Fajar Corp., plans to order 4,732 units of inventory each time, every 4 weeks for the coming year. Assume 52 weeks a year. The firm wants to maintain a safety stock of 3,000 units of inventory. The firm's estimated inventory ordering cost is RM273 per order, whereas inventory carrying cost is RM6 per unit per year. You, a fresh UUM graduate, have just joined Fajar Bhd., and have been tasked to improve its inventory management.
