The Dr. AF™ Check-Up
You see a doctor to catch problems before they turn serious. The Dr. AF™ Check-Up does the same for your PI Asset Framework — an expert exam that diagnoses what's hiding in the foundation of your performance, data, and decisions, then prescribes the fix. Embedded knowledge. Embedded wisdom. Applied via AI.
Most AF teams don't know what they don't know. The rule set in Dr. AF™ cannot be found in existing documentation — it is from decades of gained knowledge and wisdom by Ales Soudek, THE global expert in everything AF. A suboptimal AF stays buried in the framework, quietly showing up as:
Analytics quietly fail to run — and no one is told.
Calculations and dependency chains fall behind real time.
Displays load slowly, frustrating the people who rely on them.
Recalculations and backfills drag on for hours.
The conditions that matter most slip by undetected.
Slow, late uploads starve higher-level analytics and AI.
If your PI Asset Framework isn’t healthy, there are consequences — and they compound. Bad data drives bad decisions, creating risk across safety, quality, environmental performance, and ultimately business performance.
Three parts, one outcome: a healthier, faster, more trustworthy AF.
The AI agent reviews your entire AF database against an expert rule base that exists in no documentation anywhere — distilled from Ales Soudek’s decades of knowledge and wisdom across hundreds of audits and mentoring sessions. It surfaces what experience teaches you to look for and returns it as import-ready findings.
Using Ales’s proprietary tools, your exception and compression settings are tuned together — not independently — and account for instrument class. The result: reclaimed storage and performance, without losing the fidelity that matters. Faster analytics, faster PI Vision rendering, and faster backfills.
One to two days of hands-on expert guidance (scaled to the size of your system) that turns the diagnosis into a prioritized plan of action — so the findings become real improvements, not a report on a shelf.
In the field, we’ve seen a 10% to 30% gain in PI System performance after a PI AF health check — and addressing the issues it surfaces.
Find the analytics quietly dragging your system down — and get the corrected version back. Do more, faster, on the infrastructure you already have.
Reclaim the headroom misconfigured analytics silently consume — instead of buying your way around it.
Sound governance, calculation health, and unit integrity mean your data reflects reality — so teams get it right the first time.
Run new templates and expressions through Dr. AF before deployment — a preventive check-up that confirms their “healthiness” and optimizes performance, so every element inherits a clean, healthy design.
Sharpen the PI System's ability to surface and alert on safety-critical conditions — vital when PI AF underpins mission-critical decision support.
Supercharge faster, proactive, intelligent real-time decision support — materially lifting operational performance.
The world's foremost expert on PI Asset Framework — the specialist behind your check-up.
Over 30 years and hundreds of customer audits, Ales developed a depth of AF knowledge and wisdom that exists nowhere else — distilled into the proprietary Dr. AF™ rule base. He was part of the team that developed the Sigmafine Framework — SF — while at Sigmafine in the mid-1990s, which evolved into AF after OSIsoft (makers of the PI System) purchased Sigmafine. Dr. AF applies that expertise directly to your database. Ales has spent months building the Dr. AF™ AI agent rule base — one that is unique, and that no SI nor any team at AVEVA can replicate, as these rules do not exist in any documentation.
Naming, structure, and standards.
Calculation health and performance.
Unit and type integrity.
The edge cases experience teaches you to catch.
Export your AF templates and elements to Excel — the standard PI Builder format.
The audit rule engine applies the embedded expert rule base across governance, analytics, UOM/casting, and edge-case best practices.
Findings come back with the Original analysis as it exists today alongside the Corrected version that brings it into compliance — across Summary, Template, and Element views.
Fixes that can be automatically corrected map directly back to your AF structure, so remediation is import-ready — and fixes that require more extensive changes come with guidance. Not a report you have to translate into action.
| Rule Group | Severity | Original | Corrected |
|---|---|---|---|
| Governance & Syntax | Critical | 68 | — |
| AF Analytics | High | 37 | 74 |
| UOM / Casting | Critical | 2 | 4 |
| Calculation Health | High | 5 | — |
| "Other" | Medium | 5 | — |
Representative output — 195 rows across a single PI AF database audit.
Choose the model that fits your organization. Both are sized by the number of AF Expressions in your environment. Pricing is provided on request.
A one-time perpetual right-to-use license that runs entirely in your environment — your AF structure never leaves your network. Best for larger and security-sensitive organizations.
A PIAFC-hosted assessment and support service. An annual subscription with updates, support, and consultation included — a managed option for teams that prefer it.
Licensing is tiered by the number of AF Expressions in your environment — taken directly from your AF Builder analytics. We size the right tier with you; pricing is provided on request and is never published.
Entry-level AF environments.
Growing AF deployments.
Substantial, mature AF estates.
Very large AF environments.
A single PI Server or plant.
Multi-site, enterprise-wide deployments.
For organizations that prefer no counting, an unlimited option is available on any model.
Perpetual includes first-year SRP; the 20% annual SRP (updates, support & consultation) applies from year two and is optional thereafter. Subscription is billed annually with those included.
