Highway Construction Network Diagram Optimization

Based on the problem and shortage in traditional method of network optimization for highway engineering, using Hybrid approach and Genetic Algorithm improve and adjust the project schedule in highway construction from the following facets: time, cost and resource. Establishes the mathematic models, presents detail solution process. At the same time, for the first time from the point of the view of he biggest benefit ?in engineering construction, establishes the colligation mathematic model and presents the solution method. Using the GAs improves the network in highway construction ,for the first time gives the fitness function and expatiate the GAs?design in network optimization, presents the optimal value of GAs?parameters, draws the flowcharts. This paper close combine the instance, and makes out the compare based on the HuaLin project sect of Jinghu highway.
