A STUDY ON A COMBINATION OF FUZZY COGNITIVE MAP MODEL AND CONFLICTING BIFUZZY SET THEORY ON THE IMPACT OF CHENNAI FLOOD

The flood is the alarming rate in India's teeming cities. Heavy rain is one of the reasons for the dangerous flood. Losses are unavoidable when there is more rain. But speed recovery and relief are the precaution for the major losses. In India, Chennai is one of the largest industrial and trading hubs.
