We consider the bicriterion multi modal assignment problem which is a new generalization of the classical linear assignment problem. A two-phase solution method using an effective ranking scheme is presented. The algorithm is valid for generating all nondominated criterion points or an approximation.

Extensive computational results are conducted on a large library of test instances to test the performance of the algorithm and to identify hard test instances.

Also, test results of the algorithm applied to the bicriterion assignment problem is given. Here our algorithm outperforms all previously known exact solution methods for this problem class.
