Systems MODELS :

Schematic Models : 

• A schematic model is a 2-D chart that shows system elements and their linkages.
• Different arrows are used to show information flow, material flow, and information feedback.

Flow System Models :

• A flow system model shows the orderly flow of the material, energy, and information that hold the system together.
• Program Evaluation and Review Technique (PERT), for example, is used to ABSTRACT a REAL world system in model form.

Static System Models : 

• They represent one pair of relationships such as activity–time or cost–quantity.
• The Gantt chart, for example, gives a static picture of an activity-time relationship.

Dynamic System Models :  Business organizations are dynamic systems. A dynamic model approximates the TYPE of organization or application that analysts deal with. It shows an ongoing, constantly changing status of the system. It consists of −

• Inputs that enter the system
• The processor through which transformation takes place
• The program(s) required for processing
• The output(s) that result from processing.
