Aspen PIMS: Enhance Planning Results through DR to AO Migration

To provide an intensive problem-solving workshop designed for the intermediate Aspen PIMS user. Detailed emphasis is placed on reviewing Aspen PIMS modeling techniques and troubleshooting errors and warnings in Distributive Recursion (DR) and Advanced Optimization (AO) models.

Audience:

Participants who are familiar with Aspen PIMS and would like a more detailed understanding of the inner workings of the Aspen PIMS system and want advantages of the expanded capabilities of the Aspen PIMS Advanced Optimization software.

Training Details

  • Course Id:

    RPA231

    5 day(s)

  • CEUs Awarded:

    3.5

  • Level:

    Intermediate

Benefits

  • Learn how to correctly use intermediate level PIMS tables
  • Develop more sophisticated Aspen PIMS models and understand how the matrix structures are generated
  • Develop troubleshooting skills to analyze and solve model problems
  • Learn how to migrate model from PIMS DR to PIMS AO 
  • Gain familiarity with the XNLP and XSLP technologies
  • Use Advanced Optimization Analysis tools to evaluate various scenarios and deviations from optimal solution
  • Execute different Global Optimization procedures
  • Add and edit non-linear formulas to model

Approach

  • This course is oriented toward the practical aspects of refinery operations and planning.
  • Challenging class problems have been designed to illustrate advanced modeling techniques which are used to solve real planning problems. Students learn how Aspen PIMS table entries impact the model at the matrix level.
  • This course also covers approaches to debugging and troubleshooting an Aspen PIMS model. One of the workshop sessions leads the student through analytical steps required to debug a model and migrating to PIMS AO.
  • Class lectures describe the differences between standard Aspen PIMS using Distributed Recursion and Aspen PIMS Advanced Optimization using the XNLP framework, and focus on the use of the new functionality.
  • The features of Aspen PIMS Advanced Optimization are thoroughly described in lectures and demonstrations.
  • Class problems are designed to familiarize the student with the features of Aspen PIMS Advanced Optimization. Time is allotted to allow the student to explore these features.
