Question

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.

A hurricane has been predicted to make landfall in Louisiana. The counties that lie within the path of the storm along with current population estimates are given in Table 1 below. There are several regional warehouses located in Texas, Alabama and Georgia that have capacity available to lease so that supplies can be prepositioned in advance of the storm. The lease capacity available at each of the warehouses is 100,000 units of MREs (meals ready-to-eat). The cost to lease each warehouse along with the capacity available is displayed in Table 2. The distance (in miles) to ship product to each of the counties from each possible warehouse location is summarized in Table 3. Assume travel cost is proportional to distance traveled. Formulate a mathematical model that will determine which of the warehouses to use to preposition MREs and the amount shipped from each warehouse to each of the counties to assist those who are in need after the storm. Assume that 25% of the population will…

The supervisor at the Precision Machine Shop wants to determine the staffing policy that minimizes total operating costs. The average arrival rate at the tool crib, where tools are dispensed to the workers, is eight machinists per hour. Each machinist’s pay is $25 per hour. The supervisor can staff the crib either with a junior attendant who is paid $13 per hour and can process 12 arrivals per hour or with a senior attendant who is paid $16 per hour and can process 16 arrivals per hour. Which attendant should be selected, and what would be the total estimated hourly cost?

A solar power field is located on the south bank of a straight river that is 2 km wide. A power line is to be constructed from the solar field to an electric substation located on the north bank of the river 4 km east of the solar field. The cost of running the power line is $100,000/km overland and $200,000/km under the river. To minimize the cost of the power line, how much of the power line should be run overland?
