9254 Model for evaluatg the qualty for dstace educato based o the tellget computg BTIJ, 10(16 2014 INTRODUCTION Wth the rapd developmet of global servce dustry, especally uder the hstorc backgroud of greatly promotg moder servce dustry Cha, dstace educato s payg more ad more atteto to servce gradually. Dstace educato possesses the feature of "dustralzato", ad t s accompaed wth offerg ad usg vsble product, such as textbook; but ts fudametal product s stll educato servce ad ts core value derves from a seres of actvtes amog the servat (cludg teacher ad maager ad customer (studet of e-learg school ad study ceter. Therefore, dstace educato belogs to servce dustry, complyg wth basc rule of servce dustry, ad servce s the dustry essece of dstace educato [1-5]. From the perspectve of servce, the thess syllogstcally apples some relevat theory of servce dustry to dstace educato feld, whch have bee test the case study ad acto study, ad costructs a theoretcal system framework of dstace educato servce prelmary wth servce vew of "quas-publc product" of dstace educato as recogto foudato ad wth system vew, qualty vew, effcecy vew of dstace educato as the core. Vew o the product of dstace educato servce. The product of dstace educato servce s "quas-publc product", whch has the characterstcs of both publc product ad prvate product. I addto to teachg servce, the product of dstace educato servce abudatly cotas the servce of maagemet, the servce of facltes, the servce of campus culture, ad the servce for specal studets, whch are provded for the purpose of mprovg the qualty of teachg servces. Each of above metoed servces composes of four parts: explct servces, mplct servces, facltatg goods ad evromet, whch costruct the servce package of dstace educato orgac tegrty. Vew o the system of dstace educato servce [6-9]. The system of dstace educato servce cludes four elemets: "staff", "customers", "servce teracto"," equpmet ad evromet", whch carres out dstace educato servce ad creates the servce package of dstace educato together. Servce staff ad customers are the provder ad cosumer of dstace educato servce respectvely, equpmet ad evromet s ecessary codto of the servce, ad servce teracto s the core of the system, Sometmes, equpmet teracts wth customers drectly ad form servce teracto. Vew o the qualty of dstace educato servce [10-12]. The qualty of dstace educato servce dcates the degrees how dstace educato orgazatos satsfy the eeds of ther customers, such as studets, famles, eterprses, socetes, etc [13]. I ths paper, we vestgate the multple attrbute decso makg problems for evaluatg the qualty of Dstace educato based o the tellget computg wth tutostc fuzzy formato. We utlze the tutostc fuzzy Este weghted average (IFEW operator to aggregate the tutostc fuzzy formato correspodg to each alteratve ad rak the alteratves ad select the most desrable oe (s accordg to the score fucto. The remader of ths paper s set out as follows. I the ext secto, we troduce some basc cocepts related to tutostc fuzzy sets. I Secto 3 we troduce the MDM problem deal wth evaluatg qualty for Dstace educato based o the tellget computg wth tutostc fuzzy formato. I Secto 4, a llustratve example s poted out.

9256 Model for evaluatg the qualty for dstace educato based o the tellget computg BTIJ, 10(16 2014 I the followg, we apply the IFEW operator to evaluate the qualty for Dstace educato wth tutostc fuzzy formato. Step 1. Utlze the decso formato gve matrx R %, ad the IFEW operator ( μν ( r% =, =IFEW r%, r%, L, r%, = 1, 2, L, m. (5 ω 1 2 to derve the values r% ( = 1, 2, L, m of the alteratve S. Step 2.

NUMERICL EXMPLE Sce the mddle of 19th cetury, the mode of dstace educato has greatly chaged wth the developmet of commucato techology. t preset, based o the developmet ad applcato of formato techology, dstace educato experts dvde the developg process of dstace educato to three phases: correspodece educato from the mddle of 19th cetury to the mddle of 20th cetury, multmeda-aded dstace educato from the mddle of 20th cetury to the ed of 1980s ad Web-based dstace learg sce 1990s. The chage of teachg mode always brgs a seres of problems whch we ca ot avod. I the late of 1990s, two-way vdeo coferecg system based o satellte ad Iteret techology were employed by Rado ad Televso Uverstes at all levels across Cha. Sce 1998, more ad more uverstes have started to offer dstace educato courses. d by the ed of 2003, the umber of uverstes whch mplemet tral Web-based structo has amouted to 68, cludg the Cetral Rado ad Televso Uversty. However, the rapd expaso of scale ad the lack of expereces have resulted varous problems, the reducto of teachg qualty ad socal trust. The ma problems are as follows: o complete qualty guaratee system, o ufed qualty stadards, o forceful supervso of the teachg process, low effcecy of et learg, the lack of systematc teachg support ad servce, the lack of practcal techque trag for farmers ad the combato of school ad eterprse. Faced wth the curret stuato of moder dstace educato, educators should aalyze these problems carefully, fd out the causes ad come up wth reasoable suggestos so as to keep dstace educato growg steadly. The followg thess s a attempt to explore seres of exstg problems based o the research whch has bee doe both at home ad abroad wth regard to the mode of dstace educato ad the wrter wll, terms of the socal demad ad the practcal problems of web based structo, rase some measures to be take ad suggestos to further perfect dstace educato. Ths secto presets a umercal example to llustrate the method proposed ths paper. There s a pael wth fve possble Dstace educato = to select. The experts select four attrbute to evaluate the fve Dstace educato schools: 1G 1 schools ( 1, 2,3, 4, 5 s the evromet of teachg ad studyg; 2G 2 s the maagemet of teachg formato; 3G 3 s the currculum desg ad target; 4G 4 s the empathy ad the teachg practce. The fve possble Dstace educato schools ( = 1, 2,3, 4, 5 are to be evaluated usg the tutostc fuzzy formato by the decso maker uder the above four attrbutes whose 0.30,0.10,0.40,0.20 T, as lsted the followg matrx. weghtg vector ω = ( %= 1 2 3 4 5 G1 G2 G3 G4 ( 0.4,0.6 ( 0.3,0.5 ( 0.7,0.3 ( 0.3,0.4 ( 0.5, 0.4 ( 0.6, 0.2 ( 0.2, 0.2 ( 0.6, 0.2 ( 0.5, 0.3 ( 0.5, 0.2 ( 0.6, 0.4 ( 0.6, 0.1 ( 0.2, 0.3 ( 0.8, 0.2 ( 0.5, 0.2 ( 0.5, 0.4 ( 0.6, 0.46 ( 0.6, 0.1 ( 0.4, 0.4 ( 0.7, 0.2 The, we utlze the approach developed to evaluate qualty of Dstace educato order to select the best Dstace educato schools.
