MIXED PAPERS LONG QUESTIONS

Paper # 1:

Question No: 23

( Marks: 3 )

Define basic goals of Computer Integrated Manufacturing (CIM) .

Answer: CIM has three basic goals

· Simplification of all manufacturing technologies and techniques

· Automation of as many of the manufacturing processes as possible by integration of

many information technologies.

· Integration and coordination of all the manufacturing aspects through computer

hardware and software

Question No: 25

( Marks: 5 )

Define different models of SDLC?

Answer: Models of System development life cycle:

Waterfall model / Classic lifecycle/ Linear Sequential Model:

The waterfall model is a software development model (a process for the creation of software) in

which development is seen as flowing steadily downwards (like a waterfall) through the various

phases .

Incremental Models: In incremental models, software is built not written. Software is

constructed step by step in the same way a building is constructed. The products is designed,

implemented, integrated and tested as a series of incremental builds, where a build consists of

code pieces from various modules interacting together to provide a specific functional capability

and testable as a whole.

.

Iterative Models: In these models customer feed back is taken at each phase and project is

modified accordingly – if need be. Prototypes are used in these models.

Question No: 26

( Marks: 5 )

Differentiate between Empire Building and Garbage Can Model.

Garbage Can Model:

This model states that organizations are not rational. Decisions made are largely on accidental

basis. Hence wrong solutions may be applied to wrong problems in an organization and critical

mistakes may occur. Information systems should be designed to support and assist in relevant

decision making, instead of making unrelated and wrong decisions.

Empire Building:

Empire building is a business term that refers to a common problem in larger organizations, in

which managers attempt to gather more administrative and financial power. Power can only be

shared in an organization with key employees in terms of their responsibilities & functions. Such

employees are the key players in the decision making process. Hence decisions taken in an

organization are a result of collective efforts of the leaders involved. This model is also termed

as Political Model.

computerized information systems emerged. Now the concept of Information system exists

with the usage and benefits of Computers as an inevitable part. Page#28

Question No: 21 ( Marks: 5 )

Discuss briefly what do you understand by corporate social responsibility (CSR)

Corporate social responsibility (CSR) is an expression used to describe what some see as a

company’s obligation to be sensitive to the needs of not only all of the stakeholders in its

business operations but more importantly the community at large. It has been defined as:

“The continuing commitment by business to behave ethically and contribute to economic

development while improving the quality of life of the workforce and their families as well

as the local community and society as large.”

Businesses are now seen as partners of the communities in which they may be located

rather than simply as a profit making set up serving the needs of their stake holders.

Corporate social responsibility incorporates the principle of sustainable development along with

“triple bottom line reporting” reflecting not only financial results but also social and environmental

impact of the business.

CS507(INFORMATION SYSTEM) MIXED PAPERS LONG QUESTIONS

Differentiate between the following: Computer Aided Design and Computer Aided

Manufacturing

Computer Aided Design :

“It is a system that enables drawings to be constructed on a computer screen and subsequently

stored, manipulated and updated electronically The ability to rotate or create movement in the

design allows testing for clearances and frequently reduces the cost of prototyping the products.

The technology is used for a wide variety of products in such fields as architecture, electronics,

and aerospace, naval, and automotive engineering. Although CAD systems originally merely

automated drafting, they now usually include three-dimensional modeling and computer

simulated operation of the model Rather than having to build prototypes and change components

to determine the effects of tolerance ranges, engineers can use computers to simulate operation to

determine loads and stresses. For example, an automobile manufacturer might use CAD to calculate

the wind drag on several new car-body designs without having to build physical models of each one.

In microelectronics, as devices have become smaller and more complex, CAD has become an

especially important technology. Among the benefits of such systems are lower productdevelopment

costs and a greatly shortened design cycle. While less expensive CAD systems running

on personal computers have become available for do-ityourself home remodeling and simple

drafting, state-of-the-art CAD systems running on workstations and mainframe computers are

increasingly integrated with computer-aided manufacturing systems.

Computer Aided Manufacturing (CAM)

Computer-aided manufacturing (CAM) is a form of automation where computers communicate

work instructions directly to the manufacturing machinery. The technology evolved from the

numerically controlled machines of the 1950s, which were directed by a set of coded instructions

contained in a punched paper tape. Today a single computer can control banks of robotic milling

machines, lathes, welding machines, and other tools, moving the product from machine to

machine as each step in the manufacturing process is completed. Such systems allow easy, fast

reprogramming from the computer, permitting quick implementation of design changes. The

most advanced systems, which are often integrated with computer-aided design systems, can also

manage such tasks as parts ordering, scheduling, and tool replacement. It is a system that uses

computer aided techniques to control production facility. Some of these techniques Are

Computer-aided process planning – Use of computer to control activities and functions to

prepare a detailed set of plans and instructions to produce a machine or part. — Machines

o Computerised Numerical control (CNC) – refers specifically to the computer control of

machine tools for the purpose of (repeatedly) manufacturing complex parts in metal as well as

other materials. e.g. drills, wood routers use this technology.

o Robotics programming – The science or study of the technology associated with the design,

fabrication, theory, and application of robots. – Automobile industry.

25. Identify the situations where Spiral models should be used. (5)

The spiral model, also known as the spiral lifecycle model, is a systems development

lifecycle (SDLC) model used in information technology (IT). This model of development

combines the features of the prototyping model and the waterfall model . The spiral model

is favored for large, expensive, and complicated projects

26. Differentiate between Empire Building and Garbage Can Model. (5)

Empire Building:

Empire building is a business term that refers to a common problem in larger organizations, in

which managers attempt to gather more administrative and financial power. Power can only be

shared in an organization with key employees in terms of their responsibilities & functions. Such

employees are the key players in the decision making process. Hence decisions taken in an

organization are a result of collective efforts of the leaders involved. This model is also termed

as Political Model.

.

Garbage Can Model:

This model states that organizations are not rational. Decisions made are largely on accidental

basis. Hence wrong solutions may be applied to wrong problems in an organization and critical

mistakes may occur. Information systems should be designed to support and assist in relevant

decision making, instead of making unrelated and wrong decisions. Page#76

Discuss System Analysis in the light of the following points:

1. A technique to map the system under study.

2. To drill down into the various aspects of the business process without losing sight of the

complete system.

System Analysis

System analysis can be defined simply as: “The study of business problem domain to

recommend improvements and specify the business requirements for the solution.”

Or alternatively as:

“A problem solving technique that decomposes a system into its component pieces for the

purpose of studying, how well those component parts work and interact to accomplish their

purpose.”

Both the definitions highlight following important points:

· System analysis helps to create an understanding of the business processes, their linkage with

one another, the parameters governing the data flow within the business, the controls and

checks built into the processes and the reporting needs in a business where a problem exists

or for which the software needs to be designed.

· System analysis creates the understanding and lays out the necessary relationships that will

.

assist in defining a solution to the problem or the design of the proposed software that will

meet the user needs. These two points may be understood as providing a means for undertaking

the following tasks:

· A technique to map the system under study.

· To drill down into the various aspects of the business process without losing sight of the

complete system.

· To understand the Workability/Functionality of the subsystems and their role in achieving the

objectives of the system as well as controls and checks in place.

· To establish the relationship or Level of interaction of each system with other components of

the system. Page 102

What will be the results if we compare Incremental models with Iterative Models?

Explain with any example

Incremental Models

In incremental models, software is built not written. Software is constructed step by step in

the same way a building is constructed. The products is designed, implemented, integrated

and tested as a series of incremental builds, where a build consists of code pieces from

various modules interacting together to provide a specific functional capability and testable

as a whole.

Iterative Models

.

In these models customer feed back is taken at each phase and project is modified accordingly – if

need be. Prototypes are used in these models

Question No: 22 ( Marks: 10 )

What are the components of the Expert System and how they are different from the neural

network?

There are four main components of Expert systems

· User Interface: to enable the manager to enter instructions and information into an

expert system to receive information from it.

· Knowledge Base: it is the database of the expert system. It contains rules to express the

logic of the problem.

· Inference engine: it is the database management system of the expert system. It performs

reasoning by using the contents of the knowledge base.

· Development engine – it is used to create an expert system.

Neural Network vs. Expert System

.

Expert systems seek to model a human expert’s way of solving problems. They are highly

specific to seeking solutions. Neural networks do not model human intelligence. They seek

to put intelligence into the hardware in the form of generalized capability to learn. Page#51

Semi Structured Decisions?

The term is used to refer to the grey area of decisions which lie between the two extremes.

Some (but not all) structured phases and often solved using standardized solution

procedures and human judgment. In small organizations decisions are usually transferred

from form top to bottom. In large organizations the decision are usually taken based on

meeting of all departmental heads. The fact is that whether decisions are taken by single

person or all in a formal meeting is not the sole determinant of a decision being structured

or unstructured. Rather it simply shows the complexity of the problem. Page#71
