In a particular organization, a typical customer order, when served from
the finished goods inventory has a lead time of 2 days. If it is served
by assembling to order, packed, and transported, the lead time is 8 days.
Finally, if it has to be made to order through the entire supply chain,
the lead time is 30 days. Assume that on an average, only half the orders
can be fulfilled from the finished goods inventory. What is the maximum
percentage of orders that should be required to be madetoorder, to achieve
an average ordertodelivery lead time of 5 days?

Consider the following three stage, linear supply chain process:
Figure 1: A linear supply chain process

Assume the cycle time process in the individual stages to be normally
distributed with parameters
respectively. Let the cycle times be denoted as X_{1},
X_{2},
and
X_{3}, respectively. Let Y be the supply chain lead
time, i.e. Y = X_{1}
+ X_{2} + X_{3}. Let
Z be the ordertodelivery
lead time, i.e. Z
= p_{1}(X_{1} + X_{2} + X_{3})
+ p_{2}(X_{2} + X_{3}) + p_{3}X_{3}
where p_{3} is the probability of fulfilling customer orders
from the finished goods inventory, etc. Assume p_{3}
= 0.5; p_{2} = 0.4; and p_{1} = 0.1. Assume
the following nominals and tolerances for the processes:
