Multivariate manufacturing process planning for aircraft airframe production based on weighted criteria analysis

This paper deals with technological and operational aspects of manufacturing process planning for multiple values of decision parameters. A discrete parametric model is proposed to generate multiple process plans for a given or proposed production system. The model is based on generating graphs for possible manufacturing process operations and production system capabilities. An automated platform-based system is built around this model to generate and analyze multiple manufacturing process plans based on the chosen priority criteria. The analyses are based on estimating distances in constructed graphs and several sets of priorities for final assembly production systems as well as parts suppliers. Both manufacturing process selection and production systems architecture used in this model are specifically adapted for the aerospace industry.
