1. Brief description

The supply forms the system boundary and is also the interface to the upstream process, which is not part of the model.

2. Procedure and control description

The Supply element as a system boundary can be used in different ways in the model.

For example, the primary material flow (main flow) such as for products, containers, bottles, etc. or secondary material flows (secondary flows) for packaging materials such as cardboard blanks for collective packaging, caps, labels, products, etc. can be modeled with the Supply.

The material is fed continuously without interruption as a constant material flow (no cycle time fluctuations) with the set cycle time.

The Supply performance (cycle time value) and a failure behaviour (availability and MTTR) can be parameterized for the Supply. In the default setting, the failure behavior is deactivated.

Figure 1 shows different variants of the feed.

Parameter	Required	Description
Name	x	Name of the element
Supply	x	Supply behavior
Quantity	x	Supply behavior
Value [pcs/min]	x	Number of products supplied per minute
Own fault active	x	Activate/deactivate failure
Reliability [%]	x	Percentage of time the process operates or functions without any disruption. Defects are randomly generated only during the work phase of the process on a unit/part.
MTTR - Distribution	x	Distribution function for MTTR
Mean [s]	x	The average time required to repair a machine at the time of failure. MTTR is generally calculated by adding the TTR (time to repair) of all failures divided by the total number of failures.
