The use of multiple, parallel-acting working units is becoming more common today especially when large parts and high working volumes within limited production and station times are required. In order to effectively maximize the higher working capacity of two or more units with machining, joining or assembling functions, a number of restrictions, including maintenance, breakdowns, available working space, etc., must be considered. This paper deals with new adaptive planning and optimization strategies, enabling the compensation of those effects. Results of a case study in aircraft component manufacturing are presented.
