Bayesian design in queues: An application to aeronautic maintenance

摘要

A Bayesian approach is presented for assessing efficiency is an queuing system with s spares. Maintenance scheduling and machine repair times are crucial in all industrial and business branches which depend on the correct performance of a set of machines. Inventory problems require quick replacement of broken down machine to guarantee continuous functioning. Optimal planning of resources becomes essential then to assure some operational performance level. Some interesting papers in this context are Iravam et al. (Ref. 1) in manufacturing, Almasi and Sztrik (Ref. 2) in telecommunication, Erkip (Ref. 3) in transport and Schoeming (Ref. 4) in semiconductor manufacturing. The Bayesian framework allows us to derive natural performance criteria in terms of the number of working machines. The queuing system can be designed by choosing suitable numbers of repair crews and spares such that a certain acceptable global performance is achieved, with guarantees optionally assessed by predictive or posterior distribution.
