Research on the application of optimization algorithms in engineering management and its practice in project scheduling

Currently, there are still problems of cost overruns and resource squandering in engineering management, which cannot ensure that project schedules, quality, and costs are up to standard. This paper focuses on the analysis of the critical path of engineering management projects using the earned value method, focusing on the schedule and cost deviations of activities on the critical path and identifying the problems to improve project profits and reduce costs. Applying the methodology of this paper on a bridge project, we find the root causes of cost overruns by drawing network diagrams, calculating the Earned Value parameters and cost deviations, and propose targeted improvement measures to reduce the total project cost. The final project works were completed ahead of schedule, and in the first five months of the critical path A, E, F are serious cost deviations, the last three months of the balance of more than 90,000 yuan, the cost control target is also exceeded. The research in this paper demonstrates the dynamic measurement in the engineering process and proves that the critical path earned value method is a practical cost control method for engineering management.
