Assignment #3: Julia’s Food Booth
A. Formulate and solve an L.P. model for this case:

X1 = pizza slices
X2 = hot dogs
X3 = B B Q sandwiches

This model is set up for the first home game.
Next, you would maximize Z = $0.75 x1 + 1.05 x2 + 1.35 x3 which is subject to the following:
$0.75x1 + 0.45x2 + 0.90x3 = 2.0 so x1, x2, x3 >=0
X3

All of which is displayed in the graph below. (Note: The oven space needed for a slice of pizza is determined by dividing the total space required by the slice of pizza, 14 x 14 = 196 in^2 by 8 or 24 in^2 per slice. The total space available would be the dimensions of the shelf, 36 in. x 48 in. = 1,728 in^2, multiply that by 2, the times before kickoff and halftime, thus the oven will be filled 55,296in^2.

Solution: X1 = 1,250 slices of pizza
X2 = 1,250 hot dogs
X3 = 0 bbq sandwiches
Z = $2,250

...Judge’s Score Sheet & Guidelines Chili will be judged according to 5 criteria. Chili will be rated on a scale of zero to 10 for each of the 5 categories; 1. Color – Chili should look appetizing, reddish brown is generally accepted as good. 2. Aroma – Chili should smell good. This also indicates what’s in store when you taste it. 3. Consistency – Chili must have a good ratio between sauce and meat. It should not be dry, watery, grainy, lumpy, or greasy. 4. Taste – Taste, above all else, taste is the most important factor. The taste should consist of a combination of meat, spices, etc. with no particular ingredient being dominant. 5. After-taste – The aftertaste or bite is the heat created by the various types of spices and or peppers. Judge each Chili on it’s on merit; do not compare one chili to another. Use a clean, new spoon for each chili Clear your palate between each chili. Use water or saltines. Place your score on the sheet blank that corresponds to the chili being judged. Do not talk to other judges or compare notes. If you have any food allergies, please ensure a Deja Brew employee is made aware of it before judging begins.

...Explanation: I conducted a random simulation with the information provided based on 52 base week calendar. Author B. Taylor stated “simulation can be applied to a number of problems that are too difficult to model and solve analytically” (Taylor, 2009). In this case the results were based on the use of one copy machine, intervals of breakdown, requiring 1-4 days for repair at a loss, at $0.10 cents a copy. Day 1: 20%, Day 2: 45%, Day 3: 25%, Day 4: 10% a total probability of 100%. The point of this case study is to simulate the break-down and repair process for one year to obtain an average annual loss of revenue. In addition the amount of time between breakdowns increases the probability of needing more costly repairs. Should the anticipated lost revenue exceeds $12,000.00 annually a backup copier will be purchased. We must keep in mind the most important factors of customer satisfaction and convenience, which is what, prompted the owners of JET to start their business in the first place. The first part of creating the probability of breakdowns relied upon information supplied by Jet Copies and their estimated probability of distribution. The nearby college staff had prior knowledge of the service provider’s timelines for repair because they had the same copier in the campus office. JET used their own estimated repair time to recreate a random repair time probability table using a range of days. As a result the average repair time was 3 days at a cost of $691...
