4.5 Summary

The role of inventory in the supply chain is well appreciated and it is generally agreed that inventory plays a vital role in ensuring the smooth processing of customer demand in an environment of uncertainty. Inventory has the vital function of ensuring product availability under these conditions of uncertainty, and it has become imperative that safety stocks be maintained at various locations within the supply chain to meet the expected level of service.

The competitive market environment requires that firms minimise costs in all activities, and one way in which cost savings can be achieved is through a reduction in the level of safety stock without jeopardising service quality. The most successful strategy for reducing the aggregate level of safety stock is centralisation of inventory and risk pooling. There is also increasing emphasis on improving the inventory turnover ratio and increasing inventory visibility in order to reduce the average level of inventory related costs.
