Operation Research

(Optional) Question 3 (Extra 10 points if grade not at maximum) Determine if the following statements about Operations Research (OR) and Linear Programming (LP) are True or False. a) An OR team should solely be formed by engineers. b) In real life, I can expect that management objective will be clear, the mathematical formulation will be given and all relevant data are readily available. c) Good communication with management increases the chances of a successful study and implementation. d) When gathering data, it is not a problem to have very few data available. e) Constraints are important to represent real life limitation in a LP problem. f) You can completely rely on an optimal solution and seek to implement it straight away. g) Simplex through geometric approach and tabular approach will lead to different solutions. h) Post-optimality should always be an optional step of a LP study. i) If a slack variable is higher than zero, the shadow price of the constraint is always higher than zero. j) If the shadow price of a resource is 10 , the average market price of this resource is 10
