The aim of this paper is to create a nexus between postmodern consumer behaviour and fuzzy clustering, and to propose a suitable clustering method to segment postmodern consumers. From a methodological perspective, the main contribution of this paper is related to the use of the fuzzy theory...

Confronted with negative environmental impacts, rising fuel costs and increas-ing congestion, many cities are implementing sustainable mobility measures to improve the flow of passenger and goods. Examples of these measures are use of public transport, cycling, walking, energy efficient...

We propose a generalization of the Hukuhara difference. First, the case of compact convex sets is examined; then, the results are applied to generalize the Hukuhara difference of fuzzy numbers, using their compact and convex level-cuts. Finally, a similar approach is seggested to attempt a...

Real Options analysis offers interesting insights on the value of assets and on the profitability of investments, which has made real options a growing field of academic research and practical application. Real option valuation is, however, often found to be difficult to understand and to...

We consider a discrete-time model for the cash flow of an insurance portfolio/business in which the net losses are random variables, while the return rates are fuzzy numbers. We choose the shape of these fuzzy numbers trapezoidal, Gaussian or lognormal, the last one having a more flexible shape...

In this paper we show that the possibilistic mean values produce computation results that may differ in a non trivial may from those obtained with the fuzzy extension principle. The evidence is carried out by comparing some examples derived from several models in finance and economics.

In this paper we show how a fuzzification process can benefit of the F-transform and possibility distributions.

Among the elements that are used to make the economical-financial analysis of a firm, we can mention ratios, which offer a wide range of possibilities to determine the situation of the company in a particular moment, as well as its evolution in time, and its position com-pared with other firms....

This paper analyzes 21 years of data related to unintentional hazardous materials (hazmat) releases on air, marine, and rail transportation modes reported in the United States (U.S.) -- although their origins and destinations may be outside the U.S. The authors' analysis reveals thousands of...
