Value Analysis of Engine Maintenance Scheduling Relative to Fuel Burn and Minimal Operating Costs

The paper presents the results from a study in collaboration with an airline that looked at modeling the relationship of maintenance and fuel burn costs relative to minimizing the life cycle cost relative to schedule. The work has verified that the bucket theory presented in the paper is a correct and has a direct impact on the scheduling interval. Ultimately, it was found that the maintenance schedule at the collaborating company was overly long and could be reduced by 15-20%, to reduce total costs in the longer term. The Genetic-Causal Approach was used in the cost modelling process and incorporated into the Value Operations Methodology. Consequently, the generic relevance of both these theories has been validated through the work presented.Control & OperationsAerospace Engineerin
