the best of it, a data management needs to be carried out according to the aim. The right data not only allows predictive maintenance by means of a disturbance forecast but also allows the maintenance to be shown as a contribution to the value of the company.
- Knowledge Management
Demographic change and a shortage of skilled labor, as well as a change in the range of maintenance tasks required by Industry 4.0, call for a stronger focus on dealing with existing knowledge in the minds of employees. It is possible to find ways to externalize, store and transfer this knowledge to new employees.
- Learning Orientation
In the sense of a continuous further development of the Smart Maintenance, maintenance has to be aligned towards learning. This can only be achieved by integrating the essential steps into the control cycle of maintenance.
- Weak Point Elimination
Sustained removal of weak points, supported by Big Data Analytics and suitable IT systems for maintenance, planning, control, and analysis, becomes a central task of maintenance.
- Employee Qualification
The change to smart maintenance increases the technological, methodical and organizational competence requirements for employees working in maintenance. The change to Smart Maintenance can succeed only by precise qualification of employees and the development of specialists.
- Optimization of the Maintenance Strategy Mix
A major efficiency factor is the maintenance-specific optimization of the maintenance strategy mix. Depending on the requirements, this is composed of reactive, preventive, predictive and proactive measures. The diagram below shows a possible approach to optimizing the maintenance strategy mix. This is possible through the targeted use of condition monitoring and data analysis on previously identified critical systems. A dynamic adaptation of the maintenance strategy to changing conditions is particularly important.
