Abebooks is an online bookseller. It carries a product-specific amount of safety stock for each of its products. The retailer is exploring the possibility of increasing the order lot size for the inventory replenishments of each of its products so that it will replenish inventories less frequently and, therefore, save on ordering costs. The managers at Abebooks are wondering what would happen to their fill rates (fr) and cycle service levels (CSL) if they maintain their current safety inventory levels for each of their products, but increased the lot sizes of each of their products' inventory replenishments. Would fill rates go up, go down, or stay the same? Would cycle service levels go up, go down, or stay the same? Please state and justify your answer
