SE2 - Lesson 2 (Introduction to System and Analysis - Part 2)

Also called probabilistic systems, are those in which the output, or results, cannot be determined precisely, but only be guessed at.

• Open Systems

• Closed Systems

These systems involve elements of chance or probability.

• Open Systems

• Closed Systems

Ex: In an airline reservation system, the number of individuals who will purchase a ticket for a given flight cannot be predicted with certainty.

• Open Systems

• Closed Systems

The result or output can be predicted with certainty.

• Open Systems

• Closed Systems

The output of closed systems can be predicted with relative ease and accuracy by measuring the ____ or ______ placed upon the system.

• input

• demands

• output

• users

Closed systems are easier to manage than open systems.

• True

• False

Ex: An airfreight carrier agrees to ship a fixed number of packages for the same customer each day.

The number, weight, and destination of the shipments never change.

• Open Systems

• Closed Systems

These are tangible entities. We can touch and feel them.

• Physical Systems

• Abstract Systems

Physical systems is not static or dynamic in nature.

• True

• False

[Physical Systems]

Ex: Desks and chairs of a computer center.

• Static

• Dynamic
