Table 6 Estimating the reliability of each truck sub-system using the parametric method
Truck sub-systems | Best distribution fit | Distribution parameters | Sub-system reliability (after 100 h) |
|---|---|---|---|
Engine | Log-normal | Log-Mean = 4.38 Lod-Std = 0.94 | 0.41 |
Transmission | Exponential | Mean time = 251.36 | 0.67 |
Hydraulics | Exponential | Mean time = 309.11 | 0.72 |
Body & Chassis | Log-normal | Log-Mean = 4.40 Lod-Std = 0.957 | 0.42 |
Gearbox | Exponential | Mean time = 461.14 | 0.81 |
