Question 1
PKG Electric makes two types of electric fans, ceiling fan and wall fans. Each ceiling fan requires two circuit boards and four hours assembly time. Each wall fan requires two circuit boards and one-hour assembly time. The profit of each ceiling fan and wall fan are RM25 and RM15 respectively. The company produces its own circuit boards and its capacity is 54 per week. Currently, the company has 48 hours of assembly time per week. The company wishes to maximize the profit.
Let x = ceiling fan, y = wall fan
Solve:
1. Formulate the problem as a linear programming model.
2. What is the maximum profit?
3. Later, the company was informed by its retailers that the demand for the wall fans is at most 12 units per week. What is the new maximum profit?

- question 7 You manage an ice cream factory that makes two flavors: Creamy Vanilla and Continental Mocha. Into each quart of Creamy Vanilla go 2 eggs and 3 cups of cream. Into each quart of Continental Mocha go 1 egg and 3 cups of cream. You have in stock 450 eggs and 750 cups of cream. You make a profit of $3 on each quart of Creamy Vanilla and $2 on each quart of Continental Mocha. How many quarts of each flavor should you make to earn the largest profit?

Each driver obtains a benefit v from the journey and incurs a cost c(N ) that increases with the number of drivers on the road due to congestion. Suppose that the cost incurred is given by c(N) = a+bN, for some positive numbers a, b. If the agent decides not to use the road, they receive 0. You may assume throughout that the number of drivers N can be any real number (rather than an integer). Each driver uses the road at most once. the number of drivers that join the road is Ne = (v−a)/b (iv) Suppose that the government charges a toll t (a congestion charge) for each journey. Find the optimum toll. Interpret your answer in terms of the externality that each driver imposes on others.arrow_forwardQuestion 4Consider a birth death model with birth rates in states n = 0, 1, . . . and death rates in states n = 1, 2, . .

- Question #4 - Jerry Smith is thinking about opening a bicycle shop in his hometown. Jerry loves to take his own bike on 50-mile trips with his friends, but he believes that any small business should be started only if there is a good chance of making a profit. Jerry can open a small shop, a large shop, or no shop at all. The profits will depend on the size of the shop and whether the market is favorable or unfavorable for his products. Because there will be a 5-year lease on the building that Jerry is thinking about using, he wants to make sure that he makes the correct decision. Jerry is also thinking about hiring his old marketing professor to conduct a marketing research study. If the study is conducted, the study could be favorable (i.e., predicting a favorable market) or unfavorable (i.e., predicting an unfavorable market). Develop a decision tree for Jerry.arrow_forwardQuestion Suppose there are only two goods: Beer and Milk. Tom’s preference over bundles of beer and milk is as follows: For any two bundles A = (bA, mA) and B = (bB, mB) (where b and m denotes the amount of beer and milk, respectively), A ≿ B (i.e., “A is at least as good as B”) if and only if: Either bA > bB; Or bA = bB and mA ≥ mB. In other words, Tom cares, first and foremost, about the amount of beer, but if the two bundles contain the same amount of beer, then he prefers having more milk to less. • Is Tom’s preference complete? If yes, show why; if no, give an example of two bundles which Tom cannot compare. • Is Tom’s preference monotone? Strongly monotone? • Does Tom’s preference comply with the property of diminishing marginal rate of substitution?arrow_forwardQuestion 1. Busch Gardens Sweets is preparing for the Halloween rush. They prepare two sizes of Peanut/Raisin Ghoulish Delight and need to calculate how many bags of deluxe and standard mixes they can produce. • The deluxe mix takes 0.9 of a pound of raisins and 0.4 of a pound of peanuts.• The standard mix takes 0.7 of a pound of raisins and 0.6 of a pound of peanuts.The shop has 100 pounds of raisins and 70 pounds of peanuts. The profit on the deluxe mix is $1.80 and the standard mix profit is $1.60. The owner wants no more than 110 bags of each type prepared.

The profits per unit are $6 and $4 respectively. Each corrugated box requires 2 minutes for cutting and each carton requires 3 minutesfor cutting, whereas each corrugated box requires 2 minutes for pinning and each carton requires 1 minute for pinning. The available cutting time is 120 minutes and total pinning time is 60 minutes. Determine the optimum quantities of the two boxes to maximize the profits. a. Formulate a linear programming model that can be used to determine the quantities of the two boxes that should be produced in order to maximize total profit contribution b.

As the suppliers all reside in a location prone to hurricanes, tornadoes, flooding, and earthquakes, Phillip believes that the probability in any year of a "super-event" that might shut down all suppliers at the same time at least 2 weeks is 3%. Such a total shutdown would cost the company approximately $480,000. He estimates the "unique-event" risk for any of the suppliers to be 5%. Assuming that the marginal cost of managing an additional supplier is $14,800 per year, how many suppliers should Witt Input Devices use? Assume that up to three nearly identical local suppliers are available. Part 2 Find the EMV for alternatives using 1, 2, or 3 suppliers.

Question 6 options: 1) Climate involves statistics (e.g., long-term averages) but weather considers conditions at a particular time and place (e.g., one week of this summer). 2) The current weather at a location can be characterized by a single measurement, but climate requires many years of measurements (typically around 30) to characterize. 3) Both weather and climate can vary regionally (e.g., from one side of a mountain range to another). 4) Climate only refers to temperatures, but weather also includes other factors like wind, rain, and snow.arrow_forward
