タイトル（英文）

A SURVEY AND DISCUSSION ON DECISION SUPPORT SYSTEMS -IN RELATION TO SOME CONVENTIONAL RESEARCH TOPICS

概要 （図表や脚注は「報告書全文」に掲載しております）

本報告は，デシジョン・サポート・システム（ＤＳＳ）の中心的な技術として知識処理の重要性を論じたものである。ＤＳＳは，経営情報システムやデータベースなどと多くの関連性を持っているが，とりわけ知識操作にもとづく問題解決，自然言語による利用者との対話などに見られる知識能力にその特徴がある。本報告では，まず既存の計算機技術との対比においてＤＳＳの特徴的な概念を考察し，この視点からＤＳＳの先駆的な例とみられるいくつかの実験システムを調査した。ここにとりあげた実験システムは，ＭＩＴのＳＴＵＤＥＮＴ，スタンフォード大学のＤＥＮＤＲＡＬ，カーネギ・メロン大学のＧＰＳ，スタンフォード研究所のＳＴＲＩＰＳ，ＭＩＴのＳＨＲＤＬＵの５つである。

概要 （英文）

A DECISION SUPPORT SYSTEM IS A TOOL FOR PROFESSIONAL IN CERTAIN SPECIFIC FIELD OF ACTIVITIES, SUCH AS CORPORATE MANAGEMENT, MEDICARE, CONSULTING TO NAME A FEW. THIS SYSTEM SHARES THE FINAL GOAL, IN SOME SENSE, WITH THE IDEA OF THE MANAGEMENT INFOMATION SYSTEM, THE INFORMATION RETRIEVAL, AND THE DATABASE. THE MOST DISTINGUISHEDFEATURE OF THE SYSTEM, HOWEVER,WHICH DIFFERS IT FROM THE OTHER CONVENTIONAL TECHNOLOGIES IS THAT THE SYSTEM HAS AN INTELLIGENT POWER TO HOLD AND UTILIZE A HUGE VOLUME OF KNOWLEDGE SO AS TO SOLVE THE PROBLEMS THAT THE USERS OF THE SYSTEM HAVE. AS THE FIRST STEP OF OUR STUDY TOWARD REALIZATION OF A DECISION SUPPORT SYSTEM IN THE NEAR FUTURE, THIS REPORT STUDIES SOME OF THE FORERUNNING RESEARCHES AND SYSTEMS WHICH HAVE CONTRIBUTED NEW IDEA TO THE ADVANCEMENT OF TECHNOLOGIES IN THIS AREA, ESPECIALLY TO THE TREATMENTS OF KNOWLEDGE IN A COMPUTER. THIS STUDY COVERS SUCH EXPERIMENTAL SYSTEMS AS STUDENT AT MIT, DENDRAL AT STANFORD UNIVERSITY, GPS AT CARNEGIE-MELLON UNIVERSITY, STRIPS AT STANFORD RESEARCH INSTITUTE, AND SHRDLU AT MIT. THIS PAPER IS WRITTEN BASED ON THE STUDY WHICH WAS CONDUCTED BY THE AUTHOR WHO WAS A RESEARCH STAFF AT THE GRADUATE SCHOOL OF MANAGEMENT OF PURDUE UNIVERSITY, INDIANA, DURING FROM SEPTEMBER 1980 TO AUGUST 1981.
