The Russian hybrid warfare strategy – neither Russian nor strategy

Following Russia’s annexation of Crimea and its initial actions in eastern Ukraine in 2014, the term hybrid warfare has received much public attention. Many have argued that the Russian actions we saw in Ukraine were part of a completely new strategy while others have suggested that there was nothing new in Russia’s actions. This article takes a critical look at these claims. Through the assessment of the history of the term hybrid warfare and a rigorous analysis of the so-called Gerasimov doctrine, this study finds that the Russian hybrid warfare strategy is rather a western myth than a formal comprehensive Russian strategic concept. Additionally, through the assessment of the Russian use of information operations and the way she has utilised the cyberspace in several recent conflicts, the study finds that against all claims Russia did not make these areas its main battlefield, but rather has been using them in support of its traditional concepts.

Two‐stage component test plans for testing the reliability of a series system

A system reliability is often evaluated by individual tests of components that constitute the system. These component test plans have advantages over complete system based tests in terms of time and cost. In this paper, we consider the series system with n components, where the lifetime of the i‐th component follows exponential distribution with parameter λ_i. Assuming test costs for the components are different, we develop an efficient algorithm to design a two‐stage component test plan that satisfies the usual probability requirements on the system reliability and in addition minimizes the maximum expected cost. For the case of prior information in the form of upper bounds on λ_i's, we use the genetic algorithm to solve the associated optimization problems which are otherwise difficult to solve using mathematical programming techniques. The two‐stage component test plans are cost effective compared to single‐stage plans developed by Rajgopal and Mazumdar. We demonstrate through several numerical examples that our approach has the potential to reduce the overall testing costs significantly. © 2002 John Wiley & Sons, Inc.
