Merge module
D ESCRIPTION
The Merge module merges two or more incoming streams from accumulating conveyors
into a single outgoing stream. A product name may be assigned to the outgoing stream.
R EMARKS
Only Conveyor modules can be connected to a Merge module. There is no limit on the
number of incoming conveyors that may be connected to the input of the merge.
If the downstream conveyor cannot accept all of the flow from the upstream conveyors,
each will be adjusted proportionally. Proportions are recalculated any time any flow rate
of any of the conveyors change.
For example, if three conveyors (A, B, and C) each capable of producing 100 units/minute
were merged onto a single conveyor with a flow rate of 150 units/minute, then A, B, and C
would each have a flow rate of (100 * (150/(100+100+100)) = 50 units/minute. If at a later
time, the flow of conveyor A were to stop (perhaps it is starved), then B and C will each be
adjusted to a flow rate of (100 * (150/(100+100)) = 75 units/minute.
Operator module
D ESCRIPTION
The Operator module defines an operator that may be allocated to activities in the system.
Activities include device changeovers (specified in Production and Changeovers dialogs),
device repairs (specified in Reliability dialogs), and scheduled stops of devices (specified
in Scheduled Stops dialogs).
R EMARKS
If a schedule name is specified for an operator, that schedule should be defined using the
Operator Schedule module.
The Operators module may be used in conjunction with the Operator Group module to
define a set of operators that may be referenced with a common name. For example, the
operators Bill, Mary, and Joe may be grouped into a set of operators named Mechanics.
There are three automatic operator states for operators: On-Duty Idle, Working (or User-
Defined), and Off-Duty. An operator is in the state On-Duty Idle whenever the operator is
not busy, but it is on-shift. Upon being allocated to an activity, an operator is automati-
cally assigned the state Working. The Working state may be replaced with a user-defined
state for any activity through a Machine, Conveyor, or Palletizer Operator dialog box (for
the specific activity).
