This research was carried out with the aim of evaluating the feasibility of using the production system in order to achieve lean production at the South Pars Gas Complex Company. The independent variable of the research is the feasibility of using the production system in time and the dependent variable to achieve lean production. The instrument for measuring this research is a questionnaire. The information necessary for testing the research hypotheses has been collected through a written questionnaire. To determine the reliability of this questionnaire, Cronbach's alpha test was used and the alpha coefficient obtained for this questionnaire was 0.92 which is acceptable and satisfactory. In this research, the questions of the questionnaire were modified and finalized by studying various texts in the field of producing at the time and pure production, and the views of the distinguished professor and the advisor professor in several stages. Therefore, the questions of the questionnaire have the necessary content validity. In order to verify the validity of the hypotheses, 150 distributed questionnaires were distributed between financial, production, warehouse and management units. The data were collected using SPSS19 software in two levels of analysis the nonparametric H-Cross-Wallis test was used for independent samples of research hypotheses. The obtained results indicate that the main hypothesis of the research is accepted, as well as the first and second special hypotheses.

The present study investigates the teaching method of solving the mathematical learning problem of high school students in Lordegan. In the present study, the statistical population is all high school students in Lordegan and sampling was done in a multi-stage cluster. Thus, the city of Lordegan was first divided geographically.

This research was conducted with the aim of finding the criteria for moral decision making of managers and is part of the researcher's doctoral dissertation. The researcher reviewed and analyzed new and related articles, as well as studied the theories of various thinkers in the field of moral decision-making and social justice, and sought the help of experts to confirm them. Findings show that the effective factors include:organizational, general, legal, professional, religious criteria, background of personality and physiological characteristics and environmental background of the person. The manager makes moral judgments based on these criteria, and the judgment is manifested in the form of a moral decision. The validity of the indicators has been confirmed by experts and it can be said with 95% confidence that it has been approved by the entire community of experts. Using a sample t-test, the confidence level in this test is 95%. The results indicate the high reliability of Questionnaire 1 and the relative reliability of Questionnaire 2. Calculating the weight of the indicators shows that religious materials had the lowest weight and individual backgrounds had the highest weight among the indicators. This diversity requires a lot of planning and action in various individual, social and organizational fields to train those who make ethical decisions in the position of management, which results in the establishment of social justice as desired by the vision of Iran in 1404.

Multi-criteria decision making is a promising framework for evaluating multidimensional, contradictory and inconsistent issues. Man makes many decisions in his daily life. These decisions range from personal and individual issues to big issues. In most decision-making issues, there are generally several goals and factors, and the decision-maker tries to choose the best option between several available options (limited or unlimited). Humans inadvertently make a large number of such decisions around the clock, some of which require more careful consideration due to the high cost of error. Decision making in complex unstable environments is often one of the most important issues. In these cases, decision makers are faced with different options that are affected by various criteria, including the internal and external environment of the organization, in which case the use of multi-criteria decision models as effective tools for decision-making are appropriate. Multi-criteria decision making is an important part of modern decision-making knowledge. These topics are widely used in various fields such as: social, economic, military, managerial, etc. In this article, we have tried to use the SAW method and also according to the opinion of experts to the specified indicators, with two components: a) ease of calculation and b) frequency of use, and assigning a weight of 0.5 to each of the indicators. In other words, fewer steps and ease of calculations with the rate of repetition and application of a particular method in various interactions and research that are of equal importance, we have been able to identify decision-making techniques by MADM method and Then categorize.

The pattern of choice,the type of reaction that a person shows in each position depends ondifferent situational,non-situational factors.

To measure the validityof the expert form,calculating the CVI,CVR indexes,the reliability was assessed usingthe measurement criteria,which included construct validity,convergent validity,divergentvalidity,hybrid reliability,Cronbach's alpha,and reliability of the index,was calculated withsmart pls software. The results showed that the instruments used are validity,reliability isnecessary. Final results suggest that rational choice theory alters customer beliefs in personalizedadvertising,helps to create a specific behavior. Therefore,considering the importance ofprivacy,the perceived impersonal cost makes the customer feel safe,trust thepersonalized advertising of Hacoupian. Because if the customer feels satisfied,secure inpersonalized advertising,he can buy the product with full confidence.
