Fundamentals of matrix-analytic methods / Qi-Ming He. (OCLC #829754638)
The preface of this book was incredibly helpful in assigning the call number. The copy in OCLC already had a subject assigned (“Matrix analytic methods”) but needed a full call number. I did a correlations search in Classification Web which gave the class number QA274.2, which corresponds to “Stochastic analysis”, a broader term of “Matrix analytic methods”. So is that the right class number?
The preface of the book has a nice section called “Topics and organization of the book” which lists the broad topics of each chapter, including Poisson processes, Markov chains, and Queuing theory, all of which are narrower terms of “Stochastic processes” (a broader term “Stochastic analysis” even). I went with the broader class number, QA274, and added a few more subject headings for the other topics covered in depth.
QA274.2 may not seem far from QA274, but in my library, there would be about 100 books between them!
