Modelling and Simulatoin

a. Resimulate 15 days of barge unloading and compute the average number of barges delayed, average number of barges delayed, average number of nightly arrivals, and average number of barges unloaded each day. Draw random numbers from the bottom row of Table 15.5 to generate daily arrivals and from the second-from-the-bottom row to generate daily unloading rates. b. How do these simulated results compare with those in this chapter? See attached file for full problem description.

Modelling and Simulation

Clark Property Management is responsible for maintenance, rental, and day-to-day operation of a large apartment complex on the east side of New Orleans. George Clark is especially concerned about the cost projections for replacing air conditioner compressors. He would like to simulate the number of compressor failures each year over the next 20 years. Using data from a similar apartment building he manages in a New Orleans suburb, Clark establishes a table of relative frequency of failures during a year. See attached file for full problem description.

1. What symbol is used to represent the mean of the sampling distribution of y-(ybar)? Explain 2. What symbol is used to represent one value from the sampling distribution of y-(ybar)? Explain

How many units should be shipped from each plant to each region distribution center? What is the total cost for this?

Note: Please review the PowerPoint Slides using the link below for the next two problems: http://wps.prenhall.com/bp_render_qam_9/0,11119,2557508-,00.html An air conditioning manufacturer produces room air conditioners at plants in Houston, Phoenix, and Memphis. These are sent to region distributors in Dallas, Atlanta, and Denver. The shipping costs vary, and the company would like to find the least-cost way to meet the demands at each of the distribution centers. Dallas needs to receive 800 air conditioners per month, Atlanta needs 600, and Denver needs 200. Houston has 850 air conditioners available each month, Phoenix has 650, and Memphis has 300. This shipping cost per unit fro... click for more

Lagrange multiplier / linear algebra equivalances

Please see attached PDF file; I'm trying to derive a couple of results involving Lagrange multipliers and a linear algebra equivalence. This makes use of the extension to Lagrange multipliers whereby the constraint is an inequality (see, e.g., section 5.1 of http://www.cs.berkeley.edu/~klein/papers/lagrange-multipliers.pdf ).
