FastCost Switches and Descriptions

The following switches are found in the Trace Options dialog box in the Schedule Server application expanding the Switches > PASS > SchedSrv > Deadhead folder.

Table 1. FastCost Switches and Descriptions
Switch Description Default
Depth Fail Limit Enter a number to define the Depth Fail Limit, which will stop re-costing if re-costing has failed—in a row, more times than the Depth Fail Limit. Set to 0 for no limit. OFF
Depth Fail Rule If Depth Fail Rule is 0 then Depth Fail Limit only applies after at least 1 re-costed solution is found. If 1 then Depth Fail Limit applies even when no valid recosted solutions are found. OFF
Distance Formula 0=Fast Triangulation (default), 1=DCES Relaxed Cache, 2=DCES Zonal Cache OFF
Return Raw Results Specifies whether Fast Costing results are listed in the trace log without showing re-costed results. Used for analysis of Fast Costing results.
Specify one of the following:
  • OFF - Both Fast Costing and re-costing results are returned in the trace log.
  • ON - Only Fast Costing results are returned in the trace log.

OFF
Speed Factor The factor by which the average speed is multiplied when calculating travel times using Fast Costing. It is desirable for Fast Costing not to underestimate the speed since valid solutions might be missed. The value is the factor times 100, where 100 means a factor of 1, and 120 means a factor of 1.2. Values in the range of 100 to 120 are recommended. 100
Trace Statistics Specifies whether statistical information about Fast Costing efficiency is traced to the log during batch scheduling and single inserts.
  • OFF - Fast Costing efficiency statistics are not listed in the log.
  • ON - Fast Costing efficiency statistics are listed in the log.

To display additional trace settings, set the PASS > SchedSrv > Search > Trace switch to 3 or 4.

OFF
Use as Distance Method Specifies whether all final distance and travel times are calculated using the same formula that is used in Fast Costing. Useful only for analysis of Fast Costing performance.
Specify one of the following:
  • OFF - All final distance and travel times are not calculated using the same formula for Fast Costing.
  • ON - All final distance and travel times are calculated using the same formula for Fast Costing.
OFF
