When Does Forced Idle Time Improve Performance in Polling Models?
Sarkar and Zangwill (1991) showed by numerical examples that reduction in setup times can, surprisingly, actually increase work in process in some cyclic production systems (that is, reduction in switchover times can increase waiting times in some polling models). We present, for polling models with exhaustive and gated service disciplines, some explicit formulas that provide additional insight...
متن کاملMore on Using Forced Idle Time to Improve Performance in Polling Models
A recent interesting paper ~Cooper, Niu, and Srinivasan @2# ! shows how for some cyclic production systems reducing setup times can surprisingly increase work in process+ There the authors show how in these situations the introduction of forced idle time can be used to optimize system performance+ Here we show that introducing forced idle time at different points during the production cycle can...
متن کاملWhen Does Communication Improve Coordination?
We study costless pre-play communication of intentions among inexperienced players. Using the level-k model of strategic thinking to describe playersbeliefs, we fully characterize the e¤ects of pre-play communication in symmetric 2 2 games. One-way communication weakly increases coordination on Nash equilibrium outcomes, although average payo¤s sometimes decrease. Two-way communication further...
متن کاملWhen recanalization does not improve clinical outcomes.
See related article, pages 2761–2768. Treatment of ischemic stroke is intuitively simple with fast recanalization of blood vessels being the goal. However, this is frequently easier in theory than in practice. That is why there is some optimism in the stroke community regarding novel devices (eg, MERCI retriever system,1,2 Penumbra catheter,3 balloon angioplasty, and so on) for revascularizing ...
متن کاملDoes employee ownership improve performance?
Employee ownership is linked to better company performance on average. Employee ownership companies have more stability, higher survival rates, and fewer layoffs in recessions, potentially leading to lower unemployment in the overall economy. Employer stock tends to come on top of, rather than substitute for, regular employee compensation, and thereby adds to pay and wealth in general. The broa...
