This is a geometrical notion and has applications far<br /><span>beyond the scope of its definition. Besides the importance of measuring compactness in a<br /><span>single object, its study is significant in real-world applications, where the integration of<br /><span>items or objects in conjunction with each other is considered. Regionalization is the term<br /><span>commonly used for this integrative perspective. Although there are several methods to<br /><span>quantify compactness, this study tries to illustrate the simple way for its calculation. Hence,<br /><span>this study is devised to apply with some modifications one of the methods that has been<br /><span>suggested for calculating single object compactness in regionalization domain. We attempt<br /><span>to propose a clear definition and to evaluate the computer implementation of the<br /><span>compactness in a land-use planning study. The ant colony algorithm as a heuristic approach<br /><span>was applied to measure compactness in an innovative manner and to incorporate this<br /><span>concept into a land-use planning case. Results show that this method can be useful in<br /><span>achieving compactness in land-use planning.</span></span></span></span></span></span></span></span></span></span></span></span></span><br /></span> https://ijerr.gau.ac.ir/article_3875_5d84a5721a39b56611bbe36da58811f1.pdf
