Reliability-Based Design Optimization Software Package for Broader Simulation-Based Design Applications

It is critical to the US Army to have reliable ground vehicles that can be relied on to demonstrate consistently high levels of performance for survivability, mobility, and durability under a wide range of operational conditions without being subject to unanticipated premature failure, and with substantially reduced maintenance requirements. In response to critical Army needs and dual use in commercial applications, the project will develop computational reliability-based design optimization (RBDO) methods and software system. The proposed commercial software system, Reliability Analysis & Multidisciplinary Design Optimization (RAMDO), will be developed by using both sensitivity-based and sampling-based methods for reliability analysis and design optimization. The RAMDO software will have comprehensive capabilities including input distribution modeling for both independent and correlated random variables from experimental data; a variable screening method for high dimensional RBDO problems; statistical analysis; interval variable analysis; reliability analysis; RBDO; and confidence-based RBDO. For multidisciplinary simulation-based design process that is applicable to a diverse set of problems, RAMDO will be integrated with selected commercially available Process Integration and Design Optimization (PIDO) softwares. RAMDO will be installed on the TARDECs Dedicated Support Partition (DSP) on the Army Research Laboratorys (ARL) HPC system to support the project RBDO for Occupant Centric Protection.
