We generalize Monge property of real matrices for interval matrices. We define two classes of interval matrices with Monge property - in a strong and in a weak sense. ...
We study fundamental properties of both classes. We show several different characterizations of the strong Monge property. ...
We presented lists of closure properties under operations on ISM and IWM and under operations combining both classes of matrices. ...

We first deal with the special case of Cl bottleneck Monge matrices. Next, we derive several fundamental properties on the combinatorial structure of bottleneck Monge matrices with arbitrary entries. ...
The matrix A is termed permuted bottleneck Monge matrix, if there exist row and column permutations such that the permuted matrix becomes a bottleneck Monge matrix. ...
On the one hand, we obtain a better understanding of bottleneck Monge matrices which facilitates the recognition of permuted bottleneck Monge matrices. ...
