Simulation models can be used to help understand requirements of a stockyard layout. However, simulation models can be complex, are difficult to use and may be unsuitable for use in early stages of a project. This paper presents a simple set of equations that can be used for “back of the envelope” calculations that are based on Queuing or Waiting Line Models. These equations can help provide a better understanding of the issues and constraints within stockyard operations during the initial stages of development. The use of these simple tools is illustrated by some examples.
