...Mohamed Attia Purpose Balancing cost-effectiveness and availability against safety and environmental stewardship remains a persistent challenge in asset management. Conventional Risk-Based Inspection (RBI) often depends on imprecise qualitative assessments, while modern data-driven methods...

... the uncertainties/vagueness to much higher degree of accuracy in decision-making. The suggested framework is used to evaluate and select the optimal maintenance policy based on six different criteria namely safety factor, cost factor, maintenance factor, reliability, risk and added values. Findings The IF-AHP...

...-based systems reduces by 0.007491% and further diminishes. Risk analysis has presented applying an emerging approach called intuitionistic fuzzy failure mode and effect analysis (IFFMEA). For each of the stated failure causes, the output values of the intuitionistic fuzzy hybrid weighted Euclidean...

...Mohamed Attia; Jyoti K. Sinha Purpose The purpose of this paper is to analyze the reliability of the quantitative risk model used for planning inspection and maintenance activities. The objective is to critically discuss the factors that contribute to the probability and consequence of failure...

... maintenance contract relationships. The research design applies game theory to model the contract relationships using mechanism designs that are appropriate for problems with a moral hazard problem (Börgers, 2015). Mechanism designs assume that the principal is risk-neutral and the agent is risk...

The results also showed that integrating POE in the estimating process can provide more accurate cost estimate with high level of confidence...

... producers. To survive the competition, suppliers have to reduce maintenance costs, i.e. handle maintenance more efficiently. Risk analysis is one tool decision makers can use to help them prioritise as they plan maintenance actions. There are a number of different approaches to risk analysis. As the results...
