Previous analytic approaches for all-optical networks have only allowed a random wavelength assignment policy in spite of the fact that network performance can be improved by other wavelength assignment policies such as first-fit wavelength assignment. In this paper, we develop an approximate analytic method to allow flexible wavelength assignment policies by virtue of a layered-graph approach....

In this work we establish analytic bounds for the energy efficiency of the 1+1 survivable IP over WDM networks using network coding. The analytic bounds are shown to be in close agreement with our previously reported results. They provide verification of the MILP and heuristics proposed previously and an efficient, compact means of evaluating the network results, and allow the performance of la...

In this paper we formulate an analytic framework for the restoration performance of path based restoration schemes in planar mesh networks. We analyze different switch architectures and signaling schemes and model their total restoration interval. We also evaluate the network global expectation value of the time to restore a demand as a function of network parameters. We analyze a wide range of...

This research study presents a comprehensive model for selection of decisive criteria to develop and integrate a fourth-party logistics concept in humanitarian logistics sector. The model is based on applying an analytic network process for determination of final criteria selection for a fourth-party logistics solution. The analytic network process is used to solve complex multiple qualitative ...
