Cha E-mal: weguwu@63.com Receved 8 Aprl 206; accepted 3 May 206 Abstract. I ths paper, we vestgate the multple attrbute decso makg problems wth pcture fuzzy formato. The advatage of pcture fuzzy set s easly reflectg the ambguous ature of subectve udgmets because the pcture fuzzy sets are sutable for capturg mprecse, ucerta, ad cosstet formato the multple attrbute decso makg aalyss. Thus, the cross etropy of pcture fuzzy sets, called pcture fuzzy cross etropy, s proposed as a exteso of the cross etropy of fuzzy sets. The, a multple attrbute decso makg method based o the proposed pcture fuzzy cross etropy s establshed whch attrbute values for alteratves are pcture fuzzy umbers. I decso makg process, we utlze the pcture fuzzy weghted cross etropy betwee the deal alteratve ad a alteratve to rak the alteratves correspodg to the cross etropy values ad to select the most desrable oe(s). Fally, a practcal example for eterprse resource plag system selecto s gve to verfy the developed approach ad to demostrate ts practcalty ad effectveess.

Itroducto Etropy s very mportat ad effectve tool for measurg ucerta formato. Frstly, Zadeh (965, 968) troduced the fuzzy etropy. The startg pot for the crossetropy approach s formato theory as developed by Shao (948). Kullback ad Lebler (95) proposed the cross-etropy dstace measure betwee two probablty dstrbutos. Later, L (99) proposed a modfed cross-etropy measure. Shag ad Jag (997) proposed a fuzzy cross-etropy measure ad a symmetrc dscrmato formato measure betwee fuzzy sets. Vlachos ad Sergads (2007) developed the tutostc fuzzy cross-etropy based o the De Luca-Term o-probablstc etropy (Deluca, Feru 972). Zhag ad Jag (2008) defed the cross-etropy betwee vague sets. Accordg to the cross-etropy of vague sets, Ye (2009a) has vestgated the fault dagoss problem of turbe.

Ye (20) proposed a tervalvalued tutostc fuzzy cross-etropy for multple attrbute decso makg problems o the bass of the vague cross-etropy. Xa ad Xu (202) proposed some cross-etropy ad etropy formulas for tutostc fuzzy sets ad appled them to group decsomakg. For terval-valued tutostc fuzzy sets, Zhag ad Jag (200) proposed the etropy ad cross-etropy cocepts ad dscussed the coectos amog some mportat formato measures. Xu ad Xa (202) troduced the cocepts of etropy ad cross-etropy for hestat fuzzy formato, ad dscuss ther desrable propertes. Recetly, Cuog (203) proposed pcture fuzzy set (PFS) ad vestgated the some basc operatos ad propertes of PFS. The pcture fuzzy set s characterzed by three fuctos expressg the degree of membershp, the degree of eutral membershp ad the degree of o-membershp. The oly costrat s that the sum of the three degrees must ot exceed. Bascally, PFS based models ca be appled to stuatos requrg huma opos volvg more aswers of types: yes, absta, o, refusal, whch ca t be accurately expressed the tradtoal FS ad IFS. Utl ow, some progress has bee made the research of the PFS theory. Sgh (204) vestgated the correlato coeffcets for pcture fuzzy set ad apply the correlato coeffcet to clusterg aalyss wth pcture fuzzy formato. So (205) ad Thog ad So (205) troduced several ovel fuzzy clusterg algorthms o the bass of pcture fuzzy sets ad applcatos to tme seres forecastg ad weather forecastg. Thog (205) developed a ovel hybrd model betwee pcture fuzzy clusterg ad tutostc fuzzy recommeder systems for medcal dagoss ad applcato to health care support systems. Due to the advatage of pcture fuzzy set s easly reflectg the ambguous ature of subectve udgmets because the pcture fuzzy sets are sutable for capturg mprecse, ucerta, ad cosstet formato actual multple attrbute decso makg aalyss as metoed above, t s ecessary to develop some cross-etropy measures for pcture fuzzy set. I order to do so, the remader of ths paper s set out as follows. I the ext secto, we troduce some basc cocepts related to tutostc fuzzy set ad pcture fuzzy sets. I Secto 2, we shall propose the pcture fuzzy cross-etropy ad pcture fuzzy weghted cross-etropy. I Secto 3, based o pcture fuzzy weghted cross-etropy, we shall preset the model for multple attrbute decso makg problems wth pcture fuzzy formato. I Secto 4, we shall preset a umercal example for eterprse resource plag (ERP) system selecto wth pcture fuzzy formato order to llustrate the method proposed ths paper. The last secto cocludes the paper wth some remarks.. Prelmares I the followg, we troduce some basc cocepts related to tutostc fuzzy sets. Defto (Ataassov 986, 989). A IFS A X s gve by: = {, ma, A Î } where ma : X [ 0,] ad : [ 0,] A X, where, A A A x x x x X, () 0 m x x, xîx. The
3 umber m A ( x ) ad Joural of Busess Ecoomcs ad Maagemet, 206, 7(4): A x represets, respectvely, the membershp degree ad omembershp degree of the elemet x to the set A. The tutostc fuzzy sets have receved more ad more atteto sce ts appearace. Kosareva ad Krylovas (203) establshed the types of tutostc fuzzy umbers ad the expoet values of the geeralzed weghted averagg operator havg the least error probabltes cosderg alteratves rakg. Razav Haagha et al. (203) defed a complex proportoal assessmet method for group decso makg a terval-valued tutostc fuzzy evromet. Krohlg et al. (203) also exteded the tutostc fuzzy TODIM to mult-crtera decso makg. Che (204) proposed the terval-valued tutostc fuzzy QUALIFLEX method wth a lkelhood-based comparso approach for multple crtera decso aalyss. Lourezutt ad Krohlg (203) developed the TODIM method a tutostc fuzzy ad radom evromet. Wu et al. (203) researched o the AHP wth terval-valued tutostc fuzzy sets ad ts applcato mult-crtera decso makg problems. Zavadskas et al. (204) proposed the exteso of weghted aggregated sum product assessmet wth tervalvalued tutostc fuzzy umbers. Wag ad Lu (204) developed some hestat fuzzy geometrc operators for multple attrbute group decso makg. Razav Haagha et al. (205) evolved a lear programmg techque for MAGDM problems wth terval valued tutostc fuzzy formato. Wu (205) proposed a SD-IITFOWA operator ad TOPSIS based approach for MAGDM problems wth tutostc trapezodal fuzzy umbers. Abdullah ad Nab (206) developed a ew preferece scale MCDM method based o terval-valued tutostc fuzzy sets ad the aalytc herarchy process. Although, tutostc fuzzy set theory (Ataassov 986, 989) has bee successfully appled dfferet areas, but there are stuatos real lfe whch ca t be represeted by tutostc fuzzy sets. Pcture fuzzy sets are exteso of tutostc fuzzy sets. Pcture fuzzy set (Cuog 203) based models may be adequate stuatos whe we face huma opos volvg more aswers of types: yes, absta, o, refusal. It ca be cosdered as a powerful tool represet the ucerta formato the process of patters recogto ad cluster aalyss. Defto 2 (Cuog 203). A pcture fuzzy set (PFS) A o the uverse X s a obect of the form: x sat- x X, x x x x could be called the degree of refusal membershp of x A. Cuog (203) also defed some operatos as follows. {, A, A, A } where ma Î[ 0,] ha ( x ) Î[ 0,] s called the degree of eutral membershp of A ad A ( x ) Î [ 0, ] s called the degree of egatve membershp of A, ad m A ( x ), h A ( x ), A sfy the followg codto: 0 m A( x) h A( x) A( x ), xîx.

Cross-etropy betwee pcture fuzzy sets a a a I ths secto, we shall develop the cross-etropy ad dscrmato formato measures betwee two PFSs based o the exteso of the cocept of cross-etropy betwee two fuzzy sets. To do ths, we frstly troduce the cocepts of cross-etropy ad symmetrc dscrmato formato measures betwee two fuzzy sets whch were proposed by Shag ad Jag (997). Defto 4 (Shag, Jag 997). Assume that a= ( a( x), a( x2),, a( x )) ad b= ( b( x), b( x2),, b( x )) are two fuzzy sets the uverse of dscourse ( x, x2,, x ). The fuzzy cross-etropy of a from b s defed as follows: a a ( a, b ) = x x h a ( x) l ( a( x), (3) = ( a ( x ) b) ( a b) x x x whch dcates the degree of dscrmato of a from b. However, h( ab, ) s ot symmetrc wth respect to ts argumets. Shag ad Jag (997) proposed a symmetrc dscrmato formato measure: ( ab, ) = ( ab, ) ( ba, ) Moreover, there are I ( ab, ) 0ad ( ab, ) = 0 I h h. (4) I f ad oly f a = b. The, the cross-etropy ad symmetrc dscrmato formato measures betwee two fuzzy sets are exteded to these measures betwee PFSs. I order to do so, let us cosder two group of pcture fuzzy umbers a = ( m,, ) a h a a ad b= ( m,, ) b h b b, =, 2,,. Thus based o Eq. (3), the amout of formato for dscrmato of ma from m b ( =, 2,, ) ca be gve by: ma ma m C ( a, b, m ) =m a l ( ma, (5) ( m a mb ) ( m a m b ) 2 2,,
5 Joural of Busess Ecoomcs ad Maagemet, 206, 7(4): Therefore, the expected formato based o the sgle degree of postve membershp for dscrmato of a agast b s expressed by: C m ma m a a, b = m a l ( ma = ( m m ) m m a b a b. (6) Smlarly, cosderg the degree of eutral membershp ad the degree of egatve membershp, we have the followg amouts of formato: C C h ha h a a, b = h a l ( ha = ( h h ) h h a b a b va a a, b = a l ( a = ( ) a b a b ; (7). (8) Hece, a ovel pcture fuzzy cross-etropy measure betwee a ad b s obtaed as the sum of the three amouts: ma m a C ( a, b ) = m a l ( m a = ( m a mb ) ( m a mb ) ha h a h a l ( h a = ( h a hb ) ( h a hb ) = va a a l ( a ( ) a b a b, (9) whch also dcates dscrmato degree of a from b. Accordg to Shao s (948) equalty, oe ca easly prove that C ( ab, ) 0ad C ( ab, ) = 0f ad oly f a = b. The, C ( ab, ) s ot symmetrc. So t should be modfed to a symmetrc dscrmato formato measure for PFSs as: ( ab, ) = ( ab, ) ( ba, ) The larger the dfferece betwee a ad b s, the larger ( ab, ) D C C. (0) D s. 495
6 G. We. Pcture fuzzy cross-etropy for multple attrbute decso makg problems If we cosder the weghts of a ad b, a pcture fuzzy weghted cross-etropy measure betwee a ad b s proposed as follows: C m m a b = w m ( m ) a a w(, ) a l a l = m a mb m a m b = = ha h a w h a l ( h a ( h a hb ) ( h a hb ) va a w a l ( a ( ) a b a b, () where w= ( w, w,, w ) T s the weght vector of ab, ( =, 2,, ), wth w Î[ 0,] =, 2,,, 2 = w =,, whch also dcates dscrmato degree of a from b. Accordg to Shao s equalty (5), oe ca easly prove that C w ( ab, ) 0 ad C (, ) w ab = 0 f ad oly f a = b. The, C w ( ab, ) s ot symmetrc. So t should be modfed to a symmetrc dscrmato formato measure for PFSs as w( ab, ) = w( ab, ) w( ba, ) The larger the dfferece betwee a ad b s, the larger ( ab, ) D C C. (2) D s. 3. Models for multple attrbute decso makg based o cross-etropy wth pcture fuzzy formato Based o cross-etropy wth pcture fuzzy formato, ths secto, we shall propose the correspodg model for multple attrbute decso makg wth pcture fuzzy formato. Let A= { A, A2,, Am } be a dscrete set of alteratves, ad G = { G, G2,, G} be the set of attrbutes, w= ( w, w2,, w ) s the weghtg G =, 2,, w Î 0, w =. Suppose that vector of the attrbute ( ), where [ ] ( r ) (,, ) w, = R = = m h s the pcture fuzzy decso matrx, where m m m dcates the degree of postve membershp that the alteratve A satsfes the attrbute G gve by the decso maker, h dcates the degree of eutral membershp that the alteratve A does t satsfy the attrbute G, dcates the degree that the alteratve A does t satsfy the attrbute G gve by the decso maker, m Î[ 0,], h Î[ 0,], Î[ 0,] m h, π = ( m h ) =, 2,, m, =, 2,,., 496
7 Joural of Busess Ecoomcs ad Maagemet, 206, 7(4): I multple attrbute decso-makg evromets, the cocept of deal pot has bee used to help detfy the best alteratve the decso set. Although the deal alteratve does ot exst real world, t does provde a useful theoretcal costruct agast whch to evaluate alteratves. Hece, we ca defe a deal attrbute value the deal alteratve A., where Let r = ( m, h, )( =, 2,, ) { } { } { }, { } { } { } max m m m = max m, h = m h, = m The we call: π = m h = m h (, 2,, ) =, =, 2,,. (3) A r r r, (4) the relatve pcture fuzzy deal alteratve. I the followg, we apply the cross-etropy to the MADM problems wth hestat fuzzy formato. Step. Defe the alteratves A ad A : ((,, ),( 2, 2, 2),(,, )) A = m h m h m h, =, 2,, m; (5) ((,, ), ( 2, 2, 2), (,, ) ) { } { } { } = A = m h m h m h ; (6) m = max m, h = m h, = m,, 2,,. (7) Step 2. Calculate t pcture fuzzy weghted cross-etropy betwee alteratves A ad A : m (, m C A A ) = w m l ( m = m m m m h h w h l ( h = ( h h ) ( h h ) w l ( = ( ) ( ) =, 2,, m. (8) ad select the best oe(s) accordace wth C( A, A ) ( =, 2,, m). The smaller the value of C( A, A ) s, the better the alteratve A s. I ths case, the alteratve A s close to the deal alteratve A. Through the weghted cross-etropy C( A, A ) ( =, 2,, m) betwee each alteratve ad the deal alteratve, the rakg order of all alteratves ca be determed ad the best oe ca be easly detfed as well. Step 3.

Coclusos ad the accordace wth The proposed method dffers from prevous approaches for fuzzy multple attrbute decso makg ot oly due to the fact that the proposed method use the pcture fuzzy set theory, but also due to the cosderato of the degree of eutral membershp besdes degree of postve membershp ad degree of egatve membershp the evaluato of the alteratve wth respect to attrbute, whch makes t have more feasble ad practcal tha other tradtoal decso makg methods real decso makg problems. Therefore, ts advatage s easly reflectg the ambguous ature of subectve udgmets because the pcture fuzzy sets are sutable for capturg mprecse, ucerta, ad cosstet formato the multple attrbute decso makg aalyss.
