Sankey charts are a type of flowchart that are used to visualize the flow of materials, energy, or information through a system. They are particularly useful for identifying opportunities for resource optimization and waste reduction. In this article, we will explore the basics of Sankey chart creation, as well as some practical applications for using these powerful visualization tools.

What is a Sankey Chart?

Sankey charts are a type of flowchart that use arrows to represent the flow of materials, energy, or information through a system. The chart is named after the British engineer Charles Sankey, who first developed the chart in the early 20th century. Sankey charts are particularly useful for identifying opportunities for resource optimization and waste reduction.

How to Create a Sankey Chart

Creating a Sankey chart is relatively simple. The first step is to identify the input and output nodes in your system. These nodes represent the starting and ending points of the flow of materials, energy, or information. Next, you need to determine the flow rates between each pair of nodes. Flow rates represent the amount of material, energy, or information that flows through each node. Finally, you can use software such as Microsoft Visio or Lucidchart to create the chart using pre-defined templates or by manually adding nodes and arrows.

Applications of Sankey Charts

Sankey charts have a wide range of applications in fields such as engineering, logistics, and environmental management. Some of the key applications include:

1. Resource Optimization: Sankey charts can be used to identify opportunities for optimizing resource allocation within a system. For example, you can use a Sankey chart to visualize the flow of materials through a manufacturing process and identify areas where resources are being wasted or underutilized.
2. Waste Reduction: Sankey charts can also be used to identify opportunities for reducing waste in a system. For example, you can use a Sankey chart to visualize the flow of materials through a recycling center and identify areas where waste could be reduced or eliminated altogether.
3. Energy Efficiency: Sankey charts can be used to visualize the flow of energy through a system and identify opportunities for improving efficiency. For example, you can use a Sankey chart to visualize the flow of energy through an industrial process and identify areas where energy could be saved or wasted less effectively.
4. Environmental Management: Sankey charts can be used to visualize the flow of materials, energy, or information through an ecosystem and identify opportunities for improving sustainability and reducing waste. For example, you can use a Sankey chart to visualize the flow of carbon dioxide through a forest ecosystem and identify areas where carbon sequestration could be improved or enhanced biodiversity could be protected more effectively.

Conclusion

In conclusion, Sankey charts are an effective way to visualize data flow in systems and identify opportunities for optimizing resource allocation and reducing waste. They are particularly useful in fields such as engineering, logistics, environmental management, and more. By creating and using Sankey charts effectively, you can gain valuable insights into your systems and make informed decisions about how to improve efficiency and sustainability.
