As the first volume to address all three areas of human reliability, error, and human factors in engineering maintenance, this text offers engineers a tool for dealing with the increasing problem of human error. Requiring little prior knowledge on the part of the reader, this work begins with history, definitions, and mathematical concepts. It then discusses maintenance environment, causes for error, types of error, typical maintenance errors, and useful design improvement guidelines to reduce equipment maintenance errors. The author includes eight methods considered useful for performing human reliability and error analysis and seven mathematical models.
