A recently proposed global congestion measure for CDMA networks is applied to call admission control, call dropping, and band allocation in multi-carrier CDMA networks. It is shown to perform comparably with existing techniques for call dropping, and better than existing techniques for admission control and band allocation. Difficulties arising in the measurement of this parameter are also inve...

the paper discusses the location-allocation model for logistic networks and distribution centers through considering uncertain parameters. in real-world cases, demands and transshipment costs change over the period of the time. this may lead to large cost deviation in total cost. scenario based robust optimization approaches are proposed where occurrence probability of each scenario is not know...

This paper studies congestion management based on congestion pricing as may be done by an Independent System Operator. Four main concepts are discussed: congestion pricing can lead to the same solution as an Optimal Power Flow, pricing need not have cost information available, good estimates of nonlinear cost coefficients are necessary, and pricing for congestion management is separable from pr...

 To use services transparently in a distributed environment, the Utility Grids develop a cyber-infrastructure. The parameters of the Quality of Service such as the allocation-cost and makespan have to be dealt with in order to schedule workflow application tasks in the Utility Grids. Optimization of both target parameters above is a challenge in a distributed environment and may conflict one an...

The major causes of network congestion are the lack of network resources and the irrational allocation of network resources. The traditional congestion control methods such as rate control, window mechanism, queue control and others can solve the congestion problem, but for the congestion due to irrational allocation fundamental solution is to make more effectively use of the network resources ...

In this paper we give a review of the applicablity of the convolution algorithm. By this we are able to evaluate communication networks (end-to-end) with e.g. BPP multi-rate trafhc models insensitive to the holding time distribution, rearrangement, minimum allocation, and maximum allocation. For each in dividual traflic stream we are able to find various congestion measures, overflow traffic, a...

the effects of planting date and single irrigation (si) allocation scenarios on increasing and stability of yield were investigated to determine the total water productivity and economical water productivity (wpe), for rainfed wheat at dryland agricultural research institute in maragheh, iran, during 2000-2004. the treatments included three sowing dates (early, normal and late), four allocation...
