The construction industry is one of the broad, decentralized and highly indigenous industries of any country. In many countries, it is considered an indicator for growth and development or economic stagnation. This industry in Iran is currently experiencing a lot of inefficiencies, one of the main reasons for which is the lack of growth in the technical field. The use of traditional methods is known as one of the main factors inhibiting productivity in the construction industry in Iran, because most conventional techniques and their nature led to time delays and waste of resources. Therefore, it is necessary to use new technologies in this vital industry. Building Information Modeling (BIM) technology in construction projects is essential, including the benefits of using BIM, improving coordination and communication, increasing productivity, reducing errors, improving construction quality, etc. Therefore, in this research, the benefits of using this useful technology in the life cycle of a construction project have been investigated .

 Participatory economics is an economic idea based on the view that most people tend to borrow consumer goods instead of buying and owning them. This will lead to increase employment, economic efficiency, access to valuable assets, and increase social relationships. Aims’paper is to promote participatory housing in the territory as a solution to strengthen intergenerational solidarity, and more broadly to participate in the construction of a more resilient territory. Also, another purpose of article is to develop and increase people's awareness about participatory housing.
  

The present research is based on the purpose of Applied Research, and according to the nature of subject and objectives of the research and executive facilities, we have used the field and survey method. We also used the questionnaire method of data collection, because the questionnaire is the main instrument for collecting data in survey research. The designed questionnaire has 31 questions and to answer the questions, number 1 is completely agreeable and number 5 is completely disagreeable. The questions about each variable to measure that variable for the desire to participatory housing.The technique of sampling and determination of sample size have crucial role in survey-based research problems in applied statistics. Similarly, if the sample size is inappropriate it may lead to erroneous conclusions. One of the equations for calculating the required Sample sizes based on the size of the Cohen d effect provided by Mead. In this article, the sample saize considered to 65 people by Mead equation. Accordingly, the statistical sample of the study consisted of 65 residents of Yazd by random sampling method, and aiming to measure the willingness of individuals to participatory economics in the use of participatory housing. The main variable of the research includes the tendency to participatory housing, and Variables affecting it include economic benefits, sustainability, entertainment (pleasure), social relationships, Internet network effects, and attitudes. Finally, the effect of variables was examined using path analysis. According to information that we have received from the review of experimental research and the researcher’s observations, the research hypotheses are:-Economic benefits have a significant effect on the attitudes of consumers and suppliers in the use of participatory housing.
- Sustainability has a significant effect on the attitudes of consumers and suppliers in the use of participatory housing.
- Entertainment (pleasure and happiness) has a significant effect on the attitudes of consumers and suppliers in the use of participatory housing.
- Social relationships have a significant effect on the attitudes of consumers and suppliers in the use of participatory housing.
- Internet networks have a significant effect on the attitude of consumers and suppliers in the use of shared housing.
- Consumer's and supplier's attitudes have a significant effect on their willingness to use participatory housing.
- Gender has a significant effect on the attitudes of consumers and suppliers to use participatory housing.
- Gender has a significant effect on the willingness of consumers and suppliers to use participatory housing.
  

This studies aimed at investigating the effective factors on the tendency to participatory economics in Participatory housing. In this regard, the present study examined the relationships between attitude-related subscales including economic benefits, environmental sustainability, entertainment (pleasure and happiness), social relationships and the development of Internet networks towards the tendency to use participatory housing. In addition, the relationship between the attitude towards participatory settlements and the tendency to participatory housing was considered.
The Outcome of path analysis showed that the variable of happiness had the greatest effect on behavioral tendency and then the variables of Internet networks, attitude, social relationships and gender were recognized as effective variables. Among all the influential variables, only the social relations variable had the opposite effect.

Variables had related to attitudes toward participatory housing, but the entertainment (pleasure and happiness) of use participatory housing and the development of Internet networks have a positive effect on attitudes. The charm and curiosity gained from this kind of lifestyle and the  relationship network created through the development of Internet networks, lead to more opportunities for individuals. In many ways, relationship networking, leading to creation and development of business opportunities. Because, that creates more options of accommodation and diversity in choosing the place and facing different prices and a better attitude towards the participatory housing. Also, the type of attitude has affects on desire of individuals to use participatory housing. Then, the effect of gender was examined on the variables of attitude and willingness of people to use of participatory housing. Findings showed that the gender of respondents had no effect on their attitude. And only, the gender had affect on stability. As a result, people have a better attitude and a greater desire for participatory housing due to lack of social relationships and access to more pleasant times.

One of the best approaches to creative management is the Amabel creativity model, which has weaknesses that prompted researchers to use a standard questionnaire to assess the atmosphere of Amabel's organizational creativity and measure organizational creativity to provide a new model for developing the Amabel organizational creativity model.

The research is descriptive and structural equation modeling. Its statistical population was completed by 392 people in all companies under the industry and 78 questionnaires. Exploratory and confirmatory factor analysis and structural equation modeling using SPSS and Smart PLS software were used to design the model. Descriptive methods, as well as the weighted mean and Friedman test, were used to analyze the data obtained from the creativity test.

The findings are presented in four topics. The first three topics are related to the development of the organizational creativity model of Amabile. The fourth chapter assesses organizational creativity at the level of the industry under study, which evaluates the results of organizational creativity at a medium to near level.

Originality/Value:

 Among the six factors of organizational creativity, the status of the two factors of unit productivity and single/working group support was evaluated better and higher than the other factors and the status of the two factors of creativity and organizational support was slightly weaker than other factors.

The countrys electricity industry, which is responsible for supplying, producing, transmitting and distributing electricity in the country, needs to pay attention to creative approaches. This can be seen in the review of jobs related to this industry, as about fifty percent of jobs in this industry require creativity skills, and not paying attention to strategies and targeted measures to promote organizational creativity can challenge the industry in the near future. Face basic. In this study, by considering the main and secondary questions regarding the selection of appropriate organizational creativity strategy in the electricity industry, by collecting the opinions of electricity industry experts, the factors and conditions affecting organizational creativity were determined and using content analysis technique. Interpretive The results of the interviews with the experts were analyzed. Using the three-step approach of data-driven theory, the phenomenon of non-creativity was studied in an inductive manner at each level, and the relationships between the phenomenon, causal conditions, mediating conditions, strategy and strategy and the consequences of each strategy were obtained. At the individual level, non-creative phenomena were categorized into 5 categories and 58 codes. At the team or unit level this phenomenon was categorized into 5 categories and 36 codes, at the organization level it was categorized into 5 categories and 42 codes and at industry level this phenomenon was categorized into 5 categories and 40 codes. This model can be used in other areas of government.

Today, organizations are under tremendous pressure to continuously enhance their capabilities to create value for customers and improve the effectiveness of equipment. Without the proper equipment organization will face major challenges in competition and customer satisfaction. Inappropriate performance of equipment is a phenomenon that any manufacturing organization faces with it. The what strategy is selected against this phenomenon, depends on several factors. This issue becomes more important when the production line is continuous. In electricity company providers because of supplying strategic product issue is more complex. In this study, tried to determine the factors affecting the conditions in relation inappropriate performance of equipment to define this phenomenon. Therefor, using a three-stage approach of Grounded theory, with inductive method to study the phenomenon of improper performance of equipment has been studied and with gathering the experts opinion this industry and analyzing relevant data in five categories and 24 subcategories and 90 characteristic this phenomenon has been described and then how to choose appropriate strategies for different conditions explained.

At the present time, it is impossible to imagine manufacturing organizations without running maintenance systems. Maintenance is a system that supports the core processes. Therefore, a maintenance system is essential for manufacturing organizations in order to maintain competitiveness. As yet many studies have been done on maintenance systems but there is almost no study comprehensively examining various aspects of the system. In this study, defining the attributes of maintenance phenomenon, dimensions and components of maintenance system are clarified. By the use of meta-synthesis approach, previous studies are analyzed and maintenance phenomenon is categorized in five dimensions, 31 sub-dimensions, and 98 components. Finally, the effect of the specified components in 209 previous studies has been determined using Shannon entropy method. And, it has been shown that what factors or codes have received the most emphasis in each theme.

The current web evaluation models are mainly based on the technical evaluation of the site and its appearance and usability from user's perspective. In other words, the site is evaluated as an independent entity from the underlying organization that it represents. The focus of this study is on evaluation of organization's websites based on the quality management concepts. In this way, the measured performance indicators will be used to find the deficiencies of the websites and recommend corrections. For evaluating the organization’s success in its website function, the concept of quality management is used and since evaluation and improvement are the center of attention in this model, the model is called Ev-Imp, which Ev stands for evaluation and Imp stands for improvement. Model includes four main components consist of objectives, processes, criteria and feedback. With the use of feedback tools such as quantitative and qualitative questionnaire for groups of stakeholders and service providers ,the website’s weaknesses and strengths would be identified and with analyzing the website’s weaknesses required improvement would be determined and corrective action would be done.

The previous studies about the maintenance systems were dealt with defining the evaluation criteria, grouping them, and using different techniques for evaluating. The main problem is that maintenance subsystems and the relationship between and within them in order to a reliable evaluation have never been identified before.
The contribution of this study is realizing the four maintenance subsystems consisting service and maintenance, inspection, chronic failure, and severe failure and investigating the communication between them that has never been done in previous studies. On the other hand, in each subsystem the relationship between causal conditions, phenomenon, mediator condition, strategies and consequences that had been neglected in previous studies are discussed for the very first time. Causal conditions, that cause each of four subsystems, are identified. Then phenomenon and mediator conditions are presented and the strategy that should be made based on the characteristic of phenomenon and mediator condition is determined as well. Since making a strategy can lead to a consequence, the consequences according to different strategies are identified that has never been done in previous studies. At last, the relations between these parts are presented in narratives.

This paper evaluates the behavior of a manager in a period of time as a sample and gives detailed results and analysis in relation with organizational goals. It uses computer software to record daily activities with some details. In order to improve a manager’s behavior in relation with organizational goals TMIM was designed. TMIM measures and evaluates the time spent by the managers to improve the way of allocating their time to the organizational expectations. This model considers the time spent by managers to organizational goals and in the meantime considers the attention they pay to continuous improvement as a strong tool of productivity as well. In this model «the main activities and key processes of the organization»، «the way of communications» and، «departments and personnel» are determined first. Then، the time a manager spends to handle the organizational processes in relation with departments and personnel through a compatible communication is measured. Finally، spent times are analyzed and time management solutions are presented. The designed model was performed in an electric service providing company through figuring out the characteristics of the managerial behavior by recording and analyzing four years experiences. Before performing this model، time allocation by the managing director was not compatible with the organization''s missions and goals. After performing TMIM; analyzing results; and giving feedback، new time allocation led to obvious improvements and managerial effectiveness as a result of the manager''s performances.
