TSRB SIS Queue
Short-Interval Scheduling • Constraint Execution
Built for flow, not forecasts
Locks the bottleneck for 2–4 hours
Readiness gate for NEXT 3
Finish what you start—
and stop starving the constraint.
TSRB’s Short-Interval Scheduling (SIS) Queue turns “the plan” into a
Now–Next–Later execution contract for the bottleneck.
It keeps the constraint running by locking execution, enforcing readiness, and
governing exceptions with visible rules and audit trails.
Freeze Zone (Do Not Interrupt)
A time‑boxed execution guarantee for the bottleneck—no emotional re‑sequencing.
NEXT 3 Readiness Gate
Material, tooling, operator, QA: red indicators predict stoppage before it happens.
Break‑Freeze by exception
Change is allowed only when it’s justified, classified, and authorized—then logged.
Proof & audit trail
Every swap, pause, and escalation is recorded to build discipline and stability.
What the queue looks like
Now is locked. Next is staged. Later is visible—without temptation.

Why SIS beats “schedule by spreadsheet” on the shop floor
Most instability isn’t a planning problem—it’s an execution contract problem.
SIS is the missing layer between the scheduler and the line.
🎯
Protect the bottleneck
If the constraint stops, throughput stops. SIS keeps it fed with staged, ready work.
🔒
Remove emotional re‑sequencing
Freeze creates a “finish what you start” discipline—change requires authorization.
🧭
Expose the real causes
Readiness and compliance reveal why flow breaks: missing kits, tooling, QA, labor, or reliability.
“95% availability can still feel like chaos.”
SIS targets the behaviors underneath: micro‑stops, readiness misses, changeover churn, and repeated exceptions—so the team can run stable stretches.

“If it’s allowed, it’s logged.”
Every break‑freeze, swap, pause, and escalation becomes governed work with timestamps and accountability—so improvement doesn’t depend on tribal knowledge.

— Execution discipline that survives shift change
How it works
A simple pattern that teams actually follow—because the system makes the right thing the easy thing.
1
Publish the interval contract
Scheduler outputs the next constraint sequence. SIS converts it into Now–Next–Later.
2
Lock the Freeze Zone
Commit 2–4 hours of constraint work. Inside freeze, changes are rule‑gated.
3
Enforce readiness for NEXT 3
No surprises at the constraint: material, tooling, labor, QA validated before release.
4
Govern exceptions
When reality deviates, classify and authorize actions, then log outcomes to learn.
Key idea: SIS is a separate execution layer over the scheduler—built for short intervals, human handoffs, and controlled changes.
It doesn’t replace planning; it makes planning executable.
Value by role
Different people care about different “wins.” SIS speaks their language—without compromising flow.
🧠
Schedulers & planners
Your plan becomes real: fewer mid‑shift overrides, fewer “hot job” surprises, and a clear feedback loop on what broke execution.
⚡
Operators & supervisors
Clear NOW ownership, staged NEXT, and permissioned actions. Less arguing, less hunting, more stable rhythm.
📊
Plant leadership
Throughput stability without heroics. Repeatable handoffs, fewer start/stop cycles, and visible root causes of flow loss.
🛡️
Quality & maintenance
Early warning via readiness and compliance drift. Engage before the constraint stalls, with auditable calls and outcomes.
🔧
IT / ERP owners
SIS runs on clean, relational data (PostgreSQL‑friendly). Clear boundaries: ERP remains the system of record; SIS drives execution.
💰
CFO / finance
Reduced expediting, overtime churn, and schedule whiplash. More reliable ship dates because the bottleneck stays productive.
Integrations (practical, not theoretical)
Pull the plan from your scheduler/ERP, pull reality from the shop floor, and push governed decisions back as signals.
🧾
ERP & routing
Work orders, operations, standards, due dates, priorities, and constraints—mirrored into the SIS data model.
🏭
Shop‑floor events
Machine state, counts, downtime reasons, and pace—so “running” is verified, not assumed.
🧱
Governed actions
Break‑freeze requests, escalations, and handoff confirmations become structured events with timestamps.
Deployment‑friendly: SIS can run on‑prem or controlled cloud.
It’s designed to sit over your scheduler—without rip‑and‑replace.
Data model hint: high‑volume events append-only; interval summaries materialized for fast scoreboards; transactional tables for plan/dispatch.
