For them, adopting comprehensive and long-term maintenance strategies is just as vital to retain their competitive edge and ensure operational continuity 2. These companies could rely heavily on assets like IT infrastructure, transportation fleets, or physical facilities. In our increasingly complex and interconnected business landscape, even companies that primarily deliver services are often asset-intensive. The necessity of sustainable maintenance strategies is not confined to manufacturing or production-oriented companies alone. A robust analysis and monitoring system helps identify areas of improvement and track the return on investment in maintenance. These could range from metrics like ‘Mean Time Between Failures’ (MTBF), ‘Mean Time To Repair’ (MTTR), to overall equipment effectiveness (OEE). Justifying the financial commitment towards maintenance, especially preventive maintenance, demands measurable indicators of its quality and effectiveness. This understanding is crucial because these maintenance outcomes significantly influence the pursuit of business objectives like productivity, cost-effectiveness, and quality assurance. For asset managers and owners, it’s imperative to grasp how the results of maintenance procedures, which include reduced downtimes, extended equipment lifespan, and improved safety, interact with the inputs of various operations such as labor, capital, and resources. It serves as a key determinant of operational efficiency and longevity in any industrial process. Indeed, the role of maintenance extends far beyond simple repairs and upkeep. Whether producing goods or services, asset-intensive companies require sustainable maintenance strategies to remain competitive in the long run 2. In order for the investment in maintenance to be justified, the quality and effectiveness of maintenance must be measured 1. Asset managers and owners in modern times must understand the correlation between the outputs of the maintenance process and the inputs of various operations in terms of their overall contribution to business objectives. Maintenance is crucial for the long-term success of any industrial process. Since these circumstances frequently do not occur simultaneously, it is imperative for the business to give them significant consideration. If these parameters are not met, preventive maintenance can be a better option. Corrective maintenance is usually necessary in the case of small companies, significant impact on business or production plans due to failures, potential risks to public safety, ready availability of spare parts, and when production processes are not interdependent. Additionally, the paper incorporates various models and visual aids within its content to facilitate and guide the decision-making procedure. This paper primarily aims to present a comprehensive literature review concerning the strategic decision-making process for selecting the appropriate maintenance type under varying conditions. The scale of the business, the cost of machine failure, the effect of machine failure on the production schedule, the effect of machine failure on worker safety and the workplace environment, the availability of spare parts, the lifespan of the machine, and the manufacturing process are some of the factors that are covered in this paper. Given the importance of this decision, this paper discusses the optimal maintenance type under different conditions. For instance, preventive maintenance can be further classified as either predictive maintenance or periodic maintenance. ![]() All other classifications are encompassed within these two categories. ![]() ![]() The primary categorization of maintenance consists of two main types: corrective maintenance and preventive maintenance. This decision has a significant impact on the organization and its overall market sustainability. Selecting the appropriate maintenance type is a challenging task that involves multiple criteria working together.
