Utilizing data envelopment analysis to benchmark safety performance of construction contractors

Incorporating Workplace Injury to Measure the Safety Performance of Industrial Sectors in Taiwan

“…Employee turnover leads to the loss of valuable knowledge and skills that employees have developed throughout their experience and training, and to the loss of organizational memory, which negatively affects a firm's productivity and business performance [4][5][6][7]. Thus, workplace injuries are unwelcome byproducts of economic activity [12,22]. Researchers have begun to consider workplace injury rates as unwelcome (undesirable) outputs in assessing the safety performance of business operations in a single sector or industry (e.g., [11][12][13][14]).…”

“…Thus, workplace injuries are unwelcome byproducts of economic activity [12,22]. Researchers have begun to consider workplace injury rates as unwelcome (undesirable) outputs in assessing the safety performance of business operations in a single sector or industry (e.g., [11][12][13][14]). This paper assumes that the three workplace injury rates are undesirable outputs.…”

“…Economic output and occupational injuries are intimately related [23,52]. Scholars agree that economic variables should be included in a measure of the safety performance [12,53]. Gross production value (y d ) represents actual economic results at the field level.…”

“…For example, Hermans et al [11] used the output-oriented Charnes-Cooper-Rhodes (CCR) model to evaluate road safety performance in countries and used the number of crashes and casualties as outputs. El-Mashaleh et al [12] incorporated five types of work accidents into the output-oriented CCR model to evaluate the safety performance of construction contractors. Shen et al [13] used the output-oriented CCR model to evaluate road safety performance in countries and considered mortality rate as an output.…”

Integration of Occupational Safety to Contractors` or Subcontractors` Performance Evaluation in Construction Projects

“…The data envelopment analysis (DEA), mentioned in second chapter of this paper, can be properly utilised to benchmark safety performance of construction contractors. Allowing, the approach of ElMashaleh [18] was deployed based on empirical data collected from 45 construction contractors. On a scale of 0 -1,0 DEA assesses the relative efficiency of every contractor relative to the rest of the contractors in terms of safety performance.…”
