One of the most important topics that organizations are currently facing is the effective and efficient management of the supply chain. The main objective of this research is to rank contractors using the fuzzy analytic hierarchy process method. Firstly, existing frameworks for developing supply chain strategies are analyzed. Then this process is implemented to select the appropriate supplier in a case study. In this study, information on four criteria for evaluating contractors and information from three contractor companies is collected through interviews with experienced professionals. The contractor evaluation method in this research is performed by pairwise comparison of contractors, considering each criterion and its weight. Using the fuzzy analytic hierarchy process algorithm, relevant calculations are performed, and contractor companies are ranked. As a result, the best contractor is introduced to the company. This method can be used to improve supply chain management and enhance the quality and efficiency of supplier selection processes. Additionally, this method helps organizations make better decisions in the contractor selection process and achieve significant improvements in their supply chain performance.

In this study, the flood vulnerability of Bandar Abbas was investigated using the indicators of socio-economic status, urban density, population density and building quality and TOPSIS-hierarchical method. Therefore, at first, the weight and importance of the indicators were determined based on expert opinions and hierarchical analysis method. Then the vulnerability of the city to floods was calculated using the TOPSIS method. The study area was divided into 5 urban blocks, and then the decision matrix was formed according to 5 blocks and 4 indicators. Finally, the final map of Bandar Abbas urban flood vulnerability was prepared in ArcGIS software. The results of vulnerability analysis showed that the population density factor with a weight of 0.306 is the most important. Finally, the comprehensive analysis of Bandar Abbas flood vulnerability proved that the southern and central parts of the city and urban block No. 5 have higher vulnerabilities and these parts are a high priority for urban runoff and flood management. High population density can be one of the reasons for the vulnerability of this region to floods. The development of green space and increasing the capacity of the street runoff collection system are among the important measures to reduce urban flooding. Also, the spatial distribution of population density and urban density in Bandar Abbas was unbalanced and this issue should be considered in the management plans of this city to reduce the concentration of population in areas with high vulnerability.
