With stopduration calculation you can determine the total time of a single stop (1 or more activities of the same kind) more accurately, than by using a standard stopduration. Say you are going to load 5 shipments at the warehouse. 5 loading activities will be recorded in the trip. Say your loading activity has a standard duration of 30 minutes, this means 5 x 30 = 2,5 hours will be calculated in the trip for loading these 5 shipments. That is not realistic.
With stopduration calculation these activities will be seen as 1 stop, and depending on the number of shipments or loading meters or kiloes a certain stop duration can be set.
Stopduration groups can also be used in the time administration to determine the lenght of a certain activity from the on-board computer. For this see normalization groups in the time administration.
The stopduration group can be set in the screen Companies (tab sheet Planning), but can also be set per plan group on the tab sheet Extra parameters.
A stopduration group consists of 1 or more stopduration rules and 1 or more factors:
¶ Stopduration rules
Per stopduration group you set the stopduration rules. On the tab sheet Factors you can specifiy the duration when multiple shipments are transported within a trip. Loading 5 shipments normally wouldn't take 5 times as long as loading 1 shipment. That kind of nuance can be set there.
Overhead duration
The minimum duration that this stop takes.
Handling duration group
In the handling duration group you determine which group of volume related prices is applied to accurately determine the stopduration for a certain actitivy. This can be done per unit.
This easiest way is to make a volume related price based on payload. Therefore it is useful to set up a standard payloadcalculation and payload ruleset. But you can also make these based on any other units.
In the handling duration group you can also set a minimal and maximal duration.
The minimal duration is equal to the Overhead duration of the stopduration group.
Activity kind
The activity kind to which these duration applies.
Region
The region to which this stopduration applies.
Address
The address to which this stopduration applies.
Address kind
The address kind to which this stopduration applies.
Company
The company to which this stopduration applies.
Plangroup
The plangroup to which this stopduration applies.
¶ Factors
With factors you can multiply the stopduration you have set in the stopduration rules. You would use this to specifiy that some drivers unload faster than other drivers. By placing these drivers in groups (fast, slow) you can deviate from the calculated stopduration with a factor.
It is also possible to set unloading times to a longer duration in the winter than they are in the winter. Or that unloading takes longer when a certain trailer is used, because it (for example) has a slower pump (this would apply to tank transportation). Stopduration might also differ between regions or products.
Stopcontext
The applied factor depends on the stop context.
A stop context contains the conditions and when a stop meets these, the factor will be applied to the duration. This factor x might be 0.9 or 1.2.
