| Abstract: | Aiming at the reliability and topology stability, the concepts of connectivity reliability and structure entropy are introduced respectively into transportation system, and the optimal objectives of the system is im- proved. By constructing the multi-objective model of connectivity reliability and structure entropy-based dis- crete transportation network design, the programming problem is solved using the cross-entropy algorithm. The results indicate that it is feasible to make both eonneetivity reliability and structure entropy as optimal objec- tives for the system. |
