To date customer is the main core of business activities and guarantor of performance for organizations and industries, in competitive and challenging markets. Companies with no regards to their customers will not only, not be able to make profit, but also all their resources, assets and their security will be in danger. Considering the importance of customer satisfaction and necessity of a precise survey of this very important and vital factor for long lasting organizations activities, researches of behavioral science, have made a lot of effort to create and quantify effective factors of customer satisfaction. Their main purpose was to identify both effective elements on customer satisfaction (based on their all purchases) and its consequences. But because of different cultures, ethnicities and national characteristics of people, a comprehensive model that can be used in all countries, was not practically possible. So they tried to make a model that has application in companies, organizations and industries in a specific country. As making and using such a model like this in macro and micro economics, is not deniable and will be useful and necessary for companies and organizations, so in this research it has been tried to design a model that is adaptable with an organization like Esfahan Provence Mellat Bank in order to recognize some of the elements which can affect on the identification of the rate of customer satisfaction and loyalty, also to show how these factors are related to each other and the quantify of them. So by using the method of "stratified random sampling", some branches of mellat bank in Esfahan Provence where chosen and a sample was made from the customers that where present in the bank. To analyze data, Lisrel 8.5, 15 and Eviews 5, were used. The results showed the affect of customer preference over their perceived quality. Perceived quality directly affected over customer satisfaction and perceived value. The voices of the customers were affected by these two factors. On the one hand the satisfaction factor made customers loyalty. On the other hand the customer expectations were effective on loyalty and complaints. Finally after evaluating the quantity of each of these factors and identifying the priorities for improvements (PFI) in this organization, some suggestions are made to improve the operation and efficiency of the mentioned organization, to enhance customer satisfaction and their loyalty.
