In this paper we aim to measure efficiency of stages of bank branches and obtain efficiency trend of stages during the time, then to estimate their efficiency in the future therefore we can be aware of stages inefficiency before occurrence and prevent them. First, a two-stage structure including deposit collection and loan giving was designed for bank branches using literature review and comments of experts. Human forces and fixed assets were considered as input variables of the first stage, deposit as mediator variable, delayed claims as interim variable, and loan amount as output variable of the second stage. Then, a dynamic network data envelopment analysis model was formulated and stages efficiency were obtained for 16 consecutive periods. Therefore, efficiency trend of stage...

Methodology: Advanced electronic identification and data storage technologies e.g. radio frequency identification (RFID), are used to identify equipment automatically and to integrate related information with equipment in various industries. The aim of this paper is to present an overview of the state-of-the-art RFID technology in asset and maintenance management. Results: In this research, author has looked into different studies and identified some clear advantages of RFID. Maintenance managers can use RFID solutions in order to accurately track movable assets, reducing manual processes through automated scanning and data entry lead to improve productivity, eliminating the costly errors associated with manual inventory, including missed or mis-categorized assets. Conclusion: This technolog...

In addition, by knowing the priority of the factors, they could carry out the resources allocation in a goal-directed way. By seeking the opinions of the senior managers and advisors Bahman Diesel Industrial Group, 34 critical success factors whichhad been already noted in the precedent studies were identified. However , due to the difference in the type of organizations and lack of priority, there was no justification in using the already identified raw critical success factors. Therefore; by considering the prioritization of the managers in different sectors, as the main customers of the products yield through enterprise resource planning, the critical success factors were classified, prioritizes and named by benefiting from experts view with reg...

For this purpose, quantitative approach and survey method were used. Three groups of stakeholders, including employees, managers and clients were organized. The total number of samples included 200 employees, 35 managers and 30 clients. Employees were selected by random sampling, clients by available sampling, and managers by census method. Data were collected through questionnaires consisting of seven dimensions based on Ward and Elvin model. Content validity of the questionnaire was used to validate the questionnaire. On the other hand, Cronbach's alpha was applied for reliability of the questionnaire which was appropriate (0.92). In addition, one-sample t-test and Friedman test were used to analyze the data. The findings showed that the barriers to organizational processes, organizational outcomes, and internal context of the o...

Then, with the use of linear programming technique, decrease the total expected cost of conveyance. In the next stage, by using the Hungarian allocation technique, for each line of assembly shop, lifter and the operator was allocated and in the next stage classifying the raw materials transportation paths from warehouses to assembly shop to determination the best transportation path by use of ‘technique for order preference by similarity to ideal solution’ (TOPSIS). Finally, usage of production distribution model to optimum distribution of productions in Sanaye Felezi Iran Co. © 2015 Elixir All rights reserved. Elixi...

Statistical society included opinions of 254 official personnel of organization. Gathered data through inquiries analyzed by "SPSS18" software. The study results show that Esfahan municipality personnel's organizational commitment and job satisfaction remarkably affected by emotional intelligence. Besides, there is a positive and significant relationship between emotional intelligence and job satisfaction. Moreover, the relationship between emotional intelligence and organizational commitment approved. Data analyzes declare that there is significant relationship between emotional intelligence and personnel's emotional commitment, continued commitment and normative commitment. On the other hand, emotional intelligence has a positive significant relationship with satisfaction of job, satisfacti...

However, it should be considered the effectiveness of the Internet, in conjunction with the organizations to achieve long and short term goals, identifying strategic stakeholders (including customers, managers, and owners) and their wishes to be granted. The attractiveness of the site plays an important role in users’ durability and enhances their motivation for exploring and foraging; and usability of the website is a necessary condition for its survival. In this regard, the main purpose of this study was to determine the effect of the content of the website and electronic trust on the effectiveness of emarketing in the food industry. In this study, the model of Rahimnia and Hassan Zadeh (2013) which includes the variables of informational website, Web design, e-trust and effectiveness of e-marketing was used. The study in terms of purpose is applied and in the t...

There are few unsupervised approaches for brain tumor segmentation. In this paper, a new unsupervised approach based on graph coloring for brain tumor segmentation is introduced. In this study, a graph coloring approach is used for brain tumor segmentation. For this aim, each pixel of brain image assumed as a node of graph and difference between brightness of a couple of pixels considered as edge. This method was applied on T1-enhanced magnetic resonance images of low-grade and high-grade patients. Since a rigid graph was needed for graph coloring, edges must be divided into existing or nonexisting edge using a threshold. The value of this threshold has affected the accuracy of image segmentation, so the choice of the optimal threshold was important. The optimal value for this threshold was 0.42 of maximum value of difference of brightness between pixels that caused the 83.62% of correlation accuracy. The results showed that graph coloring approach can be a reliable unsupervised approach for brain tumor segmentation. This approach, as an unsupervised approach, shows better accuracy in comparison with neural networks and neuro-fuzzy networks. However, as a limitation, the accuracy of this approach is dependent on the threshold of edges.
