The most categorization of the collision data is a complex task requiring a high level of comprehension and skill. Hence for each contributing error, the following sections present and discuss the generic heart task type and the epcs and their impacts, culminating in an overall probability of failure. Heart+ is the reviewed, revised and extended version of the human error assessment and reduction technique.
It is a human reliability assessment technique developed to help risk analysts identify the major influences on human performance and the likelihood of error, in a systematic and repeatable way. It is based on the general principle that for each task in life there is a basic probability of failure. For the first time, it has been documented in a manual for general
This study aims to develop maritime accident assessment and reduction techniques in terms of technical understanding of the risk and safety linked to human factors. Abstract human reliability assessment is an essential work to guarantee the safety of locomotive driving process. Application of heart involves the identification of a generic task type to which is assigned a range of human unreliability values as well as a suggested proposed nominal value. Human error assessment and reduction technique (heart) 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.
This research provides a framework and methodology using the human error assessment and reduction technique (heart) and human factor analysis and classification system (hfacs), as an analysis tool to identify contributing factors, their impact on human error events, and predict the human error probabilities (heps) of future occurrences.
