((240) – 26) / 10) + 1 = 22.4 Note* 22 orders per night is based on the maximum order of 3 dozen because of the amount the bowl can handle for each process flow. It also assumes that all the cookies are the same, for example they are all chocolate chip cookies for the batch of 3 dozen. 3. How much of your own and your roommate's valuable time will it take to fill each order? In Diagram 1, it shows that You would take a total of 8 minutes (6+2=8min) for the following items: • Wash Items & Mix Ingredients • Spoon on Cookies Sheet The diagram also shows the total time of 4 minutes (1+1+2= 4min) of time will be used of the RM, for the following times: • Load & Set Cook Time • Accept Payment • Pack Order Note* the Oven time will not take either person’s time except for idle time.
1. It will take Kristen's Cookie Company 26 minutes to fill a rush order of one dozen because washing the bowl and beaters, adding the ingredients and mixing the ingredients takes 6 minutes; spooning the cookies takes 2 minutes per dozen; putting the cookies in the oven takes 1 minute; cooking time is 9 minutes; letting them cool takes 5 minutes; it takes 2 minutes to pack each box; and it takes 1 minute to accept payment. All of these processes add up to 26 minutes. 2. 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.

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?

Case Report: Kristen’s Cookie Company (A1) Wash & Mix 6m Spooning 2m Heating 1m Baking 9m Pack & Pay 3m Cooling 5m Wash & Mix 6m Spooning 2m Heating 1m Baking 9m Pack & Pay 3m Cooling 5m Figure 1 - Process flow chart of Kristen's Cookie Company 1. The question is asking for the flow time of the process, which is the time taken for a unit (a dozen cookies) to be completed. Based on Figure 1, we can easily determine this. The total time required to fill in a rush order includes washing and mixing (6m), spooning (2m), heating (1m), baking (9m), cooling (5m), and packing (3m), which totals up to 26 minutes. ------------------------------------------------- Flow time=Time required for all processes=F6+2+5+9+1+3=26 minutes 2.

What percentage of the kernels will fail to pop if the popcorn is cooked for (a) 2 minutes? (b) Three minutes? (c) If you wanted 95 percent of the kernels to pop, what time would you allow?
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.
Folks were waiting in line for almost an hour to get their doughnuts. When that store opened Sherriff’s deputies had to be brought to control traffic jams for almost a week after its grand opening. Furthermore, according to a local newspaper report, on one particular night, Krispy Kreme had 150 cars waiting to get their doughnuts in the drive through lane. To exploit the thrilled and excited customers that like hot and fresh doughnuts, Krispy Kreme opened additional stores at record pace throughout 2002-2003. Krispy Kreame’s key business strategy and model were designed to add plenty of new stores and to increase sales at existing stores to achieve 20 percent annual revenue growth and 25 percent annual growth in earnings per share.
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.
One day is required for the cleaning process.

It worked. Here's how it went down. Preparing I sit down with Dr. Will Clower, whose new book, Eat Chocolate, Lose Weight, set off this harebrained scheme. ECLW is almost 300 pages, but the kicker is this: You can eat whatever you want during meals, but you forego other snacks and sweets in favor of starting and ending each meal with a small piece of very dark chocolate. Every meal-yes, including breakfast-needs a "starter" and an "ender" of dark chocolate, specifically the high cocoa content kind (70% cocoa or above).
