Plant Operations Center

Plant Operations Center is a mobile control room for shift leads and maintenance teams: line status, shift handover, incidents, work orders and spare parts for a site in one place – with a next step that puts safety ahead of restart, escalation and handover.

HIGHLIGHTS
• Site and line overview: running, reduced, changeover, stopped or maintenance, with reason, duration, rate per hour and a bottleneck ranking
• Shift plan for early, late, night or day shifts with planned and present staffing vs. minimum staffing, output and scrap
• Shift handover with checkpoints and a readiness score (0–100) that is frozen at handover; acknowledgment by PIN or in person, or an objection
• Incidents with line, equipment, category, severity and impact (stop, reduced, none), downtime minutes, root cause, corrective action and a complete timeline
• Escalation matrix per severity with configurable times, halved when a line is stopped; the app recommends the level, you document the escalation
• Restart checklist with mandatory steps by severity; release is confirmed by a second person with a PIN
• Equipment register with criticality A/B/C, condition and health score; preventive, corrective, inspection and calibration work orders with due dates, reminders and rescheduling with a reason
• Materials and spare parts with stock, minimum stock and blocked status; bottleneck list across staffing, materials, equipment and incidents
• Daily report with availability, performance, quality, OEE, MTTR, MTBF, downtime Pareto and maintenance compliance – calculated only from recorded data
• Evidence as photo, document or note with a SHA-256 checksum, stored encrypted
• PDF per incident and daily report, CSV per list with a manifest; names masked in exports by default
• Roles Owner, Manager, Contributor and Viewer with PIN; hash-chained audit log that every timeline is built from

PLEASE NOTE
The app documents and coordinates. It does not control equipment and does not replace your site's safety or release procedures; every release is confirmed by a person.
