Webb1 juni 1993 · Eliciting management action: Using THERP to highlight human factors deficiencies for trip reduction programs. Conference Fuld, R; Cybert, S - Transactions of the American Nuclear Society, Supplement; (USA) Methods and criteria for performing human factors evaluations of plant systems and procedures are well developed and available. The technique for human error-rate prediction (THERP) is a technique used in the field of human reliability assessment (HRA), for the purposes of evaluating the probability of a human error occurring throughout the completion of a specific task. From such analyses measures can then be taken to reduce the likelihood of … Visa mer The technique for human error rate prediction (THERP) is a first generation methodology, which means that its procedures follow the way conventional reliability analysis models a machine. The technique was … Visa mer • It is possible to use THERP at all stages of design. Furthermore, THERP is not restricted to the assessment of designs already in place and due to the level of detail in the analysis … Visa mer • THERP analysis is very resource intensive, and may require a large amount of effort to produce reliable HEP values.
