dc.description.abstractenFor the analyst, experiment is the most important stage in many fundamental and applied research. In order to study the object as much as possible and learn about the complex of its properties, it is necessary to investigate it, namely: to carry out experimental researches and to record the results of these studies on the media. This is necessary to compare the achieved level of knowledge of the object with that of the researcher in the process of literary and patent searches. In the future, the knowledge gained during the experimental research is used for practical purposes. This is the main task of scientific search. In turn, the effectiveness of experimental research largely depends on the methodology used in the process of scientific research. The researcher's attention should be focused on at least three aspects of carrying out the search work, at the expense of which it is possible to save considerable time and material resources and, at the same time, to obtain the desired results. In the first stage, it should be noted that the study of the state of technological systems for the production of semifinished products, paper and cardboard shows that the individual blocks of such technological systems, and therefore the whole technological system is affected by the mass of independent deterministic values, called factors. These factors exert their influence in the process of mass preparation, including the stage of dissolution; cleaning; grinding; composing the composition; casting; pressing, drying of a cloth. After all, the production of paper or cardboard is a sequence of interrelated processes, which, in the long run, ultimately depend on the quality of the products being manufactured. In order to effectively reduce the number of factors that exert their influence, it is advisable for the experimenter to make a preliminary assessment of the influence of each of the factors identified in the literature and patent searches, and to form a group of the most significant factors on this basis. In the future, these factors will be involved in the next stages of experimental research. However, intuitive selection of significant factors is quite subjective and may lead to erroneous conclusions from the results of the analysis of the research results. Therefore, at the stage of preliminary research it is recommended to use statistical methods of selection of factors, namely: methods of expert assessments. These methods are based on the statistical processing of data obtained from a survey of specialists in the field of knowledge or analysis of scientific research. Expert assessments are based on the results of the most recent and unpublished scientific works performed by each expert. Despite their subjectivity, peer reviews provide useful, objective information. This information makes it possible to evaluate the impact of each factor under study. Using this method, the opinion of the expert group is considered to be more reliable than the opinion of the individual expert. The method is based on the fact that the unknown characteristic of the studied phenomenon is treated as a random variable, and each expert's individual assessment of the truth and significance of an event is a reflection of its law of distribution. In the second stage of research, an important aspect is to achieve maximum informativeness of the experiment. It is known that in the course of experimental research, the object under study responds differently to changing factors (one or more simultaneously) and, thus, exhibits its complex of properties. The task of the researcher is to plan the experimental studies so that the object in the course of its research maximally manifested its entire complex of properties, regardless of the internal structure of the investigated object, as well as the influence of these or other factors. Thus, the maximum reliability of the results of experimental studies in the conditions of random "noise" interference is ensured. Subsequently, multicriteria analysis of the basic plans and local transformations of each of them are carried out in order to select the most suitable for implementation at the request of the researcher. This is the second aspect of the methodology. The third, and very important, aspect of research methodology is the development of adequate mathematical models [4], on the basis of which a favorable field is created for modeling and finding optimal conditions with the use of computer technologies. At this stage, taking into account the complexity of technological systems for the production of semi-finished products, paper and cardboard, a number of adequate mathematical models, suitable for modeling purposes, have been created. Further stages of research work are the use of created mathematical models for modeling purposes. The task is to predict the levels of pollution of water flows of complex technological systems of paper and cardboard production with water-soluble organic, as well as mineral components under conditions of reduction of fresh water consumption from 40 m3 \ t to 10 m3 \ t. This will give you an opportunity to determine the initial semi-finished products, a complex of auxiliary chemicals, as well as with the scheme of return water use.uk
dc.description.abstractukРозроблено методологію, яка дозволяє передбачити значення параметрів оптимізації у станах (точках факторного простору), що не досліджувалися в процесі проведення експерименту. Моделювання відбувається на базі комплексу адекватних математичних моделей, які створені на основі попередньо проведених експериментальних досліджень. Моделюванню піддаються процеси екстракції водорозчинних органічних речовин із волокнистих напівфабрикатів в процесах виробництва паперу та картону з мінімальним споживанням свіжої води.uk
