Due date-based metrics for activity importance in stochastic activity networks

A metric pair for assessing the importance of activities in stochastic activity networks based on completing a project on time (or reaching other project milestones) is presented. The metric pair is recommended as a supplement to other metrics of activity importance that have been suggested for use with Monte Carlo simulation. The differences in behaviour of the various metrics are analyzed to help understand the additional types of insights that would be available by including the new metrics in simulation-based analyses.
