Cost Model for Assessing Losses to Avionics Suppliers During Warranty Period

State of the art in Through-life Engineering Services

“…When organisations seek to adopt TES solutions the need for effective cost modelling to ascertain and mitigate risk becomes evident. This is clearly identified within the literature by Pour et al [106], Baguley [107], Kirkwood et al [66], Raza and Ulansky [108], and Erkoyuncu and Roy [65]. These authors all offer alternative modelling techniques that can assist in developing the understanding of risk associated with, and due to, cost when adopting TES strategic initiatives.…”

“…Nonaka et al [37] [146] [147] [146] remain significant contributors reporting on models in support of service and availability for use of machine tools whilst Toossi et al [86], van Dongen [115], Norris [85], Lingegard and Lindahl [117] offer models and the case for their application in the Rail Sectors of the UK, Sweden, and the Netherlands. Upon review it is observed that contributions relating to the generating of models within TES include the calculation of remaining useful life and MRO decisions [148] [149] [150], logistics [151], cost [67] [66] [108], obsolescence [152] [109] [153] and Inventory [151] [154] and all such contributions feature significantly.…”

“…A cost modelling technique was also used to reduce expected warranty costs by determining financial losses to all components during the warranty period of avionics products. They considered warranty, reliability and maintenance as key indicators contributing to the minimisation of these losses [108].…”
