Question

Provide an example of one of the three types of models that might apply to designing a car, a house, and an office building.

Answer 1

A representation of information system that is being build is called a model

SO we have three categories of model:-->

1. Textual Model:--> Are used to describe the user requirement . For Example as memos ,reports ,list

2. Graphical Model:--->The complex relationship and requirements that cannot be easily describe using textual model are represented in Graphical Model

3, Mathematical model:--->Used to describe technical aspects of the system which are calculated using the mathematical formulas

So Now lets discuss how these models apply to design a car , office , house

Design of Car

Mathematical model will be used to do the set of calculations for  the horse-power, torque and acceleration etc..

Graphical model will be used to design  3 dimensional drawings of the body style of the car

Textual model will be used to write various specification of the materials that are needed to in designing of the car

Design Of A House

Mathematical model will be used to do the set of calculations to determine angle of roof ,area of house , Size of various parts and types of materials needed.

Graphical model would be a used set of blueprints of the house for references of designer

Textual model would be used to describe the materials to be used and steps in construction process

Design of a Office

Mathematical models : We may need all mathematical models of calculating the stresses and earthquake requirements.,balancing factor etc

Graphical: would be used to prepare the blueprints or even a 3 dimensional physical model.

Textual model :would be used to describe the materials to be used and steps in construction process

So this is how we will use all the three models in design of a car , office and house

IF u like the answer give it a thumbs Up and have any doubt comment it
