Manufacturing AI Agents: Maintenance KB, QC SOPs & After-Sales Support

A manufacturing AI Agent serves line maintenance, quality, and after-sales: turn manuals, work history, QC SOPs, spare parts, and warranty policy into retrievable, cited, ACL-aware knowledge; attach read-only or semi-automatic MES/CMMS/ticket hooks; and force human handoff on safety, process-parameter changes, and high-value claims. It is not a ChatGPT tab on the shop floor, and not “dump every PDF into one KB.” GeonAI delivers Agents to plant boundaries and compliance; /agents are capability references only (not a public trial of all 363+ presets).

Why not one generic plant bot?

Document knowledge domains and write boundaries first: answer-only vs ticket create vs engineer confirm. Large plants and multinationals often need residency/private deploy—see /blog/deepseek-private-deployment-guide.

Scenario 1: Maintenance KB—retrieve and cite, do not “turn the wrench”

Core pattern: CMMS/manual RAG + asset/line ACL. Lookup by asset ID for inspection steps, alarm explanations, and past ticket summaries; answers need document version and section citations. Never invent torque, pressure, or electrical values; on miss, fixed degrade copy plus a ticket. CMMS may be read-only for status/spares; priority changes and work orders stay human. DeepSeek + RAG checklist: /blog/deepseek-rag-knowledge-base.

1. ACL by line/plant/contractor (contractors must not see core process parameters)
2. Chunk metadata: model, revision, effective date, language
3. Safety keywords (high voltage, LOTO, chemicals) → forced citations and optional forced handoff
4. Tie chat sessions to CMMS ticket IDs for shift handoff

Scenario 2: QC SOPs—effective version is the first guardrail

QC Agents reduce wrong-SOP lookups on night shifts and multi-plant drift. Prefer one controlled file source + effective-date filter: retrieve only the live revision; obsolete versions may be auditable but must not answer the floor. Agents can draft checklists and nonconformance talk tracks; changing disposition, release, or sampling plans stays human/QMS. Never let the model “estimate” tolerances or loosen specs.

• SOP change control and Agent index sync share one approval path
• Isolate knowledge by product family / customer spec
• QA sample floor answers: missing-citation and stale-SOP hit rates near zero
• SPC/QMS hooks prefer read-only; write-back needs separate review

Scenario 3: After-sales—policy RAG + tickets, not auto-payout

Equipment after-sales covers install guidance, first-pass triage, warranty scope, spare ETAs, and complaints. Fit: retrieve warranty/install knowledge → draft reply → create ticket / escalate. Out-of-warranty quotes, major claims, and personal-safety complaints → mandatory human. Channels may include web, WeCom, and dealer portals with one HQ policy voice. Module design: /blog/custom-customer-service-agent.

How to “wire” the three: split Agents, shared governance

Model matching: /blog/multi-model-selection-guide. Do not use one mega-prompt for both torque specs and external warranty promises.

Integrations: MES, CMMS, QMS, tickets

Go-live metrics (manufacturing-specific)

• Missing citation / stale SOP hit rate (QC near zero)
• Wrong parameter promise rate (torque, pressure, electrical)
• Safety handoff rate and missed-handoff rate
• Maintenance: time-to-correct section; repeat-question rate
• After-sales: FCR, wrong-warranty promise rate, ticket completeness
• Compliance: drawings/customer specs in prompts; residency review
