0-1 Integer Programming Model and Parallel Algorithm for Location of Logistics Distribution Centers
Abstract:According to the theory of 0-1 programming, this paper presents the model for the problem of logistics distribution centers location. And a new parallel algorithm for the proposed model is given based on objective values sorting and improved PSRS. The tasks of verify solutions have been partitioned and submited to p processors, which verify solutions in parallel. The proposed method have excellent speed up in p.
