航空機ヘルスマネジメント導入評価のためのシステムオブシステムズアーキテクチャ

This study proposes a system of systems (SoS) architecture of aircraft health management (AHM) to evaluate the cost-effectiveness of its introduction into aircraft maintenance of civil aviation. First, the SoS architecture is described to capture the interrelationship of the strategic capabilities required among the relevant stakeholders including manufacturer, airlines, and the regulatory authority by using the Unified Architecture Framework (UAF). Parameters to measure strategic capabilities and operational activities are identified, and those relationships are defined using parametric causal correlation using system dynamics approach. Then, the AHM performance, effect, and associated implementation costs are formulated and two patterns of AHM introduction are evaluated using the open operational data of Delta Air Lines. The results show that multiple AHM functions increase operational reliability, airline benefits and reduce the required number of mechanics.
