ABSTRACT
Researchers have been continuously trying to improve human performance with respect to HSE and ergonomics; hereafter referred to as HSEE. This study proposes a non-parametric efficiency frontier analysis method based on the adaptive neural network (ANN) technique for measuring job satisfaction among operators with respect to HSEE. ln order to conduct this review, we have distributed questionnaires to four working shifts' operators in a gas refinery in which we used variety of questions related to HSE and Ergonomics. We have used ANN to predict the efficiency of HSE and Ergonomics and ranked the efficiencies. It should be noted that work groups have been used to satisfy the importance of teamwork in HSE and Ergonomics systems. By this approach, we assume some work teams according to some principles such as education, age and similarity in nature of works. The main objective of this article was Utilization of adaptive neural network for teamwork assessment versus HSE and Ergonomics. After defining system's efficiency against
different shifts operators and ranking them, we began analyzing the results inside working groups. At first, we compared performances of individuals with teams and reviewed the average of these two by using T-test. We then reviewed the performances of different work groups (teams) by using ANOV A F -test.
