下列各项中，关于存货成本说法不正确的是______

A．订货成本随着订货次数增加而增加
B．购置成本随着存货数量的增加而增加
C．缺货成本随着存货数量减少而可能增加
D．储存成本与存货数量无关，是一项固定成本

答案

参考答案：D

解析：订货成本包括一部分固定成本和一部分变动成本。变动成本随着订货次数的增加而增加，所以订货成本也会随着订货次数的增加而增加。购置成本是存货数量与单价的乘积，所以会随着存货数量的增加而增加。缺货成本随着存货数量的增加而下降，随着存货持有数量减少而上升。储存成本也包括一部分固定成本和一部分变动成本，变动成本部分会随着存货量的增加而增加，所以储存成本随着储存量增加而增加。
