Aspen PIMS-AO

Overview

Aspen PIMS-AO (Advanced Optimization) is a cloud-enabled production planning software developed by Aspen Technology for refining, olefins, and chemical industries. The platform utilizes a proprietary non-linear optimization engine and AI-driven hybrid models to solve complex supply chain, feedstock selection, and product slate problems. By accelerating scenario analysis and multi-case evaluations through high-performance cloud computing, Aspen PIMS-AO helps enterprise energy and chemical operators increase operational margins and maintain strict compliance.

What it does

• Optimizes feedstock selection, product yields, and operational plans for refineries and chemical plants.
• Executes non-linear optimization using a proprietary mathematical solver built for complex industrial models.
• Leverages AI and reduced-order hybrid models to learn from historical operational plans and verify accuracy.
• Automates cloud-enabled parametric scenario analysis to evaluate market risk and operational constraints.

Who it's for

• Refinery & Chemical Production Planners
• Energy & Petrochemical Trading Desks
• Supply Chain & Operations Analysts
• Process Engineering & Operations Teams

Why it works

• Proprietary non-linear solver eliminates local minima issues common in standard LP solvers.
• Parallel cloud processing enables rapid execution of dozens of complex sensitivity scenarios simultaneously.
• AI-powered hybrid process modeling continuously improves planning accuracy against real-world plant yields.
• Integrated crude assay management connects live feedstock composition data directly into economic planning models.

Founder story

Aspen PIMS-AO was created by Aspen Technology (AspenTech), which was originally founded in 1981 out of MIT in Bedford, Massachusetts. To solve complex non-linear economic optimization challenges in modern oil refineries and steam crackers, AspenTech developed the PIMS-AO (Advanced Optimization) module in 2014. It introduced a purpose-built proprietary mathematical solver designed to replace general-purpose solvers, significantly speeding up complex processing calculations.
