This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the Editor-in-Chief. The article duplicates significant parts of a paper that had already appeared in Journal of Grey Systems, Volume 8, Issue 1 (2005) pp. 1–12. DOI 10.30016/JGS.200507.0001. One of the conditions of submission of a paper for publication is that authors declare explicitly that the paper has not been previously published and is not under consideration for publication elsewhere.

The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.
