At the outset the book gives most of the available literature about Fuzzy Relational Equations (FREs) and its properties for there is no book that solely caters to FREs and its applications. Though we have a comprehensive bibliography, we do not promise to give all the possible available literature about FRE and its applications. We have given only those papers which we could access and which interested us specially. We have taken those papers which in our opinion could be transformed for neutrosophic study. The second importance of this book is that for the first time we introduce the notion of Neutrosophic Relational Equations (NRE) which are analogous structure of FREs. Neutrosophic Relational Equations have a role to play for we see that in most of the real-world problems, the concept of indeterminacy certainly has its say; but the FRE has no power to deal with indeterminacy, but this new tool NRE has the capacity to include the notion of indeterminacy. So we feel the NREs are better tools than FREs to use when the problem under investigation has indeterminates. Thus we have defined in this book NREs and just sketched its probable applications. This book has five chapters. The first chapter is a bulky one with 28 sections. These sections deal solely with FREs and their properties. By no means do we venture to give any proof for the results for this would make our book unwieldy and enormous in size. For proofs, one can refer the papers that have been cited in the bibliography. The second chapter deals with the applications of FRE. This has 10 sections: we elaborately give the applications of FRE in flow rates in chemical industry problems, preference and determination of peak hour in the transportation problems, the social problems faced by bonded laborers etc. Chapter three for the first time defines several new neutrosophic concepts starting from the notion of neutrosophic fuzzy set, neutrosophic fuzzy matrix, neutrosophic lattices, neutrosophic norms etc. and just indicate some of its important analogous properties. This chapter has six sections which are solely devoted to the introduction of several neutrosophic concepts which are essential for the further study of NRE. 7 Chapter four has eleven sections. This chapter gives all basic notions and definitions about the NREs and introduces NREs. Section 4.11 is completely devoted to suggest how one can apply NREs in the study of real world problems. We suggest many problems in chapter five for the reader to solve. This is the third book in the Neutrosophics Series. The earlier two books are Fuzzy Cognitive Maps and Neutrosophic Cognitive Maps (http://gallup.unm.edu/~smarandache/NCMs.pdf) and Analysis of Social Aspects of Migrant Labourers Living With HIV/AIDS Using Fuzzy Theory and Neutrosophic Cognitive Maps: With Specific Reference to Rural Tamil Nadu in India (http://gallup.unm.edu/~smarandache/NeutrosophyAIDS.pdf). Finally, we thank Meena Kandasamy for the cover design. We thank Kama Kandasamy for the layout of the book and for drawing all the figures used in this book. She displayed an enormous patience that is worthy of praise. We owe deep thanks to Dr.K.Kandasamy for his patient proof-reading of the book. Without his help this book would not have been possible.
