Lessons from the application of a resilience engineering based assessment method to evaluate the resilience of a train departure and arrival management system

Abstract : Resilience Engineering is an original approach on safety management considering the development of agent's adaptive capacities to the diversity of situations that can occur, as the main target of safety management practices. The Resilience Analysis Grid aims supporting the assessment of key capacities of a resilient organisation. A specific instance is developed for supporting railway safety management. It is composed of a set of key indicators and a methodology to collect and analyse information. Application of the prototype to study trains station resilience capacities demonstrate its potential to understand resilience capacities with deducting resilience and fragility factors. between reality and artifice (Chandlers 2014). Consequently , the Resilience Engineering perspective on safety aims to change the main focus of safety management from risk prevention to workers adaptive capacity to respond and overcome unwanted situations. This perspective considers that the absence of unwanted consequences is not caused by the efficiency of risk barriers but by the capacity of the system to be in control despite the variability and the complexity of situations and the lack of time, knowledge, competence or resources (Hollnagel and Woods 2006). The Resilience Engineering perspective on safety management considers resilience of a system as it's "ability to recognize and adapt to handle unanticipated perturbations that call into question the model of competence, and demand a shift of processes, strategies and coordination" (Woods 2006) and "the intrinsic ability of a system to adjust its functioning prior to, during, or following changes and disturbances, so that it can sustain required operations under both expected and unexpected situations" (Hollnagel 2011). Aims of this paper are to firstly present indicators defined to assess the resilience of an organisation , then associated method for assessing resilience performance and finally results of its application to a train station. 2 PERFORMANCE INDICATORS According to the resilience engineering perspective on safety management, organisation can be con-1 INTRODUCTION
