Proecton easure s a useful apparatus for odelng real lfe decson akng probles. n the paper we have defned proecton bdrectonal proecton and hybrd proecton easures between bpolar neutrosophc sets and the proposed easures are then appled to ult-attrbute decson akng probles. he ratngs of perforance values of the alternatves wth respect to the attrbutes are epressed by bpolar neutrosophc values. We calculate proecton bdrectonal proecton and hybrd proecton easures between each alternatve and deal alternatve wth bpolar neutrosophc nforaton and then all the alternatves are ranked to dentfy best opton. nally a nuercal eaple s provded to deonstrate the applcablty and effectveness of the developed ethod. Coparson analyss wth other estng ethods s also provded.

Later Wang et al. [] proposed sngle valued neutrosophc sets VNs to deal real decson akng probles where le n [0 ]. n 994 Zhang [3] [4] grounded the noton of bpolar fuy sets by etendng the concept of fuy sets. he value of ebershp degree of an eleent of bpolar fuy set belongs to [- ]. Wth reference to a bpolar fuy set the ebershp degree ero of an eleent reflects that the eleent s rrelevant to the correspondng property the ebershp degree belongs to 0] of an eleent reflects that the eleent soewhat satsfes the property and the ebershp degree belongs to [ 0 of an eleent reflects that the eleent soewhat satsfes the plct counter-property.
2 Del et al. [5] ntroduced the concept of bpolar neutrosophc sets BNs by cobnng the concept of bpolar fuy sets and neutrosophc sets. Wth reference to a bpolar neutrosophc set the postve ebershp degrees represent respectvely the truth ebershp ndeternate ebershp and falsty ebershp of an eleent X correspondng to the bpolar neutrosophc set and the negatve ebershp degree denotes the truth ebershp ndeternate ebershp and false ebershp of an eleent X to soe plct counter-property correspondng to the bpolar neutrosophc set. Proecton easure s a useful decson akng devce as t takes nto account the dstance as well as the ncluded angle for easurng the closeness degree between two obects [6 7]. Yue [6] and Zhang et al. [7] studed proecton based ult attrbute decson akng n crsp envronent.e. proectons are defned on ordnary nubers or crsp nubers. Yue [8] further nvestgated a new ult attrbute group decson akng MAGDM ethod based on deternng the weghts of the decson akers by eployng proecton technque wth nterval data. Yue and Ja [9] establshed a ethodology for MAGDM based on a new noraled proecton easure n whch the attrbute values are provded by decson akers n hybrd for wth crsp values and nterval data. Xu and Da [0] and Xu [] studed proecton ethod for decson akng n uncertan envronent wth preference nforaton. We [] dscussed a ult attrbute decson akng MADM ethod based on the proecton technque n whch the attrbute values are presented n ters of ntutonstc fuy nubers. Zhang et al. [3] proposed a grey relatonal proecton ethod for MADM based on ntutonstc trapeodal fuy nuber. Zeng et al. [4] nvestgated proectons on nterval valued ntutonstc fuy nubers and we developed odel and algorth to the MAGDM probles wth nterval-valued ntutonstc fuy nforaton. Xu and Hu [5] developed two proecton based odels for MADM n ntutonstc fuy envronent and nterval valued ntutonstc fuy envronent. un [6] presented a group decson akng ethod based on proecton ethod and score functon under nterval valued ntutonstc fuy envronent. sao and Chen [7] developed a novel proecton based coprosng ethod for ult crtera decson akng ethod n nterval valued ntutonstc fuy envronent. n neutrosophc envronent Chen and Ye [8] developed proecton based odel of neutrosophc nubers and presented MADM ethod to select clay-brcks n constructon feld. Bdrectonal proecton easure [9] consders the dstance and ncluded angle between two vectors y and also consders the bdrectonal proecton easure between two vectors y. Ye [9] defned bdrectonal proecton easure as an proveent of the general proecton easure of VNs to overcoe the drawback of the general proecton easure. n the sae study Ye [9] developed ult attrbute decson akng ethod for selectng probles of echancal desgn schees under a sngle-valued neutrosophc envronent. Ye [0] also presented bdrectonal proecton ethod for ultple attrbute group decson akng wth neutrosophc nubers.
3 Ye [] defned credblty nduced nterval neutrosophc weghted arthetc averagng operator and credblty nduced nterval neutrosophc weghted geoetrc averagng operator and developed the proecton easure based rankng ethod for ult-attrbute decson akng MADM probles wth nterval neutrosophc nforaton and credblty nforaton. Dey et al. [] proposed a new approach to neutrosophc soft MADM usng grey relatonal proecton ethod. Dey et al. [3] defned weghted proecton easure wth nterval neutrosophc assessents and appled the proposed concept to solve MADM probles wth nterval valued neutrosophc nforaton. n the feld of bpolar neutrosophc envronent Del et al. [5] defned score accuracy and certanty functons n order to copare BNs and developed bpolar neutrosophc weghted average BNWA and bpolar neutrosophc weghted geoetrc BNWG operators to obtan collectve bpolar neutrosophc nforaton. n the sae study Del et al. [5] also proposed a ult-crtera decson akng MCDM approach on the bass of score accuracy and certanty functons and BNWA BNWG operators. Del and ubas [4] presented a sngle valued bpolar neutrosophc MCDM through correlaton coeffcent slarty easure. Şahn et al. [5] provded a MCDM ethod based on Jaccard slarty easure of BN. Uluçay et al. [6] defned Dce slarty weghted Dce slarty hybrd vector slarty weghted hybrd vector slarty easures under BNs and developed MCDM ethods based on the proposed slarty easures. Dey et al. [7] defned Hang and Eucldean dstance easures to copute the dstance between BNs and nvestgated a OP approach to derve the ost desrable alternatve. n ths study we defne proecton bdrectonal proecton and hybrd proecton easures under bpolar neutrosophc nforaton. hen we develop three algorths for solvng MADM probles wth bpolar neutrosophc assessents. We organe the rest of the paper n the followng way. n ecton we recall several useful defntons concernng VNs and BNs. ecton 3 defnes proecton bdrectonal proecton and hybrd proecton easures between BNs. ecton 4 s devoted to present three odels for solvng MADM under bpolar neutrosophc envronent. n ecton 5 we solve a decson akng proble wth bpolar neutrosophc nforaton on the bass of the proposed easures.

Defnton 6. Consder X = be a fnte unverse of dscourse and be a BN n X then odulus of s defned as follows: = α = [ where α = =. Defnton 7 [0 8]. Consder u = u u u and v = v v v be two vectors then the proecton of vector u onto vector v can be defned as follows: ]

Consder X = be a fnte unverse of dscourse and be two BNs n X then Pro = Cos =. s called the proecton of on where = ] [ = ] [ and. =. ] [ Eaple. = < > = < > be two BNs n X then the proecton of on s obtaned as follows: Pro =. = = he bgger value of Pro reflects that and are closer to each other. However n sngle valued neutrosophc envronent Ye [0] observed that for two vectors and the general proecton easure cannot descrbe accurately the degree of close to. We also notce that the general proecton ncorporated by Xu [] s not reasonable n several cases under bpolar neutrosophc settng for eaple let = = < a a a -a -a -a > and = < a a a -a -a -a > then Pro = a and Pro = a. hs shows that s uch closer to than whch s not true because =. Ye [0] opned that s equal to whenever Pro and Pro should be equal to. herefore Ye [0] proposed an alternatve ethod called bdrectonal proecton easure to overcoe the ltaton of general proecton easure as gven below. Defnton 9 [0]. Consder and y be two vectors then the bdrectonal proecton between and y s defned as follows: B-pro y =.. y y y = y y y y.

Consder = and = be two BNs n X = then the bdrectonal proecton easure between and s defned as follows: B-Pro =.. =. where = = [ ] [ ] and [. = ] Proposton. Let B-Pro be a bdrectonal proecton easure between BNs and then we have. 0 B-Pro ;. B-Pro = B-Pro ; 3. B-Pro = for =. Proof..

Let = and = be two BNs n X = then the hybrd proecton easure s defned as the cobnaton of proecton easure and bdrectonal proecton easure. he hybrd proecton easure between and s represented as follows: Hyb-Pro = Pro + - B-Pro = where = ] [ = ] [ and. = ] [ where 0. Eaple 3. Assue that = < > = < > be two BNs n the unverse of dscourse X then the hybrd proecton easure between on wth = 0.7 s calculated as gven below. Hyb-Pro = = Proecton b-drectonal proecton and hybrd proecton based decson akng ethods for MADM probles wth bpolar neutrosophc nforaton n ths ecton we develop proecton based decson akng odels to MADM probles wth bpolar neutrosophc assessents. Consder E = {E E E } be a dscrete set of feasble alternatves = { n} n be a set of attrbutes under consderaton and w = w w w n be the weght vector of the attrbutes such that 0 w and n w =.

Coparatve analyss n the ecton we copare the results obtaned fro the proposed ethods wth the results derved fro other estng ethods under bpolar neutrosophc envronent to show the effectveness of the developed ethods. Dey et al. [7] assue that the weghts of the attrbutes are not dentcal and weghts are fully unknown to the decson aker. Dey et al. [7] forulated ang devaton odel under bpolar neutrosophc assessent to copute unknown weghts of the attrbutes as w = By consderng w = the proposed proecton easure are shown as follows: Pro 4 Z P Z P = nce Pro = Pro Z P Z P > Pro Z P 3 = Pro Z P 4 > Pro Z P 3 > Pro Z P = 3.65 Pro therefore the rankng order of the four alternatves s gven by E E E 4 E 3. hus E s the best choce for the custoer.

[5] assue the weght vector of the attrbutes as w = and the rankng order based on score values s presented as follows: E 3 E 4 E E hus E 3 was the ost desrable alternatve. Dey et al. [7] eployed ang devaton ethod to fnd unknown attrbute weghts as w = he rankng order of the alternatves s presented based on the relatve closeness coeffcent as gven below. E 3 E E 4 E Obvously E 3 was the ost sutable opton for the custoer.
16 Dey et al. [7] also consder the weght vector of the attrbutes as w = then by usng OP ethod the rankng order of the cars s represented as follows: E 4 E E 3 E. o E 4 would be the ost preferable alternatve for the buyer. We observe that dfferent proecton easures provde dfferent rankng results and the proecton easure s weght senstve. herefore decson aker should choose the proecton easure and weghts of the attrbutes n the decson akng contet accordng to hs/her needs desres and practcal condton 7. Concluson n ths paper we have defned proecton bdrectonal proecton easures between bpolar neutrosophc sets. urther we have defned a hybrd proecton easure by cobnng proecton and bdrectonal proecton easures. hrough these proecton easures we have developed three algorths for ult-attrbute decson akng odels under bpolar neutrosophc envronent for choosng the best alternatve. nally a car selecton proble has been provded to show the fleblty and applcablty of the proposed ethods. urtherore coparson analyss of the proposed ethods wth the other estng ethods has also been deonstrated. he proposed algorths can be etended to nterval bpolar neutrosophc envronent. n future we shall apply proecton bdrectonal proecton and hybrd proecton easures of nterval bpolar neutrosophc sets for group decson akng edcal dagnoss weaver selecton pattern recognton probles. e f e r e n c e s. arandache.
