Case Report : Kristen’s Cookie Company (A1)

Key Questions
1. To know the time it will take us to fill a rush order, we have to know how many dozens the rush order requires. If it is only one dozen, we need 6 minutes for the washing and mixing steps, 2 minutes for the spooning, 10 minutes for the whole baking, 5 minutes to cooling down, 2 minutes for the packing and 1 minute for the payment. That is to say : 26 minutes. If we consider the order requires N dozens : we always need the first 8 minutes to do the washing and mixing steps and the spooning. As long as the oven can only contain 1 dozen, we need 10xN minutes for the baking of all of the N dozens. I can use the time my roomate needs to bake 1 dozen to produce new cookies (washing + mixing + spooning) if the next dozen order requires a different flavour or if I already made 3 dozens. Finally, my roomate can use the 9 minutes of each baking (except the first one) to do the cooling packing and payment of the previous dozen order. That is why, the time needed to fill a rush order of N dozens is : 8 + 10xN + 5 + 2 + 1 = 16 + 10xN minutes. 2. We assume we are open 4 hours each night. Using Question 1, we know we need 16 + 10xN minutes to fill a N dozens rush order. We want to maximize N knowing we have to have 16 + 10xN < 240. We easily find N = 22. We can fill 22 orders in a night. 3. For me : I only wash the mixer, mix ingredients and spoon the cookies that is why my valuable time for one order is 8 minutes. For my roomate : he sets the oven, remove cookies from it at the end of the baking, pack them and accept the payment that is why his valuable time for one order is : 1 + 0 + 2 + 1 = 4 minutes. 4. We know the costs of boxes and ingredients do not change so the only thing which can change is the cost of time. For 1 dozen, question 3 tells us we have a total valuable time of 12 minutes. For 2 dozens, we will have a total valuable time of 6 + 2 x (2 + 1 + 2) + 1= 17 minutes....
...will produce and sell cookies by the dozen. Should you give any
discount for people who order two dozen cookies, three dozen
cookies, or more? If so, how much? Will it take any longer to fill a two
dozen cookie order than a onedozen cookie order?
You can only give a discount if the cost of your raw materials decrease because of your
ability to get a discount from a supplier for purchasing larger quantities, or...
...+ activity time at the bottleneck = 26 + 10 = 36 minutes. Similarly, theoretical flow time of 3 dozen = theoretical flow time of the first dozen + 2 * activity time at the bottleneck = 26 + 2*10 = 46 minutes.
