Customer satisfaction represents a modern approach for quality in enterprises and organizations and serves the development of a truly customer-focused management and culture. Measuring customer satisfaction offers an immediate, meaningful and objective feedback about clients' preferences and expectations. In this way, company's performance may be evaluated in relation to a set of satisfaction dimensions that indicate the strong and the weak points of a organization. In this research and for the first time in Iran; Multicriteria satisfaction analysis is offered for measuring and analysis of customer satisfaction in export development bank of Iran (EDBI). The integrated methodology evaluates the satisfaction level of a set of customers based on their values and expressed preferences. This research has been performed in according to request of Customer Affairs and Branch Coordination Department in EDBI that by solution of several linear programming model (with respect to Hierarchical structure of customers' satisfaction dimensions), average satisfaction level and importance (weight) of each dimension will be achieved and finally by development of a set of quantitative indices and perceptual maps makes possible the provision of an effective support for the satisfaction evaluation problem.

This study analyzes wind energy potentials of Zanjan province which located in northwest of Iran. Renewable energy plans are not fully environmentally safe and different renewable energy plans have different environmental impacts. Therefore, site selection is an important issue in the wind turbine installation and therefore, selecting an appropriate wind turbine site requires consideration of multiple alternative solution and evaluation criteria because of the system complexities.  In this paper, using AHP and fuzzy TOPSIS techniques in conjunction with GIS, wind turbine potentials of the study area are evaluated. Criteria weights are obtained from pairwise comparison of identified criteria and after fuzzification of both criteria weights and criteria map layers using triangular fuzzy numbers, fuzzy TOPSIS technique is utilized to integrate and rank more suitable alternatives for the wind turbine installation. The results shows the ability of multi-criteria methods to evaluate suitable sites in geographic areas on one side and good potentials sites of Zanjan province to establish new energy plans on the other.
