The first page of Contents of this pdf file: http://fisher.stat.wmich.edu/joe/Stat666/book/book.pdf # which bears your advisor's name as co-author and is presumably sitting on his website ...has an entry: 1.9 Ranked Set Sampling . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 53 And there VERY DEFINITELY IS a 4 page section that bears that title in the body of the text.
