Problem Statement: Researches of quality of life are concentrated mainly on the urban nature in the recent years and the urban quality of life gained many attentions in empirical studies. The concept of urban quality of life is a multi-dimensional and complex issue. So, needless to say that this concept can be used in planning when there is an appropriate and reliable framework for measuring. Approach: The present study tried to create a framework on the base of Analytic Hierarchy Process (AHP) for objective measuring of urban quality of life and then it would be applied for a comparative study of two northern cities of Iran. Results: The results showed that using analytic hierarchy process model creates opportunity to involving the different groups' views of urban users with respect to their duties and functions in the stage of criteria weighting. Conclusion: This process not only provided an appropriate bed for objective measuring of urban quality of life but it facilitated the participation of urban authorities in the process of measuring and analyzing the urban quality. Also one of the advantages of the model was its high level of clarity and simplicity which could be perceived by all urban decision makers.

INTRUDUCTIONResearchers from a variety of disciplines have studied Quality Of Life (QOL) since the 1930s [53] . They tried to identify the components of QOL and compared various geographical areas such as cities, states and nations by means of QOL indices that they developed [2,3,25,48,47] . In addition to the researchers, international organizations such as UNDP [51] developed its own measures for QOL. The desire to improve the quality of life in a particular place or for a particular person or group is an important focus of attention for planners [28] . An important reason for such an interest in QOL lies in the question of effective allocation of scarce resources [32] . In fact improvement of life quality in each society is one of the important aims of public policies. In recent years studies of life quality have mainly concentrated on the urban nature and urban quality of life gained much attention among the researchers. Clearly the increase of urban population and the increasing tendency for living in the city is one of the main incentives to expand an independent movement on life quality researches.The urban QOL concept gains more importance when it is considered that the world population is expected to reach somewhere between 7.6-9.4 billion [22] and the urban population is expected to reach 50% [47] in the beginning of the next century. The multi-dimensional character and evolutional nature of quality of life led to different interpretations which made the investigation difficult. So the recent research on the quality of life emphasis on the quality of measuring this concept in the cities. Clark and Kahn [7] used a two-stage hedonic approach to estimate willingness to pay fo...
