An approach to resilience engineering in ATM is the high level objective of the SAFECORAM project. The approach proposed in this project eventually deals with the re-allocation of tasks between residual resources of the system after a disturbance, in order to minimize the system loss of global performance. Improving the resilience of the system is then translated in a minimization of performance decay in presence of failures, emergency conditions, disrupts of the ATM system. The description of the idea as a whole is presented in (Errico et al., 2014).
The ATM is an open system in the sense that its operation is constantly perturbed by disturbances. These disturbances may interact with each other, potentially creating a cascade of adverse events, that may span over different spatial and time scales. The adverse events in ATM may have different nature and impact ((Members. ”ComplexWorld, 2012) (Francis, 2013),): they may pass without any discomfort for passengers, they may result in a small passenger discomfort or they may produce a discomfort that is out of any proportion. In the latter case, there are two categories of events: catastrophic accidents involving one or more aircraft; events that affect the performance of the system. These events are rare and exceptional in ATM, but they have large economic and safety impacts, so they have triggered several studies. While the use of safety analyses of catastrophic events and of human performances has led to an ultra-safe ATM system, there are very few studies which address other performance parameters, such as capacity, cost/benefit and environment in non-nominal conditions. In the paper, an approach to the ATM resilience engineering, which integrates both safety and all other performance parameters (KPAs) of the ATM system, as identified in the SESAR performance Framework, is proposed. It is difficult or even impossible to establish the resilience role in realizing these high safety and high performance levels of the system. Currently, there is only aqualitative analysis of resilience assessment in ATM, and few quantitative approaches have started, only very recently, to be proposed in scientific literature (Herrera et al., 2014), so we are not able to assess whether an ATM system design is more or less resilient then another ATM system arrangement ((Members. ”ComplexWorld, 2012) (Francis, 2013),). The way we propose to escape from this situation is a systematic implementation of resilience in ATM, in SESAR and NextGen programs.
This paper deepens reference (Gargiulo et al., 2014). It discusses the design of the optimization methodology to support the resilience engineering problem as approached in SAFECORAM, with an introduction about the state-of-the-art of resilience management methodologies. In addition to what stated in the reference paper, in this work a relevant case study is introduced, and the paper reports the achieved experimental results obtained by using a suitable software environment. The proposed methodology demonstrated as promising for the application to resilience engineering of ATM system problem.
