vehicle consumption caculation


I am trying to understand how the vehicle consumption figures are calculated (when clicking on the calculator symbol in equipment master). Because it doesn't look right to me.

On my test equipnment I following measurment documents: (Only two measuring documents exist)

*Date*             -*Tot KM* -    *Tot Liter*
01.07.2011    - 500    -           40
30.07.2011    - 1000  -           100

calculation method: Liters/100 KM

Short/long period days= 365

I am getting the following average values, I need your help to figure out how are these calculated?

Daily avg.cty:                17.24 (KM)
Daily Consumption:       2.07    (Litres)
AvgeConsumption:       12       (L/100 KM)

    Check this link

    1. Avg Activity :- 1000-500 /29days = 17.24

    2.Avg fuel consumped : 100-40/29days = 2.068

    3. Avg Consumption : 2.068/17.24 x100km =12

    • Hi,

      These short term and long term conditions are purely for analyzing the trend of vehicle performance.

      By default you will find short term as 30 days and long term as 365 days. This shows that the short term report gives the average data over the last month, ending with 30 days in the past, from the date you check this.

      The long term similarly gives the average data over the past year.

      The purpose is, as clearly seen, is to analyse the trend to know the performance of the vehicle - whether remaining constant or deteriorating.

      As Pushpa rightly pointed out, the respective measuring documents should be updated at least on a weekly basis, or whenever the refueling is done, which is the best way to have near accurate results.
