Q. Drive an expression for peak manning of a project using Nordes - Rayleigh equation .
Ans Norden Rayleigh curve utilized to approximate software project .
M(t) =Man power utilization
= dy/dt = 2kate-at2 -------------(1)
K = Area under the curve t=time
Integrating eg . (1) with respect to t
Y(t) = k[1-e-at2] ----------------(2)
Differentiating eq (1) with respect to t
M'(t) = d2y/dt2 = 2kae-at2(1-2at2) ---------(3)
Put a=1/2td2 and t=td in eq (1)
M(t) = 2kate-at2 = 2k*1/2t2d *td e-1/2td2*td
= k/tde-1/2 = k/tde1/2
M0 = k/tde1/2
M0 = peak manning of a project .
