Paper Title
A Fuzzy Structural Equation Model For Development Of A Safety Performance Index
Abstract
In this research, a framework is to be proposed to model the safety performance in construction sites.
Determinants of safety performance are to be defined through extensive literature review and a multidimensional safety
performance model is to be developed. In this context, a questionnaire is to be administered to construction companies with
sites. The collected data through questionnaires including linguistic terms are then to be defuzzified to get concrete numbers
by using fuzzy set theory which provides strong and significant instruments for the measurement of ambiguities and provides
the opportunity to meaningfully represent concepts expressed in the natural language. The validity of the proposed safety
performance model, relationships between determinants of safety performance are to be analyzed using the structural
equation modeling (SEM) which is a highly strong multivariable analysis technique that makes possible the evaluation of
latent structures. After validation of the model, a safety performance index assessment tool is to be proposed by the help of
software. The proposed safety performance assessment tool will be based on the empirically validated theoretical model.
