In solving real life assignment problem we often face the state of uncertainty as well as hesitation due to various uncontrollable factors. To deal with uncertainty and hesitation many authors have suggested the intuitionistic fuzzy representations for the data. So, in this paper, the authors consider the assignment problem having uncertainty and hesitation in cost/time/profit. They formulate the problem and utilize triangular intuitionistic fuzzy numbers (TIFNs) to deal with uncertainty and hesitation. The authors propose a new method called PSK (P.Senthil Kumar) method for finding the intuitionistic fuzzy optimal cost/time/profit for fully intuitionistic fuzzy assignment problem (FIFAP). The proposed method gives the optimal object value in terms of TIFN. The main advantage of this method is computationally very simple, easy to understand. Finally the effectiveness of the proposed method is illustrated by means of a numerical example which is followed by graphical representation of the finding.

(2004) proposed an efficient algorithm based on a labeling method for solving the linear fractional
programming case. Singh (2012) discussed note on assignment algorithm with easy method of
drawing lines to cover all zeros.
However,inreallifesituations,theparameterofassignmentproblemisinimpreciseinsteadof
fixedrealnumbersbecausetime/cost/profitfordoingajobbyafacility(machine/person)mightvary
duetodifferentreasons.Todealquantitativelywithimpreciseinformationinmakingdecision,Zadeh
(1965) introduced the fuzzy set theory and has applied it successfully in various fields. The use of
fuzzy set theory becomes very rapid in the field of optimization after the pioneering work done by
BellmanandZadeh(1970).Thefuzzysetdealswiththedegreeofmembership(belongingness)ofan
elementinthesetbutitdoesnotconsiderthenon-membership(non-belongingness)ofanelementin
theset.Inafuzzyset,themembershipvalue(levelofacceptanceorlevelofsatisfaction)liesbetween
0and1whereasincrispsettheelementbelongstothesetthatrepresents1andtheelementnotin
the set that represents 0.
Therefore the applications of fuzzy set theory enabled many authors to solve assignment,
transportationandlinearprogrammingproblemsbyusingfuzzyrepresentationfordata.Kumaret
al. (2009) proposed a method for solving fully fuzzy assignment problems using triangular fuzzy
numbers.MukherjeeandBasu(2010)presentedanapplicationoffuzzyrankingmethodforsolving
assignmentproblemswithfuzzycosts.KumarandGupta(2012)investigatedassignmentandtravelling
salesman problems with cost coefficients as LR fuzzy parameters. De and Yadav (2012) evolved a
general approach for solving assignment problems involving with fuzzy costs coefficients.Thorani
and Shankar (2013) did fuzzy assignment problem with generalized fuzzy numbers. Kumar and
Kaur (2011) presented methods for solving fully fuzzy transportation problems based on classical
transportationmethods.Ebrahimnejadetal.(2011)proposedboundedprimalsimplexalgorithmfor
bounded linear programming with fuzzy cost coefficients. Nasseri and Ebrahimnejad (2011) did
sensitivityanalysisonlinearprogrammingproblemswithtrapezoidalfuzzyvariables.Pattnaik(2015)
presenteddecisionmakingapproachtofuzzylinearprogrammingproblemswithpostoptimalanalysis.
Intheassignmentproblem,theperformingtimeofeachjobtotheworkersisnotknownexactly.
This may be due to lack of experience, interest, capacity, understanding, etc. In such situation the
DM cannot predict performing time exactly. Hence the decision maker may hesitate.The fuzzy set
dealswiththebelongingnessofanelementinthesetbutitdoesnotconsiderthenon-belongingness
(rejectionslevel)ofanelementintheset.So,tocountertheseuncertaintieswithhesitation,Atanassov
(1983) proposed the intuitionistic fuzzy set (IFS) which is more reliable than the fuzzy set proposed
by Zadeh (1965).The major advantage of intuitionistic fuzzy set over fuzzy set is that IFS separates
thedegreeofmembership(belongingness)andthedegreeofnonmembership(nonbelongingness)
ofanelementintheset.WiththehelpofIFStheory,decisionmakercandecideaboutthedegreeof
acceptance,degreeofnonacceptanceanddegreeofhesitationforsomequantity.Incaseofassignment
problem,theDMcandecideaboutthelevelofacceptanceandnon-acceptancefortheassignment
cost/profit/time.Duetothis,theapplicationofIFStheorybecomesverypopularinprojectschedules,
transportation problems, decision making theory and network flow problems etc.
In literature, due to the lack of uncertainty of the parameter of the fuzzy assignment problem,
many authors have solved assignment problem with intuitionistic fuzzy version. Mukherjee and
Basu (2012) presented the solution of a class of intuitionistic fuzzy assignment problem by using
similarity measures. Jose and Kuriakose (2013) discussed algorithm for solving an assignment
model in intuitionistic fuzzy context. Kumar and Hussain (2014) presented a method for finding an
optimalsolutionofanassignmentproblemundermixedintuitionisticfuzzyenvironment.Kumarand
Bajaj (2014) evolved on solution of interval valued intuitionistic fuzzy assignment problem using
similaritymeasureandscorefunction.KumarandHussain(2014)didamethodforsolvingbalanced
