1 Techno-economic balance of load-adaptive telecommunication network operation for energy efficiency improvements / Christoph Lange, Heiko Lehmann // .- 2013 .- Vol.2 .- P. 249 - 253 .- 624
Load-adaptive telecommunication network operation has crystallized as a promising option for improving the network energy efficiency. On the one hand significant energy savings are expected when the network capacity follows the traffic load, on the other hand efforts for preparing networks for this kind of dynamic operation are necessary regarding, for example, systems and network processes. To account for all this, an energy-related and a generalized techno-economic balance is developed. Results calculated for exemplary traffic load curves and boundary conditions show that there are significant monetary benefits to be expected in particular in case of moderate validity periods of the network configurations. Furthermore, the need to evaluate the load-adaptive network operation case from a techno-economic viewpoint carefully before employing it in a particular telecommunication network becomes evident.
2 Evaluation of telecommunication network operational reliability based on gray relation projection method / Chao Zhang ; Cunbao Ma ; Jiadong Xu // .- 2006 .- Vol.2 .- P. 6970 – 6974 .- 621
Telecommunication network reliability plays an important role in network management and decision-making, but most traditional methods for analyzing and estimating the telecommunication network reliability can't evaluate the network actually and roundly because it only considers a certain single performance or index of the network. According to the knowledge of reliability and systems engineering, a novel model for evaluating telecommunication network operational reliability is proposed based on multiple criteria decision making (MCDM).
