摘要
为了在考虑资源价格变动的情况下,对已根据属性分类后的资源进行资源均衡,本研究基于一电力工程项目,构建在消耗性资源成本约束下的非消耗性资源均衡优化整数线性规划模型,并用所建模型对选取的工程项目进行资源均衡优化,最后用优化后的资源峰值在该工程项目的BIM4D模型中进行受限分析。研究结果表明,该整数线性规划模型对降低资源成本和资源用量峰值具有较好的效果,且满足施工过程中的空间受限。
In order to balance resources that have been classified according to attributes while considering changes in resource prices,this study is based on an electric power project,establishes a non-depletable resource balance optimization integer linear programming model under the constraint of consumable resource costs.The constructed model is then applied to optimize resource balance for selected engineering projects.Finally,the optimized resource peaks are analyzed within the BIM4D model of the project under spatial constraints.The research results indicate that the integer linear programming model effectively reduces resource costs and peak resource usage,while meeting spatial constraints during the construction process.
