Research knowledge about technology and economic aspects for decision making

摘要

Changes in the Field Technology of Management will have a positive effect in many ways inside and outside factories. Many researchers and companies have been interested in developing smart devices and communications buses. Distributors and manufacturers are involved with these projects and they develop new elements for process management. Some decision makers and end-users of industrial companies have been also involved with different kinds of projects. But what do they really think about the reliability and performance of current field technology and what are their demands for new solutions ? This research project has attended to define, what are their real opinions are about technology and it's related economic aspects. In addition the criteria of decisions have been found for choosing field elements, e.g. measurements, actuators, controllers, communication systems and their properties. Seeking information from both paper and electric documents, this Research work has inquired into the demands of communication technology, maintenance and service points, the education and experience of users, successful co-operation inside factories, the operations of upper level systems and their connections and process and system planning, too. The researcher has been pursuing his doctoral thesis in Finland in connection with a European Community Program carried out during 1994-95 at the Fraunhofer Institute in Karlsruhe, Germany. The results were collected from 20 factories and 50 experts from a group of 150 person's which were from the Finnish chemical, pulp and paper and steel industry. The main results of process management show that the demands of measurement reliability, the compatibility operation of whole technology, and process continuing activity are the most important and disturbances in process had to be minimized, too. The Reliability of connections using cables and mechanical interfaces, successful technology planning and the activities of users will influence the choice of Field Technology. The most important economical arguments, which could improve profit, are co-operation between people and the entire reliability of technology.
