Resilience is a concept that is at the forefront of recent discussions about the management of socio-technical systems. By most definitions, resilience is defined as the ability of a system to persist when exposed to adverse conditions or external stressors. The system is able to persist in the face of these stressors and adverse conditions due to three internal capacities: absorptive capacities, adaptive capacities, and transformative capacities. In complex socio-technical systems, it can be difficult to diagnose which of these capacities are responsible for the system's persistence. Furthermore, resilience research struggles to answer whether all forms of resilience would be desirable for improving the performance of socio-technical systems, and practically, can the understanding of specific resilient capacities be translated into useful management recommendations for these systems. Current resilience measurement approaches suggest using a single metric to measure resilience. This leads to debate around which metric might be the most appropriate to use when measuring resilience. Resilience has not been measured directly using the current approaches, it is measured by proxy metrics. This research program will outline a plan to develop a framework that measures resilience in a way which will allow researchers and practitioners to more precisely investigate resilience in socio-technical systems. The framework will provide an approach to distinguish between the three capacities of resilience. This should lead to amore informed and targeted discussion of implications arising from the measurements. This research will also couple functional system modeling to the measurement framework to enhance the tractability of these systems. The functional resonance analysis method (FRAM) will be used to develop the functional models. The coupling of functional system modelling with an improved framework for resilience quantification will enrich the study of this resilience in socio-technical system and provide an opportunity build improved resilience-based management strategies. The methodological developments in this research proposal will be tested by applying them to the Geriatric Medicine System in Newfoundland and Labrador. This system is an ideal socio-technical system for data collection activities and the testing of the methods developed in this research. The Geriatric Medicine System is a large, multi-stakeholder system that spans many disciplines. The functional modelling approach will help decipher this multi-stakeholder system, provide structure to the system, and improve tractability. Seven HQPs will be trained in this research program. HQPs in this project will gain skills in conducting experiments with human participants, investigative methods for socio-technical systems, and learn how to assess resilience in industrial safety contexts. The research area provides an opportunity for HQP to contribute to both, published literature and practice.

复原力是最近关于社会技术系统管理的讨论中最重要的一个概念。根据大多数定义，弹性被定义为一个系统在面临不利条件或外部压力时持续存在的能力。由于三种内部能力：吸收能力、适应能力和变革能力，该系统能够在这些压力源和不利条件下坚持下去。在复杂的社会技术系统中，可能很难诊断出这些能力中的哪一个是系统持续存在的原因。此外，复原力研究的斗争，以回答是否所有形式的弹性将是可取的，以提高社会技术系统的性能，并在实践中，具体的弹性能力的理解可以转化为有用的管理建议，这些系统。目前的复原力衡量方法建议使用单一的指标来衡量复原力。这导致了关于在衡量弹性时使用哪种指标可能最合适的辩论。复原力还没有使用目前的方法直接衡量，而是通过代理指标来衡量。该研究计划将概述一项计划，以制定一个框架，以使研究人员和从业人员能够更准确地调查社会技术系统中的弹性。该框架将提供一种区分三种复原能力的方法。这将导致对测量结果所产生的影响进行更有见地和有针对性的讨论。本研究也将耦合功能系统建模的测量框架，以提高这些系统的易处理性。功能共振分析方法（弗拉姆）将用于开发功能模型。将功能系统建模与改进的弹性量化框架相结合，将丰富对社会技术系统弹性的研究，并为建立改进的基于弹性的管理战略提供机会。本研究建议中的方法学发展将通过将其应用于纽芬兰和拉布拉多的老年医学系统进行测试。该系统是一个理想的社会技术系统，用于数据收集活动和测试本研究中开发的方法。老年医学系统是一个跨越许多学科的大型多利益攸关方系统。功能建模方法将有助于破译这一多利益相关者系统，为系统提供结构，并提高易处理性。 七名HQP将在该研究计划中接受培训。该项目中的HQP将获得与人类参与者进行实验的技能、社会技术系统的调查方法，并学习如何评估工业安全背景下的弹性。该研究领域为HQP提供了一个为已发表的文献和实践做出贡献的机会。
