Industrial Engineering 335 Spring 2012 Operations Research-Optimization Lecturer: Nelson Uhan Grader: Jikai Zou January 25, 2012 Quiz - 20120125 Solutions Problem: Recall Homework 2, Problem 8: Suppose that an optimization model with decision variables w 1 and w 2 has constraints - 2 w 1 + w 2 5 w 1 0 . Give a minimizing linear objective function for which the model has multiple optimal solutions. w 1 w 2 Solution: See Homework 2 Solutions, Problem 8. In addition,

Unformatted text preview: minimize 2 w 1-w 2 could be another solution to this problem. Note : an objective function is NOT an equality (e.g. 2 w 1-w 2 = 5), or an inequality (e.g. w 1 ≥ 0). It consists of two parts: the direction you are going to optimize, i.e. minimize or maximize, and an expression you are optimizing, (e.g. 2 w 1-w 2 , or w 1 ). 1...
