Abstract
This paper investigated shield machine operation (SMO) errors involved in shield tunneling construction accidents based on the Technique for the Retrospective and Predictive Analysis of Cognitive Errors (TRACEr). Human errors are classified and identified at a coarse-grained task level in the TRACEr framework, which could cause failures to completely identify and analyze the human errors in a given accident. This motivated us to propose an adapted TRACEr to overcome the limitation. The adapted TRACEr incorporates hierarchical task analysis (HTA) to decompose a task into combinations of activities, which helps describe human errors at a fine-grained activity level. The connection between the added activity level and the cognitive functions was constructed according to the Phoenix method. Based on the adaptation, an activity-oriented structure of human error taxonomies was developed, and a corresponding retrospective analysis procedure that focuses on identifying errors under various construction operational situations was proposed. Based on the adapted TRACEr, SMO errors were identified and analyzed. The error taxonomies of SMO were developed, and 72 accidents were retrospectively analyzed to identify and code the errors. Data mining techniques were applied to analyze the fine-grained SMO error data to reveal the main manifestations of SMO errors and the hidden associated rules for their cognitive failures. Consequently, several targeted cognitive-based human error mitigation strategies were proposed, showing the application potential of the adapted TRACEr as a human error management tool in the construction industry.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
