The purpose of this paper is to present a new technique to the portfolio selection using Genetic Algorithm and Fuzzy Synthetic Evaluation. Portfolio selection is a multi-objective/criteria decisionmaking problem in financial management. The proposed approach (Genetic Algorithm and Fuzzy Synthetic Evaluation) solves the problem in two stages. In the first stage، by using genetic algorithm and fuzzy synthetic evaluation، weight of criteria will be calculated. In second stage، using Fuzzy Synthetic Evaluation، Portfolios will be prioritized. A multi objective genetic algorithm is used to determine return and risk in the efficient frontier in Tehran stock market. In this research, we have used of firms’ performance between 1396-1400 in civil engineering, construction, investment and construction materials and tools manufacturers in order to determine portfolio selection. The main advantage of proposed approach is helping an investor to find a portfolio which have Best performance، portfolio selection doesn’t rely to expert knowledge

 Recognition has been emphasized in the statement of the second step of the revolution. The purpose of this research is to identify and determine the priority of succession categories in government organizations according to the statement of the second step of the revolution. The place of research is the Iranian Statistics Center and the deputy departments of statistics and information in the management and planning organization of the provinces as the statistical system of Iran.

The purpose of this research is Identifying and ranking the categories of succession based on the statement of the second step of the Islamic revolution.

this research is mixed (quantitative-qualitative) with an inductive approach. The statistical population in the qualitative section consisted of 18 university experts who are proficient in the subject, and the quantitative section included 114 managers and experts from the Iranian Statistics Center and the deputy statistics and information departments in the management and planning organization of the provinces. In order to collect data, in the qualitative section The technique of interviewing and data coding, categories, and in the quantitative part of the questionnaire, analysis and statistical tests were used. Friedman's test was also used to prioritize the categories.

The findings show that succession planning based on the categories of the statement of the second step of the Islamic Revolution has six dimensions, which include competencies, talent acquisition, education and development of the chosen successor, sustainability and strategic alignment, succession information bank, succession selection. and the category of competencies is the most important factor in the success of the implementation of the succession system.

The aim of this study is to identify the behavioral factors affecting organizational health and select the most effective ones and design a model related to it. This model has been studied in public sector organizations and the impact of these factors on organizational health has been reported. Another goal of this paper is to draw the attention of organizational health researchers to behavioral factors.
Design / Methodology / Approach: In this study, with the help of previous research studies and the use of Delphi method, the most important behavioral factors that have a high validity were extracted. These factors were then summarized and divided into related categories using exploratory factor analysis. Also, by designing the structural equation model, the relevant model was constructed and tested.
The structural equation model obtained in this study illustrates the impact of behavioral factors on organizational health. This model also divides these factors into three categories: cultural factors, spiritual factors, and leadership style factors, and measures the impact of each factor. Researchers who want to work on the health of organizations and, above all, improve it, can take advantage of this model.
Limitations and Consequences: Due to the wide range of behavioral factors, it was not possible to study them fully in this study. Therefore, a specific time period of the articles was studied. It is also suggested that other aspects of behavioral factors be considered.
Practical Consequences: The development of participatory culture in the organization can help improve its health.
Initiative or Value of the Article: In this paper, the effect of behavioral factors on organizational health is illustrated in public sector organizations by studying extensive texts and constructing a tailored model. Since these organizations have a great impact on the lives of individuals in society, it is doubly important to pay attention to their health. This model also highlights the importance of paying attention to organizational behavior.
