Current activities
Dr John Ahmet Erkoyuncu, as part of his post-doctoral responsibilities is currently managing two projects. The first one focuses on developing an attribute trading tool, where the case company is Rolls Royce. The attributes (e.g. weight, unit cost, fuel consumption) refer to the key requirements for an aerospace engine. The trading takes into account the uncertainty and non-linear behaviour of the system. The key objectives of this project are:
- Defining the product and service attribute characteristics
- Designing requirements change: methodology development for the trade off study
- Uncertainty modelling and uncertainty impact analysis
The second project is part of a European consortium (VISION Advanced Infrastructure for Research) with over 20 universities participating. The project aims to create a European infrastructure that involves developing unique, visible and attractive information visualisation facilities for the relevant fields of environment, energy and health. John Ahmet’s focus is on building the external communication of the consortium.

Background
After conducting an MSci degree at Imperial College London in Applied Business Management, John Ahmet moved to Cranfield University in 2007 to conduct his PhD. The focus of his studies centred on integrating the influence of uncertainty into cost estimation at the bidding stage of Industrial Product-Service Systems (eg. Contracting for Availability). The research focused on the defence industry, where some of the organisations that he interacted with included BAE Systems, Rolls-Royce and the Ministry of Defence. In his PhD he developed the Uncertainty Tool for Assessment and Simulation of Cost, which has been implemented on a number of bids to guide with recognising the influence of uncertainty and to build this into the bid considerations.
John Ahmet is a member of the following associations.
- Association of Cost Engineers (ACostE)
- The Institution of Engineering and Technology (IET)
- The Risk Centre at Cranfield University
