Aspen DMC3 Builder - APC Project Step Testing and Commissioning Using a Virtual Plant

Develop hands-on experience for APC Project Step Testing and Commissioning using AspenTech's Virtual Plant, The Virtual Plant is a high-fidelity dynamic process model that responds like a real plant. Attendees will learn real-world control practice as they use the Virtual Plant to execute the Step Testing phase of an APC project. This course also teaches new control engineers essential process control concepts that have been traditionally learned on the job. Upon completion of this course attendees will have completed the equivalent of a full APC Step Testing and Commissioning.
