Journal Article 2018 11 02 The purpose of this study is to provide a model of trust building process in the country's relief network considering the importance of establishing trust in the supply chain of humanitarian services as well as theoretical poverty in the field of trust building. To perform this study, three major recent events in Tehran province have been selected as a case study. Due to the lack of qualitative research in the field of trust building, using the grounded Theory, 2015 version of Corbin and Strauss, the model of trust building process in the relief network is designed and edited based on interview with 8 experts and members involved in the relief network. Given the importance of establishing trust between the members present in the relief network and the lack of a comprehensive model in this area, the present study aims to design a trust building model among members of the relief network and to examine the critical role of trust in the successful relief process and its reflection.The research findings are classified in three phases of conditions, actions and outcomes. The weak structures of the society and the community management system are a major obstacle to building trust. And insufficient funding, lack of certainty, unsuccessful performance, lack of coordination and cooperation between responsible groups and lack of preparation are the main sources of distrust. The most important finding of this research is the lack of trust in the humanitarian supply chain due to the reliance on public assistance.
