Using Cognitive Mapping Method in Designing of Sustainable Supply Chain Model in Type-2 Fuzzy Environment

Despite the importance of the service sector and its contribution to the world economy, studies on the supply chain of the service sector in comparison with the industrial sector are very rare The purpose of this paper are: identify effective concepts on the sustainable supply chain of hospitals, and design a sustainable supply chain model for the hospital.
This study is an applied descriptive survey. its nature is a type of qualitative and Delphi methods. At first, using deep interviews, effective concepts on the sustainable supply chain of the hospital were extracted. Then, using the Delphi method, the concepts were placed in the form of 15 main concepts. then, using of Type-2 fuzzy cognitive mapping method a causal model of sustainable supply chain were desined.
Effective concepts on the sustainable supply chain include 68 concepts that are in the form of the 15 main concepts such as: demand management, resource and capacity management, customer relationship management, supplier relationship management, service management, information management, financial performance management, Attention to the environment, contamination, energy consumption, legal requirements, employees, community and stakeholders, social accountability and business ethics. Based 15 concepts, the mapping of the sustainable supply chain of the hospital was designed. The results indicate that service delivery management is highly central among other concepts.
By focusing on concepts such as service management and capacity and resources management that have a high level of focus, a sustained supply chain supply chain can be improved.
