Problem 3-24 (Algo)Zeus Computer Chips, Incorporated, used to have major contracts to produce the Centrino-type chips. The market has been decliningduring the past three years because of the quad-core chips, which it cannot produce, so Zeus has the unpleasant task of forecastingnext year. The task is unpleasant because the firm has not been able to find replacement chips for its product lines.

The problem is based on the following data given. Observations of the demand for a certain part stocked at a parts supply depot during the calendar year 2013 were ( as shown ). What would an MA(1) forecasting method mean? Compare the accuracy of MA(1) and MA(4) forecasts for July through December 2013.
6-58. A pump for a reservoir must be operated continuously (8,760 hours per year). In the event of a large storm, the electricity from the local utilitv's power grid may be interrupted for an indefinite period of time. To deal with this emergency situation, two mutually exclusive backup diesel generators are being investigated. One of them will be chosen for implementation. Relevant data are provided as follows: Generator A Generator B Initial investment $100,000 Annual operating $130,000 8,000 088 20AM and maint. 9,500 Useful life, years o 15 If salvage values of both generators are negligible and the study period is 60 years, which generator should be chosen?

A golfer practices different parts of their game for hours. Specifically, the golfer practices:(1) putting, (2) their short game, and (3) their iron game. The amount of time spent on each partof their game is exponentially distributed. If the golfer is practicing their putting, they will alwaysswitch to their short game after an average of 30 minutes. When the golfer practices their short game,they do so for an average of 45 minutes, and then switches to putting with probability 0.6 or to theiriron game with probability 0.4. When they practice their iron game, they do so for an average of 60minutes. After practicing their iron game, the golfer will switch to putting or to their short game withequal probability.(a) Draw the CTMC rate diagram, clearly label your states and transition rates (qij ’s)(b) Find the transition rates out of the states (vi’s) and transition probabilities (Pij ’s).(c) Find the limiting probabilities (make sure to write out the balance equations).(d) In the long…

Return to Test Question 16, Step 1 of 1 loved Solution 2 caldian Dana 1 of 1 1 Hawkes Learning | Portal Correct Answer: $56,954.45 Tutor-Solution Page 1 of 1 | Hawkes Learning | Portal The balance owed on your credit card triples from $800 to $2400 in 9 months. If the balance is grow linearly then it would take 34.9 months to reach $7000. If, on the other hand, the balance is growing 800(1+0.13)* where x represents the number of months, what would the b be after 34.9 months? Round your answer to the nearest cent. exponentially, f(x) 31550 f(x) = In order to solve this problem, we assume the balance is growing according to the exponential functi 800(1 + 0.13)*, where the variable x represents the total number of months. Here we are interested in knowing what the balance would be after 34.9 months, so substitute 34.9 for x. 315496 f(x) = 800(1.13)* f(34.9) = 800(1.13) 34.2 ≈ 56,954.45 So the balance after 34.9 months would be $56,954.45. Notice that your answer is greater than $70 Over a…

Question 6 Having studied Fixed Income Securities, you are now working as an analyst for a well known bond fund. Your manager asks you to replicate the JP Morgan T-Bond Index using a tracking error minimization approach. You are to replicate this index as closely as possible using a medium duration Treasury bond (M-BOND) and a long duration Treasury bond (L-BOND). These expire in approximately 7.15 years’ and 29.25 years’ time respectively. The following variance-covariance matrix, based on daily returns over the preceding six months, is given to you to use in your replication: Note: As usual, variances are given on the diagonal, e.g. the variance of M-BOND is 0.0042%. As usual, covariances appear in the non-diagonal elements, e.g. the covariance of M-BOND and L-BOND is 0.0057%. (a) Suppose the optimal weights for M-BOND and L-BOND are 0.7 and 0.3. Calculate the expected tracking error of the portfolio and explain how you interpret this number. (b) Calculate the correlation matrix…
Tonys Restaurant is a company that manufactures two types of cooking pans. The forecasted amount of demand for next year for each pan as well as the production requirements are given below. Tony likes to maintain a capacity cushion of 20.6 %. Pan 1 Pan 2 Forecast of demand (qty) 55370 38000 Processing time (hours) 0.1 0.08 Average lot (batch) size 100 100 Setup time (hours) 2 1.5 The pans are produced on a large press machine. A press machine can be configured (setup) to produce either of the two pans. Assume her factory works for 250 days in a year, and there is only one 8-hr shift per working day. How many machines does Aunt Karen need to fulfill demand next year (enter your answer rounded to 2 decimal places)?
