With the development of urbanization, humans gradually shifted away from nature and, to the same extent and the environmental, physical and spiritual needs of man to the green space are increased. The objective of this study is to locate areas prone to developing urban forestry in the metropolis of Tabriz, from the point of view of the necessity of development and the need of citizens (not ecologically) and present developmental solutions. 14 criteria were chosen as standardized in format of Raster maps based on previous research and expert opinions. The pair comparison table comprised the criteria and the weight and importance of each criterion were calculated. After completing the multi-criteria evaluation process, the final map of the priority areas for the development of urban forestry was produced and the area and the percentage of the first, second and third priorities were calculated. Accordingly, 29.8% of the Tabriz area has the highest priority for the development of green space. In the next step, by overlaying the finalized map with the current land use map, the area and percentage of each of the first, second and third priorities located in the current land use classes were obtained. Comparison of these maps showed that 50% of the priority areas for urban forest development, were located in the existing residential areas, 39% were in vacant fields, 9.5% were in agricultural lands and gardens, and 1.5% were in the current green space. These results indicate excessive and unbalanced construction accumulation in most municipality districts of Tabriz. Therefore the general policy in these areas should be stopping new construction and prioritize changing the worn out texture of the city to green space.

Flotting paper is applied for carton as intermediate product. The amount of carton consumption is a function of many different goods production. since the goods is needed to packaging، the amount of carton consuming is increasing generally. the huge potential of consumption of this product and the lack of applied studies increase the importance of determination of effective criteria for selection of optimum location for the factory. So، 31 indexes has been determined through of library references، interview with experts and industry owners. The importance level of these criteria and sub-branches are determined with AHP and Group Decision Making. Its concluded that supply of raw materials and products and economical criteria have the highest weight value. So the branch criteria such as cost of residuals supply، sources and the supply amount of residuals have the highest preferences for selection of suitable site for flotting paper factory of agriculture residuals with weight value as 0. 094، 0. 085، 0. 069، 0. 066.

Along with the increasing public interest for recreational activities in the natural environment, the total urban green area per capita has been reduced during the recent years, resulted in an aerially-dense concentration of urban forest park users. Therefore, this study aims at conducting a suitability analysis for establishing plantation sites in a 10km buffer around the city of Sanandaj (48145 ha) in Kurdistan, western Iran. Here, a set of relevant factors including the ecology, socio-economy and tourism were studies to identify potential plantation sites. The criteria were spatially mapped following the data analysis. Questionnaires were used for evaluating each geographical map, and the Analytical Hierarchy Process (AHP) method was applied for pair wise comparison of the variables. Convenient weights were consequently assigned to each map based on the relevance of variables for establishing plantations. The final suitability map was derived by overlaying the maps of various factors in the Geographic Information System (GIS). The final map was evaluated and classified into five groups based on the finallyassigned values. The results included the regions with highest priorities which turn out to be more suitable for plantation establishment.

Regarding to various applications and adequate characteristics of HPL veneer such as beauty, mechanical strengh, un-absorption of water and vapor, as well as chemical and thermal resistances, the need to this veneer has been developed in different industries and local production make possible exchange saving. Therefore, investigating the effective criteria on optimal site-locating of HPL veneer factories has been important. For this study, the Golestan province was selected as one of talented provinces in wood industry. The effective criteria on HPL veneer site-location has been recognized and classified into "Economics", "Substructure", "Humanity" and "Materials and product" groups. The survey data has been gathered from experts, industry holders and academic connoisseurs in 2009. Weighting and ranking of measures has been conducted using flexible and practical AHP technique and the Expert Choice software. The results revealed that among 23 investigated effective criteria for site selection of HPL veneer the score of factories, the status of lateral industries with the score of 0.115, high capacity of investment absorption (0.095), number of competitors and sale markets (0.088), and assurance in supplying raw materials (0.071) were selected as priorities. By the way, the weights of materials-product, substructure, economic, and humanity criteria were derived as 0.339, 0.283, 0.268 and 0.110, respectively.

Suitable site-selection of industrial units creates proper conditions for optimum use of material and reduction of waste, and on the other hand, leads to more sell and hence high profit. The objective of this study is to determine the effective criteria in decision making of selecting the most suitable location for establishing a furniture unit. For this purpose, after preliminary investigation and interviews, 25 effective criteria were identified. The hierarchy of these criteria was designed and then the priority rates (weighting value) of obtained criteria and sub-criteria were determined using Analytical Hierarchy Process (AHP). The results showed that among 25 identified effective criteria, the five criteria as market capacity, purchasing cost of raw material, man force availability, granted facilities and man force cost have the highest priorities, respectively.
