How this simulator builds a load plan
Every KPI and chart segment traces back to the same deterministic sequence below. The goal is not “guessing” capacity—it is applying transparent rules so you can see cause and effect when demand, LBA, or minimums change.
1 · JIT on the due week
For each week’s demand, the engine first loads as much as possible on regular capacity in that same week (the due week). That volume shows up as JIT. This mirrors “make what is due now” before borrowing earlier capacity.
2 · Regular pre-build within local build-ahead (LBA)
What does not fit JIT is produced in earlier weeks using their regular capacity, stepping backward week by week. You cannot pull farther than your local build ahead setting allows. This is the core pull ahead bucket (purple in the chart).
3 · Overtime on the due week
After JIT and pull-ahead, remaining uncovered demand for that due week uses overtime capacity declared on that same week—not earlier weeks—before anything is marked late.
4 · Overtime pre-build within LBA
If due-week overtime is still insufficient, the simulator can use overtime capacity in earlier weeks, again only inside the LBA window. These units remain in the orange overtime bucket and are completed before their due week.
5 · Late catch-up in later weeks
Demand that still cannot be placed becomes late due demand. It is pushed forward, consuming regular capacity first, then overtime, in chronological order until the horizon ends. Whatever cannot be placed remains unresolved beyond the horizon.
6 · Minimum utilization smoothing
Separately, spare regular capacity can pull already-planned future regular work earlier within the same LBA window to support the minimum utilization target. This smoothing step never takes priority over the five demand-coverage steps above.
