Foreword
Fuzzydecisionandgametheoryhavebeenextensivelystudiedandachievedgreat
success in the last two or three decades. The fuzzy set theory introduced by
L. A. Zadeh in 1965 is an important tool to deal with fuzziness appearing in
management decision and game problems. The concept of fuzzy sets is a cor-
nerstoneofthefuzzysettheory.Zadehusedsingleindex(i.e.,membershipdegree
or function) to define the fuzzy set. Namely, the single membership degree (or
function) was used to express two opposite aspects (or states) offuzziness, fuzzy
concept,and/orfuzzyphenomenasimultaneously.Inotherwords,Zadehusedonly
a membership function, which assigns to each element x of the universe of dis-
course a real number lðxÞ from the unit interval [0, 1] to indicate the degree of
belongingness to the fuzzy set under consideration. The degree of nonbelong-
ingness is just automatically equal to 1(cid:2)lðxÞ. Thus, the fuzzy set is not able to
express the neutral state, i.e., neither supporting nor opposing. That is to say, the
fuzzysetisonlyabletodescribefuzzinessof‘‘thisandalsothat.’’Thelimitofthe
concept offuzzy sets brings forward new research topics and challenges in com-
plexmanagementsituations.Inreality,however,ahumanbeingwhoexpressesthe
membership degree of a given element in a fuzzy set very often does not express
corresponding nonmembership degree as the complement to 1. As a result,
K. T. Atanassov in 1983 introduced the concept of an intuitionistic fuzzy set,
which is characterized by two functions expressing the degree of belongingness
and the degree of nonbelongingness, respectively. The intuitionistic fuzzy set has
two indices (i.e., membership and nonmembership degrees or functions), which
can be used to express three states of fuzzy concepts and/or fuzzy phenomena:
support, opposition, and neutrality. Namely, the intuitionistic fuzzy set is able to
describe fuzziness of ‘‘neither this nor that.’’ So far as I know, however, there is
less investigation on decision and games with intuitionistic fuzzy sets.
Decisionandgameswithintuitionisticfuzzysetsareremarkablydifferentfrom
fuzzy decision and games. The reason is that the former uses the intuitionistic
fuzzy set with two indices to describe fuzziness in actual decision and game
problems, whereas the latter uses the fuzzy set with single index to handle fuzz-
iness. On the other hand, in decision and games with intuitionistic fuzzy sets the
mutual conflicting two indices (i.e., the vector consisting of membership and
nonmembership degrees or functions) have to be compared, whereas in fuzzy
decision and games only single index (i.e., membership degree or function) is

compared. As a result, the models and methods of fuzzy decision and games
cannot be straightforwardly extended to decision and games with intuitionistic
fuzzy sets. Therefore, we need to establish a new system of theories and methods
for decision andgames withintuitionistic fuzzysets,which naturally includes the
systemoftheoriesandmethodsforfuzzydecisionandgames.Inotherwords,the
latterisaspecialcaseoftheformer.Thus,wemaybelievethatdecisionandgames
with intuitionistic fuzzy sets are an extension and a perfection offuzzy decision
and games.

50 papers published in international famous journals by myself and co-authors in
recent years. The intuitionistic fuzzy set is used to describe and expressfuzziness
appearing in real decision and game problems, especially hesitancy degree in
judgmentanddecisionprocessofdecisionmaker(s)orplayer(s).1Payingattention
to such a decision factor is one of the salient signs in which modern decision
science differs from Bayes statistic decision. This book includes two closely rel-
ativepartsofdecisionandgameswithintuitionisticfuzzysets.Itisdividedinto11
chapters. Chapter 1 mainly describes the concept of intuitionistic fuzzy sets and
operations, distances and similarity degrees between intuitionistic fuzzy sets,
representation theorems and extension principles of intuitionistic fuzzy sets,
definitions of trapezoidal intuitionistic fuzzy numbers and triangular intuitionistic
fuzzy numbers as well as algebraic operations. Chapter 2 mainly expatiates
the intuitionistic fuzzy weighted averaging operator, the intuitionistic fuzzy
ordered weighted averaging (OWA) operator, the intuitionistic fuzzy hybrid
weighted averaging operator, and the intuitionistic fuzzy generalized
hybrid weighted averaging operator as well as the intuitionistic fuzzy generalized
hybrid weighted averaging method of multiattribute decision-making with intui-
tionisticfuzzysets.Chapter 3isdevotedtothelinear weighted averagingmethod

solution and weights unknown as well as the fraction mathematical programming
method and the linear programming method for intuitionistic fuzzy multiattribute
decision-making with intuitionistic fuzzy weights unknown. Chapter 4 mainly
discusses the interval-valued intuitionistic fuzzy continuous ordered weighted
averaging (COWA) operator, the interval-valued intuitionistic fuzzy generalized
hybrid weighted averaging operator, the interval-valued intuitionistic fuzzy con-
tinuous hybrid weighted averaging operator and the multiattribute decision-mak-
