Investigators at University of Portsmouth Describe Findings in CDC and FDA (A Resilience-based Maintenance Optimisation Framework Using Multiple Criteria and Knapsack Methods).

A study conducted at the University of Portsmouth in the United Kingdom has developed a resilience-based maintenance optimization (RbMO) framework for asset management. The framework aims to absorb fluctuations in the operating context, such as business fluctuations and pandemics like COVID-19, while maintaining asset performance at an optimal maintenance cost and an acceptable level of risk. The framework utilizes the analytical hierarchy process (AHP) and the Knapsack method to define risk reduction and select maintenance tasks within the allocated budget. The approach also introduces the nested criticality grid (NCG) to visually represent risk profiles and facilitate decision-making. The research emphasizes the comprehensive continuous improvement cycle of the RbMO framework, which enables asset owners to effectively manage changes in the operating context.
