Abstract
The present study develops a method for the sake of evaluating Disposal and Recycle (DaR) cost in view of the increasing demand in aircraft retirement. Firstly, a process model is extracted. The subordinated cost elements are also identified. Next, the cost aggregations based on the DaR process steps are discussed. Moreover, it proposes an economic indicator to support the determination of the aircraft DaR strategies. The indicator is used to evaluate the economic performance and to facilitate the trade-off studies among different DaR scenarios. This analysis is demonstrated on two aircraft types with two scenarios. In addition, sensitivity analysis evaluating the impact of the salvage value, residual value, DaR cost, and the learning factor is performed. It is found that the engine DaR possesses more economic gains than that of the aircraft. The salvage value and residual value are the main factors which influence the DaR economic performance.
