METHODS: This applied research was conducted based on a descriptive survey design. The statistical population of this research included the organizations and people involved in relief operations performed in three recent disasters: the fire-induced collapse of the Plasco building, Shahran gas explosion, and the flash flood in the Tehran subway. In order to analyze networks, a questionnaire containing network analysis questions was designed. Upon the completion of the questionnaires, the data of each network were entered systematically into a matrix on an excel spreadsheet. Such indexes as degree centrality, betweenness centrality, intersection points, isolation points, and network density were calculated by Ucinet and NetDraw software packages; therefore, the networks were analyzed. FINDINGS: Based on the results obtained from the analysis of communication, information exchange, and cooperation networks, the network density was 21%, indicating a low level of organizational relationship. At this level of communication, information exchange and cooperation were obtained at 11.5% and 16.5%, respectively. The analysis of the trust network also illustrated that the density of this network was 26.6%, suggesting that out of 21% of connections, there was about a quarter of possible trust. This is suggestive of low levels of inter-organizational Trust. CONCLUSION: Building trust in Iran's humanitarian service supply chain can be very effective in the acceleration of service supply, organization, and success of relief operations Humanitarian services, Network analysis, Supply chain, Trust 192 210 http://jorar.ir/browse.php?a_code=A-10-224-1&slc_lang=en&sid=1 Hamidreza Talaie H-talaie@araku.ac.ir 100319475328460012114 100319475328460012114 Yes Department of Industrial Management, Faculty of Administrative and Economic Sciences, Arak University, Arak, Iran Morteza Hajian 100319475328460012115 100319475328460012115 No Department of Management, Faculty of Administrative Sciences and Economics, Shahid Ashrafi University of Isfahan, Isfahan, Iran
