1993年5月24日至6月2日中国运筹学会可靠性学会于重庆—武汉召开了全国第一届系统可靠性及概率风险研究学术交流会。会议由清华大学核能技术设计研究院主办,重庆大学系统工程及应用数学系和武汉大学软件工程研究所协办。来自全国十四个省市及军队的有关院校、研究所以及工厂,企业的67各专家、学者和工程技术人员出席了会议,论文集收入论文57篇。会议听取了学会顾问何国伟教授关于从以性能为主转变为以效能为主的新的质量观的报告。他指出效能是可用性、可信性和固有能力(主要和性能有关)的综合,其数学公式为E=ADC。这种质量观的转变来之不易,海湾战争的巨大冲击波,终于使我国有关部门特别是军队 May 24, 1993 to June 2, 1993 China Society for Operations Research Reliability Society convened the first National Symposium on System Reliability and Probabilistic Risk Research in Chongqing-Wuhan. The conference was sponsored by Tsinghua University Institute of Nuclear Energy Technology Design, co-organized by Department of Systems Engineering and Applied Mathematics of Chongqing University and Software Engineering Institute of Wuhan University. 67 experts, scholars, engineers and technicians from relevant institutions, research institutes, factories and enterprises of 14 provinces, cities and military departments across the country attended the conference and 57 articles of the dissertations were collected. The meeting listened to the report of Prof. He Guowei, an advisor to the society, on the new outlook on quality that shifted from performance-based to performance-based. He pointed out that performance is the combination of usability, trustworthiness and inherent ability (mainly related to performance), the mathematical formula is E = ADC. The hard-won transformation of the concept of quality and the huge shock wave in the Gulf War have finally brought the relevant departments in our country, especially the army
