The level of electricity consumption per capita in Indonesia has increased by 6.6% per year on average within 2009 to 2019 and is predicted to grow until 2060. Therefore, the importance of transmission system reliability has been escalated to secure the fulfillment of electrical energy needs. A good maintenance strategy needs to be carried out in order to ensure the reliability of transmission system, one of which is through implementation of asset health index. This research aims to propose a framework that combines the Failure Mode Effect Analysis (FMEA), Analytic Hierarchy Process (AHP), and Simple Additive Weighting (SAW) methods to obtain a mathematical model of asset health index. Case study was conducted at PLN UIP3B Sulawesi in order to formulate health index model for medium voltage cubicle through quantifying the opinions of experts and practitioners in the field of 20 kV cubicle maintenance. The conclusions obtained are: 1) the use of framework based on FMEA, AHP, and SAW is able to produce multicriteria decision making model through objective quantitative approach; 2) the framework can be used as a tool to convert qualitative opinions into a series of quantitative weighting factors; 3) the framework was successfully applied to the case study of formulating cubicle health index model in UIP3B Sulawesi; 4) the framework has a good level of scalability so that in can accommodate further addition of other expert opinion in the future.
