International Journal of Web Applications Ying Cheng, Yong Xiao, Yanjun Fang 8 4 2016 http://www.dline.info/ijwa/fulltext/v8n4/ijwav8n4_2.pdf Optimization of computer communication network based on reliability theory is problem with multiple constrained conditions. Based on the analysis of reliability theory of computer communication theory, this research discussed the multiobjective optimal model in computer communication network combining with principle of multi-objective optimal design and completed a set of analysis on network communication system at the request of the given reliability goal of optimal design. Finally, it is found that, algorithm of computer communication network optimal design based on reliability theory is effective.
