This study tries to review the projects of the National Iranian Oil Company based on social responsibility indicators, in accordance with the ISO26000 standard. Therefore, this study has considered 990 completed or ongoing projects of this company in Khuzestan province. These are graded and weighted according to ISO26000 according to the opinion of experts and people affected by them, then classified, compared and graded using the combined method of Shannon entropy and TOPSIS. The results show that the projects donat scored well in achieving SDGs based on ISO26000, and therefore, the prevailing view of social responsibility in the company is still based on charitable activities. However, the project of controlling dust (natural resources), construction of entrepreneurship centers and educational programs have gained the highest score

The aim of purchasing portfolio is commodity classification to determine the suitable purchasing strategy. In this research, we propose a new method for the classification of commodities with the extension of purchasing portfolio approaches. Indeed, the purpose of this research is to determine the appropriate purchasing strategy for commodities with the consideration of purchasing portfolio. Furthermore, first, by reviewing the literature and surveying the specialists and databases, the dimensions of profit impact, market complexity, and the balance of supplier and buyer power were considered and appropriate criteria for classifying commodities and services were determined. After determining the number of dimensions, the weight of the criteria in each dimension was calculated using the best-worst method. Then, using the TOPSIS method, the score of commodities was obtained in each dimension and the position of the commodities and services was determined on a matrix. To determine the most suitable strategy by considering commodity position based on three defined dimensions, at first, the appropriate strategies were collected by reviewing the research literature, and then, the most appropriate strategy for each category of commodities was determined. Finally, the proposed method was implemented for the commodities of a company, and the results were presented.

Considering the balanced and comprehensive development of the provinces of the country, reducing heterogeneity and inequality, policy making and planning to achieve goals that vary according to the structural characteristics, facilities and constraints of each province, requires the study and recognition of the characteristics of each province according to its location in the whole system of the country. In this research, different provinces of the country have been ranked by the TOPSIS and SAW methods in the fileds of "social, cultural and political", "economic and production" and "infrastructure and technical". The results of the ranking of the provinces, indicate that the provinces have different positions. For example, the provinces of Semnan, Ilam and South Khorasan ranked first to third in the fileds of social, cultural and political issues, but the provinces of Fars, Mazandaran and Khorasan Razavi were top ranked in the fileds of economy and production, and the provinces of Isfahan, Mazandaran and Qom ranked first to third in terms of infrastructure and technical indicators.

Decision making about the selection of shares for buying and selling for more return acquisition is the most important subject for investors in stock exchange market. Many of investors buy shares based on market gossips and informal news.As each of the existing models such as technical method, fundamental method, Markowitz model, sharp model and arbitrage model has it's own problem in use, this research gives a model for choosing portfolio regarding effective indices on investors decision making by composing the TOPSIS and GAHP techniques. A questionnaire was prepared by using Delphi method and was distributed to 30 persons of the experts of stock exchange market to identify significant indices for investors. Economical indices for choosing the industry including selling growth, profit margin growth, average return, currency rate, basic metals price volatility, industrial competitive advantages, economical growth and recession and economical indices for share selection contain EPS, DPS, P/E, share price, share return, operating profit ratio, corporation management, corporation size, capital volume and technology were achieved.Necessary information and relevant amounts to each of indices were gathered from archive unit and internet site of securities and exchange organization and financial statement of companies. Then by TOPSIS technique and weighting by Shannon entropy and group AHP techniques in changing qualitative to quantitative indices (which is one of the most advantages of this method) decision matrix was composed and the priority of industry and share identified. Five superior industries were Banking, Credit and other money institutes, Investment brokers, Foods and Beverages products except candy and sugar, coal extraction and Other Nonmetallic mineral products.

The researches show that the implementation of Just-In-Time isnt unique in all situations. The implementation of this system may be differed in different companies, regions or countries and the some components that are needed to situations may be isnt vital in other situations. The purpose of this study is to identify elements and components that are critical to lust-In-Time success. This articles goal is proposing a method for this notification in lust-In-Time implementation by using antropy, TOPSIS and Pareto techniques. In this method we use TOPSIS and Pareto techniques for setting a priority and then selection of component and use entropy method for giving coefficient to TOPSIS matrix. At the end, in this case 5 components from 11 possible components in this system to implement in these companies have extracted.
