Flowchart modules1. Create module2. Dispose module3. Process module4. Decide module

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 modulesData 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.
