    Abstract
  • Aiming at problem that existing network planning model incarnates specific time and path length prominently instead of its core float and path length difference, which makes obstacles common exist when using the model in practice, dual model of network planning model was founded by using dual theory. Firstly, path length theorem was deduced by analyzing relation between float and path length; Secondly, based on path length theorem, dual network model was founded by using dual theory, and its properties were analyzed; Thirdly, dual equivalence property of network planning was revealed by using the model; Finally, the model was validated and illuminated by illustration. The dual network model incarnates float and path length difference prominently, which makes network planning have more prominent pertinence and validity.
