Kabel Market store sells electric cable. The demand for cable is normally distributed. The inventory related information at Kabel Market is as follows: Average Annual Demand = 16,900 meters Standard deviation of weekly demand = 28 meters Cable selling price = AMD 640.00 per meter Ordering cost = AMD 1,250.00 per order Lead time = 5 weeks Annual inventory-holding cost estimate = 2.5% of the cable selling price Required service level = 95% Kabel Market works 52 weeks a year. Note: The approximate z values are: for 0.9 ≈ 1.28, for 0.92 ≈ 1.405, for 0.95 ≈ 1.645, for 0.98 ≈ 2.05. Suppose the bar management practices the fixed-QUANTITY ordering system with the use of the economic order quantity. Answer the following questions: (i) How many meters of cable they order from the supplier each time? (ii) When do they place an order? (iii) What is the safety stock?
