摘要：Understanding the wide range of outcomes achieved by firms trying to implement Total Quality Management (TQM) and similar process improvement initiatives presents a challenge to management theory: A few firms reap sustained benefits from their programs, but most efforts fail and are abandoned. In this paper I study one dimension of this phenomenon: the role of impending layoffs in determining employee commitment to process improvement. Currently, the literature provides two opposing theories c...

The depot fills center replenishment orders on a first-come-first-serve basis. Defectives received at the centers are passed to the depot for repair and depot inventory replenishment.

摘要：To optimize large-scale queuing systems configurations, OR professionals typically use discrete event simulation packages to examine in detail the movement of entities through such systems, assuming stochastic but fixed arrival patterns. Demand aspects are, however, routinely ignored as few attempts are made to capture the feedback effect of queue performance on the arrival process. Econometricians, on the other hand, use a simultaneous equations estimation approach relying on past data, but t...
