Summary Introduction
Case summary:
The case deals about the call center of State A’s airlines, which has 800 reservation systems. The information related to the phone calls between midnight and 6:00 A.M. is as follows:
| Time between calls (minutes) | Probability | Cumulative probability | Random number interval |
| 1 | 0.11 | 0.11 | 01-11 |
| 2 | 0.21 | 0.32 | 12-32 |
| 3 | 0.22 | 0.54 | 33-54 |
| 4 | 0.2 | 0.74 | 55-74 |
| 5 | 0.16 | 0.9 | 75-90 |
| 6 | 0.1 | 1 | 91-00 |
| Time to process customer inquiries | Probability | Cumulative probability | Random number interval |
| 1 | 0.2 | 0.2 | 01-20 |
| 2 | 0.19 | 0.39 | 21-39 |
| 3 | 0.18 | 0.57 | 40-57 |
| 4 | 0.17 | 0.74 | 58-74 |
| 5 | 0.13 | 0.87 | 75-87 |
| 6 | 0.1 | 0.97 | 88-97 |
| 7 | 0.03 | 1 | 98-00 |
Customers of the airline does not want to be in hold for more than 3 to 4 minutes. As a part of new television advertising campaigns, the incoming call distribution from midnight to 6:00 A.M. is as follows:
| Time between calls (minutes) | Probability | Cumulative probability | Random number interval |
| 1 | 0.22 | 0.22 | 01-22 |
| 2 | 0.25 | 0.47 | 23-47 |
| 3 | 0.19 | 0.66 | 48-66 |
| 4 | 0.15 | 0.81 | 67-81 |
| 5 | 0.12 | 0.93 | 82-93 |

Question 1:
Assume that you own and operate a business. Your production this year was based on prior
years' experience. You have been left, however, with 100,000 unsold units on hand. You have
been selling your product at $5 each and expected the same price for these 100,000 units. You
have exhausted all avenues you can think of for disposing of your excess product. You do not
have the storage capacity for keeping these units in inventory while you continue production.
This morning a giant retail organization contacted you urgently seeking the type of product you
produce to fill deficits in their supply. They offer to pay you $3 per unit.
1. How would you assess whether or not you should negotiate? Identify the factors you
would consider and give reason for their consideration.
[YOU MUST GIVE THE REASON FOR CONSIDERATION OF EACH FACTOR
SEPARATELY OTHERWISE YOUR ANSWER WILL NOT BE ACCEPTABLE]
2. What factors can you readily identify that will affect your negotiation options and…
Problem 7-09 (Algorithmic)
Hawkins Manufacturing Company produces connecting rods for 4- and 6-cylinder automobile engines using the same production line. The cost required to set up the production line to produce the 4-cylinder connecting rods is $1,400, and the cost required to set up the production line for
the 6-cylinder connecting rods is $3,100. Manufacturing costs are $15 for each 4-cylinder connecting rod and $18 for each 6-cylinder connecting rod. Hawkins makes a decision at the end of each week as to which product will be manufactured the following week. If a production
changeover is necessary from one week to the next, the weekend is used to reconfigure the production line. Once the line has been set up, the weekly production capacities are 6,500 6-cylinder connecting rods and 8,200 4-cylinder connecting rods.
Let
X4 = the number of 4-cylinder connecting rods produced next week
X6 = the number of 6-cylinder connecting rods produced next week

The students kept track of many lifestyle variables including how many hours of sleep obtained on a typical day. Researchers found that visually impaired students averaged 9.2 hours of sleep, with a standard deviation of 2.24 hours. Assume that the number of hours of sleep for these visually impaired students is normally distributed. (a) What is the probability that a visually impaired student gets less than 6.4 hours of sleep? answer: (b) What is the probability that a visually impaired student gets between 6.2 and 8.84 hours of sleep? answer: (c) Thirty percent of students get less than how many hours of sleep on a typical day? answer: hours Note: You can earn partial credit on this problem.

- Question 1The Rotary Club is holding a pizza sale to finance outreach projects. The Club made an agreement to purchase pizza from Pizza Hut at a 30% discount which the Rotary Club can then resell for a profit. It is expected that of the 500 families in the community, at most 70% will buy pizza. Based on a survey of their personal preferences, the students believe that they should orderno more than 120 cheese pizzas, no more than 150 pepperoni pizzas, and no more than 100 vegetarian pizzas. They also want to make sure that at least 20% of the total pizzas are cheese and at least 50% of the pizzas are pepperoni. The standard price (before discount) for the cheese, pepperoni and vegetarian is $12, $15 and $14, respectively. The Rotary Club makes a profit of 10%, 15% and 20%, respectively, for each cheese, pepperoni, and vegetarian pizza they resell. a) Formulate a linear programming model that would determine the optimal solution.
