In this paper, we discuss the design and optimization of supply chains at Dow AgroSciences. We start by introducing the design components of a typical supply chain. We then discuss the typical inputs required in a model and the type of outputs generated. Next we consider the strengths and weaknesses of the standard tools that we use as part of the model process.

To show the breadth of problems addressed, three example models are presented. The first problem discusses the complexity of addressing a global supply chain for a new active ingredient. The second problem focused on a regional supply chain. The final problem showed a tactical model looking at rail fleet sizing.

在本文中，我们讨论了陶氏益农的供应链设计和优化。我们首先介绍典型供应链的设计组成部分。然后，我们讨论模型中所需的典型输入以及生成的输出的类型。接下来，我们考虑在建模过程中使用的标准工具的优缺点。

为了显示所解决问题的广度，提出了三个示例模型。第一个问题讨论解决新的活性成分的全球供应链的复杂性。第二个问题集中在区域供应链上。最终的问题显示了一个战术模型，该模型研究了铁路车队的规模。
