基于Arena仿真的建筑供应链投资RFID成本分摊研究

A Cost Allocation Study on Construction Supply Chain Investment in RFID based on Arena Simulation

实验表明RFID技术能为装配式建筑的管理带来极高的效率,然而RFID技术投资成本较高,目前尚不知如何在供应链间进行成本分摊。以一个预制构件工厂和施工工地的供应链模型为基础,根据南京市某项目的预制外墙板供应链的实际情况,利用Arena软件模拟供应链使用RFID技术和不使用RFID技术相应的总时间和失误情况,对比分析投资RFID技术带来的收益。根据模拟结果计算出投资RFID技术的条件下工厂和工地承担该技术的成本分摊比率,结果表明投资RFID技术显然受益,且定位到构件的概率在50%以上时对供应链双方投资该技术的比率影响较小。

The experiment shows that RFID technology can ensure high management efficiency of prefabricated buildings,but it requires large investments and the way of cost allocation for supply chain members is unclear. This paper presents a supply chain model for offsite factory production and onsite construction. Based on the supply chain of prefabricated concrete exterior wall panels in Nanjing,the total time and errors with and without RFID technology in the supply chain are simulated by Arena software. Thus,the benefits of investing in RFID technology can be compared and analyzed. Through the simulation,the cost-sharing ratio for the plant and site to invest the RFID technology is calculated. The results show that the investment in RFID technology is obviously beneficial. The ratio of both sides in the investments of the RFID technology is less affected when the probability of locating the component is more than 50%.
