A cost estimation approach for aircraft design enhancement

Abstract This paper presents a novel reliability-based parametric methodology for quantifying the reliability of cost estimates new composite aircraft components. In recent years, production sector has increased its attention on optimizing their manufacturing operations. It become clear that key factor in success these operations is consideration not only technical factors, but also economic ones as well are relevant. Composite variability greatly influenced by many and since with composites significantly more difficult than traditional materials, there sources uncertainty could influence Therefore, it worth considering during estimation process to quantify estimates. To demonstrate proposed methodology, numerical example featuring real-life component from Boeing 787, data, presented. Results show can associated components an effective manner, thereby supporting engineers optimising designs, helping them avoid errors budget definition, enabling allocate resources efficiently.
