Phases and timing
Describes RotoScheduler 0.3.3 · checked 2026-10-19 D5
The sample's RM-1 to RM-4 have fixed turrets: their arms move between the service station, the oven and the cooler together. At a close span, the fills show what each arm is doing.
The fills
| Appearance | Meaning |
|---|---|
| Grey | Service work, including charging molds and demolding parts. |
| Dark dots within service | Mold removal or mounting during a changeover. |
| Orange fill | Heating in the oven. |
| Light blue fill | Cooling. |
| Lighter continuation of a phase | Waiting after that station's work has finished. The hover calls this Slack. |
| White gap between stations | The turret moving to its next position, labelled Index move. |
| Dotted vertical line across the arms | A turret stop boundary. |
Hover a phase for its name, clock span, minutes and the basis of the timing. Default identifies the sample recipe's source; it is not a measured factory time. RM-5 and RM-6 use nominal cycle timing rather than projected phase fills.
The four statuses
| Status | How to read it |
|---|---|
Projected |
The day has a calculated timeline. Read any accompanying notes. |
Projected, process windows unknown |
Times have been calculated, but allowed process-time limits are missing. The sample states default limits, so a day reads Projected or, where a limit is exceeded, Conflict. |
Conflict |
The timing check found a conflict. Read the named arm, cycle and reason. |
Not projected |
A phase timeline could not be calculated for this machine-day. The inspector explains why. |
Projected times describe the plan, not what the factory did. From 0.3.0 a generated plan keeps to each day's clock and closes an arm's later cycles when they would end after the working window; see When the day's time runs out. Review both the plan's quantities and its timing notes.
More machine shapes are timed from 0.3.0: a ring with more stations than carriers, a loading crew that works two neighbouring stations, an arm that is switched off but still rides the ring, and a plain waiting position. A day that used to read Not projected for one of those reasons can now read Projected.
The note strip above the board says each of the engine's statements once, with a count of the places it applies to (({count} places)), and scrolls when a busy plant has more statements than fit.
