triangular fuzzy numbers

The main approach of this study is to provide solutions to managers, economists, and tax auditors. To have a clearer perspective of the transactional relationships that distress the taxpayer transaction tax also help them to choose the best strategy to improve tax revenue. In this paper the fuzzy Delphi method was used to identify the indicators affecting suspicious bank accounts. The data collected from experts familiar with the subject of research. Similarly, to rank the factors, the BMW technique was used, and the modeling method of partial least squares equations (PLS) have been used to determine the relationships between dimensions and indices. The results show the ranking of 26 sub-criteria of the research indicate that the two sub-criterions: performing operations and cash transactions less than the set ceiling and depositing cash in financial institutions and then transferring it quickly by remittance, are the first and second most important sub-criteria from below Cash operations group, respectively. The results of model also show that cash transaction factors have the most significant impact on bank account transaction tax.

The frequent violations of notaries in terms of non-compliance with tax laws and regulations provide a breeding ground for notaries and taxpayers in the field of movable and immovable property transactions, and in this regard, delay tax collection and ultimately waste government fraudulent rights. The main approach of this study is to provide solutions to managers, auditors, auditors and tax supervisors who have a clearer picture of notarial indicators and help to choose the best strategy to improve tax revenue and prevent the spread of delinquency. The fuzzy Delphi method has been used to identify the indicators affecting the lawlessness of notaries. Data were collected from experts familiar with the research topic. BMW technique was used to analyze the data. The results of ranking 29 sub-criteria of the research show that the sub-criterion of not sending information related to regulatory documents (facilitation law) for tax claims and the sub-criterion of preparing documents for definitive sale, peace, gift, power of attorney sales of vehicles without observing Article 42 of Value Added Law From the subgroup of immovable and movable documents, respectively, have occupied the highest position of importance.

In this Paper, a frame work integrated of Fuzzy Analytic Network and Goal Programming is developed to help the students to calculate the qualitative Performance of a university. To extract coefficients in a mathematical model, Fuzzy Analytic Network Process (Fuzzy-ANP) will be used. The method produced is able to consider a multi-objective nature for the problem. To do so, the other goals in designing such as the limitation of financial resources, technological possibilities, rate of development and Competitiveness of technical requirements are to be considered. Finally, the ideal model developed will contain the importance of technical requirements by the help of the methodology of Fuzzy Analytic Network Process, budget limitations, rate of technological possibilities, development and competition of a need as systematic boundaries to determine a part of technical requirement significant in designing. This framework is applied in Islamic Azad University Firouzkouh Branch.
