In order to improve the logistics network of timber which could provide guarantee for the smooth running of timber logistics and reduce the cost of the whole area of timber logistics system, combining the production reality of timber logistics, the optimized mathematical model of logistics network of timber was established using the strategies and processes of genetic-tabu (GA-TS) algorithm.Setting the timber logistics activities of Yonglin group as an example to analyze the empirical analysis of the timber logistics network optimization.The model and algorithm were combined with computer technology.Solver procedure was written by C# and geographical information systems software platform (ArcGIS) was used to implement scheme visualization.Results showed that the model and the algorithm are feasibility and effectiveness, can improve the efficiency and precision of timber logistics network optimization decision, and reduce logistics cost.
