Using ExtendSim to build virtual integrated (operations and logistics) models that consider all physical intermodal processes to measure the actions, effects, and responses within a system, WorleyParsons was able to validate design, assess sensitivities, and quantify operational risk to project - not just local risks to each process, but all interconnected risks through the logistics chain. Their models improved the quality of decisions, identified bottlenecks, and assisted with investment strategy for their clients by providing quantitative decision support and systems analysis through discrete event simulation. Their quantified recommendations positively impacted client operational design to the order of tens of millions of dollars.
