Balancing Lifecycle Sustainment Cost with Value of Information during Design Phase

2020-04-14
2020-01-0176
The complete lifecycle of complex systems, such as ground vehicles, consists of multiple phases including design, manufacturing, operation and sustainment (O&S) and finally disposal. For many systems, the majority of the lifecycle costs are incurred during the operation and sustainment phase, specifically in the form of uncertain maintenance costs. Testing and analysis during the design phase, including reliability and supportability analysis, can have a major influence on costs during the O&S phase. However, the cost of the analysis itself must be reconciled with the expected benefits of the reduction in uncertainty. In this paper, we quantify the value of performing the tests and analyses in the design phase by treating it as imperfect information obtained to better estimate uncertain maintenance costs.

Standard Practice for Human Systems Integration

2020-02-13
WIP
SAE6906A

This Human Systems Integration (HSI) Standard Practice identifies the Department of Defense (DoD) approach to conducting HSI programs as part of procurement activities. This Standard covers HSI processes throughout design, development, test, production, use, and disposal. Depending on contract phase and/or complexity of the program, tailoring should be applied. The scope of this standard includes prime and subcontractor HSI activities; it does not include Government HSI activities, which are covered in the DoD HSI Handbook. HSI programs should use the latest version of standards and handbooks listed below, unless a particular revision is specifically cited in the contract.

Aircraft Virtual Flight Testing and Certification in Off-nominal Multifactorial Situations

The behavior of a 'pilot-automaton-aircraft-operating environment' system (the System) in off-nominal situations with multiple risks can be unpredictably dangerous. Most multifactorial flight scenarios (corner cases) are considered as theoretically improbable. Such anomalies do nonetheless occur in operations and can lead to inconceivable accidents - 'black swan' events.

A Fast Running Loading Methodology for Ground Vehicle Underbody Blast Events

2018-04-03
2018-01-0620
A full-system, end-to-end blast modeling and simulation of vehicle underbody buried blast events typically includes detailed modeling of soil, high explosive (HE) charge and air. The complex computations involved in these simulations take days to just capture the initial 50-millisecond blast-off phase, and in some cases, even weeks. The single most intricate step in the buried blast event simulation is in the modeling of the explosive loading on the underbody structure from the blast products; it is also one of the most computationally expensive steps of the simulation. Therefore, there is significant interest in the modeling and simulation community to develop various methodologies for fast running tools to run full simulation events in quicker turnarounds of time.

Effective Decision-Making A Methodology Approach

Effective decision making is critical to maximizing profit/minimizing expenses, return on capital spending, and operational efficiency. To understand the impact of decisions that affect the enterprise, professionals at every level must secure and integrate relevant cross-functional information. Register for this seminar and learn skills needed to base decision making on solid business knowledge and sound financial principles instead of on emotion or "your gut." The instructor walks you through the tenets of structured decision-making and teaches a step-by-step approach to make practical, effective decisions.
