Door Line — Capacity & Buffer Model

Tune the line parameters and read capacity, the binding bottleneck, feasibility and live buffer behaviour. Everything recalculates as you type.

Capacity per department

Required vs available capacity per day. Utilization over 85% is tight; over 100% is overloaded. Waiting = share of the station's run-time lost to a starved (empty) or blocked (full) buffer in the week-2 simulation. Max achievable = doors/day if that station is the limiter.

Scenarios

Max capacity per station (doors/day) and surplus / (shortage) against each target. Negatives in red mean that station cannot meet the target.

Powder coating — output per production day

Colors are coated largest-first: day 1 takes the highest-volume colors until the shift (hours/day) is full, day 2 (and 3) take the rest. Each curve is one coating day's cumulative output over its wall-clock — rising during a color's run and flat during the color change + coating-without-storage. The number of color changes follows from how many colors fit; days full of small colors carry more changeovers and run closer to the shift-end line. If a day's colors would pass the shift end, they spill to the next coating day; anything beyond the available days is reported as not feasible. Click a day in the legend to show or hide it.

Buffer simulation

10-minute steps over two weeks; measured over week 2. Coating fills Storage A with whole profiles in a sawtooth (runs and color changes); the CNC cuts profiles from A into parts in Storage B; Assembly (st.5) moves parts from B into Storage C; Final assembly (st.7) draws parts from C and finishes doors. If a station can't keep up, the buffer ahead of it fills and backs up the line. The safety stock is a reference line — the CNC dips below it when needed.
