Modified Logistic Membership function for Poverty Measure
In this paper, new fuzzy poverty index based methodology using a specific membership
function, named as modified logistic membership function, is proposed. The modified logistic
membership function is first formulated for several states of poverty and its flexibility in
taking up vagueness in poverty is established by an analytical approach using aggregate
operators in order to infer a logical conclusion measuring poverty. An application based on
individual well-being data from Tunisian households in 2010 is presented to illustrate use of
proposed concepts.
