ISBN 981-256-076-9 Printed by Multiprint Services Preface Fuzzy relations appear as a natural generalization of crisp relations. While a crisp relation determines the presence or absence of interconnectedness between the elements of two or more sets, fuzzy relations supply additional information for degrees of membership, strengths of associations, i
