Das 1 Departmet of Mathematics, Brahmaptra Valley cademy, North Lakhimpr, ssam, Idia 2 Departmet of Mathematics, NERIST, Nirjli, Itaagar, rachal Pradesh, Idia BSTRCT The cocept of soft set is oe of the recet topics developed for dealig with the certaities preset i most of or real life sitatios. The parametrizatio tool of soft set theory ehace the flexibility of its applicatios. I this paper, we defie ititioistic fzzy soft matrices ad their operatios which are more fctioal to make theoretical stdies i the ititioistic fzzy soft set theory. We also defie five types of prodcts ad some reslts are established. Keywords: Soft sets,ititioistic fzzy soft sets, Soft matrices, Ititioistic fzzy soft matrices ad Prodcts of ititioistic fzzy soft matrices. INTRODUCTION Most of or real life problems i medical scieces, egieerig, maagemet, eviromet ad social scieces ofte ivolve data which are ot always all crisp, precise ad determiistic i character becase of varios certaities typical for these problems. Sch certaities are sally beig hadled with the help of the topics le probability, fzzy sets, ititioistic fzzy sets, iterval mathematics ad rogh sets etc. However, Molodtsov[8] has show that each of the above topics sffers from some iheret difficlties de to iadeqacy of their parametrizatio tools ad itrodced a cocept called Soft Set Theory havig parametrizatio tools for sccessflly dealig with varios types of certaities. The absece of ay restrictios o the approximate descrtio i soft set theory makes this theory very coveiet ad easily applicable i practice. Research o soft sets has bee very wide spread ad may importat reslts have bee achieved i the theoretical aspect. Maji et al. itrodced several algebraic operatios i soft set theory ad pblished a detailed theoretical stdy o soft sets[7].the same athors also exteded crisp soft sets to fzzy soft sets [4] ad ititioistic fzzy soft sets[6]. t the same time, there has bee some progress cocerig practical applicatios of soft set theory, especially the se of soft sets i decisio makig. Recetly, Çagma et al.[1] itrodced soft matrix ad applied it i decisio makig problems. I oe of or earlier work [2], we proposed the idea of Fzzy Soft Matrix Theory i seqel to [1] defiig some operatios.the preset paper aims to defie ititioistic fzzy soft matrix ad establish some reslts o them.this style of represetatio is sefl for storig a ittioistic fzzy soft set i compter memory ad which are very sefl ad applicable. 2.Prelimiaries Defiitio 2.1[8] Let U be a iitial iverse, P (U be the power set of U, E be the set of all parameters ad E. soft set o the iverse U is defied by the set of ordered pairs (f, E = {(e, f (e e E, ad f (e P (U }, where f : E P (U sch that f (e = φ if e. Here, f is called a approximate fctio of the soft set (f, E. The set f (e is called e-approximate vale set or e-approximate set which cosists of related objects of the parameter e E. 412
2 B. Chetia et al dv. ppl. Sci. Res., 2012, 3(1: Example 2.1 Let U={c 1,c 2,c 3 } be the set of three cars ad E ={costly(e 1, metallic color (e 2, cheap (e 3 } be the set of parameters,where ={e 1,e 2 } E. The f (e 1 ={c 1,c 2,c 3 }, f (e 2 ={c 1,c 3 }, the we write a crisp soft set (f,e={( e 1, {c 1,c 2,c 3 },(e 2,{ c 1,c 3 }}over U which describes the attractiveess of the cars which Mr. S(say is goig to by. Defiitio 2.2[3,5] Let U be a iversal set, E a set of parameters ad E. Let F (U deotes the set of all fzzy sbsets of U. fzzy soft set (f, E o the iverse U is defied as the set of ordered pairs (f, E = {(e, f (e : e E, f (e F (U },where f : E F (U. Here, f is called a approximate fctio of the fzzy soft set (f, E. The set f (e is called e- approximate vale set or e-approximate set which cosists of related objects of the parameter e E. Example 2.2 Let U={c 1,c 2,c 3 } be the set of three cars ad E ={costly(e 1, metallic color(e 2,getp (e 3 } be the set of parameters,where ={e 1,e 2 E. The (G,={G(e 1 ={c 1 /.6,c 2 /.4,c 3 /.3}, G(e 2 ={c 1 /.5,c 2 /.7,c 3 /.8}} is the fzzy soft set over U ad describes the attractiveess of the cars which Mr. S(say is goig to by. Defiitio 2.3[1 ] Let (f, E be a soft set over U. The a sbset of U E is iqely defied by R = {(, e : e, f (e} which is called a relatio form of (f, E. The characteristic fctio of R is writte by χ : U E {0,1}, χ (, e = { 1, (, e R R R 0, (, e R If U = { 1, 2,..., m }, E = {e 1, e 2,..., e } ad E, the the R ca be preseted by a table as give below: R e 1 e 2 e χ (, e χ (, e... χ (, e If a = χ (, e, we ca defie a matrix [ a ] 1 R 1 1 R 1 2 R 1 χ (, e χ (, e... χ (, e 2 R 2 1 R 2 2 R 2 M M M M χ (, e χ (, e... χ (, e m R m 1 R m 2 R m R i j a a a a a a M M M M a a... a = m1 m2 m which is called a soft matrix of the soft set (f,e over U. ccordig to this defiitio, a soft set (f, E is iqely characterized by the matrix [a ]. It meas that a soft set (f, E is formally eqal to its soft matrix [a ]. 3.Fzzy soft matrices: Defiitio 3.1[ 2 ] Let (f, E be a fzzy soft set over U. The a sbset of U E is iqely defied by R = {(, e : e, f (e} which is called a relatio form of (f, E. The characteristic fctio of R is writte by µ : U E [0,1], where µ (, e [0,1] is the membersh vale of U for each e E. R R 413
