Cargo transportation services are one of the basic activities of logistics. The quality of the services offered by the cargo companies to the customer varies from the cargo company to the cargo company. In addition, sometimes the cargos sent by the customers cannot reach on time shipping address and at some times the customers' cargoes may be lost and damaged during transportation. To avoid this, the customer has to send his/her cargo with a good cargo company. In the selection of the cargo company, many factors, such as payment to the cargo company, trust in the cargo company and the quality of the services offered by the cargo company, etc. are needed to be considered. Therefore, it is possible to choose the best cargo company by using MCDM (multi-criteria decision-making) methods. This study tries to fill three research gaps. Firstly, there are few studies in the literature regarding the evaluation of cargo services by using MCDM methods. Secondly, the number of studies related to the use of SWARA (Step-wise weight assessment ratio analysis) and CODAS (Combinative distance-based assessment) methods together are few in the literature. Third, the number of Turkish studies related to CODAS method is few in literature. This study proposed a combined model of MCDM consisting of SWARA and CODAS methods to fill the above three research gaps. Future studies can use the combined method proposed in this study to solve different MCDM problems, such as the selection of computer, supplier selection and, the selection of third-party logistics companies, etc.
