Tehran’s District 12, as one of the capital’s cultural and tourism hubs, hosts a collection of prominent cultural institutions and museums that serve as major attractions for domestic and international visitors. However, the absence of systematic planning for routing between these centers leads to wasted time and energy for tourists and diminishes the quality of their visitation experience. This study aims to optimize museum visitation routes in Tehran’s District 12, focusing on minimizing travel time and distance, by selecting 22 active and significant museums in the area as case studies. To achieve this, the mathematical model of the Open Traveling Salesman Problem (Open TSP) was applied within the framework of network analysis in a Geographic Information System (GIS) environment. Precise spatial data—including the geographic locations of museums and the local street network—were imported into ArcGIS software and processed using the Network Analyst tool. Travel cost matrices (based on time and distance) between all museum pairs were calculated, and optimal visitation routes were extracted and ranked using heuristic Open TSP algorithms according to the criteria of minimum time and shortest distance. Findings indicate that applying the Open TSP model within network analysis leads to the identification of significantly more efficient routes compared to conventional patterns or unplanned visits. Quantitative results show that, under normal (non-optimized) conditions, visiting all 22 museums covers a distance of 25.91 km with a travel time of 310 minutes, whereas the optimized proposed route requires only 9.896 km and 118 minutes of travel time. This improvement represents a 62% reduction in both distance and travel time. The study demonstrates the high efficiency of integrating combinatorial optimization models with GIS spatial analysis capabilities for urban tourism planning and can serve as a model for intelligent management of tourist visitation routes in other urban areas. The results enable informed decision-making and optimal planning for both group and individual visits, significantly enhancing the tourism experience by reducing time and physical costs.
 

The present article is an analysis of the formation and evolution of the city of Songhor in Islamic times. This research is descriptive-analytical in terms of purpose and method. And to collect the required data and information, library-documentary studies and field visits (observation, testing and interviewing) were used. Among the archaeological evidence and historical documents examined in this study include: pottery, gravestones of medieval Islamic times, religious and non-religious architecture, and springs and sanctuaries. Its field data is recorded and classified by time period. Reading and reviewing historical and archeological information related to the city of Songhor reveals the cultural and historical identity of the city during the Islamic period. The results show that Songhor city is based on fundamental elements such as: the mosque, government building, monuments, traditional market, neighborhoods and city fence which during Islamic history are related to specific hierarchy in relation to social, economic needs. Religious, political and city fix
