The link counts are usually inaccurate under the influence of measurement and sampling errors, all kinds of adventive events and succedent data processing errors. Ignoring data inaccurateness may lead to unacceptable error of O-D matrices estimation. To make the best of the fuzzy information acquired from traffic survey, this paper presents a bi-level programming model with fuzzy expected value model...
In this paper, the algebraic structure for a class of point fuzzy numbers are investigated that new algebraic operations about point fuzzy numbers are presented, such that point fuzzy numbers set F(R) are F-Abel group, F-linear space, and F-commutative algebra, respectively. Example is also given to illustrate our results.
