1 Homework 4 15.053 Introduction to Optimization Due at the beginning of class Thursday, March 7, 2002 1. BHM: Exercise 2, page 125. http://web.mit.edu/jorlin/www/spreadsheets/P125_Ex_2.xls Note that the RHS coefficient for the camera constraint should be 90 rather than 60. Answer the questions a to d using the sensitivity report from Excel given on the spreadsheet at the URL above. You may also solve the LP multiple times in order to verify your answers, but all justifications should be based on the sensitivity report. For part d, notice that the shadow price for overtime typesetting is less than the shadow price for regular typesetting. In order to see why the prices are what they are, solve the problem with an additional unit of regular typesetting and see how the optimal solution changes. Then do the same for overtime typesetting. For part c, take a close look at the sensitivity report for the row CO. There are two different clues that there are multiple optima in that row. You can verify that there are multiple
