Integral usul modellari

Modellar	Omillar ta’sirini aniqlash
f=xy	∆fx+∆fy=∆f
X omili ta’siri	∆fx = ∆xy0 +1/2∆x∆y, yoki ∆fx = 1/2∆x(y0 +y1)
Y omil ta’siri	∆fy = ∆yx0 +1/2∆x∆y, yoki ∆fy = 1/2∆y(x0 +x1)
f=xyz.	∆fx+∆fy+∆fz =∆f
X omili ta’siri	∆fx = 1/2∆x (y0z1+y1z0)+1/3∆x∆y∆z;
Y omili ta’siri	∆fy = 1/2∆y (x0z1+x1z0)+1/3∆x∆y∆z;
Z omili ta’siri	∆fz = 1/2∆z (x0y1+x1y0)+1/3∆x∆y∆z.
f=xyzq	∆fx+∆fy +∆fz +∆fq =∆f
X omili ta’siri	∆fx=1/6∆x*[3q0*y0*z0+y1*q0(z1+∆z)+q1*z0(y1+∆y)+z1*y0(q1+∆q)]+ ∆x*∆y*∆z*∆q / 4;
Y omili ta’siri	1/6∆y*[3q0*x0*z0+x1*q0(z1+∆z)+q1*z0(x1+∆x)+z1*x0(q1+∆q)]+∆x*∆y*∆z*∆q / 4;
Z omili ta’siri	fz=1/6∆z*[3q0*x0*y0+x0*q1(y1+∆y)+y1*q0(x1+∆x)+x1*y0(q1+∆q)]+ ∆x*∆y*∆z*∆q / 4;
q omili ta’siri	1/6∆q*[3z0*x0*y0+x0*z1(y1+∆y)+y1*z0(x1+∆x)+x1*y0(z1+∆z)]+ ∆x*∆y*∆z*∆q / 4.

Mahsulot hajmi o‘zgarishiga ishchilar soni va mehant unumdorligining ta’sirini tahlili

Omillar ta’sirini hisoblash quyidagicha bajariladi:
F = X * Y
Fx=(8*1235) + ½(8*(-28))=9880+(-112)= +9768.0
2. Fy=(-28*144)+1/2(-28*8)=-4032+ (-112)= - 4144.0
ΔF=ΔFx+ΔFy= 9768 + (-4144) = 5624.0
