AI-Enabled PI Asset Framework Auditing
Dr. AF™ is an AI agent that audits your PI Asset Framework the way a 30-year expert would — and turns it into a measurable performance advantage. 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. Calculations quietly skip. Logic can misfire as dependency calculations get delayed. PI Vision slows down. Data sets feeding higher-level analytics and AI arrive late. Inefficient analytics drag on performance. And because it's all buried in the framework, no one sees it — until it shows up as wasted capacity, untrustworthy data, or a risk to the safety and operability of the plant. PI AF is the foundation of your entire analytics stack. A foundation that critical can't be left to chance.
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.
Auditing a new asset template? Dr. AF reviews it in progress and guides you to optimize performance — and every element inherits it.
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.
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.
A real audit review from a customer environment — every flag is a specific, measurable opportunity in your PI Asset Framework, categorized by rule, severity, and trigger type. This is what you get back from Dr. AF™.

Cells shaded when count > 0. Template counts multiply per element instance; element counts are per unique element.
Every flag corresponds to a specific analysis in your AF — each with an Original and a recommended Corrected version delivered in the workbook.
The Dr. AF package pairs the AI audit with hands-on expert consulting — including exception and compression tuning — to optimize performance across your full PI System, from how data is captured and stored all the way up to AF. AI to find it; an expert to help you get the most out of it.
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.
Tell us your deployment, model preference, and AF analysis count and we will provide a tailored quote. Not sure of your count? Start with a one-time, expert-run AF Health Check — the full Dr. AF audit workbook, with your data staying in your environment.
