Investigations on reliability evaluation Of component based software systems

Software Component plays a predominant role in our day to day life newlineHome appliances medical diagnostic devices automated teller machines newlineAircrafts automobiles and mobile phones etc are some examples where the newlinesoftware occupies a significant place Major business and financial transactions newlineare performed through on line with the aid of software systems A small fault in newlinethe software component results in the failure of entire software system that newlineleads to catastrophic failures on the activities of organization The minimal newlinecause of failure in the software component used in medical diagnostic devices newlineaircraft control systems and automobiles even claim the human lives The newlinefinancial software application halts with an error results in losses to the entire newlinebusiness Software reliability concepts are aimed at reducing these failures of newlinesoftware systems newlineComponent Based Software Engineering has now become a more newlinewidespread methodology for development of software systems The advantages newlineof this approach are minimized cost efforts and reduction in time consumption newlineThey are mainly because of pre defined software components Still ensuring a newlinereliable component based software system is difficult even with the use of pretested newlineand trusted software components Hence the reliability evaluation of newlinecomponent based software systems is essential in the present scenario of newlinesoftware usage newline newline
