    Affordability Assessment of Industrial Product-Service System in the Aerospace Defence Industry
    (Cranfield University Press, 2009-04-01) Bankole, O. O.; Roy, Rajkumar; Shehab, Essam; Wardle, P.; Rajkumar Roy; Essam Shehab
    The Industrial Product-Service System (IPS2) takes a whole life cycle view in order to consider the total cost of the IPS2 offering. This paper focuses on the concept of customer affordability which aims to review current practice in industry and with interaction between customer and solution providers to identify factors affecting affordability. It secures a standard definition and proposes a measurement technique called the Affordability Index (AI) within the aerospace defence industry. A preliminary Affordability Capability Audit Tool is developed to give an indication of the confidence level about the AI. It identifies challenges in industry and outlines opportunities for further research scope.

    Uncertainty challenges in service cost estimation for product- service systems in the aerospace and defence industries
    (Cranfield University Press, 2009-04-01) Erkoyuncu, John Ahmet; Roy, Rajkumar; Shehab, Essam; Wardle, P.; Rajkumar Roy; Essam Shehab
    Contracting for availability is expected to become more prevalent for product -service systems (PSS) in the aerospace and defence industries. These contracts tend to transfer responsibilities for the operational phase from the customer to the supplier. In parallel, with operational life spans spanning several decades, the ability to deal with uncertainty in cost estimation for support activities is becoming critical. This paper outlines challenges within this process derived from literature as well as issues that were highlighted during interviews with four major defence and aerospace organisations.
