SIMULATION

Simulation is the imitation of the operation of a real world process or system over time. It is a numerical technique for conducting experiments that involve certain types of mathematical and system over extended period of time.

Applications of simulation

• Manufacturing systems
• Public and transportation systems
• Restaurant and entertainment systems
• Computer system performance 

system and system environment in simulation

• A system is defined as the collection of objects / ideas which permits identification as a whole coherent logical functional unit. A system is often affected by changes occurring outside the system. Such changes are said to occur in the system environment.

Types of simulation models

• Based on the representation

                    Physical model

                    Schematic model
                    Symbolic model

• Based on timing nature

                    Static
                    Dynamic
