挑战

The company, a leading Asian refining company, was facing challenges in reducing planning run times while increasing solution quality. They wanted to gain time to explore complex, multiple price and operation scenarios and eliminate the occurrence of local optima. The company also wanted to increase internal customer satisfaction through faster response times to different business processes and have the ability to capture and explore more opportunities. The decision to expand the use of Aspen PIMS-AO was due to the recently enhanced global optimization capabilities with the new Aspen PIMS-AO V8.7 algorithm and the intention to explore the parallel processing feature for the maximum business impact.

解决方案

The company adopted Aspen PIMS-AO in 2008 due to its superior optimization capabilities. The parallel processing capability of Aspen PIMS-AO, combined with global optimization, exceeded desired results with the expanded use of the software. The company developed a work process to eliminate the occurrence of local optima by generating an optimized input solution and running the case stack varying the “epsilon” parameter. They tested several high-performance server machines to establish the optimal number of CPU cores and discovered that the optimal number of cores is 40. The company has successfully reduced their planning run times from 30 hours to 90 minutes with Aspen PIMS-AO, making the process 95% faster.
