Nowadays, energy management is highly regarded throughout the world. High energy consumption leads to high costs for consumers in the long term and at the national level. In this study by modified consumption patterns and presenting a proposed plan, it has been tried to optimize electrical energy consumption in hospitals.The proposed model is a goal programming model. Objective functions consist of minimization of peak energy consumption and minimization of electricity costs. Some constraints such as daily energy requirements and user preferences have been modeled using mixed integer programming. Regarding objective functions, three different scenarios have been considered.The developed model can be easily performed in a hospital unit. The combined scenario that has been considered both objectives simultaneously is the best.The proposed model is a practical one for intelligent management of electrical consumption. Thus, performing the model in hospitals is recommended.

The issue of elite emigration from our country to the developed countries as a social phenomenon is the result of economic, cultural, social and political factors in Iranian society. This phenomenon had harmful impacts on the economic, political and social growth and development processes. Elite emigration has been neglected over the years. Statistics reports show that by each emigration of an elite person from Iran, $ 5 million of the Iran's capital will be lost. Therefore, it is essential to find the motivations of elite emigration and explore the strategies and practical solutions for the elite emigration. Thus, the aim of this study is to analyze a variety of scenarios and their impacts on the rate of emigration. Due to the complexity of the problem and causal relations, feedbacks and causal loops, system dynamics approach was used in this study. The model performed in Vensim software. Results show that the policy of reducing tension in foreign relations has not a significant impact on the rate of elite emigration. In addition, according to the results of proposed policies, it is recommended to the government and policy makers to respect the meritocracy in the scientific, management job appointments as well as improve the job security and employment status of elites.

The present research studies the strategic situation of teachers training in Kohgiluyeh and Boyer Ahmad province using SWOT analysis. The research method is descriptive-field ones. The population of the study included all teachers of primary schools in Kohgiluyeh and Boyer Ahmad province as being 5570 teachers in the educational year 2014-2015. 360 teachers were selected through multistep cluster random sampling based on Cochrane formula. SWOT analysis researcher-made questionnaire was distributed among them. Content validity was used to determine the validity of the questionnaire and Cronbach alpha to determine the reliability (α=0.91). the data was analyzed through descriptive statistics, one-sample t-test, Freedman statistc test, external and internal factors evaluation matrix. The results showed that high levels of teacher's knowledge (strength), the lack of necessary financial resources to successfully do the plans (weakness), the existence of economical advocates and subsides to education by the state (opportunities), and teacher's personal and economic problems (threats) are the most important priorities of SWOT analysis. The results also showed that primary teachers training in Kohkiloye_Boyer Ahmad province places in WO situation.

Supplier selection is a vital process in which the vender tries to improve its relations with the chosen suppliers. In this procedure, by considering all alternatives and criteria evaluation, suppliers are selected. One of the methods used to evaluate and choose suppliers is Data Envelopment Analysis (DEA). This paper proposes a model to evaluate suppliers with DEA. Sustainability criteria, which includes measures of three aspects, social, economic and environmental, are considered and three approaches, aggressive, benevolent and conservative of DEA, for considering all policies of organizations is utilized. In this research, a case study is conducted at a stone factory. Data’s of 19 quarries as suppliers in this research, is collected and top 10 suppliers are chosen and suggested to the factory. This model is solved with GAMS and finally, sensitivity analysis on the top ranked suppliers, displays importance of the criteria to help other suppliers to improve their performance.

Today, which is more important than the past for organizations, is their ability to cope with environmental changes. Organizations’ leaders create individual initiative spatial; that can drive organization to adapt to changes and consequently supply the organizational goals. Moreover, managers knowledge sharing assists the organization in coordination to level strategies and adaptable ability. The purpose of this study is to investigate the effect of innovation leadership and knowledge sharing to organizational strategies on environmental changes. The population of this study was the subsidiary companies of Tavanir (The Management, Production, Transmission and Electricity Distribution Company of Iran) and based on notifications in this company, totally 86 companies included state and regional electrical companies, has been selected for analysis. The minimum and maximum necessary sample gained by Cochran formula was 58 to 70. Data collection was based on a questionnaire by 25 questions that finally 68 questionnaires were returned. Descriptive and analytical Square Equation Modeling (SEM) analysis was performed by SPSS & SmartPLS Software. Then, the analytical results show which, of the seven hypotheses, four hypotheses are approved that indicates that in turbulence environment, the knowledge sharing and innovative leadership, has positive and direct effect on organizational performance. Also, these variables can increase the strategic coordination of organization by external environment, but the strategic fit does not effect on organizational performance that could be due to the failure of strategic planning review.

The strategic thinking is considered as the core of creating a competitive advantage in an environment that its feature is complexity of constant change. Nowadays strategic thinking is known as a trump card in various field of economic and social object.
They have emphasized more on this point that senior managers must be equipped with an important tool which is called strategic thinking.
This research investigates the role of strategic thinking in structural complexity, and effects of these factors to each others. Causative research has been done by means of questions including 50 questions and sample size of 327 in Hepco Company of Arak. Analysis of information has been carried out by multivariate regression equation and Structural equation. Common aspect of these two analyses can be considered as the main findings of this research.
Findings showed that systematic approach, hypothetic-centered have had significant effect on vertical and horizontal separation. But components of intellectual opportunism and thinking over the time have not had significant effect on vertical and horizontal complexity.
