AbstractState Railway of Thailand (SRT) is a public agency which has the responsibility for planning, constructing, managing, and maintaining railway network in Thailand. Due to the maintenance budget limitation, SRT has established the Railway Maintenance Management System to manage their railway network. SRT has conducted the cyclic maintenance and collected their railway inventory data and its condition data. However, the determination of railway maintenance management system is solely based on the inspected track condition data. However, an effective railway maintenance selection is the multiobjective decision-making process which is very complex and it is subjected to risk and uncertainty. This situation leads this study to modify the existing determination by applying the concept of objective function. The overall objective value is the summation of objective values for different objectives, influencing parameters, and their weighting factors which obtained from the Analytical Hierarchy Process (AHP). Moreover, some influencing parameter can be changed over time or beyond the control of agency. Therefore, the decision-making process may still expose to risk by invisible risky information. To address this problem, a framework which takes risk into account is developed for selecting optimal maintenance alternatives. Incorporation of risk analysis by considering the inputs variables in the form of probability density function (PDF) then simulated by using Monte Carlo simulation technique. The result of a risk-based decision-making process can help SRT determine the optimum maintenance alternatives those are targeted towards maximizing benefits and minimizing cost under risk control. Finally, Northern and Eastern routes are selected to present as a case study of an overall risk-based decisionmaking process
