建筑供应链中基于空间约束的多供应商横向协同研究

针对由多个建筑材料供应商和一个总承包商组成的建筑供应链,研究了在建筑材料存放空间约束的条件下,不确定的多个供应商如何进行横向地协同供应,从而使得总承包商的期望总成本最低的问题。通过供应链中的信息共享,建立了多供应商横向协同的基本模型;再通过产能外包或加班赶工的方式,建立了多供应商横向协同的高级模型,并给出了模型的求解步骤。最后使用了Monte Carlo方法来模拟材料供应的整个过程,仿真结果显示:相对于传统的供应模型,两种协同模型均能有效地减低总承包商的期望总成本。基本模型所花费的代价最小,高级模型能够显著降低建筑工期延误成本,从而实现建筑供应链的帕累托改善。

Research on Multi-suppliers Horizontally Synchronization Based on Space-constrained Construction Supply Chain

A construction supply chain consisting of multi-suppliers and one main contractor is considered, in the context of constrained building material space. How multi uncertain suppliers horizontally synchronized supply to reduce the main contractor’s expected total cost is identified. Through information sharing among supply chain, multi-suppliers horizontally synchronized basic model is presented. Then through capacity outsourcing or expediting, multi-suppliers horizontally synchronized advanced model is presented. Finally, the whole proceed of building material supply is simulated by Monte Carlo methodology. The result shows: compared with traditional supply model, these two synchronized model can decrease the main contractor’s expected total cost effectively. The basic model’s cost is minimum, and the advanced model can reduce the cost of construction duration delay. Pareto improvement of construction supply chain is achieved.
