Purpose: This paper aims to propose a mixed approach for evaluating preventive maintenance performance based on anti-fragility factors in Iranian Gas Transmission Company (IGTC) district 10. Design/methodology/approach: In the quantitative part of this mixed research, using the Fuzzy Delphi Method (FDM), out of 131 key performance indicators taken from different standards, 16 indicators identified suitable for the activities of IGTC district 10. In the qualitative section, using the thematic analysis method, ten organizational and academic experts participated, and anti-fragility components in the form of 254 open codes, 18 organizing codes, and two comprehensive codes identified and categorized using Maxqda2020 software. The effect of these indicators on maintenance key performance indicators investigated using the canonical correlation method. Findings: Findings indicated that learning and growth, panarchy, heuristics, harmonization, and Barbell strategy of behavioural components, and redundancy, participation system, and high reliability of structural components had the highest impact on key maintenance performance indicators including condition-based maintenance cost, average downtime, percentage of accidents involving personnel, and the mean time between failures. Research limitations/implications: The most important limitation of this research is that due to the case study unique characteristics, the results could not be generalized to other companies. Besides, the proposed model developed based on anti-fragility factors that are not available simply or difficult to define for every company. So, it is suggested that in order to apply the proposed model, first the anti-fragility factors for the company should be localized. Practical implications: By applying the proposed model, companies can expect a significant decrease in the total preventive maintenance cost and human injuries caused by defects and breakdowns. Also, managerial planning in the preventive maintenance system toward the resource allocation to the equipment and PM personnel will be simple. Social implications: Recognizing anti-fragility factors and reducing irreparable human and technical damages will lead to positive employee and social attitude towards the company. Also, the proper performance of a preventive maintenance system will result in a clean and carbon-free environment. Originality/value The proposed approach is suitable for evaluating preventive maintenance performance based on anti-fragility factors in companies. The use of quantitative and qualitative analysis in the proposed methodology was not considered in the reviewed literature, simultaneously. So this approach can be a model for other subsidiaries in the oil and gas industry to follow.
