Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Problems of development of complex technological objects models, on the example of coke chambers of delayed coking unit, which are characterised by fuzzyness of some output parameters, are investigated and an approach to their solution is proposed. A method for developing models of objects with fuzzy parameters has been developed and described, which is implemented in the development of clear and fuzzy models of coke chambers. The originality of the proposed method lies in the development of effective models of objects with fuzzy parameters using available statistical and fuzzy information and the idea of a systems approach. On the basis of the developed models, the simulation of the modes of operation of coke chambers was carried out and the optimal modes of their operation were determined. The obtained results of the proposed method are compared with the results of known methods and real production data, and the advantages of the proposed approach to modelling taking into account the fuzzyness of some output parameters of the object are shown.
