Humans Plus Agents Maintain Schedules Better than Either Alone

چکیده
Tracking and evaluating the progress of large, complex plans or schedules as they unfold in real time is extremely di cult for humans. In this paper we present a mixed-initiative system for the task of schedule maintenance in a simulated shipping network. A schedule maintenance agent monitors the network, predicting the occurrence of states that may result in reduced throughput and formulating schedule modi cations to avoid those states. The goal is to maximize throughput while minimizing disruptions to the original schedule. We present results of experiments in which human subjects attempt to obtain that goal both with and without the aid of the agent. We found that the human and the agent working together are able to achieve better results than either one working alone. In addition to looking at global performance measures such as throughput, we analyze individual schedule modi cation decisions made by subjects in an attempt to assign credit for the improvements in performance. This research is supported by ARPA-AFOSR contract F30602-91-C-0076.

Intraperitoneal Hydrocortisone plus Bupivacaine administration For Pain Relief after Laparoscopic Cholecystectomy, A Comparison with Bupivacaine Alone
Introduction: shorter hospital stay and less pain in comparison to open surgery considered to be major benefits for laparoscopic cholecystectomy. We compared the effect of intraperitoneal hydrocortisone plus bupivacaine with bupivacaine alone on pain relief following laparoscopic cholecystectomy. Methods: Sixty two patients participated in this double-blind, randomized clinical trial. Pati...
متن کاملMezlocillin and ticarcillin alone and combined with gentamicin in the treatment of experimental Enterobacter aerogenes endocarditis.
The efficacies of mezlocillin and ticarcillin, each alone and in combination with gentamicin, in the therapy of experimental left-sided Enterobacter aerogenes endocarditis in rabbits were compared. Each beta-lactam was administered intramuscularly at a dose of 180 mg/kg every 6 h either alone or with gentamicin (1.7 mg/kg intramuscularly every 8 h). Bacterial populations at the start of therapy...
متن کاملGeneration of Mature Monocyte-Derived Dendritic Cells in the Presence of Heparin and Monocyte Conditioned Medium: Phenotypic and Functional Comparison
Background: Dendritic cells (DC) induce tumor or pathogen-specific T cell responses in humans. Several laboratories have developed culture systems, including maturation factors for human DC from peripheral blood monocytes. We comprehensively compared standard maturation stimulus, an autologous monocyte-conditioned medium (MCM), with heparin for their ability to promote uniformly mature DC that ...
متن کاملCombining Human and Machine Intelligence for Making Predictions
Statistical models almost always yield predictions that are more accurate than those of human experts. However, humans are better at data acquisition and at recognizing atypical circumstances. We use prediction markets to combine predictions from groups of humans and artificialintelligence agents and show that they are more robust than those from groups of humans or agents alone.
