Agentic Supply Chain: PAR Level Optimization on Databricks

1. Problem / Context

Hospitals and clinics walk a tightrope between overstocks and stockouts. Excess inventory ties up cash, bloats carrying costs, and increases waste from expiry. Stockouts, on the other hand, delay procedures, force expensive rush orders, and erode clinician trust. Mid-market providers feel this acutely: lean supply chain teams manage hundreds of SKUs across ORs and clinics, often with limited analytics support and fragmented systems. Traditional PAR level setting is manual, based on outdated averages, and rarely re-evaluated as case mix, supplier lead times, and seasonality shift.

Agentic AI on Databricks offers a pragmatic path forward: continuously monitor consumption, reason about future need, and propose right-sized PAR levels and reorder plans—keeping humans in control while reducing firefighting.

2. Key Definitions & Concepts

• PAR Levels: The minimum on-hand quantity to trigger replenishment for a SKU at a specific location (e.g., OR core, procedure room). Right-sized PARs reduce both waste and stockouts.
• Agentic AI: Software agents that observe data, reason with policies and forecasts, and act via workflows (e.g., creating a replenishment suggestion) with human-in-the-loop governance.
• Databricks: A unified platform for data engineering, analytics, and machine learning that enables governed pipelines, feature computation, model training, and scheduled jobs without locking into a single application vendor.
• MMIS: The Materials Management Information System holding item masters, purchase history, on-hand balances, and supplier data.
• Usage Logs: Consumption signals from OR and clinic workflows—pick lists, case carts, returns, and documented use—that inform demand patterns.

3. Why This Matters for Mid-Market Regulated Firms

Mid-market healthcare organizations must improve working capital and reliability without adding headcount. They face audit expectations, privacy constraints, multiple suppliers, and complex EHR-MMIS-ERP landscapes. An agentic approach lets a small team punch above its weight by:

• Systematically optimizing PAR levels and reorder timing.
• Reducing rush orders and courier fees.
• Lowering carrying cost and expired product waste.
• Avoiding vendor lock-in via interoperable pipelines and neutral connectors.

Kriv AI, a governed AI and agentic automation partner for the mid-market, helps teams operationalize this approach with data readiness, workflow orchestration, and guardrails that satisfy compliance while delivering measurable ROI.

4. Practical Implementation Steps / Roadmap

1. Data Ingestion on Databricks
   • Land MMIS extracts: item master, vendor/contract, purchase orders, receipts, on-hand balances, locations, lead times.
   • Land usage signals: OR/clinic pick/return logs and charge capture; optional schedule calendars to flag expected volume.
   • Normalize and map top 50 high-impact SKUs (by spend, volatility, or criticality) to locations; establish quality checks for duplicates, outliers, and missing lead times.
2. Baseline and Constraints
   • Establish current PARs, min/max rules, and shelf-life/lot constraints.
   • Compute demand variability and lead-time reliability per SKU-location; set safety stock bounds that reflect clinical risk.
3. Weekly Recommendation Loop
   • Forecast near-term consumption using recent usage and schedule context.
   • Propose updated PAR levels and reorder quantities per SKU-location.
   • Include explanations: “Usage up 22% over 6 weeks; vendor lead time slipped from 7 to 11 days; recommended PAR +15%.”
   • Route suggestions to approvers (supply chain leads, OR materials managers). Acceptance can trigger a purchase suggestion or PO in the MMIS/ERP.
4. Human-in-the-Loop and Rollout
   • Start with read-only recommendations emailed or shown in a dashboard; collect feedback.
   • Move to semi-automation: accepted suggestions auto-create purchase requisitions; rejected ones capture reasons to refine logic.
   • Scale beyond the first 50 SKUs after performance hits targets; maintain vendor neutrality by supporting multiple supplier interfaces (API, EDI, flat files).
5. Pilot-to-Production Controls
   • Use scheduled jobs for weekly runs; version every model, rule, and policy; back-test against a baseline.
   • Keep a clear escape hatch: revert to current PARs if KPIs degrade or vendor service changes.

Kriv AI often assists by hardening data pipelines, instrumenting approvals, and building the agent orchestration so lean teams don’t carry the integration burden.

5. Governance, Compliance & Risk Controls Needed

• Privacy by Design: PAR optimization typically does not need PHI. If usage logs contain identifiers, mask or aggregate to remove patient identity. Apply least-privilege access.
• Auditability: Capture versioned recommendations, approvals, overrides, and resulting orders. Maintain an immutable log to support internal audit and external reviewers.
• Model Risk Management: Treat forecasting and policy rules like models—document assumptions, monitor drift, and set guardrails (e.g., max +/- 20% PAR change per week unless approved).
• Human Oversight: Keep an approval step for critical SKUs or high variance recommendations; route exceptions to senior reviewers.
• Vendor Neutrality: Avoid proprietary item IDs and lock-in; maintain crosswalks and connectors for multiple suppliers.
• Safety and Rollback: Implement thresholds that trigger reversion to last-known-good PARs if stockouts rise.

Kriv AI emphasizes a governance-first approach: RBAC, lineage, approvals, and policy-as-code so operations will trust automation—and auditors can verify it.

6. ROI & Metrics

Measure what matters, weekly and monthly:

• Inventory Days on Hand: Target a 10–20% reduction for the first 50 SKUs.
• Rush Orders: Track count and premium shipping costs; aim for 25–40% fewer rushes in targeted locations.
• Carrying Cost: Use weighted average cost of capital and holding cost assumptions to estimate dollar savings from lower average on-hand.
• Waste/Expiry: Monitor write-offs; expect 15–30% reduction as PARs right-size.
• Stockout Rate: Count incidents that delay cases; measure change against baseline.
• Process Time: Minutes saved per week in PAR reviews and ordering.

Example: A 250–300 bed community hospital begins with 50 OR and clinic SKUs (sutures, drapes, implants with constrained shelf-life). Weekly agent recommendations reduce average on-hand by 12%, rush orders by 32%, and waste by 18% within 90 days—freeing six figures of working capital and cutting courier fees, with a payback of 3–4 months.

7. Common Pitfalls & How to Avoid Them

• Boiling the Ocean: Don’t start with every SKU. Begin with the top 50 and expand in waves.
• Dirty Data: Inconsistent item masters and missing lead times torpedo recommendations. Fix crosswalks and run automated quality checks.
• Over-Automation Too Soon: Keep approvals early on; promote to auto-PO only after hitting KPI thresholds.
• Ignoring Supplier Reality: Recommendations must reflect actual lead-time variance and substitutions. Ingest vendor performance signals.
• Lock-In Risk: Build vendor-neutral connectors and maintain item crosswalks to avoid being trapped by a single supplier or app.
• No Feedback Loop: Capture acceptance/rejection reasons; use them to refine policies and forecasts.

30/60/90-Day Start Plan

First 30 Days

• Confirm objectives and KPIs (days on hand, rush orders, waste).
• Inventory the top 50 SKUs and locations; gather MMIS extracts and usage logs.
• Stand up Databricks pipelines; implement data quality checks and item crosswalks.
• Define governance boundaries: access, masking, approval roles, and audit logging.

Days 31–60

• Launch weekly recommendation runs; surface human-readable justifications.
• Implement approval workflows; track acceptance and overrides.
• Pilot vendor-neutral order creation (requisition or PO) after acceptance.
• Evaluate against baseline KPIs; tune safety stock and change limits.

Days 61–90

• Expand to additional SKU sets or locations based on results.
• Enable semi-automation for stable SKUs; keep manual review for critical items.
• Stand up monitoring dashboards and alerts; finalize rollback procedures.
• Present results to finance, supply chain, and clinical leaders; align on scale-out.

9. Industry-Specific Considerations

• Expiry and Lot Control: For sterile supplies and implants, incorporate lot/expiry and recall flags into recommendations.
• Consignment Items: Distinguish financial ownership to avoid overstating inventory savings.
• OR vs Clinic Dynamics: ORs have case-based spikes; clinics show steadier demand—use different bounds.
• EHR Integration: If using case schedules as a signal, rely on aggregated counts to avoid PHI exposure.
