This note from Prof. Vargas regarding a competitive title by Prof. Saaty with an almost identical title (THEORY AND APPLICATIONS OF THE ANALYTIC NETWORK PROCESS: Decision Making with Benefits, Opportunities, Costs, and Risks. RWS Publications, 2005):

The other book is theoretical with passing mention of examples to show how the subject is used. In our book (the one you have) the applications are different and given in full detail relevance and originality. They have never appeared in print as they are here and most users would prefer them to the theoretical book. In addition chapter 1 summarizes the theory given in four chapters on the book showing the important parts without going into too much detail. I would rather read this book than the other one definitely and this could not have been done so elegantly had not the other been written before. Therefore this book has the cream of the ideas and the best published applications so far.
