摘要
为了研究建筑废料现场管理的优化决策问题,在明确废料现场管理有效性最大化、成本最小化和时间最小化三大目标的基础上,设计了废料管理多目标优化模型框架,建立了相应的数学模型,应用多目标遗传算法NSGA-II对模型进行求解,并借助MATLAB工具进行算法编程。通过实例应用分析,找出了各种资源因素的最佳组合方式,决策者可根据实际项目对成本、时间和废料管理有效性的要求,以及项目自身特点和资源条件,选择最为合适的废料现场管理方案。
To achieve the optimization of decision-making of construction waste field management system,a framework for multi-objective optimization of waste management is developed considering three objectives,which are effectiveness,cost and time.A model is solved by multi-objective genetic algorithm NSGA-II.An application example is analyzed according to practical requirements and conditions,to illustrate the use of the model and to demonstrate its capabilities in generation and visualizing optimization among waste management effectiveness,cost and time.
