Abstract
Service orientation in the defence and aerospace industries through availability contracts is creating challenges in cost estimation due to uncertainties. The chapter initially presents the topic of uncertainty in service delivery, which subsequently leads to a classification of uncertainties. Then, the current uncertainty-based service cost estimation processes are explained. By identifying the existing challenges, an improved framework to estimate costs is highlighted. This firstly involves enhanced understanding of the influence of uncertainties and cost estimation capabilities through the analytical hierarchy process and the Numeral, Unit, Spread, Assessment and Pedigree (NUSAP) Matrix approach. Secondly, it involves using agent-based modelling to represent the dynamism in service cost estimates. The chapter ends with a case study application of the approach.
