Abstract :
The concept of dynamic strength is closely related to reliability: the probability that a software system does not encounter a latent fault during execution. Dynamic strength is assessed by analyzing the interference between the execution profile, a probability density for system size, and the composite static strength distributions. Composite static strength is the sum of the relative software complexity metrics of each of the system´s software modules. Composite static strength is a density function with size as the variate. Latent faults occur in the region of interference when the execution distribution exceeds a critical level of the strength distribution. An important relationship between the execution profile and strength distributions is characterized by the return period function
