Non-linear programming (NLP):

Non-linear programming (NLP) is used in complex optimization problems where the objectives or constraints or sometimes both are non-linear functions of the decision variables. A model can be termed as non-linear for more than one reason.

The central limit theorem implies which of the following:   a. The averages of many random samples (of a given sample size n) from the same population are approximately normally distributed, but only if the population is normally distributed.     b. The averages of many random samples (of a given sample size n) from the same population are approximately normally distributed with mean μ and standard deviation σ / √n , but only if the population is normally distributed.     c. The averages of many random samples (of a given sample size n) from the same population are approximately normally distributed, regardless of the shape of the population distribution, provided that n is sufficiently large.     d. None of these choices are true.

  • You want to take out a 450,000 loan on a 20-year mortgage with end-of-month payments. The annual rate of interest is 3%. Twenty years from now, you will need to make a 50,000 ending balloon payment. Because you expect your income to increase, you want to structure the loan so at the beginning of each year, your monthly payments increase by 2%. a. Determine the amount of each years monthly payment. You should use a lookup table to look up each years monthly payment and to look up the year based on the month (e.g., month 13 is year 2, etc.). b. Suppose payment each month is to be the same, and there is no balloon payment. Show that the monthly payment you can calculate from your spreadsheet matches the value given by the Excel PMT function PMT(0.03/12,240, 450000,0,0).
    Suppose that GLC earns a 2000 profit each time a person buys a car. We want to determine how the expected profit earned from a customer depends on the quality of GLCs cars. We assume a typical customer will purchase 10 cars during her lifetime. She will purchase a car now (year 1) and then purchase a car every five yearsduring year 6, year 11, and so on. For simplicity, we assume that Hundo is GLCs only competitor. We also assume that if the consumer is satisfied with the car she purchases, she will buy her next car from the same company, but if she is not satisfied, she will buy her next car from the other company. Hundo produces cars that satisfy 80% of its customers. Currently, GLC produces cars that also satisfy 80% of its customers. Consider a customer whose first car is a GLC car. If profits are discounted at 10% annually, use simulation to estimate the value of this customer to GLC. Also estimate the value of a customer to GLC if it can raise its customer satisfaction rating to 85%, to 90%, or to 95%. You can interpret the satisfaction value as the probability that a customer will not switch companies.

    A study on ethics in the workplace by the Ethics Resource Center and Kronos, Inc., revealed that 35% of employees admit to keeping quiet when they see coworker misconduct. Suppose 70% of employees who admit to keeping quiet when they see coworker misconduct call in sick when they are well. In addition, suppose that 45% of the employees who call in sick when they are well admit to keeping quiet when they see coworker misconduct. If an employee is randomly selected, determine the following probabilities:a. The employee calls in sick when well and admits to keeping quiet when seeing coworker misconduct.b. The employee admits to keeping quiet when seeing coworker misconduct or calls in sick when well.c. Given that the employee calls in sick when well, he or she does not keep quiet when seeing coworker misconduct.d. The employee neither keeps quiet when seeing coworker misconduct nor calls in sick when well.e. The employee admits to keeping quiet when seeing coworker misconduct and does not…
  • I need help with everything, please. Formulate the problem and submit formulation - no need to solve. 1. An investment advisor at Shore Financial Services wants to develop a model that can be used to allocate investment funds among four alternatives: stocks, bonds, mutual funds, and cash. For the coming investment period, the company developed estimates of the annual rate of return and the associated risk for each alternative. Risk is measured using an index between 0 and 1, with higher risk values denoting more volatility and thus more uncertainty. Because cash is held in a money market fund, the annual return is lower, but it carries essentially no risk. The objective is to determine the portion of funds allocated to each investment alternative in order to maximize the total annual return for the portfolio subject to the risk level the client is willing to tolerate. Total risk is the sum of the risk for all investment alternatives. For instance, if 40% of a client’s funds are…
