It is a descriptive model available for further analysis. A commentator of a cricket match describes the play as model to enable us to predict the future course of events of the play. Adjustment with changing situations cannot be done in this model.Ī model is a vehicle for arriving awell structured problem of reality. It is not possible to make any modification of the model.Ĥ. It cannot be used to study the changes in the operation of the system.ģ.

This model is not suited for further manipulation.Ģ. It is easy to study the model than the system itself.ġ. In other words, they are the images of areal object.ģ. In general, they enlarge or reduce the size of a real system. A globe is an iconic model of the earth, a photograph is also an iconic model. A toy automobile is a iconic model of a real automobile. are all examples of models.Ī iconic model is a physical representation of a real project on a different scale. A map of multiple activity char, a project network, the representation of the behavious of a queuing system, a model to forecast the future, abased on the past and the present factors of a time series, etc. The objective of a model is to provide means for analysing the behavious of the system for further improvement. Great efforts have been taken by experts to model business situations, military operations, motion of planets and stars, congestion in traffic places and so on.Ī model is an abstraction or an idealised representation of a real life proble. Modelling a real life situation helps us to study the different behaviour of the proble corresponding to the description of the problem.
