NZSEE Seminar Intersection of risk, reliability and resilience

Описание: Intersection of risk, reliability, and resilience

Risk has become a well-established discipline in both public and private sectors. Risk standards, processes, methods, data sources, and roles in organisations are focused on consequences of being unable to handle disruptions. Meanwhile reliability has focused on the quality of an organisation’s assets to reduce unacceptable interruptions. The discipline of asset management and increasingly the use of strategies, methods and techniques from reliability engineering, are improving the operational reliability of engineering systems and mitigating risks identified in risk assessment.

Although the field of resilience is long-lived, the discipline itself is not very well established. Its focus is the continuity of services by absorbing and adapting to hazards and threats. It needs the insights from risk and reliability engineering but is broader in scope. Resilience recommends proactive action to minimize harm and cost by using insights from data science, from scenario modeling, from digital tools/algorithms, etc. The need for collaboration and data sharing across organisations is a prerequisite for timely and least cost interventions. This has profound implications for organisations whose ambitions include resilience, and for the myriad of stakeholders in government, investment, digital solution providers, etc. who will benefit from the field of resilience.
