  • Carrier selection method for logistics network
    Patent number: 8600908
    Abstract: A carrier selection method for the logistics network is disclosed to evaluate the network reliability of each carrier set for choosing an optimal carrier set. The logistics network includes a start, a terminal and a plurality of routes between the start and the terminal, and a plurality of minimal paths are composed of the routes. The carrier set is composed of carriers chosen in every route of the logistics network. The carrier selection method includes the steps of choosing one carrier for transporting; distributing a demand in the minimal paths, and each carrier having a plurality of capacities and a maximal capacity; calculating a network reliability for the carrier set transporting the demand in the minimal paths according to the demand, the capacities and the maximal capacity; and executing genetic algorithm for searching an optimal carrier set.

  • Method for assigning transmission line of electric network
    Patent number: 8538594
    Abstract: A method for assigning transmission line of electric network, which is used to select an optimal transmission assignment from a plurality of transmission assignment, is disclosed. The steps of the method includes: assigning a transmission line between a source and a relay node and another transmission line between the relay node and a sink to form one of the transmission assignments, and the states of the two transmission line are different; computing a network reliability of each transmission assignment; executing an algorithm to generate two offspring transmission assignments for replacing two of the transmission assignments, and the network reliabilities of the two of the transmission assignments are minimum; computing the network reliabilities for the two offspring transmission assignments; and selecting one of the transmission assignments with the maximal network reliability being the optimal transmission assignment.
