Consecutive-k-out-of-n (Con/k/n) system, a reconfigurable system, can improve the system performance by adjusting the redundancy and assignment of components. This paper aims to determine the optimal defensive strategy of Con/k/n systems under external risks. The defensive capability of Con/k/n systems is evaluated based on real-time system reliability, and a defensive importance measure (DIM) is constructed to optimize components’ redundancy locally. To solve the proposed optimization model effectively, a DIM-based genetic algorithm (DIGA) is developed by integrating the advantages of DIM’s local search with the global search ability of the classical genetic algorithm (CGA). The numerical experiment under 36 scenarios illustrates that DIGA is more effective than CGA verified by average defensive capability, robustness, and convergence generations. Moreover, the redundancy distribution analysis of Con/k/5 systems in the optimal defensive strategy shows that the redundancy of F(G) systems is in a spaced (continuous) way under spacing k-1 risk or continuous k risk.

Dilemmas of Managing State Defence : Political, Strategic and Legislative Perspective

The study is focused on state defence management, in particular its political, strategic and legal-comparative aspects. The issue of managing the defence of the State has been presented from a systemic perspective as a separate system, being a part of a higher system and at the same time containing subordinate elements. Appropriate government documents of a conceptual nature and provisions in the common law on defence management were chosen as the subject for political-strategic and legislative legal analysis. The result of the analysis is a presentation of the key gaps and flaws in the legal solutions that may affect the functioning of the State defence management system in wartime1, in particular those related to the decision-making process of system components. In addition, an attempt was made to assess the implementation of security concepts adopted in Poland over the years, mainly in the field of managing national security and defence.
