Cost containment and workforce utilization typically leads to healthcare access regionalization. Little attention has thus been given to patient’s spatial accessibility in appointment scheduling. As a result, many outpatients encounter huge travel burden, especially when the service items are routine. We in this research consider a multi-clinic network. In the current practice, outpatient visit...

Distributed systems such as Grid- and Cloud Computing provision web services to their users in all of the world. One of the most important concerns which service providers encounter is to handle total cost of ownership (TCO). The large part of TCO is related to power consumption due to inefficient resource management. Task scheduling module as a key component can has drastic impact on both user...

this paper surveys parallel scheduling problems and metrics correlated to and then applys metrics to make decision in comparison to other policy schedulers. parallel processing is new trend in computer science especially in embedded and multicore systems whereas needs more power consumption to reach speed up. the qos requirement for users is to have good responsiveness and for service providers...

We consider the online problem of scheduling combination appointments for outpatients. Scheduling multiple appointments on a single day is high on the list of outpatient preferences. It is hard to achieve for two reasons: first, due to the typical distributed authority in hospitals, scheduling combination appointments requires coordination between departments. Second, there is a trade-off betwe...

task graph scheduling is a multi-objective optimization and np-hard problem. in this paper a new algorithm on homogeneous multiprocessors systems is proposed. basically, scheduling algorithms are targeted to balance the two parameters of time and energy consumption. these two parameters are up to a certain limit in contrast with each other and improvement of one causes reduction in the other on...

highly effective in developing and improving the quality of the provided services .so, the present study aims to compare the satisfaction of the patients suffering from anal fissure from inpatient and outpatient treatments. method: this cross-sectional study was conducted on 212 subjects who were selected through systematic sampling from the patients with anal fissure referring to motahari clin...

nowadays, scheduling problems have a considerable application in production and service systems. in this paper, we consider the scheduling of n jobs on a single machine assuming no machine idleness, non-preemptive jobs and equal process times. in many of previous researches, because of the delivery dalays and holding costs, earliness and tardiness penalties emerge in the form of linear combinat...

The management of outpatient consultations constitutes an important aspect of planning activities in surgical services (Vissers, 1979). The scheduling process used for clinic appointments determines the appointment date for any patient referred for consultation about an operation (Jun et al., 1999). Within a regional network of hospitals, a variety of methods may be used for scheduling surgical...

This paper presents a simplifiedlagrangian multiplier based algorithm to solve the fixed head hydrothermalscheduling problem. In fixed head hydrothermal scheduling problem, waterdischarge rate is modeled as quadratic function of hydropower generation andfuel cost is modeled as quadratic function of thermal power generation. Thepower output of each hydro unit varies with the rate of water discha...
