The aim of this study was to design a model for identification and ranking of factors influencing the selection of suppliers of Iran's National Steel Industrial Group. In terms of the method, the current research is part of the descriptive research and based on its main purpose, it is an exploratory and confirmatory study, and in terms of the applied purpose. After filtering the criteria, based on the DEMATEL technique, the desired criteria affecting the evaluation and selection of suppliers will be determined and the relationship between them and the modeling of these relationships will be done. In the third step, the ANP method is used to weight the criteria. Finally, in the fourth stage, the questionnaire to determine structural modeling relationships is completed by the experts of the organization and using the data obtained from the questionnaires, the method of structural equations is used to confirm the exploratory model. The technique used in the current research was an in-depth interview-Delphi method, a statistical population of 10 knowledgeable experts on the subject of the research, and a non-probability chain sampling method. The results of the research showed that the factor of product authenticity and compliance with the standards and requested analysis of the product are in the first rank and the factors of authentic or exclusive representative of goods and after-sales services (guarantee and warranty) are in the second and third ranks, respectively.

The purpose of this research is to design a model for evaluating the policies of proportionalization of administrative system formations in Iranian National Oil Company. In this regard, the research method was a combination of qualitative and quantitative methods and tools with an applied orientation along with survey strategy and inductive approach. The qualitative part of the research included a review of the records and background of the research and conducting library studies based on the content analysis and meta-composition methods and the Delphi technique, and in the quantitative part, several techniques and tools were used, including interpretive structural modeling and structural equations, factor analysis, pairwise comparison matrix, and questionnaire tools. By carrying out the qualitative stage and refining and screening and verifying the achievements in the quantitative stage, finally 89 indicators in the form of 11 dimensions and 35 components, under the four main concepts of "policy evaluation", "proportionalization", "administrative system formations" and "macro environment" were counted and classified. In the next step, by identifying the relationship and mutual effect of the identified factors, the evaluation model of the design policy and finally the validity and reliability of the model was put into the test and approved. The issue of the optimal size of the government and the public policies related to it has been discussed and debated among political and economic experts for about three decades in the documents of the government and the ruling space of the country with different expressions such as "downsizing", "privatization" and "rationalization". Following the studies conducted in this research, with the premise that on one hand, the correct and scientific evaluation of public policies has an undeniable role in the successful implementation of policies, and on the other hand, in our country, the issue of evaluating public policies has always been like a missing link in the space that governs this territory and better management of resources in Iranian National Oil Company.

Performance management is a systematic approach that helps to improve the organization's performance through the processes of setting strategic goals, measuring, collecting, and analyzing data, reviewing performance data reports, and applying its results. An evaluation and monitoring system in the form of performance management At the macro level, which monitors the upstream documents, development plans, etc. in the form of one-year or even fewer time schedules, and provides the necessary feedback to pave the way to achieve the vision at different structural and management levels, one of the necessities which is currently the main question of the research entitled "Which is the appropriate model for managing the performance of managers?". To achieve this goal, the factors were identified using a qualitative and quantitative combined approach. In the qualitative phase of the Systematic literature method (SLR) and Delphi technique. The articles and documents selected in the systematic literature method (SLR) were evaluated in terms of quality through the CASP method. Based on the findings, 6 factors were identified as effective factors on performance. Managers were identified as external organizational factors - internal organizational factors - individual factors - input elements - performance management processes - results. Each of these factors has been used separately or in combination in various articles and research.
