The Impact of Observing the Principles and Rules of Correct Communication on Project Management (Case Study: Karaj City) In recent years, many efforts have been made to guide investors in proper investment and numerous models have been offered. The concepts of portfolio optimization and diversification have become tools for developing and understanding financial markets and financial decisions. In most optimization methods, the optimal answer and its accuracy are highly dependent on inputs to the extent that a more appropriate and accurate selection of input variables will be very important in stock portfolio optimization. In this research, through a regular and logical process based on the judgment method in a survey of 14 experts in the field of capital market investment and a quantitative and multivariate model of fuzzy network analysis, to assess the level of importance, ranking and refining the effective factors. Portfolio optimization was undertaken. Based on the analysis, the variables of profit volatility, return on capital, company value, market risk, stock profitability, financial structure, liquidity and survival index can be introduced as the most important factors affecting the optimization of the stock portfolio.

Identification and ranking of factors affecting stock portfolio optimization using a fuzzy network analysis approach Fuzzy Network Alireza Zamanpour1 Date of receipt: 99/07/22 Date of acceptance: 99/10/21 Majid Zanjirdar2 Majid Davoudi Nasr3 Abstract In recent years, many efforts have been made to guide investors in a way that appropriate investment takes place, and numerous models have been presented.
In this research, through a systematic and logical process relying on a judgmental method in surveying 14 experts in the field of investment in the capital market and a quantitative and multivariate fuzzy network analysis model, the level of importance, ranking, and refinement of factors affecting portfolio optimization was undertaken.
Based on the analyses performed, profit volatility, return on capital, firm value, market risk premium, stock profitability, financial structure, liquidity, and survival index can be identified as the most important factors influencing stock portfolio optimization.
In this regard, and for the first time in Iran, the present research has addressed the identification of all factors affecting stock prices and portfolio optimization, and subsequently, by utilizing the fuzzy Delphi technique, has proceeded to prioritize and determine the degree of importance of these factors.
Then, through a persuasive Delphi survey, 14 experts in the field of stock portfolio investment were selected non-randomly, and using the fuzzy network analysis pattern, the evaluation and refinement of the most effective measurement indicators of variables and the explanation of the proposed final model were carried out.
