We present a simple mean value analysis (MVA) framework for analyzing the effect of scheduling within queues in classical asymmetric polling systems with gated or exhaustive service. Scheduling in polling systems finds many applications in computer and communication systems. Our framework leads not only to unification but also to extension of the literature studying scheduling in polling system...

This position paper discusses the scheduling problem as collaboration between human and automated scheduling assistant. We compare two recent scheduling systems we have developed at SRI that both involve and enable the user in the scheduling process. While embedding fully automated scheduling algorithms, these assistant systems go beyond decision-aids. They work with and in service of their use...

this article describes the results of a short structured phone interview about follow-up after psychiatric discharge with 20 high volume facilities. several reported differences were found between facilities that had high versus low rates of follow-up after discharge. A managed care organization studies what helps patients keep outpatient appointments after inpatient discharge by Jeffrey schwar...

In the past years, many Grids have been implemented and became commodity systems in production environments. While several Grid scheduling systems have already been implemented, they still provide only “ad hoc” and domain-specific solutions to the problem of scheduling resources in a Grid. However, no common and generic Grid scheduling system has emerged yet. In this work we identify generic fe...

conclusions intravenous acetaminophen reduced pain following outpatient urological surgery more significantly than meperidine. patients and methods in a prospective, randomized, double-blind clinical trial, 100 outpatients of urological surgery were studied in two groups of acetaminophen (a) and meperidine (m). patients in group a received 1g of acetaminophen in 100 ml saline within 15 minutes ...

a quasi. experimental study was conducted to investigate the antagonistic effect of flumazenil on the   recovery of patients above the age 50 year from anaesthesia receiving benzodiazepine products in one of   iran medical sciences university hospital's operating rooms .   a total of sixty middle aged patients were selected sequentially . thirty of them (12 females and 18 males )   were in...

Background: Appointment scheduling system is a critical component in controlling patients’ waiting time, so can increase the efficiency and timely access to health services. It is also an important determinant of patient satisfaction. The aim of this study was to assess the relationship of using a scheduling system and outpatients’ waiting time in a general teaching hospital in Tehran, Iran. M...

the objective of this study was to determine incidence rate, type, and pattern of clinically relevant potential drug-drug interactions (pddis) in a large outpatient population of a developing country. a retrospective, descriptive cross-sectional study was conducted on outpatients’ prescriptions in khorasan razavi province, iran, over 12 months. a list of 25 clinically relevant ddis, which are l...

Classical scheduling abstractions such as deadlines and priorities do not readily capture the complex timing semantics found in many real-time cyber-physical systems. Time utility functions provide a necessarily richer description of timing semantics, but designing utility-aware scheduling policies using them is an open research problem. In particular, optimal utility accrual scheduling design ...
