Mathematical modeling is a field of interest to various researchers working in various disciplines of Mathematical, Social, Psychological, Environmental, and Life Sciences. These mathematical models deal with both types of uncertainties arising on account of probabilistic as well as fuzzy distributions and find tremendous applications to a variety of disciplines. Keeping in view the idea, we have developed many uncertain models dealing with probability distributions and fuzzy distributions. The present book is basically concerned with the study of entropy function which is a notion of...
