In this work we consider the problem of downlink resource allocation for proportional fairness of long term received rates of data users and quality of service for real time sessions in an OFDMA-based wireless system. The base station allocates available power and bandwidth to individual users based on long term average received rates, QoS based rate constraints and channel conditions. We solve...

In this paper, we present an approach to safety scheduling in distributed computing based on strategies of resource co-allocation for complex sets of tasks (jobs). The necessity of guaranteed job execution until the time limits requires taking into account the distributed environment dynamics, namely, changes in the number of jobs for servicing, volumes of computations, possible failures of pro...

This article deals with solving distributed optimization problems equality constraints by a class of uncertain nonlinear heterogeneous dynamic multiagent systems. It is assumed that each agent an model has limited information about the main problem and access to state variables other agents. A algorithm guarantees cooperatively constrained agents proposed. Via applying this algorithm, do not ne...

An ant colony algorithm is proposed to improve the net present values of resource-constrained projects since the net present value is a critical criterion for a project with a long time span and considerable cash flows. The algorithm adaptively adjusts the allocation of scarce resources according to the pheromone generated by artificial ants in the previous iterations so as to maximize the proj...

in the market for factors of production usually the equilibrium will be stablished on the based of the equality between the value of marginal products of output and their relative price level. on the other hand the value of marginal product of output is a function of observed rate productivity of output and the market capacity of factors of production. thus the fluctuation in the rate of produc...

Formal models of business processes support the performance analysis of processes and the evaluation of redesign alternatives. This paper presents a formal model to analyze the behavior of resource-constrained processes. The model is developed using Colored Petri Nets (CPN or CP nets) and the supporting software package CPN Tools. In our approach, a business process consists of tasks and resour...

Ground stations (GS) are required during spacecraft (SC) operations to provide communications links between operation teams and the SC systems. Traditionally, the allocation of ground resources to SC is a highly constrained problem with sufficiently few solutions, where the process is conducted manually: stations are selected for communication support with certain SC for certain periods. There ...

In third generation (3G) cellular networks, WCDMA is a widely used technique for Quality of Service (QoS) improvement because of its high data transmission rate. Power control scheme is also very essential to reduce interference and improve network performance. Existing techniques are rarely considered for the power controlling scheme along with Resource Allocation for different traffic classes...
