Appropriate use of these techniques is considered in the present article. A brief presentation of the philosophy of quality assurance in production using the methods of SPC and SQC is followed by a terse explanation of the goals and techniques of SPCISQC. The applicability of the methods to process engineering is a special problem. Questions of the necessary adaptation and introduction into the conventional procedures of process control are discussed. Instrumentalization of plant with digital process controllers provides a framework for implementation of integrated solutions of such quality assurance systems in production. This is explained with the aid of examples.
strome in einem Unternehmen der ProzeBindustrie konnen die zugehorigen Geschaftsprozesse herausgearbeitet werden, deren Unterstutzung durch geeignete Systeme der Informationsverarbeitung eine effiziente Steuerung des Materialflusses und der Stoffumwandlung als Produktionsziel ermoglicht. Eine solche Betrachtung bringt nicht nur einen Hinweis auf die wichtigsten Funktionen der Informationsverar-beitung, sondern ebenso auf die notwendige Integration prozeRnaher Informationssysteme der Rezeptfahrweise, Produktionsplanung und Betriebsdatenverwaltung. Zu dieser Integration sind derzeit unterschiedliche Konzepte in der Diskussion.
Plant control systems for administration of formulations and processing of production data. Hitherto, support from electronic data processing in a company was generally on the managerial level and benefitted the commercial/administrative tasks occurring there. On the other hand, automation of production has been accelerated by the increasing use of digital systems such as stored program systems, process controllers, electronic data acquisition devices, and laboratory automation and information management systems. However, there was a gap between the two which is now beginning to close since the introduction of plant control systems. The tasks of these systems lie in process‐proximate balance, quality assurance, production overviews, formulation procedures, and optimum plant control. The benefit of such plant management systems lies in the accessibility of up‐to‐date information to all qualified persons involved in plant management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
