Development of studies on fleet standardization and planning.
| Author | Main Findings |
|---|---|
| Borges Pan and Espírito Santo (2004) | Suggest an index for assessment of fleet similarity |
| Seristö and Vepsalainen (1997) | Found a negative correlation between standardization and maintenance cost |
| Zou et al. (2015) | Suggest that standardization may decrease unit flight cost |
| West and Bradley (2008) | Suggest that a more diversified fleet is more useful if you are operating in different markets |
| Kilpi (2007) | Found a positive correlation between standardization and profit margin |
| Brüggen and Klose (2010) | Released a positive association of standardization on operational efficiency |
| Merkert and Hensher (2011) | Suggest an LCC business model has no significant evidence of profitability |
| Barros and Peypoch (2009) | Presented that LCC companies have high efficiency and standardization |
| Zuidberg (2014) | Found that fleet standardization and operational performance are related positively |
| Zou et al (2015) | Suggest to use of standardization index would be efficient under some operational metrics |
