You want to check if the variability of transit time changes the choice of path. You found the following standard deviation in transit time at these point: time at Valparaiso port (5 days), transit time to Newark port (4 days), transit time to Houston port (2 days), time at Newark port (1 day), time at Houston port (2 days), truckload from Newark to Chicago (3 days), intermodel from Newark to Chicago (5 days), truckload from Houston to Chicago (3 days), and intermodel from Houston to Chicago (6 days). Across the four path options, what the lowest total lead time variability (lowest total standard deviation)?
Across the four path options, what is the lowest total logistics cost per 1000 liter of wine?
