Abstract

"In the design of new products and systems, the mitigation of potential failures is very important. The sooner in a product's design mitigation can be performed, the lower the cost and easier to implement those mitigations become. However, currently, most mitigations strategies rely on the expertise of the engineers designing a product, and while models and for failure modes do exist to help, there are no guidelines for performing product changes to reduce risk. To help alleviate this, the risk mitigation strategy taxonomy is created from an empirical collection of mitigation strategies used in industry for failure mitigation, creating a consistent set of definitions for electromechanical risk mitigation strategies. By storing mitigation data in this consistent format, the data can be used to evaluate and compare different mitigation strategies. Applying this, the Generated Risk Event Effect Neutralization (GREEN) method is used to generate mitigation strategies for a product during the conceptual design of the product, where changes are the easiest to implement and cost the least. The GREEN method then compares and selects the best strategy based on the popularity, likelihood change, and consequence change that result from implementing the strategies"--Abstract, page iv.
