※ 引述《rajaccu100 (The 花)》之铭言:
: A motorcycle shop estimate that it will sell 750 motorcycle in a year.Each
: bike cost $300 , plus a fixed charge of $400 per order. If it costs $240 to
: store a motorcycle for a year , what is the order size and how many orders
: will be need in a year to minimize inventory costs?
: 顺便翻译一下^^ 感激不尽
译:
某家摩托车供应商估计一年可卖750台摩托车
每台车成本$300,每订购一次需$400
若储存一台摩托车一年需$240
则一次要订多少台且一年要订几次才能让存货成本为最低?
由 Q=√(2D*Cb/Ci)
Q: 为每次订购数量
D: 为一年的需要量 (=750)
Cb: 为每次订货成本 (=400)
Ci: 为每件存货储存成本 (=240)
Q=√(2*750*400/240) = 50 (台/次)
则一年需 750/50 = 15 (次)
