Performance Evaluation of Organizations Based on Human Factor Engineering Using Fuzzy Data Envelopment Analysis (FDEA)

With the growing rate of incidents at the workplace and the consequent increase of staff’s dissatisfaction, this study attempts to examine an integrated ergonomic system in a pharmaceutical company. In this study, the organization performance is assessed at different levels. First, an ergonomic questionnaire determines the most effective factors in the efficiency of the system by the means of fuzzy data envelopment analysis (FDEA). The best FDEA model is selected by making perturbation in the data and calculating the correlation between rankings. Then, a standard questionnaire is distributed among the customers and the most important factor in customer satisfaction is discovered. At last, suppliers are ranked based on the most important criteria using Hierarchical TOPSIS method. Next, the most influential factors managers and expert’s performance in health, safety and environment section are measured and strategies are proposed for performance improvement. The information obtained from performance evaluation can identify the worker's performance efficiency.
