Due to the increasing complexity of plants (including their automation) and the introduction of process control systems, maintenance has often developed independently alongside production, causing conflicts from time to time. However, these are of no interest to the customer at all. The only thing that counts for him: on-time deliveries while maintaining the highest quality. The planning of maintenance activities should always be in line with advanced planning & scheduling (detailed production planning).
The efficient use of resources is the most essential aspect for companies, no matter whether a resource is an aircraft or a production line. The entire planning depends on its availability. Of course, both production and maintenance planning occupy the same resources. Thus, resulting occupancy conflicts should be planned in line.
