Research on Multi-objective Equilibrium Optimization for Construction of Rail Transit Station Projects
In response to the complex construction issues of rail transit station projects,a balanced opti-mization strategy is proposed for comprehensive construction period,cost,quality,and safety objectives.Based on the analysis of the correlation between the four objectives of construction period,cost,quality,and safety,a multi-objective equilibrium optimization model is established.Combining the principle of multi-attribute u-tility,construct an objective function for multi-objective optimization;Based on particle swarm optimization al-gorithm,optimize and solve multivariable problems.The example data shows that under the premise of ensur-ing quality and safety indicators,the total construction period after balanced optimization is 538 days,which meets the requirements of the construction period;After balanced optimization,the total cost is 54.73 million yuan,achieving a gross profit margin of 37.1％and a considerable profit margin.
