It also needs to meet the demands of different user groups, including current and potential future users, in order to avoid opposition of the citizens and to support sustainable development decisions. While these requirements are well-known, conducting full surveys of user needs and preferences are tedious and costly, and the interests of different user groups may be contradictory. We therefore developed a methodology based on the prevalent Analytic Hierarchy Process (AHP), which is capable of dealing with the inconsistencies and uncertainties of users' responses by applying an Interval Analytic Hierarchy Process (IAHP) through comparing the results of passengers to reference stakeholder groups. For a case study in Mersin, a coastal city in southern Turkey with 1.7 Million inhabitants, three groups were surveyed with questionnaires: 40 users of the public transport system, 40 non-users, and 17 experts. Based on interval pairwise comparison matrices, consisting of whole judgments of all groups, the IAHP methodology could attain a consensual preference ranking for a future public transportation system between the three groups. A sensitivity analysis revealed that the factor ranking was very stable.

Due to such hazards associated with flooding as disruption of services, health impacts, famine and disease, flood protection must be taken into account in almost all development projects. Feasibility study of flood and evaluating the sensitive places prone to flood is the main step for controlling and managing the flood and utilizing it. Kaleybar Chay basin, that is located in East Azerbaijan province, is one of the areas which has experienced several floods during the last years and because of mismanagement, it has caused several life and property losses to the residents of this area. In this study, the effective factors which impact on flooding, from physical, hydrological and environmental factors were explored through executing the ANP model. Through the present research, the ETM + image of the Landsat satellite and the ANP model were used considering their abilities in analyzing the criteria and coefficient of their results with their real world. The results of the study showed that in ANP method, 20 percent of the area which is in the north areas of the basin has the high risk from flooding aspect; the results of the study were supplied for recognizing the area with high possibility of flooding in Kaleybar Chay basin and the provided maps will be used in executive organizations (such as governorate, natural resources) for logistics planning and controlling the flood.

Different techniques are commonly applied to construct deprivation indices, including multi-criteria decision methods such as the analytical hierarchy process (AHP). The multi-criteria deprivation index for the city of Quito is an index in which indicators are weighted by applying the AHP. In this research, a variation of this index is introduced that is calculated using interval AHP methodology. Both indices are compared by applying logistic generalized linear models and multilevel models, considering self-reported health as the dependent variable and deprivation and self-reported quality of life as the independent variables. The obtained results show that the multi-criteria deprivation index for the city of Quito is a meaningful measure to assess neighborhood effects on self-reported health and that the alternative deprivation index using the interval AHP methodology more thoroughly represents the local knowledge of experts and stakeholders. These differences could support decision makers in improving health planning and in tackling health inequalities in more deprived areas.
