Optimization Study on Resource Equilibrium with Fixed Time Limit for a Project Based on SPSO Algorithm

During the course of construction, how to keep the utilization of resource balance, and avoid frequent and serious peak or low-vale of utilization is an important problem. The reasonable solution of the problem can reduce the scale of temporary establishments and economize expenditure furthest. The algorithm of SPSO was introduced into the optimization solution of resource equilibrium with fixed time limit for a project, the model considering multi-resource optimization was established and was improved at the aspect of algorithm to make it more adaptable to the calculation of SPSO. The sample analysis shows that the SPSO is superior to the traditional methods in resource optimization, and it can not only converge on the globally optimal solution effectively but also achieve different optimization schemes to provide several schemes for construction decision-making. The research fruits have important reference value on the construction management plan of a project.
