DSME2030A ASSIGNMENT 1 (b) for orders of two dozens __________ minutes Assuming the work arrangement has not been adjusted, a Gant Chart (Basic case 2) for two dozens orders is developed as follow.
Therefore, it takes 36 minutes to finish a two dozens rush order. 2. For orders of one dozen, how many orders can you fill in a night? Assuming 4 hours
per night Answer: We can find from basic case 1 that we will spend 10 more minutes with one more dozen ordered, because the oven has already been fully utilized and become bottleneck under this circumstance. We know that the roommate can prepare oven for baking the second dozen just after finishing baking the first dozen, during the 10 minutes when the oven is prepared and the second dozen is baking, the first dozen can be cooled and packed in 7 minutes, and the remaining 3 minutes are enough for collecting money, moreover washing, mixing and spoon for the second dozen can be finished during the time of first baking. So we have proved that we need 10 more minutes when one more order are required. We can construct a formula to express relationship between time (T, in minutes) and number of dozen(X) T=16+10X Assuming 4 hours(240 minutes) per night, here is the formula 240 16 10 x x 22 So we can make 22 dozen of cookies and also 22 orders per night.
