Assignment optimization method for integration and consolidation of logistics tasks with time requirement

The mechanism integrating logistics tasks is the core way for decreasing costs of the logistics centers. Based on the concept of integration and consolidation and the idea of the cofidence interval, this paper develops an assignment model for the integration and consolidation of logistics tasks with time requirement. The paper studies the variant and the decomposition of model, suggests an exchange way for choiced variables to get more degree of integration and consolidation, and presents a method of obtaining initial feasible solution and heuristic algorithm for optimization solution. This paper investigates some properties and rules for fathoming branches and proposes a special branch and bound method for this model. Computational results show that these algorithms are effective.
