Cost estimation in an aeronautical supply chain

Abstract

The Customer Support in an aeronautical supply chain is the key element, present throughout the cycle life of the aircraft for customer loyalty and ensure a business long term. Every order is different since each customer requires that their aircrafts respect particular specifications, then it is necessary to carry out an estimation cost of spare parts Service each time there is a certain request. At present the calculation process used in order to define The Spare Parts Service is an “Exact Estimation” method, through the OPUS10 Tool, very accurate, but extremely expensive in terms of time and processing time. Since, unfortunately, not all orders come to a successful conclusion, in the first negotiation phase (RFQ) it is possible to use an approximated calculation method allowing a great time and thus costs reduction. This paper goal is to search a mathematical algorithm, in a necessary approximation circle, that can substitute an exact method with a parametric estimation methodology.
