Assuming Kristen's Cookie Company is open for four hours each night, Kristen's Cookie Company can successfully complete 22 orders of a dozen cookies each. We know this because we know that one order takes 26 minutes, and every one after that takes 10 more minutes, so 16+10n = the amount of time to complete n orders. So for one order, 16+10(1) = 26 minutes. We know that in 4 hours, there are 240 minutes (4 x 60), so if we set 16+10n equal to 240, we get 22.4 orders, but because each order is sold in whole, we round down and know that we can make 22 orders of a dozen cookies each in 4 hours. 3.
1. How long will you take to fill a rush order? It will take 26 minutes, not including the preheat time, to fill a rush order. This is determined by first creating a process flow diagram (see Diagram 1); then adding the time each activity takes from start to finish for 1 dozen cookies (6+2+1+9+1+2+5= 26min). This is called the throughput time.
Since the capacity of the entire process is equal to the capacity of the bottleneck operation, we know that we can produce up to 6 dozen cookies in an hour. However, we also have a startup and cleanup time of 8 minutes each, this makes our effectively operational time to be less. Effective Operational Time=4 ×60minutes-16minutes=224minutes=3.73hours ------------------------------------------------- Max Orders filled in a night=3.73h×6dozenh=22.38 ≈22 dozens 3. Own time used to fill one order=6+2=8 minutes Roommate's
Case Report: Kristen’s Cookie Company Do Tra My – Section 24 1. Process Analysis: The flow chart is included in the Appendix Task | Order Entry | Wash+Mix | Spooning | Setting | Baking | Cooling | Packing | Accepting Payment | Total | Resource | None | You | You | Roommate + Oven | Oven | None | Roommate | Roommate | | Cycle Time (mins/dozen) | 0 | 6 | 2 | 1 | 9 | 5 | 2 | 1 | 26 | Capacity(dozens/hour) | Infinity | 10x3=30 | 30 | 60 | 6.67 | 12 | 30 | 60 | | Flow Time (mins) | | 6 | 2 | 1 | 9 | 5 | 2 | 1 | 26 | Table 1: Process Analysis Assumptions: * Order is for a full box (a dozen cookies), * The rush order takes priority before any other order The amount of time to fill a rush order is equal to the sum of the cycle time of all stages: 6+2+1+9+5+2+1 = 26 minutes 2. Assumptions: * Each person orders only one box (one dozen) and orders are constant and unlimited * The first order came in at the beginning of operation hours Total amount of operation hours in minutes: 4x60 = 240mins. The process analysis above showed us that the bottle neck of the process was the combination of two stages: setting and baking, which accounted for 10minutes in total. * Capacity of the bottle neck = capacity of the process = 60/10 = 6 dozens/hour.
Case Analysis: Kristen’s Cookies Company Preliminary Analysis: Inputs: Cookie Order Outputs: One dozen cookies Sequence of tasks: 1) 2) 3) 4) 5) 6) 7) Washing & Mixing Spooning Placing in Oven / Setting Timer Baking Cooling Packing Cookies in Boxes Processing Payment(s) The ability to produce a rush order, in a worker pace line, depends on whether or not we have cookies in inventory. If we don’t have any cookies in inventory then it would take 26 minutes to produce the first dozen and an additional 10 minutes per order to complete each additional dozen. 2) How long does it take to produce an order dozen cookies?

The shadow price or dual value is $1.50 for each additional dollar Julia would increase her profit, if she borrows some money. However, the upper limit of the sensitivity range is $1,658.88, so she should only borrow $158.77 and her additional profit would be $238.32 or a total profit of $2488.32. (C) Evaluate the prospect of paying a friend $100/game to assist. Yes, she should hire her friend for $100/game for it is almost impossible for her to prepare all the food in such a short time. In order for Julia to prepare the hotdogs and barbeque sandwiches she would need the additional help.
The company has 60 hours available each week for molding. After the tiles are molded they are baked in a kiln: 0.27 hour for a batch of 100 larger tiles and 0.58 hour for a batch of l00 smaller tiles. The company has 105 hours available each week for baking. After baking, the tiles are either colored or patterned and glazed. This process takes 0.16 hour for a batch of 100 larger tiles and 0.20 hour for a batch of 100 smaller tiles.
