Analytic Evaluation of the Expectation and Variance of Different Performance Measures of a Schedule under Processing Time Variability
… only on the expected value and ignoring the variance of the measure used, the scheduling problem becomes purely deterministic and the significant ramifications of schedule variability are essentially neglected. In many a practical cases, a scheduler would prefer to have a stable schedule with …

Novel Approaches for Some Stochastic and Deterministic Scheduling Problems
… a method to evaluate both the expectation and variance of various performance measures for a given schedule. Our method is based on the use of mixture models to approximate a variety of distribution types. The Expectation-Maximization algorithm of Dempster et al. (1977) is applied to derive …
