Conceptual approach to designing effi cient information systems in the presence of uncertainty

Alekseev A. P.

The paper suggests a way to present a distributed information system as a multicommodity network model that demonstrates the dual character of connections between the elements of the system. The efficiency of such networks is studied regarding their ability to fulfil the requirements of their elements in the presence of uncertainty. Using the concept of the difficulty of achieving the goal, the authors developed an algorithm for analyzing the efficiency of the multicommodity network. The algorithm can be used to assess the efficiency of the system functioning in different conditions with different parameters. The suggested tools help to determine the most efficient version of the system, which can eventually broaden the scope of application domains of such systems.
