AspenTech Acquires Apex Optimisation, Inventors of Generic Dynamic Optimisation Technology (GDOT)

Aligns Advanced Process Control with Planning & Scheduling to Unify Production Optimization

BEDFORD, Mass – February 5, 2018

Aspen Technology, Inc. (NASDAQ: AZPN), the asset optimization software company, has acquired Apex Optimisation, a European company specializing in Dynamic Optimization and Advanced Process Control.

Apex’s GDOT software aligns Advanced Process Control (APC) with Planning & Scheduling, enabling unified production optimization for refineries and petrochemical companies in complex industrial environments.

GDOT software dynamically processes hundreds of variables to achieve optimization, while driving closer alignment with planning and scheduling. Dynamic coordination captures economic incentives every minute across multiple units, which is critical for refineries and plants where operational complexity and changing conditions are the norm.

Customers using GDOT have experienced increased production, reduced quality variability and lower energy consumption with project paybacks that are measured in months. In addition to short-term economic benefits, dynamic optimization also improves the safety, reliability and operability characteristics of plant assets, contributing to more optimal long-term performance.

In a typical refinery, overall benefits of deploying GDOT can be comparable to those achieved by a significant deployment of APC. A single multi-unit application of GDOT may generate up to $10M per year, and many refineries have several implementations.

Through its ability to track changes in process unit behavior in real time, GDOT supports AspenTech’s Asset Optimization vision, improving the understanding of how changes in engineering models propagate to other areas of Asset Optimization applications -- including Planning & Scheduling, APC, Engineering and Design, as well as broader Supply Chain work processes.

Co-Founders Henrik Terndrup and Klas Dahlgren and their team of world-class dynamic optimization experts will join AspenTech as part of the acquisition.

The Australian services operations of Apex Optimisation will remain an independent entity, trading under the name Greenfern Dynamics Pty.
