Constraints

On this screen, the user will define the rate limit and interrupts for each constraint in the model.

The Constraint block can represent:

  • Machine, System, Sub-component

  • Processes material based on rate per time unit

  • Process Interrupts - random and re-supply, etc

The Constraint block is your high-speed machine running and running.

When the machine is running it tracks material production, but there are many things that can happens to stop the flow of production:

  • Machine Failure

  • Scheduled Event

  • Operational Decision

In real systems we have data being collected: this is often referred to as stops data or Line Event Data System (LEDS) Data.

When we transform the LEDS Data from being a Stop to an Interrupt. The Interrupt models the underlying distributions for TTF/TTR.
