Hi All
I have small query about the Takt time is calculation.
In our project the Takt time is calculated as follows
Takt Time = Available Production Time / Customer Demand
Takt Time differs from Cycle Time, which is the actual time it takes to make one unit of production output Ideally Cycle Time is less or equal to Takt Time,
Ideally Cycle time is less than the Takt time so that it can meet the customer demand.
So if we have demand of 400/month and the available capacity of resource is let's will be 20(Days)*24 (hrs)*60 (mins)=2880 mins/month
hence Takt time will be 2880/400=7.2 Mins
But according SAP note627377 - Consulting Note : Model-Mix-Planning and Sequencing it says that"The duration of the takt time must always be less than the length of any shift of any line resource planned by MMP and Interactive Sequencing.".
Also in another similar note 769149 - Tact scheduling in the iPPE lines scenario it says that if you have defined base rate in resource in ippe The inverse of this number is the takt time: how long does it take to transport a product from the first takt to the second.
After going through above notes i am confused as how exactly this time is calculated in standard MMP.
Following is test data for a resource on ippe Line
L1_LAP(is defined as planning Segment)
Available capacity of the resource : 480 mins
Break: 20 mins
Base Rate: 410 Mins/EA
Takt defined in ippe line;1
L2_LAP
Available capacity of the resource : 480 mins
Break: 20 mins
Base Rate: 410 Mins/EA
Takt defined in ippe line;17
Above lines are defined as part of line network LN_LAP
Please let me know how we can calculate the takt time based on above data..
