In recent years، many different methods have been developed to simulate free surface flows coupled with moving bodies. In this paper، for simulating ship maneuver، VOF method (CICSAM) and also for coupling velocity field and pressure a fractional step method are used. To increase simulation accuracy، the mesh size should be significantly fine. Unfortunately، fine grid causes increase in simulation time. So، multigrid method was applied for solving the Poisson equation obtained in the Navier-Stokes equations، when using fractional step method. In that case، we generated some coarse grids، using agglomeration method، which needs implemention of a fully unstructured grid. To evaluate the accuracy of the algorithm، some test cases، such as two sided cavity، dam break with obstacle، and barge towing problem، as well as a comparison between V and W cycles in multigrid method have been studied. The results show that implementation of multigrid method can improve the performance of the computer code up to 100%. Moreover، W cycle behaves better than V cycle in most cases.

All Given the importance and position of internet banking and the growing trend of internet banking services in the country in recent years, now is the financial and credit institutions and banks have found a good position to maintain and develop effective strategies without the utilization of scientific and practical management Information and communication is not possible.Today,banks in order to remain competitive need to improve the quality of its internet services to the linear view of this topic is not comprehensive. In order to study integrated model web-qual and kano is used that with removal the linear hypothesis is.In the first step towards internet service quality factors based on the nation's banks web-qual model to determine the current practice of banks and provide the service expectations of customers and their vision of internet service quality mentioned has been evaluated.In the first step factors towards internet service quality the nation's banks based on web-qual model to determine the current practice of banks and provide the service expectations of customers and their vision of internet service quality mentioned has been evaluated.Considering the gap between customer expectations and current practice of banks in providing these services, services to the two categories is divided into weak and strong.In the second step of research with integrating web-qual and Kano model, service quality factors based on Kano model classified to determine which features of internet service quality determined by the model web-qual and evaluated, is the strategic importance in relation to customer satisfaction.

Due to continuous changes in organizational environment, there is no warranty for long term survival in the market. Currently, those organizations can succeed that are agile and able to rapidly respond to environmental requirements. In this research a model has been proposed for applying proper strategies for achieving long term organizational success. The proposed model is an integration of Balanced Score Card (BSC) approach, Fuzzy Quality Function Development (FQFD) and Zero-One Goal Programming (ZOGP). In fact by BSC, appropriate strategic plans can be designed and prioritized by FQFD. Then, based on multiple objectives and existing problem constraints, feasible strategic plans are identified by ZOGP. Findings imply that decision making techniques can be well utilized in designing BSC through a structured methodology; make improvement in all aspects; and have a positive influence on organization's performance in long term.
