This thesis examines the optimal transportation in a chain of goods using the transit route of the North-South connecting corridor and the roads and railways of Astara to Bandar Abbas. The effectiveness and efficiency of combined transportation will be eva‎luated in this research, and the main goal of this research is to reduce transportation costs and times by using an advanced optimization model for the cuckoo search algorithm. At first, by reviewing the topic, the previous methods in the field of transportation optimization combined with the topic of location investigation and the concepts and capacity of each were analyzed. Then, in the third chapter, a mathematical model is presented to optimize this process, in which costs and times (including time costs) were considered as key factors. The results showed that this model achieves the most optimal route and method of transportation in this corridor by reducing transportation costs and times (10-20%). which includes 1916 kilometers long and 57 hours of time, and it costs about 38 cents per kilometer of travel. In this optimal route, 57% of the transportation route and 43% of the road transportation are used, and also the analysis of changes in transportation speed, interest rate, and other key keys is done, which makes the model stable and acceptable. Finally, suggestions for future research including dynamic and real-time data, examining economic, environmental, social impacts, and developing models for other international routes and other modes of transportation were presented. By presenting a comprehensive and acceptable model, this thesis can help improve performance and reduce costs in transit routes and provide suitable scientific research.
