Q. Resource usage with reference to software reliability models?

Resource usage: It is linearly proportional to implementation time t and mean failures experienced μ. Let Xr be the usage of resource r.

Then

X_r = q_rt+μ_rμ

Where qr is the resource usage per CPU hr. It is nonzero for failure identification personnel (q_i) as well as computer time (q_c). The quantity μ_r is the resource usage per failure. It is nonzero for failure identification personnel (μ_i), failure correction personnel (μ_f) and computer time (μ_c).
