Research On Progress-Cost Problem Of Viaduct Project Based On Genetic Algorithm

With the rapid development of the economy and the improvement of the quality of life,the demand for infrastructure has also increased.In recent years,investment in large-scale highways,railways and municipal bridges has been significantly improved.Such as in some infrastructure projects,in the development of specific project construction plan in the process,it is necessary to consider whether the progress of the project to meet the scheduled project construction needs,but also to control the cost of the project Within reasonable limits.And the project progress,cost and quality of project management is the eternal three management goals.Then in the actual project management,you need to optimize some of the processing,most of the progress of the cost of optimization methods to manage the three major objectives,that is,under the premise of quality assurance,by increasing the cost of project activities to reduce the progress of the least cost Increase meet the project schedule shortening requirements.In this paper,taking the urban viaduct project as an example,under the precondition of guaranteeing the quality and safety,this paper finds out the control points of the progress-cost mutual restraint and coordination of the viaduct project,and studies the schedule-cost optimization of the project,and makes the viaduct project The completion of the progress of the plan,and to minimize the project construction costs,get the maximum benefit.In the study,the problem of "schedule-cost optimization of viaduct project" will be analyzed based on genetic algorithm to ensure that the optimized construction plan can be worked out.And the dynamic management of the viaduct project,the establishment of project progress-cost optimization model to control the progress of the project and cost,so that the progress of the project-the cost is controlled in a reasonable range,so that the viaduct project construction can achieve better Economic and social benefits.And through the specific viaduct project-cost optimization verification,indicating that the model is feasible and effective,and China's construction projects have a positive role in promoting.
