From the reviews: "This book has four objectives: to give newcomers a clear idea ... to give people familiar with fuzzy logic an indication of where fuzzy logic can most effectively proceed, to give funding agencies a picture of where their investment would produce maximum returns, and to give scientific and mathematical philosophers a picture of the state-of-the-art in fuzzy logic research. ... This comprehensive, up-to-date book certainly deserves a place in the libraries of all institutions ... . Summing Up: Recommended. Upper-division undergraduates through professionals." (R. Bharath, CHOICE, Vol. 45 (7), 2008)
