Although the Iranian plateau has witnessed Paleolithic researches since the early twenty century, still little is known about the Paleolithic of Iran. There are several reasons for this situation and lack of scholarly enthusiasm on the part of Iranian archaeologists seems to be the most imperative one. Concerning the history of Paleolithic surveys and excavations conducted in Iran, three distinct phases are recognizable. First, from the beginning of the twenty century to the 1980 when numerous field missions were executed in this region all by western institutes, second phase observes a twenty years gap in the Paleolithic studies hence; only few surveys could be performed in this period, and the third phase starts with the reopening of the Iranian fields to the non-Iranian researchers, which led to the survey and excavation of handful of new Paleolithic sites. This article reviews Paleolithic researches conducted in Iran since the beginning of twenty century to the present time.

INTRODUCTION: The occurrence of a huge number of road accidents in Iran makes it necessary to pay more attention than before to the rescue and relief sector, the correct locating of road rescue and relief bases and its development and equipment, especially in Alborz province and topological conditions, geographical diversity and its tourism characteristics. Therefore, in this research, in order to reduce the hazards, the spatial analysis of rescue and relief bases in this province was conducted. METHODS: In this research, in order to optimize the allocation and locating the rescue and relief centers, the intended indicators were extracted from the Red Crescent Society instructions and after preparing the required data, the weight of each index was extracted and optimized in PSO algorithm in MATLAB environment using AHP hierarchical analysis and OWA weighted average. The obtained weights were applied in the corresponding layers and the optimal points were suggested for the development of the rescue and relief network of Alborz province. FINDINGS: Finally, prioritizing the development of rescue and relief centers in the province was suggested after evaluating the accident-prone state of the province in relation to the existing and proposed centers as well as the development plans of the province CONCLUSION: The results showed that the use of PSO algorithm can have acceptable results in the field of optimal locating of rescue and relief centers.
