Reliability Analysis for Task Fleet on NCW Liu Hong-qing1 Li Lu-ji2 Wang Wen-hong2 (1. Electronic Engineering College of Naval Engineering University, Wuhan 430033; 2. Naval Command College, Nanjing 211800) Abstract: In condition of NCW, task fleet can share operational resource between different platforms and organize fire channels across multi-platform. These usages are effective to extend the resource efficiency, and to enhance the reliability of the task fleet. In text, by establishing the mathematical model of the task fleet on NCW, the reliability was analyzed, and the essential principle to increase reliability was also expounded. Key words: NCW; task fleet; reliability
