Limits

For each machine or Constraint in the model, the user will set the max rate, referred to as the limit, of the node. The limit represents the maximum potential rate of flow through the node. The actual rate in the model will depend on dynamic factors, such as:

  • Whether the node is down due to an internal interrupt.

  • The potential rate from upstream in the structure. This node is starved when the upstream potential to deliver product is less than what it can process.

  • The potential rate downstream in the structure. This node is blocked when the downstream potential to accept product is less than what this node can process.

Anytime a rate changes in the DRS network during a simulation, all of the actual rates equilibrate based on the potential and actual rates throughout the network.
