Efficiency factors

LN uses efficiency factors to take into account variable daily capacity for lead-time calculation.

Various reasons can exist for variability in daily capacity: reduction of work force in the holiday season, or hiring extra work force in busy periods means that there is more or less plan time available on a specific day.

Note

The default value of the efficiency factor is 1.0.

Defining efficiency factors

You can define efficiency factors when you set up a calendar in the Calendars and Periods module of Common.

ToUse
Define a default efficiency factor for a working hours type.Working Hours Types (tcccp0103m000)
Define the default efficiency factor for a particular day of the week.Workweeks (tcccp0105m000)
Define an efficiency factor at recurring dates.Calendar Exceptions (tcccp0144m000)
Overwrite a default efficiency factor on a particular date.Calendar Working Hours (tcccp0120m000)
Change the efficiency factors for multiple calendars and availability types.Update Efficiency Factor and Capacity (tcccp0225m000)

 

After you change the efficiency factor, you must update the calendar by:

After you changed the efficiency factor, update the calendar by using the Update Calendar Working Hours (tcccp0226m000) session, or by clicking Update Calendar in the Calendar Working Hours (tcccp0120m000) session.

To view the effective availability factor on particular dates, use the Calendar Working Hours (tcccp0120m000) session. Remember to update the calendar.

Using efficiency factors

LN uses efficiency factors for the following purposes:

  • To take into account that resources can sometimes work more efficient than the average. For example, if a particular employee works harder in the morning than in the afternoon, you can enter an efficiency factor of 1.1 for the calendar line with time interval 09:00 - 12:00.
  • To take into account that, if you hire additional resources to perform the work, the lead time of operations shortens.
Note

Do not confuse efficiency factors with capacity percentages:

  • Efficiency factors affect the lead-time calculation for which the corresponding calendar is used: these factors influence the speed at which the work is carried out.
  • Capacity percentages provide information about the utilization rate of a resource.
