چکیده
زمینه و هدف: گسترش بی‌رویه رشد شهرها در سال‌های اخیر موجب افزایش تولید انواع مواد زائد جامد در مناطق شهری شده است. اگرچه دفن آخرین گزینه در مدیریت پسماندهای جامد شهری است، اما در کشورهای در حال توسعه یک روش معمول مدیریت پسماندهای جامد شهری می‌باشد. هدف از این پژوهش مکان‌یابی دقیق لندفیل شهری در شهرستان نایین با استفاده از تلفیق روش‌های فازی و بولین است.
مواد و روش‌ها: در این مطالعه به‌منظور استانداردسازی و تعیین وزن معیارها و زیرمعیار از مدل AHP استفاده گردید. نوآوری این پژوهش تلفیق نتایج حاصل از منطق فازی و بولین است که روش فازی شامل دو گروه است که گروه اول با محاسبه وزن معیارها و دیگری با محاسبه وزن زیرمعیارها و همچنین نتایج حاصل از منطق بولین با پنج طبقه که شامل محاسبه وزن معیارها و زیرمعیارها می‌باشد.
یافته‌ها: نتایج این پژوهش نشان داد که روش‌های فازی و بولین یاد شده به‌ترتیب 34، 48779، 16000 و 7630 هکتار از اراضی شهرستان نایین را بسیار مناسب برای ایجاد لندفیل شهری تشخیص داده‌اند. تلفیق این چهار روش که باتوجه به وزن هرکدام از آن‌ها صورت گرفته است منتج به یک نقشه واحد با چهار لکه اصلی شد که مجموعاً حدود 5055 هکتار را شامل می‌شود.
نتیجه‌گیری: یافته‌های این پژوهش نشان می‌دهد که تلفیق نتایج حاصل از منطق فازی و بولین اراضی بهتری را برای ایجاد لندفیل نسبت به هر یک از روش‌ها ارائه می‌دهد.

چکیده [English]
Background and purpose: In recent years, the rapid growth of cities has been led to an increase in the production of various types of solid wastes in urban areas. Although landfilling is the last step in municipal solid waste management, but it is one of the common methods in developing countries’ municipal solid waste management. The purpose of this study is to accurately locate urban landfills in Naien county by using a combination of fuzzy and boolean methods.
Materials and methods: In this study, AHP model was used to standardize and determine the weight of criteria and sub-criteria. The innovation of this research is the combination of the results of fuzzy and boolean logic. The fuzzy method consists of two groups, the first group is calculation the weight of criteria and the other one by calculating the weight of sub-criteria, and the results of boolean logic with five classes including calculation the weight of criteria and sub-criteria.
Results: The results of this study show that the mentioned fuzzy and boolean methods have identified 34, 48779, 16000 and 7630 hectares of areas in Nain county as the most suitable areas for creating urban landfills. According to the weight of methods, a single map with four main patches is resulted by combination of these four methods, which includes a total of 5055 hectares in Nain.
Conclusion: The results of this study show that the combination of fuzzy and boolean logic results provides better areas for landfill than using the methods individually.
