Combine equipment condition, inspection records, and shift constraints into supervisor-reviewed maintenance coordination.

Illustrative architecture: A mine operations team sees recurring haul-truck faults while production plans and workshop capacity change across shifts. Supervisors need to understand equipment evidence, open inspections, parts, and crew qualifications before assigning work. Agents prepare coordination packets without controlling vehicles, ventilation, blasting, or safety systems.
Fault codes can repeat after an unresolved repair, telemetry links may be intermittent, and shift handoffs lose context. Optimizing maintenance solely around production targets can obscure inspection requirements or assume equipment is available when it remains restricted.
Condition, inspection, resource, and handoff specialists reconcile distinct operational records. Deterministic scheduling respects supervisor-approved constraints, and every proposal carries the equipment's authoritative restriction state.
The intended result is a reviewable operational decision with source evidence and explicit ownership. Measure evidence readiness and task ownership before attributing changes in equipment availability. Physical maintenance and safety decisions remain with qualified operational teams, whose actions should be distinguishable from agent preparation in the record.
Summarize fault history and operating context with telemetry quality flags.

Retrieve outstanding inspections, restriction records, and approved maintenance procedures.
Cannot waive inspections or close safety findings.
Match work scope to parts, bays, qualified crews, and approved windows.
Cannot commit unsafe work or override equipment restrictions.
Prepare a concise packet of open tasks, evidence, and named ownership.
Supervisors approve handoffs and work assignments.
Provide timestamped condition data and authoritative restriction status through read-only adapters.
Owns work orders, approved procedures, inspection findings, and qualified signoffs.
Track workshop capacity, crew qualifications, parts reservations, and handoff acknowledgements.

Identify stale telemetry and distinguish repeated historical codes from newly observed faults.
Retrieve unresolved inspections and previous repair evidence before proposing another maintenance action.
Apply bay, parts, crew, and approved access constraints; retain restriction state as a hard planning condition.
Present candidate work packages, missing evidence, and expected handoff ownership to the accountable supervisor.
Create the authorized work order and shift handoff, then await qualified completion evidence before changing operational availability.
Detect: Event timestamps and sequence numbers place the messages before the latest verified repair.
Recover: Retain them as historical evidence and avoid reopening work solely from receipt order.
Detect: The handoff remains unacknowledged beyond the configured shift transition window.
Recover: Escalate to the duty manager and keep the previous owner accountable until acceptance is recorded.
Measurement definitions, not promised improvements.
Open work items with evidence, owner, and acknowledged next shift divided by handed-off items.
Time from accepted new fault to supervisor-reviewable condition and maintenance context.
Historical reconnect events correctly excluded from new-fault triggers divided by audited stale events.
Approved packages with required parts, qualified crew, and current procedures divided by approved packages.
| Decision | Benefit | Cost |
|---|---|---|
| Offline-tolerant event handling | Preserves evidence from remote equipment. | Requires event ordering and duplicate reconciliation after reconnects. |
| Restriction-aware planning | Keeps operational constraints visible. | Production-oriented schedules may be less flexible. |
| Explicit handoff acceptance | Reduces orphaned tasks across shifts. | Requires supervisor participation and escalation coverage. |
Supervisors verify stale events, unresolved restrictions, and missing repair evidence across completed incidents.
One fleet group evaluates work readiness and handoff ownership without changing equipment status.
Work-order and handoff drafts launch after offline-reconnect and unaccepted-shift exercises pass.
