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
Xr = qrt+μrμ
Where qr is the resource usage per CPU hr. It is nonzero for failure identification personnel (qi) as well as computer time (qc). The quantity μr is the resource usage per failure. It is nonzero for failure identification personnel (μi), failure correction personnel (μf) and computer time (μc).
