A systematic collection of control devices introduced to operate plants, factories, etc. smoothly and according to plan. Plants and factories are collections of many processes. Each process is diverse, such as a process to make intermediate or final products from raw materials or intermediate products, or a process to move or inspect products. As times have changed, plants and factories have become larger and more complex, but the development of the control systems that support them has been remarkable. Below we will briefly trace the process of that development. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
プラントや工場などの運転・操業を計画どおり円滑に行うことを目的として導入された制御装置の体系的集合。プラントや工場は多くのプロセスの集りである。各プロセスは原料や中間製品から中間製品や最終製品を作るプロセスであったり,製品の移動や検査のプロセスであったり,種々である。時代の進展とともにプラントや工場は大規模かつ複雑化してきたが,これを支えてきた制御システムの発展は目ざましいものがある。以下ではその発展の過程を簡単にたどる。
