Document Summary
Simulation: a model of a complex system and the experimental manipulation of the model to observe the results (dynamic, interactive and complicated are the best) Model: an abstraction of a real system (represents objects within the system and the rules that govern the interactions of the objects. Continuous simulation: treats time as continuous and expresses changes in terms of a set of differential equations that reflect the relationships among the set of characteristics. (ex. Meteorologists models are based on thermodynamics and time-dependent/partial differential equations of fluid mechanics. Entity: the representation of some object in the real system that must be explicitly defined. Attribute: some characteristic of a particular entity. Queuing system: a discrete-event model that uses random numbers to represent the arrival and duration of events. The system is made up of servers and queues of objects to be served. The objective is to utilize the servers as fully as possible while keeping the wait time within a reasonable limit.
