Nationalization of key production assets of core Russian industries as a fuzzy-logic scientific task

The strategic development problem of OJSC “Gazprom”, within which the division of the company to the stock and operating components is proposed, with the transition of the majority of the company's production assets in public ownership. Analysis of the nationalization process can be observed on the basis of fuzzy logic-balanced scorecard. The report contains a comparison between “volatility” and “risk” entities. It's shown that volatility cannot be used as a criterion in portfolio optimization cases, but should be replaced by criterion “risk” or “chance”. Risk is estimated using both probabilistic and fuzzy logical models.
