A computerized sensitivity analysis approach for modeling reliability of construction operations

The concept of construction safety is still an issue of concern for all engineering practitioners. The importance of structural and construction safety is associated with adverse consequences that may result from a structural failure or a construction accident. There are many factors which affect the safety of construction operations. Most of these factors are imprecisely defined and therefore, they are expressed in subjective measures rather than mathematical measures. The reliability of construction operations is dependent on the assessment of the various factors that affect the operations. The sensitivity level of the reliability of the operations to the state and frequency of each factor is incorporated into the reliability assessment process. A prototype computer program for sensitivity analysis of the factors is evaluated to assess the effect of the variability of the parameters of the factors on the reliability of construction operations
