The article is an introduction to the concept of granular computing. It discusses the fundamental concepts related to information granules. It also presents a general scheme of the concept, which was used to implement an intelligent interactive system. The system is entirely based on the concept of computing with information granules, thus serving as a practical example of its application in intelligent technical, economic, and other systems.The term granular information appeared in Zadeh’s early works in connection with his research on fuzzy set theory [21]. However, the concept of computing with information granules itself appeared at the very end of the 20th century. It complements concepts known for years, such as interval analysis, rough and fuzzy set theory, cluster analysis, the divide and conquer strategy, and many others [2].
In 1997, Lin proposed the term granular computing to describe this new, extremely rapidly developing field [19].
What is granular computing? Despite the attempts of many researchers, it is difficult to provide a precise definition [20]. Any specific definition could omit some of the important aspects of this relatively new concept. (…)
