Lee, S (2001) Simulation analysis of productivity variation affected by accident risk in underground construction operations. PhD thesis, Purdue University, USA.
Abstract
The construction industry has had a disproportionately high rate of accident for its size. Accident statistics have played an important role as a prime indicator for measuring safety performance as well as a framework for evaluating accident prevention programs. However, the current system of statistics collection is based upon post-accident analysis. These data provide factual information regarding the post accident situation, but ignore conditions existing prior to occurrence of the accident. This study discusses the identification of factors affecting safety performance in trench operations in order to analyze their effect to the risk of accidents and estimates the risk of accidents by estimating the probability of accidents due to the fuzzy-based effect of the factors prior to the occurrence of an accident. The quantitative variation in productivity resulting from the probability of accidents is simulated based on MicroCYCLONE simulation to reflect the impact of accident risk on productivity and the potential savings possible can be presented. This provides insights into the relationship between the accident risk and their associated productivity variation. This study can contribute to helping those who are in charge of the safety in construction sites make more appropriate decisions to ensure the safe and cost-effective work activities regarding safety management.

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
