摘要
文章以装配式预制构件生产为研究对象,梳理影响预制构件生产成本的因素,运用系统动力学(SD)方法构建预制构件生产成本系统流图;通过灵敏度分析,得出影响预制构件生产成本的5个主要因素;通过确定预制构件生产成本目标函数及约束条件,构建基于“成本—进度”双重目标的多目标优化(MOP)模型,以获取最优生产方案。在此基础上,以某预制构件厂为实例分析验证,结果显示:优化后的预制构件生产成本、进度均得到明显改善,模型优化效果明显。
This paper takes the production of prefabricated components for assembly use as the research object,and sorts out the factors that influence the production cost of prefabricated components.System dynamics(SD)is applied to construct the cost flow diagram for prefabricated component production.With sensitivity analysis,5 major factors influencing the production cost of prefabricated component are obtained.And,by determining the cost objective function of prefabricated component production and the constraints,a model of multiobjective optimization problem(MOP)based on dual objectives of“cost-schedule”is built to acquire the optimal scheme of production.Based on the above,a factory that manufactures prefabricated component is taken for demonstration and the result shows:the cost and schedule of prefabricated component are both improved evidently,and the built model has apparent effect for optimization.
