The K-2 Tower 8611 meters in the Karakorum range of

the western Himalayas 2ndHighest peak and considered most

difficult to climb (success rate less than

40%) An expedition to K-2 typically lasts several

months

Lot of planning and efforts

Many unexpected events may happen.

NAS Monitors and controls air-traffic in US

More than 18,300 airport, 21 air route traffic control centers,460 control towers

More than 34000 pieces of equipments - radar systems,

communication switches, radios, computer systems, displays

Computers at 21 air route traffic control centers are IBM 3083mainframes

In 1996, US Govt initiated a modernization program thatincluded satellite navigation, digital communications,

automation, decision support system, etc

A previous similar effort (AAS) was suspended in 1994

because of software failure

Engineering of Complex Systems Complex systems many components and

interactions External conditions can trigger unexpected changes

The problem is beyond the control of any single

individual Changes forces participants to look for new

solutions

Several participant need to cooperate and developdesired solution

We are interested in Software-IntensiveSystems

Writing Programs Dos ! You choosea programming language

You write everythingfrom scratch For you, writing program means mainly

coding

You do some testingto show that it works (adhoc)

You decide to stop coding (ad hoc)

You show/submit it to your teacher

Thats All !

How the Course Fits into CSCurriculum?

Most courses for learning technology

Compilers, operating systems, databases, etc.

This course concerns wrt. analysis, design,implementation, testing, and maintenance ofSoftware Systems Assume you can program/learn new languages

Make use of technology as a tool to support

process Skills will become very important upon graduation

complex systems, large teams

dont look for large immediate impact in other CS courses
