This research is descriptive and analytical in terms of its purpose, which has used the combined method of DEMATEL and Interpretive Structural Modeling (ISM) and MICMAC method to analyze the research data and discover the cause and effect of the factors. With the help of industry experts, 16 effective factors of total quality management were identified by snowball sampling method.

Nowadays, the environment has become a vital issue for all human beings, both as a customer and as a producer. In today's society, electrical are widely used. Therefore, it is necessary to pay attention to methods to reduce energy consumption in such devices. One of these methods is to use energy labels for electrical devices. So it controls and saves energy. This raises the question of whether related factors related to willingness to pay, such as environmental attitudes, health concerns, environmental concerns, mental norms, past consumer experiences, brands of environmental companies, perceived effectiveness and control of perceived consumer behavior. Can the buyer have a positive effect on the consumer's purchasing attitude? The present study is applied in terms of purpose and descriptive and correlational in terms of method. Library studies and standard questionnaire distribution have been used to collect data. The sampling method is random. Using Jersey and Morgan table, the sample size was estimated to be 384 people. SPSS 22 software was used to assess the validity of the questionnaire. The results showed that there is no significant relationship between the two variables of environmental attitude and customer attitude towards products. Also, there is no significant relationship between the two variables of attention to health and customer attitudes toward products. Therefore, the hypotheses of the effect of environmental attitude and attention to health on the customer's attitude towards green products were rejected and twelve other hypotheses were confirmed.

Standard and standardization is one of the human approaches and tools that are used to improve the product, both goods and services and today, one of the most important elements in t,he development of business is the communication between individuals, groups, companies and societies, and laying the foundation for economic growth. Regardless of the type of extensive function that is considered in the standard, its checking it with Islamic principles and its conceptual and practical reconstruction is necessary for the Islamic society. The current research, which was conducted with a qualitative research method of the type of implication research, by examining a collection of narrations and relying on jurisprudential arguments, With the aim of comparing the conventional and religious view of the standard issue, has tried to estimate and confirm the potential and actual capacities of the development of the standard category based on Islamic teachings by identifying various examples and a wider range of aspects. count its social. The findings of the present research show that from the

The main purpose of this research is to investigate the relationship between the consumer's qualitative evaluation of the product, trust and willingness to buy again in Hamadan students' e-commerce. The research method is based on the practical objective and in terms of the descriptive survey method, it is a correlation type. In order to measure this research, the standard questionnaire of Kim and Sullivan (2018) with a seven-level spectrum was used. The statistical population of the research is the students who have made online purchases more than once in Iran, which considering the limitedness of the population and using Morgan's table, 384 people were chosen to respond and the sampling method is simple random.

One of the important issues in the field of decision-making of industrial organizations is determining the optimal time to use equipment. Because premature replacement, additional costs for the organization and late replacement will increase maintenance and repair costs. As a result, equipment management can be shown by using the useful life of the equipment. Now, calculating and identifying the life cycle is essential to determine the optimal life of the equipment. In the current research, the cost of the life cycle for the melting furnace of machines is implemented, the first article is to determine the life cycle cost model and the collection and cost of the costs, and then using the relations of engineering economy, the duration of use of this equipment with the help of the life cycle cost and point to be used. It comes to the head. Finally, after calculations and investigation, it was determined that the company's melting furnace should be removed after 10 years of use. In fact, the use of the life cycle, in addition to determining the time of equipment replacement, helps the managers of industrial organizations in making decisions.
