Determine the EOQ for a company with annual demand of 20,000 units, ordering cost of $75 per order, and carrying cost of $4 per unit per year. Calculate the total number of orders per year and the total inventory cost. Discuss how EOQ optimizes inventory management by balancing ordering and carrying costs. Analyze the impact of changes in demand, ordering cost, and carrying cost on the EOQ. Consider the implications of ordering more or less than the EOQ on the company's inventory levels and cost structure. Discuss the strategic benefits of using EOQ for inventory planning, including improved cash flow management and reduced stockouts. Explain how EOQ can be integrated with other inventory management techniques, such as just-in-time (JIT) and safety stock, to enhance overall supply chain efficiency.
