Capacity Margin Report

Classify Reserve

Capacity reports are easier to inspect when the margin and label are printed together. This program classifies a fixed capacity against selected demand.

Program

Play the program to choose demand and watch the reserve move from stable to watch to tight.

fn main() {
    let demand = ;
    let capacity = 100;
    let reserve = capacity - demand;
    let status = if reserve >= 25 {
        "stable"
    } else if reserve >= 10 {
        "watch"
    } else {
        "tight"
    };
    let line = format!("{demand} {reserve} {status}");
    println!("{line}");
}

reserve `reserve` is derived from capacity minus current demand.
classification The branch labels the margin as stable, watch, or tight.
deterministic inputs Capacity is a fixed fixture and demand is the only selector.
