This paper reviews a cyclic scheduling model of repetitive manufacturing environments consisting of exible machines and multi-stage jobs. We explicitly model two system performance measures, throughput and ow time, while incorporating variability arising from uncertainty in operation processing times. We present an iterative approximation scheme to estimate the two moment behavior of our perfor...

Assessing Causality and Persistence in Associations between Family Dinners and Adolescent Well-being.

Adolescents who share meals with their parents score better on a range of well-being indicators. Using three waves of the National Longitudinal Survey of Adolescent Health (N = 17,977), we assessed the causal nature of these associations and the extent to which they persist into adulthood. We examined links between family dinners and adolescent mental health, substance use, and delinquency at w...

We show that long-run average cost function for the (R, T) policy with normally distributed demand has a structure similar to that of the corresponding (Q, r) model so that many of the useful properties of the latter model are applicable. In particular, (i) the optimal cost is relatively insensitive to the choice of the reorder interval, T, provided a near-optimal R corresponding to the chosen ...
