Aurora-VT (Vehicle Testing)
Aurora Optimizes the Vehicle Testing Process by Selecting the Best Vehicle Configurations to Minimize the Vehicle Count & Overall Schedule Duration.
To optimize a major automobile manufacturer’s vehicles for both nondestructive and crash testing, Stottler Henke infused its intelligent planning and scheduling system, Aurora, with domain-specific heuristics used in the vehicle task planning process, resulting in a circa 10% decrease in the total number of vehicles needed to complete the same test/crash suite within the same time constraints. That is, Aurora-VT (Vehicle Testing) meets the same goals as the auto manufacturer already set, but with about 10% fewer vehicles; Aurora-VT has also increased the capability and ease to ask ‘what-if’ questions to further improve the schedule: for example, how much faster the test suite could be completed with only 5% fewer cars, or how many cars would be needed to complete the suite 15% quicker. Some new vehicle models may require over 100 vehicles; to date, Aurora-VT has saved over 10 vehicles, which translates into millions of dollars in savings for only one new vehicle model.
Aurora-VT is fueled by sophisticated artificial intelligence that optimizes automotive test schedules in order to complete work in a given time window while minimizing the total number of vehicles required. Aurora determines how to use fewer vehicles while providing improved transparency into what types of delays will affect the actual end date of the test suite, which not only allows for fewer vehicles to be built, but for enough safety to be built into the schedule so that the project goals of completing all tests within the desired timeframe, and, at the end of the day, verifying the vehicle performs as designed, can be achieved even with the inevitable unexpected events that will occur during the testing process.
