The role of performace apprasal of huma resource maagemet the moder eterprse s becomg creasgly promet, ad has become the core ssue of huma resource maagemet. There are two basc methods, qualtatve ad quattatve apprasal, the employee performace apprasal. However, there are a large umber of ucertaty fuzzy cocepts the huma resource apprasal, whch make lots of dexes are dffcult to drect quatfy. So the artcle utlzes the tutostc fuzzy set TOPSIS method to evaluate the employee performace. Through the case study, the method ca evaluate the employee performace more comprehesve ad effectve. Therefore, the method ca provde strog support decso-makg, such as trag, promoto, rewards ad pushmets huma resource maagemet. d t s a effectve performace apprasal method.

To some extet, huma resources have bee the frst core compettveess of eterprses. Therefore, huma resource maagemet has a pretty mportat sgfcace to the eterprse []. Performace apprasal s a mportat part of huma resource maagemet, ad t has a vtal role mprovg the employee productvty ad motvato ad retag talet. The purpose of employee performace apprasal s show Fgure. For the performace evaluato, the most crtcal part s to select the approprate apprasal method. lthough some compaes have establshed a performace apprasal system, the overall effect of the performace apprasal s ot deal due to some dexes are sometmes dffcult to quatfy. Therefore, huma resource maagers eed to cotue to explore the performace evaluato methods, ad mprove the performace apprasal system [-4]. Performace apprasal s oe of the focuses of maagemet theory research recet decades, so scholars ad maagers make useful explorato to the performace apprasal from dfferet pot of vew. The key ssue s how to buld a sutable eterprse performace apprasal system, whch scholars ad maagers have a cosderable debate o, ad they also preset a varety of performace apprasal systems [5]. Key performace dcators (KPI) are a evaluato tool for huma resources ad busess performace maagemet. It emphaszes ISSN: 005-446 IJUNESST Copyrght c 05 SERSC
Vol.8, No.3 (05) the maagers must select -6 ob cotet tems as apprasal dexes whch are crtcal ad are more closely wth the orgazatoal obectves, so that the employees ca prortze the work. L Yqua appled the KPI to the performace apprasal of mddle maagers uverstes, ad establshed a performace apprasal system of mddle-level maagers uverstes [6]. Zhou Yucheg utlzed the KPI method to costruct the performace apprasal system of employee the fuctoal departmet from the customer perspectve [7]. 360 pprasal Method, also kow as the all-roud apprasal method, apprases the employee s work utlzg the dfferet ettes together, such as the employees themselves, the superor, colleagues, subordates, customers, etc. Yag Chuyg used the 360-degree apprasal method to the performace apprasal of core staff [8]. Zhao Fegchag appled the 360-degree performace apprasal method to the mddle maagers the eterprses [9]. The Balaced Score Card (BSC), based o the tradtoal facal dcators, establshes the four-dmesoal ratg dal from four basc dmesos whch are creatve learg, teral processes operatg, exteral customer servce ad ecoomc beeft, ad the sets the approprate performace evaluato dexes system based o the above framework. Therefore, maagers ca reflect the performace of the orgazato ad staff comprehesvely ad ca coduct the dyamc motor. Yag Yuqag appled the BSC to the performace evaluato of the sales team [0]. Su Qgl uses the BSC to evaluate the cvl servats performace []. The forced dstrbuto method s a method to revse ad adust the results of the performace evaluato. L Yume ad Sog Naru appled ths method to the staff performace apprasal study the state-owed eterprses []. Maagemet by Obectves (MBO), proposed by Peter Drucker, meas employees establsh ther persoal goals cosultato wth superors, whch are based o the compay's strategc goals ad obectves of the relevat departmet, ad these goals should be as cosstet as possble. Lag Zhedog used the MBO to evaluate the performace of maagers [3]. Feg Guohua evaluated the performace of the mddle maagers the state-owed busess, combg the KPI ad the 360-degree method [4]. Q Jg evaluated the performace of the mddle maagers the state-owed eterprses, combg the BSC ad 360-degree method [5]. I the applcato research of performace apprasal, the foreg scholar Clevelad beleved that performace apprasal ca provde related formato for persoel decso-makg, cludg salary, ob recommedato, trasfer, trag programs, staff developmet ad performace feedback [6]. Spageberg ad Herma proposed a performace evaluato model wth strategc tegrato, emphaszg the cetve ad costrat to the results of performace apprasal, to ecourage the employee wth hgh performace ad push the employees wth poor performace [7]. Boswell ad Boudreau cosdered that the value oretato ad developmet oretato were the two goal oretato of the performace apprasal. The value oretato focused o evaluatg the prevous performace of employees, regardg the results of the performace apprasal as the bass to employees reward or pushmet. Whereas the developmet oretato cosdered the results of apprasal as the bass to mprove the performace of staff the future [8]. Pettoh thought that the staff performace apprasal facltated other huma resource maagemet actvtes the actual ecoomc maagemet [9]. I summary, each performace apprasal method has ts advatages ad dsadvatages. However the huma resource apprasal s a mult-level, mult-factor comprehesve evaluato, there are a lot of fuzzy ucertaty employee performace apprasal, ot oly obectve factors, for example, may performace dexes are dffcult to quatfy, but also lots of subectve factors, such as huma resource maagers experece, kowledge ad values.

Vol.8, No.3 (05) C d(, ) 0.89 5 5 d( 5, ) d( 5, ) 0.8 0.89 0.66 By the results of the calculato, accordg to the relatve proxmty degree of each scheme to the tutostc fuzzy set postve deal soluto, we ca obta the rakg of the employee performace: C3 C5 C C C.The performace of employee 4 3 s the hghest these fve employees, coformg to the calculato results of dstace before. That s to say the employee 3 s earest to tutostc fuzzy set postve deal soluto ad farthest away from the tutostc fuzzy set egatve deal soluto. The eterprse ca gve prorty to employee 3 whe gvg promoto ad reward. Whle employee 4 s earest to the egatve deal soluto ad further away from the postve deal soluto, hs performace s the lowest the fve employees. The employee ad huma resource maagers should work together to mprove hs self-qualty ad the level of work, so as to mprove hs performace as a whole. Through the case aalyss above, the value of each dex of employee 3 s larger o average, ad whe determg the tutostc fuzzy evaluato matrx, the experts gve a hgher score to the persoal qualtes, work performace, work atttude, of whch the weghts are hgher, of employee 3. The experts scorg are cosstet wth the results of the calculato, showg that the model has the avalablty the employee performace apprasal ad ca provde the obectve fact for the decso-makg of the huma resource maagers. 5. Cocluso The effectve employee performace apprasal plays a pretty mportat role perfectg the teral maagemet, mprovg the market compettveess of the eterprse ad attractg ad retag the excellet employees. The artcle establshes a set of employee performace apprasal dex system accordg to the characterstcs of the eterprse employee performace apprasal, descrbg the performace apprasal of employees comprehesvely ad systematcally, the apples the dex system to the employee performace apprasal. The artcle proposes the tutostc fuzzy set TOPSIS method based o tutostc fuzzy set ad TOPSIS method, the establshes the tutostc fuzzy evaluato matrx of each evaluato dex, ad calculates the dstace of each employee to the tutostc fuzzy set postve ad egatve deal soluto usg the weght of each evaluato dex ad the dstace tutostc fuzzy set. Therefore we ca obta the comprehesve evaluato dex of employee performace apprasal ad the rakg of each employee performace. It ca provde the obectve fact for the decso-makg for huma resource maagers. The case study shows that the tutostc fuzzy set TOPSIS method s effectve ad feasble the employee performace apprasal. Through the above aalyss, the tutostc fuzzy TOPSIS method s beefcal to evaluate the performace of huma resources more comprehesvely ad reflect the qualty of employee as a whole. The tuto fuzzy set TOPSIS method ca avod the problem that the qualtatve dexes are dffcult to quatfy of the tradtoal performace apprasal methods, makg the evaluato results relatvely obectve ad far, ad has hgh accuracy ad operablty. It ca provde strog support for the decso-makg, such as trag, promoto, rewards ad pushmets, of huma resources maagemet ad t s a effectve method for performace apprasal. The prcple of the method s smple ad s easy to mplemet. The method ca provde a ew thought for the complex multple attrbute decso-makg problems actual ecoomc maagemet, ad s expected to be appled more smlar felds. Copyrght c 05 SERSC 34
