Supplier evaluation in industrial power services: a case study in gas-turbine maintenance, repair, and overhaul

Abstract

The maintenance is one of the highest costs in a gas-turbine engine, after operating cost with approximately about 14-19 % of the total cost. Some of the operators do not have spare engines, and it will lead to operation shutdown. With the current market, most MRO challenged to provide their costumer to achieve quick turnaround time (TAT) at a low cost without affecting the quality of the product. Since MRO is selling the skill services, it took applied technology, skill training, and experience to deliver quality, which needs high cost. Therefore, MRO needs to collaborate with other parties (original manufacturer or others) to increase its capacity and capability. MRO should concern more for evaluating the vendors to align with the strategies to get quick turnaround time with the right quality product. Supplier selection is the objective of this research by analyzing the selection criteria at Industrial Gas-Turbine maintenance. The highest priority is the vendor effectiveness followed by the quality, cost, risk management. The highest weight is based on the priority of the supplier.
