Labeling loops in stella architect6/20/2023 ![]() ![]() ![]() The conversion process includes the following steps: Specify the Units of All CLD Variables However, by using a modeling program, the end result of the conversion process will be a computer model that you can use to experiment with different policies and see how the system might respond. Although these instructions assume use of one of the inexpensive computer-based modeling packages currently available, you can also draw stock and flow diagrams by hand. In addition, the process reinforces the stock and flow way of thinking by emphasizing the difference between information and material flows, and the importance of unit consistency throughout a diagram. The steps we describe below provide a strong foundation for understanding the connections between CLDs and stocks and flows and add order to an often chaotic process (see “Converting CLDs to Stocks and Flows” on p. Once you have a basic knowledge of stocks and flows, you can begin converting CLDs to stock and flow diagrams.
