Dekker et al. (2008) proposed the following working definition of resilience: “A resilience system is able to adjust its functioning prior to, during, or following changes and disturbances, so that it can continue to perform as required after a disruption or a major mishap, and in the presence of continuous stresses”. The design, in terms of functions and resources, of a system with an enhanced ability to adjust to a dynamic environment, in order to timely ensure effective functioning and response to stresses and disturbances supersedes the content of current approaches in risk management. Based on their definition, Dekker et al. (2008) describe certain demands from the designing of resilient systems. These are: a) to ensure for the system appropriate adjustment functions, b) to ensure for the system continuous feedback that is critical for the interpretation of inherent and external conditions, c) to ensure for the system a certain level of ability to forecast, and d) to address to the system past experience in a lessons-learned mode.
