Through analyzing the changes of key services' performance index value before and after evaluation, this paper proposed a novel quantitative analysis method for network survivability based on grey relational analysis. Starting with the normalization of decision matrix with interval number, the proposed method firstly applied grey relational analysis to(More)
Survivability has emerged as a new phase for the development of network security technique, and how to improve the system survivability using effective technique is an important problem. This paper takes the requirement of emergency response as its research background, and a new algorithm is proposed based on resource reconfiguration. The algorithm focuses(More)
Survivability has emerged as a new phase for the development of network security technique, and how to improve the system survivability using effective strategy is an important problem. In this paper, by analyzing the fuzzy matrix game (FMG) theory and network survivability mechanism, a novel strategy selection model for network survivability based on FMG(More)
Anterior cervical discectomy and fusion (ACDF) and cervical disc arthroplasty (CDA) are the most commonly used procedures in cervical spondylosis. However, only a few published studies exist in the literature comparing these two operation types, particularly its mid-term efficacy and safety. Furthermore, in those studies, even large sample trials, when(More)
To overcome the challenges of recovery polices generation in the presence of inaccurate failure detection, a failure recovery model for microrebootable distributed systems based on discounted Partially Observable Markov Decision Processes is presented in this paper. Thus the reasonable recovery policies are generated by solving the POMDP model. To tackle(More)
