DEA-like models for the efficiency evaluation of hierarchically structured units
Article Abstract:
A study shows that the knowledge of the internal structure of decision making units (DMUs) gives different results with respect to the 'black box' perspective when considering data envelopment analysis (DEA) models. One-level and two-level hierarchical structures of the DMU are considered while evaluating the maximum relative efficiency of a DMU.

Scheduling multimodal transportation systems
Article Abstract:
The results on the dynamic multilevel multiitem lot-sizing problem can be generalized to the problem of scheduling a transportation system. A heuristic procedure for scheduling transportation networks mainly devoted to commuters is presented
