HPH System Reliability Concepts by Dr. V. Sankar

System approach of modeling and analysis has been gaining much importance over the past few decades. Systems Society of India has also been initiated long back and the author is also a member of the society.

The author has done his research work in the area of system reliability applications to power system networks. He has the opportunity to extend the work various other fields of applications like, Industrial Engineering, Computer Science, Transportations problems, etc.

In industrial engineering problems, maximal-flow minimal cut theorem has been used which is based on the cutsets of networks. Cutsets are extensively used in developing theories of electrical circuit analysis initially. Cutsets are also useful in system analysis of probability of failure. Further, major advantages of cutset approach is that they directly represent the failure modes of the systems. Thus, not only systems can be analysed using cutset, criticality analysis can also be dealt with.

Graph theory, although, it can be stated to have been originated from electrical circuits, now it is a specialized topic in computer science field. Systems also can be classified as non-graph and graph systems essentially. Thus, Graph theoretic concepts can be applied to system reliability analysis wherein electrical, electronic and computer networks can be representable by graph systems.

Further, system reliability analysis will be based on the statistical data of its components from which probability distributions have been derived in the literature, i.e., the subject deals with essentially on fundamental concepts keeping the applications in mind. The applications will be system-oriented with respect to specific nature of the system that is under consideration.
