The use of PLM tools is widely spread in the aeronautical industry. Although scheduling and line balancing have remained aside these tools for long, they are being developed in the recent years. They need to tackle with complex resource constrained scheduling problems. In this work we present a simulation model we have developed for evaluating the robustness of a baseline scheduling for an aero structure assembly line. To begin with, we have identified and quantified the main causes of the disruptions. Then we have created a discrete event simulation model of the production line to take everything into consideration, and then run several experiments to evaluate different production planning obtained with the different methodologies and the impact of failures in the deliveries of finished products. Also, different scenarios in terms of failure quantity and typology have been studied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
