The purpose  this research is  survey the barriers and problems of using road-rail multimodal transportation in moving cargo and military cargo of a militia and to provide solutions to reduce these barriers and problems.

This current research is from mixed/combined kind using questionnaires. The statistical population of the research includes the senior managers of logistics, support, transportation, and mobility experts of the organization. In this research, firstly, through library studies and interviews with logistics and support experts and university professors, primary criteria and sub-criteria of barriers and problems of using road-rail multimodal transportation were extracted, and research questionnaires were compiled. Then these questionnaires were distributed among research experts. To determine the validity of the questionnaire, Lawshe formula was used, and to check the reliability the questionnaire, Cronbach's alpha coefficient was used. To determine the importance of these criteria and sub-criteria, the best-worst (BWM) method, which is a new approach in multi-criteria decision-making theory, was used.

In order to fulfill the purpose of the research, 41 sub-criteria were identified and categorized in four main criteria including "infrastructural barriers, safety and security actions barriers, managerial and technical barriers and financial barriers". In the first field research, validity and reliability of research criteria and sub-criteria were proved, and the best (most important) and worst (least important) criteria and sub-criteria in the barriers and problems using road-rail multimodal transportation in movement of cargo and military cargoes were calculated. In addition, in the second field research, the importance of these criteria and sub-criteria was determined by the best-worst decision-making method (BWM).

The results of research showed that main criterion "infrastructural obstacles" has the greatest effect on the use of road-rail multimodal transportation for moving cargo and military cargo. Also, the main criteria "management and technical obstacles, safety and security actions barriers and financial obstacles" are the next priorities.
