Aircraft Performance: The Effects of the Multi Attribute Decision Making of Non Time Dependant Maintainability Parameters

The aircraft maintenance is a complex and costly procedure (12-15% of total annual company costs). In this paper, aircraft maintainability was investigated by multi-attribute analyzing of non-time dependant parameters. With the aim of defining aircraft maintainability rank, the modified MAXMIN method was developed. The research was realized on the sample of five representative regional aircraft: Do328JET, CRJ-200, ERJ145, ATR42 and Fokker 50. The results obtained would help determine airline’s fleet.
