IMI Colloquium

1960 年代に、数理計画法システムが商用化され、現在に至っている．私は 1974 年に富士通株式会社に入社し、数理計画法システムを中心としたOR分野の研究開発、顧客支援に携わってきた。1980年当時、LP計算は大型計算機センターで利用されるのが普通であったが、メインフレームが自社に導入されるようになり、LP計算がベンチマークの主役になったケースもある。その当時のLP計算では、ホストコンピュータのCPU使用率が 90 ％以上に達することもあった。 1000 式のLPモデルの実行に数時間かかることもあり、今とは隔世の感がある。当日の発表では、数理計画法システムの進化の歴史を振り返るとともに、次世代の数理計画法システム：LocalSolverの概要を紹介する。

Title : The history of mathematical programming system and the LocalSolver leading-edge trend to All-in-One solver

Abstract:
1960 A mathematical programming system is commercialized by the age and it has resulted in it at the present. I am 1974. FUJITSU, LTD. was joined for the year and it has been engaged in research and development of OR field centering on a mathematical programming system, and customer support. Although having been used in the mainframe computer was common those days of 1980 as for LP optimization, a mainframe comes to be introduced into its company and the case which became the leading role of the benchmark also has LP optimization. In the LP optimization of those days, the CPU usage rate of the host computer might reach more than 90 %. In the case of 1000 rows LP optimization problem, it took several hours, and there is a feeling of living in a quite different age with now. In an announcement on the day, while looking back upon the history of evolution of a mathematical programming system and I introduce the outline of the next-generation mathematical programming system : LocalSolver.
