[单项选择]

 

(一) 金都公司是国内一家大型制造企业，为了便于商品的销售，他们将产品存放在分布于全国各地的12个分拨中心，每个分拨中心都建有仓库和自己的车队，为其所在的整个地区提供销售服务。大批量运输使得工厂能以经济批量进行生产。各工厂按周计划生产，尽量减少按月计划生产所出现的预测误差，降低误差的影响。 各分拨中心每种产品的基本库存水平是在历史销售水平的基础上确定的。如果是新产品，就根据目标客户及其估计销量来确定存储地点。 金都公司用商品完好率来衡量其运营业绩，并将其简称为客户服务。分拨中心DRP系统是其效率的充分保证。 请结合以上案例回答下列问题：

 

金都公司在N地现有9个仓库，总库存量价值为1500万元，金都公司要求通过增加仓库数量将总库存量价值控制在2000万元。根据库存的平方根定律，仓库数量应增加为（）个。
A. 16
B. 25
C. 18
D. 36
