5. Batch module:

This module is the grouping mechanism within the
simulation model.

Batches can be permanently or temporarily grouped.
Temporary batches must later be split using the
Separate module.

Entities arriving at the Batch module are placed in a
queue until the required number of entities has
accumulated. Once accumulated, a new representative
entity is created.
Batch module cont.
Typical uses:
 Collect a number of parts before starting
processing
 Reassemble previously separated copies of a
form
 Bring together a patient and his record before
commencing an appointment
Batch module cont.
6. Separate module:

This module can be used to either copy an incoming
entity into multiple entities or to split a previously
batched entity.

When splitting existing batches, the temporary
representative entity that was formed is disposed and the
original entities that formed the group are recovered.

The entities proceed sequentially from the module in the
same order in which they originally were added to the
batch.
Separate module cont.

When duplicating entities, the specified number of copies
is made and sent from the module. The original incoming
entity also leaves the module
Typical uses:

Send individual entities to represent boxes removed from
a container

Send an order both to fulfillment and billing for parallel
processing

Separate a previously batched set of documents
Separate module cont.
7. Assign module:
Used for assigning new values to variables, entity attributes,
entity types, entity pictures, or other system variables.
Typical uses:

Accumulate the number of subassemblies added to a part

Change an entity’s type to represent the customer copy
of a multi-page form

Establish a customer’s priority
Assign module cont.
8. Record module:

This module is used to collect statistics in the
simulation model
Typical uses:

Collect the number of jobs completed each hour

Count how many orders have been late being fulfilled

Record the time spent by priority customers in the
main check-out line
Simulate and animate the
following system:
A car repair has 2 workers working in it. One of
them is professional and skilled and repairs small
vehicles (Vans). While the other one is not skilled
as much and repairs large vehicles (Trucks).
 Vans arrive to the car repair with an exponential
distribution every 15 minutes. And need around
(5 minutes- normal distribution- standard
deviation :1) to be repaired.
 Trucks arrive to the car repair with an
exponential distribution every 10 minutes. And
need around (6 minutes - normal distribution standard deviation :1) to be repaired.

Data modules
Data modules are the set of objects in
the spreadsheet view of the model that
define the
 characteristics of various process
elements, such as resources and queues.
