|
|
Monitor Weight
|
Real (kg)
|
The weight of the device without cladding.
|
|
Screen Size
|
Real (Inches) [Parts Count also]
|
The viewable image size of the device, measured on the diagonal.
|
|
Refresh Rate
|
Real (kHz)
|
The maximum horizontal scanning frequency of the device. This is the rate at which the device reads in data and refreshes the screen.
|
|
Power
|
Real (Watts)
|
Not required for the Hard Disk subcategory.
The maximum operating power of the device.
|
|
Life Time (L10)
|
Real (Hours)
|
Required only by the FIDES 2009 model.
Expresses product life by means of the L10 parameter, which corresponds to the time at which 10% of wearout failures occur. These failures are additional to so-called random failures that are modeled using the exponential distribution with a constant failure rate.
|
|
MTTP Preventive Maintenance
|
Real (Hours)
|
Required only by the FIDES 2009 model.
The mean or average time between two periodic preventive maintenance operations. When the maintenance policy does not include any preventive maintenance, the average failure rate is calculated over the average period between two corrective maintenance operations due to wear-out failure using the parameter values provided below.
|
|
Usage Rate
|
Real
|
Required only by the FIDES 2009 model.
The usage rate during the duration of the life profile specified by Life Time (L10). This value is the sum of the operating times divided by the total duration.
|
|
Shape Factor Ī²
|
Real
|
Required only by the FIDES 2009 model.
The shape factor for the Weibull distribution, which is used to model the wear-out type.
