Morning Teacher,
Have a question about Sweet Treats Bakery December 2016 exercise. How to calculate the bottleneck on this exercise. because they says (The product must be produced in their batch sizes). and they have Minimum and Maximum daily demand in units.
For exemple ‘ Batch size units to produce Brownies is 40. Min (30 UN) and Max(140) daily demand. The process is Weighing 15minutes, Mixing 20minutes and Baking 120minutes.
To meet maximum demand, the need to produce 4 batches of brownies, 3 batches of muffins, and 5 batches of cupcakes. (It is 4 batches of brownies because the have to produce in batches of 40 and so for 140 they need 4 batches).
The total time needed to produce maximum demand is as follows:
Weighing: (4 x 15) + (3 x 15) + (5 x 20) = 205 minutes
Mixing: (4 x 20) + (3 x 16) + (5 x 12) = 188 minutes
Baking: (4 x 120) + (3 x 110) + (5 x 120) = 1410 minutesThe time available (per the question) is:
Weighing: 240 minutes
Mixing: 180 minutes
Baking: 1440 minutesSo it is only mixing where the time available is not enough, and so mixing is the bottleneck process.
