چکیده

 به منظور تشریح فرآیند ژنرالیزاسیون براى طبقاتى از پدیده ‏هاى انتخابى، به بیان توالى و ترتیب احتمالى پرداخته و مشخص مى‏ سازد از کدام عملگرها (اپراتورها) و الگوریتم‏ هاى ژنرالیزاسیون استفاده خواهد شد. عملگر ژنرالیزاسیون از نظر نوع تبدیل «ژنرالیزاسیون» را مشخص مى‏ کند که باید واقع شود، سپس الگوریتم ژنرالیزاسیون براى پیاده کردن تبدیل خاص مورد استفاده قرار مى‏ گیرد. در ارائه گزارش مشخصه ‏ها از سرى نقشه‏ هاى پوششى کشور سوئیس استفاده مى‏ شود.

چکیده [English]

In order to describe the generalization process for classes of selective phenomena, we describe the sequence and probable order and determine which operators and generalization algorithms will be used. The generalization operator specifies the type of "generalization" conversion that must be applied, then the generalization algorithm is used to implement a particular conversion. In the presentation of the characteristics report a series of covering maps of Switzerland is used.
