| Popis: | The paper and paperboard production is a complex totality of different operations which take place in individual units (apparatuses) of a technological system. The functioning of every machinery units which belongs to technological system depends not only on its parameter complex but also on all system state as a whole.When working out the research methodology of complex system functioning dynamics [1] the questions of creation and practical use of interaction structural model of complex technological system elements remained unsettled.During the work implementation the structural aspects of complex systems elements interactions are worked out. The end aim of such approach is problems modeling which are appearing in the water systems of paper and paperboard production with modern computers.It is known that complex technological system elements interact thanks to the connections are become settled and it ensures their coordinated functioning for raised aim achievement.For structural system model building as a whole and interaction aspects reflection of complex technological system elements the practice recommends to use the base theses of graph theory and topological analysis method of complex system analysis which are based on the use of mathematical icono-graphic ( topological) models.In such case every either incoming signal from environmental element or outgoing signal of technological system element has pointed way ( address) for this signal to reach technological system element or environment as an incoming signal. At the same time taking into account that environment leaves its “marks” on the functioning character of complex technological system it is also necessary to consider the interaction of paper and paperboard production system with environment.From practical point of view a material oriented directed steam graph and its presenting as the incedenzes matrix are the most obvious presentation form of relations between complex system elements.The central place of technological system which is submitted as a material oriented directed steam graph is occupied by graph top models what can allow to carry out with computer technics the computing experiment for definition of complex system state during any period of time.At the same time a part of graph tops belongs to environment elements and other parts make great number of technological system elements.The environmental elements are considered only because of their influence on technological system elements.The elements of technological system are multifunctional. That is why they must be researched concerning their influence on the quantity of waterdissoluble organic and mineral substances in water flows of paper and paperboard production proceeding from functioning aim of given technological system.A the same time on the imitational modeling stage of state of paper and paperboard production technological system a necessity appears to give the models of separate system elements as two components: statics and dynamics which in their turn can be divided in separate groups and classes.The dynamic component of all technological system can be opened only with use of computers by considering the mathematical models of its every element in intercommunication, i.e. with use of elements conjugation models of complex technological system. Розроблено структурні аспекти взаємодії елементів складних систем з використанням основних положень теорії графів та топологічного методу аналізу з метою моделювання проблем, що виникають у водопотоках виробництва паперу та картону. Використання імітаційного моделювання дає можливість відтворити динаміку процесів, які відбуваються у досліджуваній технологічній системі. |
