基于模糊可能性理论,研究了2-型模糊供应链网络设计问题。考虑到运输费用和顾客需求的不确定性,我们用2-型模糊变量来刻画,建立了2-型模糊环境下的期望值供应链网络设计模型。当2-型模糊变量相互独立且服从三角分布时,我们将原模型转化为等价的确定模型。等价模型是一个0-1混合整数参数规划,因此可采用Lingo软件求解。最后,我们通过数值例子演示所提建模思想。实验结果证明了所建模型的有效性。
Based on fuzzy probability theory, the design of 2-type fuzzy supply chain network is studied. Considering the uncertainty of transportation cost and customer demand, we use 2-type fuzzy variables to characterize and establish the expected value supply chain network design model in 2-type fuzzy environment. When 2-type fuzzy variables are independent of each other and follow a triangular distribution, we transform the original model into an equivalent deterministic model. The equivalent model is a 0-1 mixed integer parameter planning, so Lingo software can be used to solve. Finally, we demonstrate the proposed modeling ideas through numerical examples. The experimental results show the effectiveness of the proposed model.
