1. A method of probability analysis-based regenerator site selection comprising: generating, by one or more processors, a plurality of data traffic conditions; generating, by the one or more processors, a plurality of demand sets; while applying each of the data traffic conditions in a simulated network including regenerator candidate sites: introducing, by the one or more processors, each of the demand sets to the simulated network, and recording, in one or more non-transitory computer readable mediums, a number of times each of the regenerator candidate sites is selected as a regenerator site; statistically analyzing, by the one or more processors, the number of times each of the regenerator candidate sites is selected as the regenerator site, wherein the statistically analyzing includes calculating, by the one or more processors, a standard deviation-weighted probability expectation (SDPE) value for one or more of the regenerator candidate sites; and based at least partially on the statistical analysis, selecting, by the one or more processors, a regenerator site from the regenerator candidate sites.
