Based on the GSM radio architecture, general packet radio service (GPRS) provides users data connections with variable data rates and high bandwidth efficiency. In GPRS service, allocation of physical channels is flexible, i.e., multiple channels can be allocated to a user. In this paper, we propose four algorithms for the GPRS radio resource allocation: fixed resource allocation (FRA), dynamic...

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 ....

Resource management has been recognised as an important topic for the execution of business processes since long time ago. Yet, most exiting works on resource allocation have not paid enough attentions to process characteristics, such as structural and task dependencies. Furthermore, no effort has been made on optimising resource allocation by improving business processes. To address this issue...

The objective of the proposed project work is Downlink resource allocation for OFDMA-based next generation wireless networks subject to inter-cell interference (ICI). The main aim of the project is balanced performance improvement between cell edge and cell centre users. The resource allocation scheme consists of radio resource and power allocation, which are implemented separately. To achieve ...

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...

One of the key applications of operational research in health systems management is to improve the mechanism of resource allocation and program planning in order to increase the system efficiency. This study seeks to offer an innovative method for the planning and scheduling of health service units with the aim of reducing the patients' Length of Stay (LOS) in the Cardiac Surgery Ward of Razavi...

Today the most organizations (e.g. banks and insurance institutes) consist of the various units which under the control of the main organization (unified management) act independently. Sometimes the manager presents some services which incur costs such as advertisement and introducing a new technology. Most organizations consist of several individual units. Resource allocation issue appe...

Many biological, geophysical, and technological systems involve the transport of a resource over a network. In this paper, we present an efficient method for calculating the exact quantity of the resource in each part of an arbitrary network, where the resource is lost or delivered out of the network at a given rate, while being subject to advection and diffusion. The key conceptual step is to ...

Health is increasingly seen as relevant to foreign policy; nevertheless, it remains subordinate to other interests. In particular, the interests of security and economics are often presented as more critical than health. This is due to a failure to sufficiently recognize the legal obligations that states have undertaken to ensure the human right to health. This article argues that health should...
