Case Study: Leading Asian Refining Company achieves 95% faster planning and zero local optima with Aspen Technology's Aspen PIMS-AO

World Leader in Refining Reduces Planning Run Times from Hours to Minutes and Achieves the Most Profitable Solutions

Leading Asian Refining Company, a Fortune Global 500–ranked refiners operating the world’s largest refining hub with over 700,000 BPD capacity, faced long planning run times, the risk of local optima, and limited ability to explore multiple price and operations scenarios. To address these challenges they worked with Aspen Technology and expanded use of Aspen PIMS-AO to shorten response times, validate global solutions, and enable broader scenario analysis.

Aspen Technology implemented Aspen PIMS-AO’s global optimization and parallel processing (including multi-start, parametric analysis and optimizing server cores to 40) and applied best-practice workflows. The result: planning solves dropped from 30 hours to 90 minutes (a 95% reduction), consistent achievement of zero local optima, faster scenario exploration and improved crude trading capture and internal satisfaction—outcomes driven by Aspen Technology’s Aspen PIMS-AO capabilities.
