Kristen’s Cookie Case ReportTeam Name: Les InconnusAuthorsAllali FarahBeguin LauraMernier HélèneVan Bael JonathanFebruary 2016 As shown below the flow-time of the process is 26 minutes. (1 point)[pic 1]As said in the first question, they need 26 minutes for the first dozen. The cause behind this time is the fact that they have to go through the whole process. To find how many orders they can fill in 240 minutes, we need to find the bottleneck which is the oven? The cycle time of the oven is 10 minutes, mixing and dishing takes 8 minutes. This means that we can make the first and 10 minutes later the second. We can find our answer in the following equation: 240= 26+10*(X-1), the answer of this equation is x=22,4. This means that they can finish 22 orders in 4 hours. ( 1 point)The work she does is mixing the ingredients and dishing them up on a tray, which takes 8 minutes. Her roommate puts them in the oven (1’), does the packing (2’) and the payment (1’). Her work represents thus 4 minutes of her time.  The both of them work 12 minutes on the cookies. This calculation is only for completing one order of a dozen cookies.  (1 point)One way to find the answer at this question is to analyze the valuable time. 1 dozen (/minutes)2 dozen(/minutes)3 dozen(/minutes)washing and mixing666put on the tray22+2=42+2+2=6Set the oven11+1=21+1+1=2Baking99+9=189+9+9=27Cooling down55+5=105+5+5=15The packing22+2=42+2+2=6The payment111Total of time of human work121722We can imagine the human work cost 10 euros an hour, which means that the cost per minute is 0.1667 euros.

If we cook 1 dozen of cookies they’ll need 12 minutes of human work. We can see that if they cook two batches of cookies that they’ll need 17 minutes, which means 8.5 minutes for a dozen. If they cook three batches they’ll need 22 minutes, which means 7.3 minutes for a batch.
