DCS是分散控制系統(Distributed Control System)的簡稱，國內一般習慣稱為集散控制系統。它是一個由過程控制級和過程監控級組成的以通信網絡為紐帶的多級計算機系統，綜合了計算機(Computer)、通訊(Communication)、顯示(CRT)和控制(Control)等4C技術，其基本思想是分散控制、集中操作、分級管理、配置靈活、組態方便。DCS具有以下特點： (1)高可靠性 由于DCS將系統控制功能分散在各臺計算機上實現，系統結構采用容錯設計，因此某一臺計算機出現的故障不會導致系統其它功能的喪失。此外，由于系統中各臺計算機所承擔的任務比較單一，可以針對需要實現的功能采用具有特定結構和軟件的計算機，從而使系統中每臺計算機的可靠性也得到提高。
流程工業CIMS是一個復雜的綜合自動化系統，處理的對象是整個企業的全部生產活動，DCS作為一種有效的工具和實現手段，在流程工業CIMS中完成重要的基礎控制和實時生產數據采集、動態監控等功能。與管理類計算機相比，DCS能夠提供更加可靠的生產過程數據，使CIMS系統所作出的優化決策也更加可靠。
從功能上看，流程工業CIMS中的生產自動化系統、動態監控系統和在線質量控制都可以由DCS實現。從流程工業CIMS的層次結構看，DCS主要擔負過程控制和過程優化任務，有些生產調度和生產管理工作也可在DCS上完成。
