Question description

I have about 4 or 5 open assignments on, one including a separate excel sheet which I will attach here. If you accept the bid I'll message you my account information and we could go from there. Each assignment is about 2 or 3 questions.

Reliability Homework 1. Suppose the cumulative distribution function of the lifetime of a piece of operating equipment is given by -.6t -,6t F(t) = 1 – e - .6te where t is measured in years of continuous operation. a. Determine the reliability function b. Determine the failure rate function c. What is the probability that this piece of equipment fails in the first year of operation? d. What is the probability that it fails in the fifth year of operation? e. What proportion of the equipment surviving four years fails in the fifth year? 2. An engine fails with probability p. Assume that for a machine using these engines to work at least half the engines have to be operating. Analyze a two-engine machine versus a four-engine machine for failure probabilities of .167, .33, .5, .66, and .833. AHP Homework Starting with the Excel spreadsheet to calculate the weights of a 4x4 matrix, change it so that it becomes a 3x3 matrix and augment it with formulas needed to calculate the Consistency Index. Insert the values from slide #9 to verify the answers on slide #12 in Lecture 13 Part 4. Calculate the consistency index for the problem. Attach the spreadsheet as your final solution.
