business.unr.eduday is the standard deviation of demand per day, and LT days is the lead time expressed in days, then σ2 L = LT days ∗σ 2 day (4) To get the standard deviation of the LT demand (instead of the variance), we have to take the square root: σ L = q LT days ∗σ day. (5) Depending on whether we have the LT in days, weeks, or months, we can use ...
