Replaces: a NETSTOCK spreadsheet row with no working shown
What the engine saysPlain English first, the arithmetic underneath
MSC East — Brentwood holds 0 free with 1 already inbound, which is 7 days of cover against a forecast of 0.1 a day. Numatic needs 8 days and class A carries 7 days of safety stock, so the target position is 3 units. Neither depot has spare cover, so buy 2 from Numatic.
Do nothing and MSC East — Brentwood is already out, so every order for this line goes short until something arrives. That is about 1 units of demand across the lead time. That is about £691 of sales at risk on this line alone.

Every figure on this page is the one the order will carry. Accepting the line copies none of it by hand.
Cover against lead timeFree stock running down, day by day
The blue line is free stock falling at the forecast rate. The dashed marker is the earliest a supplier delivery could land. Where the line reaches zero first, the depot is short and no amount of ordering on the day it happens will fix it.
