Sankey charts are a powerful tool for visualizing and understanding complex processes, particularly in the field of logistics and supply chain management. They are named after their creator, Charles Sankey, a British engineer and statistician who developed the chart in the early 20th century. Sankey charts are used to show the flow of materials, goods, or information, from one point to another, and can be used to identify bottlenecks, inefficiencies, and opportunities for improvement in a given process.

One of the key advantages of Sankey charts is their ability to show the flow of materials or information between multiple points or actors. This makes them ideal for visualizing supply chain processes, where multiple suppliers, distributors, and customers are involved. Sankey charts also allow for the easy identification of various stages in the process, such as assembly, processing, or packaging, which can help identify opportunities for improving the overall efficiency of the process.

Another important aspect of Sankey charts is their ability to show the direction of the flow. Sankey charts use arrows to indicate the direction of the flow, with the arrowheads pointing from the source to the sink. This makes it easy to identify which direction the flow is moving in, and to understand the overall direction of the process.

When it comes to creating a Sankey chart, there are a few key steps involved. First, you need to define the source and sink of the process, which represents the starting and ending points of the flow. Next, you need to identify the various stages in the process, and assign them to the appropriate nodes in the chart. Finally, you need to connect the nodes in the chart to represent the flow of materials or information between the nodes.

Once the chart is created, it can be easily customized and refined to show the process in more detail. For example, you can add additional nodes to represent intermediate stages or steps, or you can change the colors or symbols used to represent the different nodes. You can also add labels to the nodes to provide additional information, such as the names of the suppliers or customers involved in the process.

In conclusion, Sankey charts are a valuable tool for visualizing and understanding complex processes, particularly in the field of logistics and supply chain management. They allow for the easy identification of bottlenecks, inefficiencies, and opportunities for improvement in a given process, and can be customized and refined to show the process in more detail. Whether you are an engineer, a manager, or a researcher, Sankey charts offer a powerful way to gain insight into the flow of materials or information in a given process.
