Abstract Sensitivity is an important concept in network evaluation, review, and improvement (design). A sensitivity analysis details the changes in the performance measure as a function of changes in parameters (components) of a network. Equations are obtained to calculate the change in the performance measure due to changes in its several parameters. These equations are used in improving the system performance and in calculating the range of variations of the performance measure. System improvement in GERT networks is achieved by increasing the equivalent probability and by decreasing the equivalent time and cost. The range is used in finding the effect of parameter variations on the confidence limits of the equivalent time and cost.
