Production planning

Any business that makes things from shared parts or ingredients faces the same question: if I make more of this, how much of that can I still make? This tool answers it from the stock you have and names the part that runs out first. A bakery planning bread and pastries from the same flour and butter, or a shop building kits from shared pieces, would use it the same way.

Built for AngelFire Ammunition

A Kansas ammunition manufacturer in Saint Marys.

The problem

Every round of ammunition uses four components: a primer, a powder charge, a case and a bullet. Many products share the same ones, so committing primers to one caliber quietly lowered how much of several others could be made, and nothing showed that trade-off. Turning a production run into something customers could preorder also took several manual steps across separate systems.

What I did

I built a planning tool that reads the company's component counts, and the parts it has on order, from its accounting system. As parts are set aside for one product, it shows how many rounds of every other product the remaining stock can still make, and which part runs out first. A finished plan's stock is pushed to the online store, ready to list as a preorder.

The result

The tool puts the trade-offs in plain view, across 35+ round types. Planning takes less time, fewer runs stall for a missing component, and listing a preorder takes fewer manual steps.

Move a slider to commit rounds to a load. Every other load's ceiling updates, and the component that runs out first is named. Stock, loads and names here are invented.
