in this paper, we present a genetic algorithm (ga) for optimization of a multi-mode resource constrained time cost trade off (mrctct) problem. the proposed ga, each activity has several operational modes and each mode identifies a possible executive time and cost of the activity. beyond earlier studies on time-cost trade-off problem, in mrctct problem, resource requirements of each execution mo...

Evidence-based programs for prevention and intervention in substance abuse are increasing. Community needs assessments and health rankings provide descriptions of local behavioral health needs but do not provide public health practitioners and policy makers with guidelines on the number of programs, health care practitioners, or interventions needed in the local substance abuse care system. Thi...

simultaneous routing and resource allocation has been considered in wireless networks for its performance improvement. in this paper we propose a cross-layer optimization framework for worst-case queue length minimization in some type of fdma based wireless networks, in which the the data routing and the power allocation problem are jointly optimized with fuzzy distributed h∞ control strategy ....

Human error is a significant and ever-growing problem in the healthcare sector. In this study, resource allocation problem is considered along with human errors to optimize utilization of resources in an emergency department. The algorithm is composed of simulation, artificial neural network (ANN), design of experiment (DOE) and fuzzy data envelopment analysis (FDEA). It is a multi-response opt...

DyTR is an approach to trust that goes beyond traditional authentication-based techniques, in which the trustworthiness of entities in a system adapts over time based on system events. Using a socio-cognitive model of trust, DyTR provides an adaptive trustassessment methodology that allocates resources dynamically to an initial level of credentials, continually assesses trust, and adaptively al...

A distributed real-time or embedded system consists of a large number of applications that interact with the physical environment and must satisfy end-to-end timing constraints. Applications in such system may offer different quality levels (such as higher or lower frame rates for a video conferencing application) across multiple factors or dimensions (such as frame rate, resolution). The end-u...

Resource allocation continues to be one of the primary challenges in federated computing systems. Currently, users are forced to either suffer the delays inherent to batch scheduling used by the supercomputing community or the tradgedy of the commons that befalls propotional share allocation as employed on PlanetLab. Market-based schemes have repeatedly been proposed as a possible solution but ...

The rapid rise in popularity of multimedia applications, such as VoIP, IPTV and Video Conferencing, intensifies the need to consider resource management for user satisfaction. Furthermore, improving Quality of Experience (QoE) in Software Defined Networks (SDNs) services is one of the important issues to be addressed by provisioning optimum resource management. In this paper, resource allocatio...

Emergency unit plays vital role in the hospital which is used to treat the patient who needs an immediate treatment. Critical patients need to be treated immediately, which requires sufficient resources. Resource planning is a most important scenario which needs to be considered while treating the patients in Emergency Department (ED) of hospitals by providing sufficient resources. Using simula...
