Sustainable maintenance planning in the petroleum industry: an application of system dynamics approach

Abstract

PurposeWhile the petroleum industry remains to be the main source of energy in the world, it is responsible for a large amount of resource consumption, environmental emission and safety issues. In this industry, most of the refinery equipment are running out of their designed life cycle, leading to many challenges regarding equipment reliability, products quality, organizations’ profitability, human resources safety and job satisfaction, and environmental pollution, which affects not only the human resources of the refinery but also the people who live in the vicinity. This study aims to model and simulate the maintenance system of an oil refinery to reduce the rotating equipment’s downtime while simultaneously considering the three pillars of sustainability.Design/methodology/approachConsidering the complexity of the system and its inherent dynamism, System Dynamics (SD) approach is applied to model and simulate the maintenance system of an oil refinery, aiming at reducing equipment’s downtime considering the three pillars of sustainability simultaneously. As a case study, the maintenance system of rotating equipment in the Abadan oil refinery of Iran is investigated.FindingsIndividual policies are investigated and categorized into three main groups: economic, social and environmental. The dynamic nature of the system demonstrates that applying combinations of the policies would be more effective than performing individual ones or even a combination of all policies at the same time. The findings show that to manage the maintenance and reliability issues in complex industries, only operational level maintenance strategies would not be helpful; rather, a holistic strategic solution counting different suppliers or even the government policies supporting the operational level maintenance decisions would be effective.Originality/valueThis study is the first which brings the perspective of sustainable policy-making in the SD modeling of a complex maintenance system like that of the petroleum industry. The developed model considers economic, environmental and social objectives simultaneously. Besides, it reflects the role of different stakeholders in the system. Furthermore, the policy-making attempt is not limited to the operational level corrective and maintenance solutions; instead, a comprehensive, holistic view is applied.

Maintenance work management process model: incorporating system dynamics and 4IR technologies

“…Chitongo and Pretorius (2018), Tokgöz et al . (2018), and Hosseinzadeh et al . (2023) successfully used mixed method incorporating system dynamics modeling to model projects execution dynamic behavior, airline MRO operations, and sustainability maintenance planning respectively.…”

“…Hosseinzadeh et al focused on sustainable maintenance planning in the petroleum industry using SD modeling with the aim to reduce equipment downtime. The study categorized individual policies into three groups, namely, economic, social, and environmental (Hosseinzadeh et al, 2023). Asim Tokgoz et al modeled airline maintenance, repairable and overhauls (MRO) operations using system dynamics approach to analyze decision scenarios (Tokg€ oz et al, 2018).…”
