QUESTION 19 Given the data: K = 5100, h = $1, r= (20, 30, 50, 10, 20, 30). Determine the optimal order policy and the cost (including set-up and holding costs) using the following heuristic lot-sizing scheme. What is the optimal order policy based on least unit cost heuristic? Select the closest answer: O a.r = (100, 0, 0, 60, 0, 0) O b.r = (50, 0, 80, 0, 30, 0) Oc.r = (50, 0, 80,30, 0, 0) O d.r = (50, 0, 80, 0, 0, 30) Consider the same data in Question 19. What is the optimal cost (including set-up and holding costs) based on least unit cost heuristic? Select the closest answer: a. 340 b. 360 c. 380 d. 400
