COMMON PROCESSES OF DISCRETE SYSTEM
Entities movement:
Case - 1
1. Entities enter the system as input through boundary
2. Move between the components within the system
3. Leaves the system through boundary as output
Case - 2
1. System may initially contain some entities
2. Circulate between the components within the system
3. Leave the system (in whole or in part) through boundary as output
Case - 3
1. Entities may never leave the system boundary
Entity creation:
To create entities as inputs to the system:
1. Customer arriving at a bank
2. Car arriving at an intersection
To create entities as inputs to the system, a common process acting as an entity source should be considered. The module representing this process is called source, create, generate and so on by different simulation language.
Properties of module:
1. The module should allow for the setting the time of creation of the first entity. This value may be constant or random variable.
2. Module should provide for the selection of the time between entity arrivals which may be constant or random variable.
3. Module should allow for the assignment of a name to the entities created. This name will be assigned to the entity as an attributes.
