SIMULATION / SA-EQP-TOOL-AVAILABILITY-001
Tool availability and queue state
Tool State
Read RAM, utilization, downtime, and queue-pressure vocabulary without creating dispatch, PM, or production workflow logic.
EXPLORE
Start with the observable.
Use this page when the simulation is the primary artifact. The linked lesson explains the concept; the linked lab keeps the visual replay surface available.
- Separate availability, utilization, scheduled downtime, unscheduled downtime, and queue pressure.
- Compare a baseline week, RAM improvement week, and dispatch-pressure week.
- Use the card to ask what event log, state definitions, owner review, and production context are missing.
RUN CARD
Conditions before conclusions.
The page replays saved equipment-state teaching data. It does not submit work orders, schedule maintenance, dispatch lots, or promise capacity.
Primary knobs
- Teaching weeks: baseline, RAM improvement, dispatch pressure
- Outputs: availability, utilization, downtime, queue-pressure index
- Review focus: equipment-state vocabulary before citing throughput or cycle-time claims
- Boundary: no work order, PM instruction, dispatch rule, production schedule, or capacity promise
Saved outputs
- weekly state table
- state-hour sum check
- availability improvement check
- queue-pressure check

How the number was made.
Methods are written for citation discipline: the extraction rule matters as much as the plotted value.
Represent each teaching week with productive, standby, engineering, scheduled, and unscheduled hours.
Keep this method attached when reusing the figure or metric.
Compute availability and utilization from explicit state-hour fields.
Keep this method attached when reusing the figure or metric.
Track queue pressure separately so higher utilization is not mistaken for better flow.
Keep this method attached when reusing the figure or metric.
Attach SEMI RAM/OEE vocabulary while excluding production dispatch and maintenance workflows.
Keep this method attached when reusing the figure or metric.
LIMITS
What this page does not claim.
The MVP is useful because the limits are visible. These statements prevent a teaching simulation from being cited as silicon evidence.
No maintenance instruction, PM plan, spare-parts action, work-order workflow, dispatch rule, production schedule, or capacity commitment is included.
Carry this boundary into any derivative note, paper draft, or slide.
No real tool event log, operator record, recipe context, failure mode, alarm handling, or root-cause result is represented.
Carry this boundary into any derivative note, paper draft, or slide.
The cases are teaching proxies and cannot rank equipment, justify staffing, or support production commitments.
Carry this boundary into any derivative note, paper draft, or slide.
Real reuse requires controlled state definitions, validated event logs, factory-owner review, EHS/process context, and qualified signoff.
Carry this boundary into any derivative note, paper draft, or slide.
EVIDENCE
Trace the claim back to artifacts.
The evidence route remains the catalog-level browser; this page is the simulation-level reading card.
The dataset preserves three weekly equipment-state teaching cases.
SA-EQP-TOOL-AVAILABILITY-001
Verification checks 168-hour closure, availability improvement, and queue-pressure behavior.
SA-EQP-TOOL-AVAILABILITY-001
The model card keeps PM, dispatch, production, and staffing boundaries explicit.
