This handbook covers the methods, tools and techniques used to determine and estimate the relative risks incurred in engineering designs that could have adverse consequences because of error. The text covers the human element as well as the classical aspects of mechanical, electrical and chemical designs that contribute to risk. Included are examples of real-life applications and case studies to illustrate the text. This interdisciplinary handbook relates to any industry whose products and services affect the general public, such as aircraft, transportation, nuclear industries, electrical power and electrical products.
