  Nowadays, the complexity and entanglement of financial markets are under the influence of various variables and problems which classical financial sciences are generally unable to solve. This has motivated new approaches in financial sciences like dynamic complex networks. The current research has used the dynamic complex network approach, empirical mode decomposition, and grey relational analysis to investigate the systemic risk of Iran's capital market banks from the beginning of 2015 to the march 2021. For this purpose, first, by building a sliding window, it has calculated the correlation coefficient of stock and then the index of the complex network. Using the results of empirical mode decomposition and grey relational analysis through Engel - Granger causality statistical test,, showed a close and long-term relationship between stock market fluctuations and systemic risk. Any momentum is of a higher speed and intensity of propagation due to the bank-oriented nature of the country's economy. Manuscript profile

  In most executive projects, changes and rework have become one of the main risks in this area, so providing a cost management model for registering, evaluating, controlling, and managing change can play an important role in achieving project goals.In this study, field studies and questionnaires and interviews with experts, information and relevant records were collected, which resulted in finding 16 of the most effective changes in the cost of executive EC projects in the oil industry. Then, based on the management model of each of the changes presented in this research, using a hybrid method of multi-criteria decision making of hierarchical analysis (AHP) and gray relationship analysis (GRA), to provide management structure to change the cost of EC projects in the field of EC industry. This research could be useful in reducing the risk of budgeting and managing the cost of change and minimizing its impact on EC projects in the oil industry. Manuscript profile
