概要

論文の詳細を見る
Utilization of computers in Japan began on a full scale around 1961, and from that time on has quickly spread keeping pace with the high-pitched economic growth. In spite of the recent economy recession, the number of computers installed reached 41,929, valued $10,682 million at the end of June 1977. This figure is second to the United States in the worldwide computer utilization. The application of computers has contiguously spread over various fields, become highly complexed and so phisticated. Reliability of computer systems has been important today, since it is impossible to talk about a1l the socia1 activities as well as politics and economy in disregard of influence of computers. So far, in Japan, the reliability of computers had been discussed mainly in terms of physical damages caused by flood, fire, earthquake and others as well as system failures such as equipment failure and software malfunction, etc. Recently, however, our concern increases toward the operational aspects of the issue, such as invalid or malicious usages of systems/information, computer robbery, privacy violation and so forth. In this, I report the current status of computer reliability problems, their Japanese peculiarities and how we are going to prepare for them today. I also touch briefly upon the state of arts reliability features seen in Japanese computer systems.
