Abstract :The aim is to analyze the alternative spare part stock level solutions for different operational scenarios and operational tempos for a generic Fighter jet product for different customers. It is aimed to use evidence-based decision-making methods for cost effective life cycle cost starting from design to the end of life for the life cycle sustainability case study. There are different methods for life cycle cost analysis and we decided to use OPUS decision tools suite for this case study. Various Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR) values were estimated and how strategic decisions should be made for changing situations were discussed with case studies. OPUS10 cost effectiveness analysis based on different Campaign Scenario alternatives. It has been shown that different cost-effective solutions for life cycle cost starting from design during life cycle can be achieved for stock levels and warehouse levels for different cases. The study was prepared for a generic fighter jet product and is original in terms of providing support to the decision makers for making strategic decisions for the supportability system. Strategic decisions include; stock-levels, depot levels, transportation, supply and maintenance plan.
