4. 
   Mehnat sharoiti – o‘ta og‘ir;
   
5.

6. 
   “0” razryadli ishchining oylik tarif stavkasi 9400 so‘m;

10. 
    Tarif koeffitsientlar: K₆=3.471; K₅=3.181; K₄=2.904; K₃=2.641
    

Echim:

1. 
   Ishbay ishchilarning soatbay tarif stavkalarini aniqlaymiz:
   

Tst₆=(9400/171,1)*3.471*1,05*1,24=54.94*4.52=248.29 so‘m
Tst₅=(9400/171,1)*3.181*1,05*1,24=54.94*4.14=227.45 so‘m
Tst₄=(9400/171,1)*2.904*1,05*1,24=54.94*3.78=207.73 so‘m Tst₃=(9400/171,1)*2.641*1,05*1,24=54.94*3.44=188.92 so‘m

2. 
   Vaqtbay ishchilarning soatbay tarif stavkalarini aniqlaymiz:
   

Tst₅=54.94*3.181*1,24=216.70 so‘m
Tst₄=54.94*2,904*1,24=197.83 so‘m
Tst₃=54.94*2,641*1,24=179.92 so‘m

3. 
   Vaqtbay ishchilarning smenalik ish xakini aniqlaymiz:
   

I.x.=T_sm(T_ar.st5*1+ T_st4*2+ T_st3*1)=8*(216.7+197.83*2+179.92)=6338.24 so‘m.
4. Ishbay rassenkalarni aniqlaymiz:
R_i6=(T_st6*T_sm)/ N_i/ch(sm)=(248.29*8)/80=24.83 so‘m/t R_i5=(T_st5*T_sm)/ N_i/ch(sm)=(227.45*8)/80=22.74 so‘m/t
R_i4=(207.73*8)/80=20.77 so‘m/t
Ishbay ishchilarning reja bo‘yicha ish xaklarini aniqlaymiz:
I.x._ishbay=N_i/ch(sm)=*R_i*n_i=80(24.83*2+22.74+20.77)=7453.6 so‘m

6. 
   Ishbay ishchilarning xaqiqiy ish xakini aniqlaymiz: I.x._ishbay=93.17*84=7826.28 so‘m
   

6. 
   a) Reja bo‘yicha hamma ishchilarning ish xaki:
   

6338.24+7453.6=13791.84 so‘m
b) xaqiqiy ish xaki=6338.24+7826.28=14164.52so‘m.
8. 1 t mahsulot tannarxida ish xaki sarfi: I.x./N_i/ch(sm)

1. 
   reja bo‘yicha: 13791.84/80=172.40 so‘m/t
   
2. 
   xaqiqiy: 14164.52/84=168.63 so‘m/t
   

9. Mexnat unumdorligining o‘sishi natijasida 1 t mahsulot tannarxini
pasayishi (ish xakini kamayishi evaziga):
t/n=172.40-168.63=3.77 so‘m/t
Misol: Vaqtbay ish xaki turidagi qoliplovchi va uning 3-razryadli yordamchisini yillik ish xaki fondini aniqlang. T_nom=274 kun, ishga chiqmasliklar 33 kunga teng. Ish sharoiti o‘ta og‘ir. Mukofot va ustama xaklar 80% (to‘g‘ri ish xaki fondiga nisbatan). Qo‘shimcha ish xaki fondi 12% (asosiy ish xakiga nisbatan).
Smena davomi 8 soat.
Echim:
Unumli ish vaqtni aniqlaymiz: T_u=T_nom - ishga chiqmasliklar= 274-33=241 kun, yoki 241*8=1928 soat.
To‘g‘ri ish xaki fondini aniqlaymiz: T_u*T_ar.st*K

1. 
   qoliplovchi uchun : 1928*300=578400 so‘m
   
2. 
   yordamchisi uchun : 1928*224=431872 so‘m.
   

Asosiy ish xaki fondi=to‘g‘ri ish xakii fondi+mukofot va ustama xak=578400+431872+(578400+431872)*8=1818489.6 so‘m
qo‘shimcha ish xaki fondi – 12%=1818489.6*0,12=218218.75 so‘m
Umumiy ish xaki fondi=asosiy ish xai fondi+qo‘shimcha ish xaki fondi – 1818489.6 +218218.75=2036708.3 so‘m/yil yoki 2036,71ming so‘m.
