View Statistical Parameters

You can view the settings based on which Oracle Field Service collects statistical data. Some settings are duration parameters, travel time parameters, activity travel keys, and resource travel keys. Be aware that if you try to adjust the settings, it may significantly change the workload for each resource, and significantly impact the logic of gathering statistics for the work done.

In the Subsystems and Integrations section, click Statistics.

Field	Description
Duration parameters
Minimum relevant duration time in minutes Maximum relevant duration time in minutes	To ensure that outlier activity durations (sometimes due to non-compliance) don't adversely affect statistical calculations, durations with values less than or more than the minutes entered in these fields will be ignored by the statistics engine.
Lower limit for personal ratio to calculate duration (%) Upper limit for personal ratio to calculate duration (%)	The lower and upper limit percentages are about the company level duration for an activity. If the duration estimated for a resource’s assigned activity is beyond the lower or upper limit, the estimate is corrected so that it lies within the set limits. The Lower limit default value is 50 with an available range from 0-100. The Upper limit default value is 200 with an available range from 100-999. If the preference is always to use the personal learned duration without any lower or upper limits applied, the ranges must be set for the outer extremes with the lower limit set to 0 and the upper limit set to 999. Example: Suppose the company-level estimation for an activity is 50 minutes and the lower limit percentage is set to 80%. If the estimation for a resource is 30 minutes, the final estimation for the activity will be calculated as the maximum of 30 minutes and 80% of 50 minutes, which will be 40 minutes. The lower limit would be in effect and 40 minutes would be assigned to the activity.
Travel time parameters
Default travel average time	The average value and standard deviation (in minutes) used for travel time prediction when there isn't statistical data for travel between two specific travel statistics keys.
Minimum relevant travel time in minutes Maximum relevant travel time in minutes	To ensure that outlier travel durations (sometimes due to non-compliance) will not adversely affect statistical calculations, durations with values less than or more than the minutes entered in these fields are ignored by the statistics engine.
Airline distance method weight	This parameter defines the weighting proportion between the statistic (average travel time) and coordinate methods (straight line/airline) of calculating/predicting travel time between two locations. The options are as follows: 0 = Use only travel key based estimation. Oracle Field Service uses the statistics based estimation if coordinates are available. If not available, then it uses the default values. 0.001 = Prefer travel key based estimation. Oracle Field Service uses the statistics based estimation if coordinates are available. If not available, then it uses the airline distance. If even airline distance isn't available, then it uses the default values. 0.5 = Use both estimations evenly. 0.999 = Prefer Airline distance method based estimation. Oracle Field Service uses the airline distance based estimation if coordinates are available. If not available, then it uses statistics. If even statistics aren't available, then it uses the default values. 1 = Use only Airline distance method based estimation. Oracle Field Service uses the airline distance based estimation if coordinates are available. If not available, then it uses the default values.
Calculate airline distance based travel at key level	If this check box is selected, travel key parameters are used to calculate the airline distance based travel estimation. The application acts as before if this check box is deselected.
Default airline distance speed in km/h	The speed used to determine airline (straight line) distance time.
Default departure/parking time in minutes	The amount of time that's allowed for parking and departure from one activity to another.
Delivery Window Parameters
Delivery window factor	Determines how much deviation should affect the calculation of future delivery windows based on their ETAs.
Delivery window granularity	This defines the number of minutes to which delivery window values will be rounded.
Delivery window minimal size	When delivery window is calculated, this is the smallest value (in minutes) that will be provided.
Delivery window maximal size	When delivery window is calculated, this is the largest value (in minutes) that will be provided.
Delivery window should not start earlier than [ ] minutes prior to start of service or SLA window	Prevents the delivery window from starting outside the service window agreed to earlier. When the option is enabled, the statistically calculated delivery window can't start earlier than the specified number of minutes before the service window or SLA window start.
Stats Fields
Activity duration stats fields Activity travel stats fields Resource travel stats fields	This group represents the formation of the keys (made up of fields) used for the grouping of work duration and travel duration values to find the averages. The user-defined activity keys make it possible to sort the collected statistical data according to various activity characteristics, such as work order type, activity properties, activity postcode, etc.

Note: You can specify durations for specific activities and mobile workers through APIs. For more information, see the REST API for Oracle Field Service guide.
