Truck Cycle Time

Trucks, Cycle Time, by Area (#611)
|
|
Why:
You need calculate your truck cycle times for blocks in an area.
The report also will calculate cycle times for contractors that haul on a
24-hour clock.
Focus:
Focus of Report is to show truck cycle times. A cycle is defined as the
time to complete a round trip between a block and the mill. This provides
data of the length of time it takes to complete a round trip between a block and
the mill. It also allows you to determine any abnormally long (e.g..,
doddling drivers) or short trips (e.g.., speeding drivers). This report
shows the cycle times grouped first by block/destination combination and then
provides subtotals by truck with the group.
- Report covers all loads delivered by each truck
- The report will group cycle time averages by block and Destination, so
that the averages will be those reported for all Block/Destination
combinations.
- A configuration flag allows the report to be calculated using the entry
time (Time In) as the time entry for calculating cycle times. The
default value is Time Out.
- No payment detail is reported.
A cycle starts at the time a truck first leaves a mill yard (Time
Out). The cycle ends when the truck comes back and next leaves the
yard. Unlike cycle time reports #602 and #603, the process in thus
report is
not calculated on a daily basis, in which there is an assumed
break at midnight each day. (In those reports, the first trip of the day
never counts, it only serves to determine the first exit time of the day.)
The calculation method used here allows you to calculate the cycle times whose
yard exit (or yard entrance) times span midnight.
Instead of using midnight a
break, this report uses a maximum trip time to establish a break. In other
words, if the time difference between exit times is too long, it is assumed a
break has occurred. Therefore, the observation is not counted and is
treated like the start of the day. Basically, this approach drops all
cycle time observations whose times are too long.
How is the maximum trip time determined? The default maximum trip time
is set as an item in the Basic Setup window:
The 'Default Max Time' is the maximum trip time. All cycle times longer
than that value are dropped. The default value for this time is 12 hours.
Note also that you set whether you want to use the 'Time In' or 'Time Out' of
the Yard to use for the trip time calculations.
If the default value is too general, you can override the default with a
block specific maximum trip time. In the block setup wizard there is a
step that allows you to enter a maximum trip time for the block:
This is the same step that you would use to enter your on and off highway
distances for purposes of the BC fuel rebate calculation. This grid allows
you to enter a maximum trip time for the block -- this maximum time sets the
standard by which cycle times are compared to determine whether or not they
should be counted.
Selection Window:
The selection window allows you to filter the report by:
- Date Range: You can either select a pay period, or you can simply enter the start and end date directly into the selection criteria window. The Period selection is merely a short-cut for entering a date range, so you can always edit the start and end dates to be any date you choose. For example, you can pick a period defined as 8/1/2004 to 8/12/2004, and then extend the end date by three days to 8/15/2004. If you leave the end time blank, the program will assume you want the entire day for the end date. In the example below, the start date/time is 8/1/2004 00:00:00 (a blank is assumed to be time 00:00:00) and the end date/time is 8/15/2004 00:00:00. Because the end date time is blank (or 00:00:00), the program assumes you want the whole day of the 15th and makes the end date/time 8/16/2004 00:00:00. In the selection query, the program returns records whose start date/time is greater than OR equal to the start/date time and strictly less than the end date/time.
- Note: for report information that is based on load tickets, the report uses the Date Out (not the Date In).
- Area: You can select any or all of your areas (an area is C_Part_1
and may be referred to by another term in your system's set up.
- Block: You can select any or all of your blocks. If you select
a block that is not in one of the areas you select it will not be
included. Thus, if you want to select all the blocks in an area, just
select that area and then select all blocks -- those not in the area will be
dropped.
- Summary Data Only: Provides output (See Example Report 1) that can
be used directly to fill out the Off-Highway Worksheet.
- The "Only Print Raw Data" option generates a report with the
report detail, but with no subtotals or totals.
- The 'Show Rev/Hour' option shows the revenue that you specifically earn
for trucking. (This option is only useful if you are paid for trucking
as a distinct pay phase.) The report will calculation the Rev/Hr as
the revenue you earn divided by the truck cycle time, yielding a measure of
your implied hourly earnings, even though you are not actually being paid by
the hour.
Detailed Description:
The selection criteria determine the date range and blocks that appear in
the report. The report is based on your loadslip entries.
The report shows the loads delivered from each block
For each load, the columns are:
- Block Code: Source block
- Destination: Destination of the load
- Truck Code: Truck code (number) for the load
- Date: Date of the load
- Ticket: Load ticket number
- Prev Time Out: Previous yard exit time (previous load of the day)
- Time In: Entry time of the truck out of the yard of the current load
- Time Out: Exit time of the truck out of the yard of the current load
- Yard time: Time between entry and exit of the yard
- Trip time: Round trip time -- equals time between Prev Time Out and
Current Time Out
- In Avg: Is the trip in the reported average for the truck (Y = yes;
N = No)
- Cause: Reason load is not included in the average, such as the
cycle time for the load exceeds the maximum trip time.
- Revenue/Hr (Optional): This column shows the revenue earned for
the trip divided by the round trip time. The revenue earned for the
trip is the amount that you were paid by the mill specifically for the
trucking phase for the load, regardless of the pay basis (per unit of weight
or volume or by load)
The truck averages are reported for yard times and trip times. The
report will group averages by block and destination, so that the averages will
be those reported for all block/destination combinations.
Key Notes:
- The report treats 'split' loads as individual loads. The report does not use the load count field on the load slip.
- The report does not differentiate between header 'H' and detail 'D'
load records.
- You must have load revenue entered for the trucking phase in order to make
use of the Revenue/Hr column.

The summary view shows the average cycle times by block and destination for each truck and also
a total cycle time for each block and destination
for all trucks together. The above report is for two block/destination combinations and shows all the trucks that
hauled loads off those blocks. |
