云制造下供应链协同运作系统动力学仿真分析

Simulation Analysis for Collaborative Supply Chain Operations with Cloud Manufacturing Based on System Dynamics

摘要:

在云制造环境下，供应链将会呈现出一种全新的制造模式。本文基于系统动力学方法，首先分析了传统制造和云制造的行为模式，利用Vensim软件构建传统制造模型和云制造模型，然后对模型进行一系列测试，证明模型的有效性和稳定性。通过分析不同需求函数情况下主要参考变量的对比结果和不同情况下云制造订单承接比率发现，云制造模式可以有效降低供应链库存水平、提高订单满足率、充分利用企业剩余产能，促进供应链协同化运作。

Abstract:

In the cloud manufacturing environment, the supply chain will present a new manufacturing model. Based on the system dynamics method, this paper first analyzes the behavior patterns of traditional manufacturing and cloud manufacturing, uses Vensim software to build traditional manufacturing models and cloud manufacturing models, and then conducts a series of tests on the models to prove the validity and stability of the models. By analyzing the comparison results of the main reference variables under different demand functions and the order acceptance ratio of cloud manufacturing under different conditions, it is found that the cloud manufacturing model can effectively reduce the inventory level of the supply chain, improve the order fulfillment rate, make full use of the remaining capacity of the enterprise, and promote supply chain collaboration. operation.
