A company has an annual demand of 25,000 units, an ordering cost of $80 per order, and a carrying cost of $5 per unit per year. Calculate the EOQ. Discuss the significance of EOQ in inventory management and cost optimization. Analyze the potential benefits and limitations of using EOQ in managing inventory levels. Compare the EOQ model with the Just-in-Time (JIT) inventory system, highlighting the advantages and disadvantages of each approach. Consider the strategic implications of adopting JIT, such as reducing inventory holding costs, improving cash flow, and increasing supply chain efficiency. Discuss the challenges associated with JIT implementation, including supplier reliability and demand variability. Explain how EOQ and JIT can be integrated to achieve optimal inventory management and operational efficiency.
