Real Time System Fault Tolerance Scheduling Algorithms

The main objective of this paper is to implement the real time scheduling algorithms and discuss the advantages and disadvantages of the same..I am compare the scheduling algorithm in which tasks execute.in this no efficient scheduling algorithms exit for optimal solution..I am trying to solve this problem by taking new algorithm i.e. with shortest (Arrival time + completion time) is considered and implemented on single processor I am using assumptions and some terminology, this algorithm is based on preemption.
