一個關於供應鏈管理的題目 - 企管

請問版上的各位大大
小弟我手邊有個題目
是關於供應鏈管理的
可是 看來看去
查了蠻多資料還是不太會寫
可麻煩各位大大 幫幫小弟嗎？

Consider a supply chain consisting of a single
manufacturing facility, a cross-dock,
and two retail outlets. Items are shipped
from the manufacturing facility to the cross-dock facility
and from there to the retail outlets.
Let L1 be the lead time from the factory to the cross-dock facility
and L2 be the lead time from the cross-dock facility to each retail outlet.
Let L= L1+L2. In the analysis below, we fix L and vary L1 and L2


1. Compare the amount of safety stock in two systems,
one in which lead time from the cross-dock facility to a retail
outlet is 1 zero(i.e.,L1=L and L2=0) and a
second system in which the lead time from the
factory to the cross-dock facility is equal to
zero(i.e.,L1=0and L2=L)
2. To reduce safety stock, should the cross-dock
facility be closer to the factory or the retail outlets?
For this purpose, analyze the impact of increasing
L1, and therefore decreasing L2, on total safety stock.
