Five new reads on every stock number: next buy, price index, obsolescence, aircraft, price position

A stock-number page used to be a record: cross-references, management data, the open requests, the buy history. This week it started drawing conclusions from that record. Five of them, each one a line or a panel on the page, each one rebuilt every night.

When DLA will buy it next

DLA buys most repeat items on a rhythm. From the procurement history we now state, per stock number, how often it buys, when it last did, and the expected window for the next buy. 11,525 stock numbers have a readable rhythm; 2,345 of them buy on a regular cadence; 2,815 are past their window today. The list of what is due or overdue, by supply class, is at /parts/due. The method was backtested by band before it went up.

What the government actually paid

The Government Price Index is one price per stock number: the median of the awards on it, the range, the last award and who won it, the twelve-month trend, and thirty-six months of history as a chart, with the FLIS list price and the lowest ask on this site beside it. Sellers can put the badge on their own website: it reads "Gov paid $X · PartsAndPlanes", links back to the page, and lives at /badge/gpi/<niin>.svg.

Whether it is going obsolete

Every stock number with government demand is scored for supply risk: the acquisition code says it is not stocked, it has a single or lapsed approved source, every source has let its SAM registration expire, it has been solicited for years without a buy, its data rights are restricted. Today that is 144 at high risk, 3,841 elevated, 15,666 on watch — and 6,968 of the flagged parts have an open RFQ this week. The list is at /obsolescence, by supply class and by aircraft; each stock-number page carries its own risk line with the reasons.

Which aircraft it fits

From the FLIS end-item and mission-design data we built 331 aircraft pages — /aircraft — with 469,408 part-to-platform links. F-16, H-60, C-130 and the rest: each shows the open RFQs on that aircraft's parts, the most-bought stock numbers, the vendors who win them, the parts at supply risk, and the supply classes involved. Each stock-number page now says which aircraft it fits.

Where your price would sit

On any DLA solicitation page there is now a price box. Type a unit price and it shows where that sits against the last thirty-six months of awards on that stock number, by quantity band, with the incumbent's share stated plainly: the last winner takes about 68% of repeat buys. It is built on 55,808 award pairs and checked on a held-out set. It is a position in the history, not a prediction, and it says so.

What it is not

None of this tells anyone what to buy, sell or quote. It describes what happened and what the record implies, the same for every reader. If a number is wrong on the page it is wrong in the nightly table, and it gets fixed in both.
