Reliability Analysis and Redundancy Optimization of a Command Post Phased-Mission System

Abstract

This paper divides the execution process of the command post system into four stages: information acquisition, information processing, decision control and response execution. It combines multilayer complex networks with a phased-mission system. Most studies have only evaluated the reliability of phased-mission systems. This paper evaluates and optimizes the reliability of a phased-mission system. In order to improve the mission success rate and maximize the reliability of a command post system, this paper provides a multitasking node criticality index, and the index is used to identify the key nodes in the command post’s four-stage network Then, the hot backup system of the node is selected to determine the redundant structure of the key node. Under the constraints of the operation and maintenance costs of key nodes, with the goal of maximizing the reliability of the information processing network layer, the multitask redundancy optimization model of each stage is established. Finally, the reliability of the missions before and after redundancy optimization is compared, using the case analysis of the four-layer network to verify the effectiveness of the proposed model.

Redundancy-Based Resilience Optimization of Multi-Component Systems

“…Zhang et al [28] proposed the elastic efficiency importance measure and maintenance efficiency measure to determine the importance of components and guide the maintenance sequence. Dui et al [29] proposed node importance, determined the redundant structure of key nodes, and maximized the reliability of information-processing network layer tasks. Do et al [30] proposed a component preventive maintenance strategy based on time-dependent importance.…”

Reliability modeling and optimization of K/N phased mission system with backup missions and global redundancy strategy

“…Levitin 22 evaluated the PMSs considering the random shocks effect and the system structures are optimized. Dui 23 evaluated the system reliability of a command post‐phased mission system and a hot redundancy strategy is used for higher system reliability. Feng 24 proposed a BDD‐based method to evaluate the reliability of phased UAV swarms.…”
