Aspen Petroleum Scheduler: Using Models for Daily Scheduling

Course Id:  RBS101   |   Duration:  2.00 day(s)   |   CEUs Awarded:  1.4   |   Level:  Introductory

Course Objective

Learn how to use Aspen Petroleum Scheduler effectively for daily scheduling operations. This course is geared for daily users rather than model developers.

Course Overview

  • Gain familiarity with key Aspen Petroleum Scheduler database and interfaces: Event and Flowsheet
  • Practice building and simulating a refinery model
  • Perform exercises in scheduling a variety of event types
  • Simulate/publish a schedule to the results database
  • Recognize and understand how Aspen Petroleum Scheduler facilities the overall planning and scheduling work process


Set up your processes in Aspen Petroleum Scheduler and observe the following benefits:

  • Increased throughput
  • Improved block switching
  • Reduction of quality giveaway
  • Elimination of crisis decision making
  • Better control over inventories
  • Reduced demurrage
  • Ability to evaluate special opportunities


  • Course is designed for anyone interested in learning how to use Aspen Petroleum Scheduler (APS): Event and Flow Sheet Interfaces.
  • Scheduling professionals that want to gain experience using APS -  "A Day in the Life of an APS Scheduler"


  • Instruction on basic topics
  • Instructor-guided demonstrations of features
  • Hands-on exercises
  • A comprehensive training manual
The course is divided into two parts:
  • PART I leads you step-by-step through building a model of a medium conversion refinery and scheduling the refinery operations in Aspen Petroleum Scheduler
  • PART II explains different processes including: simulation, publishing, overall scheduling and integration tools to build reports, getting data from tables, importing event and inventories


  • Microsoft Excel proficiency
  • General knowledge of Microsoft Access
  • Awareness of the interaction between refining technology operations and planning is strongly recommended Suggested Subsequent Courses
