Explanation the relationship between total quality management system barriers using fuzzy combination approach (Gas Industry)

The Iranian organizations high tendency for the establishment of total quality management (TQM) system has caused the researchers also do significant research in recent years in this area. But the lack of attention to basic obstacles and challenges in the successful implementation of quality management systems in Iranian organizations has made does not provide the necessary settings for the full realization of this system. Identifying barriers of TQM using in organizations can be considered the first step in implementing these systems, because as long as the managers and staff have not action is to overcome these obstacles, failure of this project seems inevitable. In this study, after identifying the key barriers to successful implementation of TQM in the gas industry through literature review and interviews with experts, 5 main obstacles detected. Then the communication and sequence of barriers were determined with Fuzzy Interpretive Structural Modeling. Given that intensity of relationships between some obstacles was not clear in FISM method, therefor intensity of the relationship between barriers was determined by using of fuzzy Dematel. The results showed that human resources barriers and conceptual obstacles that must influential barriers be a lot of attention to them. The proposed model can provide a plan to tackle barriers to successful implementation of TQM in the gas industry.
