TRIP OD
2. CIRCUITY Trips
-
-
-
2.4 TRIP OD for multiple circuits with furthest point within all circuits - to consider the innermost circuit
2.5 TRIP OD for circuits with one or more lower points after the furthest point in which NOT ALL are permissible
2.6 TRIP OD for circuits with one or more lower points after the furthest point in which ALL are permissible
-
4. NORMAL
-
-
Itineraries containing side trips (where the farthest point is equal to the last point) - should be set as OneWay - Normal
3. RETRACTION TRIPS
3.1 All retraction trips with one or more lower points after the furthest point in which ALL are permissible
- Check for the Trip Type as well as Trip OD here
- trip type should be OneWay
- Ignore all previously touched points after the furthest point
- Ignore all points which are in same city/country/region country exception as that of the origin
- OD should be the last permissible point
3.2 All retraction trips with one or more lower points after the furthest point in which NOT ALL are permissible
- Check for the Trip Type as well as Trip OD here
- trip type should be Open-Jaw
- OD should be the last permissible point
Permissibility Check Logic
Derived using the DIST_RETRACTION data
In the DIST_RETRACTION table, find the record where dst_kms (OL) falls and pick the lower range record. Use the retraction_allowed and each_one values from that record to derive Curver Ratio
Circuity Ratio = OG + GL / OL
where O is Origin
G is Farthest point
L is the sector after the farthest point
-
If Circuity Ratio < Curve Ratio, then Permissible, Else not permissible
-
Note: There can be none, one or many lower points for which the permissibility needs to be checked.
Lower points which have been already touched before the farthest point or which belong to same country or region or region/country exception as the origin are not considered for permissibility check
