2. Description of the Computer Program:
The basic building blocks for Arena simulation models are called modules. There are two
basic modules - flowchart and data modules and they define the process to be simulated.
Flowchart modules describe the dynamic processes in the model. There are different kinds
of flowchart modules, however for simulation model of M/M/1 queuing system, only three
flowchart modules - Create, Process and Dispose are used.


The create module is the birth node for arrival of entities to the model's boundary. In
this model, it is named "Customer Enters System". Different aspects of this module such as
Time between arrivals, Entity type, Entities per arrival etc can be specified in the
Dialog box or alternatively in the create spreadsheet view, which is included in the
Appendix. For this model, the interarrival time is exponentially distributed with mean 2
minutes and the entity type is customer with 1 entity per arrival.


The process module which is named "Checkout Counter" here represents the cashier, the
service provided, the queue and the entity delay time there. Specific action for this
module can be chosen in the logic area. In this particular case, "Sieze Delay Release" is
chosen so that this module takes care of entity's seizing of Resource, the Delay for a
time representing the service time and then Release units of the Resource for other
