摘要：
We first generalize the Perron-Frobenius results for nonnegative matrices to nonnegative fuzzy matrices which says that these fuzzy matrices have a (dominant) nonnegative fuzzy eigenvalue. This result is then used to extend Leontief's closed input-output analysis to fuzzy economies and obtain a fuzzy model of the world's economy. © 1990.
