Abstract
Maintenance is one of the largest contributors to the expenses of the total ownership cost of complex aerospace systems. As technology is aggregated to modern systems, maintenance may become more costly and therefore more relevant when designing new aircraft. The present work investigates the cost-effectiveness of complex aerospace systems through case studies. Availability and life cycle cost are determined using commercial off the shelf optimization software package for baseline analysis as well as modifications in system maintenance design. By exploring design for RAM (Reliability, Availability and Maintainability), this research aims to reduce maintenance costs throughout the product life cycle and improve system availability while maintaining the system´s capability to fulfill its operational requirements. The optimization software is also used to quantify gains in cost reduction, aspect yet to be explored in depth in recent literature.
