The existence of educational use is accounted as an index element through the urban areas (Zarabi et al., 2009:46). Nowadays, with regards to population invasion to big cities and due to construction of whole urban lands and insufficient positioning of municipal services especially in educational centers, several problems have been caused in the field of youth and students services. So, optimal positioning of educational centers is necessary (Mikaeili; 2009: 6).     According to the statistics of Fars educational organization within the year 1388, across the city of Kazeroun, there are only 31 schools with 4611 students. Now, the educational space of guidance schools is about 58005 m2 which is accounted as less than as 1percent.. This level of area in comparison with its optimum situation, 99117m2, shows 44112 m2 shortages (Consulting Engineers of Naghshe Mohit, 2009:53). So, the necessity of making new schools across the city of Kazeroun and their proper positioning is felt.    <strong>2- Methodology</strong> The descriptive- analytical method has been used in this research. All data have been collected by field observations, study of comprehensive models of Kazeroun city and educational organization of this city. Then, proper locations for constructing guidance schools were preceded using the GIS software and after information entry, data management and analysis them. <strong>3- Discussion</strong> In this research seven following data layers have been used in order to proper positioning of guidance schools of Kazeroun city; involving proximity to communication network, proximity to urban green space, proximity to residential centers, proximity to cultural centers, distance from available guidance schools, locating across the proper land use, locating on proper slope. Table 1 shows the Rating to information layers according to distance.     <strong>Table1.

For instance, sterile use is higher rated and commercial use is lower rated according to their lower and higher economical values, respectively. In the following, the optimal locations maps in order to build new guidance schools across the city of Kazeroun could be seen.           As shown in the map1, major proposed locations for guidance schools construction are located at suburbs; because of suburbs in comparison with other places have higher grants. Considering with the shortage of these places, the construction of guidance schools in proposed areas not only will affect the development of whole city of Kazeroun but also can help citizens access to educational services.   <strong>4- Conclusion</strong>  There are several causes in positioning of educational centers (guidance schools), which their different aspect analysis are not been possible by traditional methods. Therefore, geographic information system is necessary for a great deal of information analysis. Also, analytical hierarchy process (AHP) and geographic information system (GIS) have a high efficiency in the field of guidance schools positioning. This efficiency is not related to the comparison and estimation different locations and optimal place selection according to mentioned criteria. After revealing the problems of guidance schools positioning of Kazeroun using GIS, , analytical hierarchy process (AHP) and index overlap model have been used in order to position new guidance school buildings. Ultimately lands which are located in the city limits of the legal and privacy of Kazeroun were leveled and six locations were investigated for new schools. Then, using AHP, these six locations were preceded and best place was detected.   امروزه فضاهای آموزشی یکی از مهمترین کاربری‌ها در شهرها است و سطوح قابل توجهی از فضای شهر را به خود اختصاص می‌دهد. با توجه به فعالیت‌هایی که در این فضاها صورت می‌گیرد نسبت به سایر کاربری‌های خدمات شهری از اهمیت قابل توجهی برخوردار است. شهر کازرون که در این مقاله مورد بررسی قرار گرفت کمبود مدارس راهنمائی و توزیع ناعادلانه آن به شدت احساس می­شود. هدف از انجام این تحقیق تعیین مکانهای مناسب و بعد از آن بهترین مکان برای احداث مدارس راهنمائی جدید در شهر کازرون است. روش پژوهش به کار گرفته شده در این مقاله، روش توصیفی- تحلیلی است. برای این منظور از سامانه اطلاعات جغرافیایی ) (GIS ، مدل همپوشانی شاخص‌ها( IO ) و فرآیند تحلیل سلسله مراتبی ( AHP ) استفاده شده است. در این مقاله با بررسی و ارزیابی معیارهای موردنیاز در مکان یابی مدارس راهنمائی و به کارگیری نقشه‌های 1:2000 شهر کازرون، ابتدا با توجه به معیارهای لازم برای مدل­سازی مکانهای مناسب مدارس، نقشه‌های معیار تهیه و طبقه بندی مجدد ( Reclassification ) روی آنها انجام گرفت و بعد از آن به روش وزن دهی مقایسه‌ زوجی‌‌، که بخشی‌ از روش‌ AHP است‌، به هر یک از معیارها وزنی داده شد و با استفاده از مدل تهیه شده، لایه‌های اطلاعاتی به روش همپوشانی شاخص تلفیق و مناطق مناسب مشخص شد.در انتها نیز با استفاده از فرآیند سلسله مراتبی( AHP )، 6 مکان برای احداث مدارس راهنمائی پیشنهاد گردید. همچنین بین این 6 مکان پیشنهادی، اولویت بندی انجام گرفت. https://gep.ui.ac.ir/article_18534_0061b9412e8ee9ab56fd7d266cfcb23d.pdf
