Purpose – The paper aims to propose a systematic approach for human factors (HFs) automatic evaluation for entire maintenance processes in virtual environment. Design/methodology/approach – First, a maintenance process information model is constructed to map real maintenance processes into computer environment. Next, based on this information model, the automatic evaluation methods for visibility, operation comfort and reachability are presented. All evaluation results are weighted and added up to establish a comprehensive HFs evaluation model. Then, the methods mentioned above are realized as an HFs evaluation module, which is integrated into virtual maintenance simulation platform, software developed by our lab. Findings – An application in HFs evaluation of repairing hydraulic motor on container spreader is implemented, and an on-site survey is carried out. The comparison between the result from the survey and the result we get using the presented methods shows that our solution can support HFs fast assessment accurately and effectively. Practical implications – Through evaluating maintenance operation processes, engineers can better analyze and validate the maintainability design of complex equipment, and some potential ergonomic issues can be found and dealt earlier. Originality/value – The paper contributes to present a systematic approach to achieve HFs fast and accurate evaluation for entire maintenance processes, rather than for a few maintenance postures.

Цель исследований сформулировать совокупность требований к разработке системы утилизации диффузного стока с орошаемых земель, которую предлагается рассматривать как технологический процесс, реализуемый в пределах намеченного интервала времени и обеспечивающий с помощью комплекса технический и техно-природных объектов выполнение в необходимом наборе и комбинации следующих операций: транспортирование, аккумуляция, обработка и использование собственно диффузного стока, а также продуктов его обработки. Методологической основой исследований является системный подход в плане взаимосвязи разрабатываемых исходных требований с компонентами технологического процесса, которые выражаются при помощи категорийно-понятийного инварианта. В процессе исследований определены назначение и цели системы утилизации диффузного стока, представлены основные термины, описывающие данный процесс, а также их определения. В результате системного анализа процесса утилизации диффузного стока с орошаемых земель были установлены исходные требования к созданию системы утилизации диффузного стока, включающие девять компонентов технологического процесса, выраженных посредством следующих научных категорий: персонал, ресурсы, среда, управление, информация, модель, время, продукт.The aim of the research is to formulate a set of requirements for the development of a system for utilizing diffuse runoff from irrigated land, which is proposed to be considered as a technological process implemented within the intended time interval and ensuring, using a complex of technical and techno-natural objects, the necessary set and combination of the following operations: transportation, accumulation, processing and use of diffuse runoff itself, as well as its treatment products. The methodological basis of the research is a systematic approach in terms of the relationship of the developed initial requirements with the components of the technological process, which are expressed using the category-conceptual invariant. In the process of research, the purpose and goals of the diffuse drainage disposal system are determined, the basic terms describing this process are presented, as well as their definitions. As a result of a systematic analysis of the process of utilizing diffuse runoff from irrigated lands, the initial requirements were established for the creation of a system for utilizing diffuse runoff, which includes nine components of the technological process expressed through the following scientific categories: personnel, resources, environment, management, information, model, time, product.

The article discusses the concepts of information modeling and 3D modeling. The relationship between the concepts of a BIM and a 3D model is analyzed and the key differences are identified. The advantages of using a federated information model when creating complex BIM designs of processing plants are presented and compared with working in a single file. A brief overview of the existing software systems that may be used to create information and 3D models of processing plants is presented. The example of an information model design for the backfill material production shop based on the tailings of the Tominsky GOK concentrator is used to illustrate the interaction between various software packages related to the development of the corresponding sections of the 3D model (TX for the production technology, AP for the architectural solutions, QL for the reinforced concrete structures). The design algorithm used in these software packages is considered and the corresponding structural calculations are provided. The benefits and effectiveness of the corresponding software packages are described. The impact on the calculation quality and reliability, the time required for the design work, referencing between various parts of the design, the ability to search for collisions and subsequently minimize errors in the construction and equipment installation are also analyzed.

Students with persistent reading difficulties are often especially challenged by multisyllabic words; they tend to have neither a systematic approach for reading these words nor the confidence to persevere (Archer, Gleason, & Vachon, 2003; Carlisle & Katz, 2006; Moats, 1998). This challenge is magnified by the fact that the vast majority of English words are multisyllabic and constitute an increasingly large proportion of the words in elementary school texts beginning as early as grade 3 (Hiebert, Martin, & Menon, 2005; Kerns et al., 2016). Multisyllabic words are more difficult to read simply because they are long, posing challenges for working memory capacity. In addition, syllable boundaries, word stress, vowel pronunciation ambiguities, less predictable grapheme-phoneme correspondences, and morphological complexity all contribute to long words' difficulty. Research suggests that explicit instruction in both syllabification and morphological knowledge improve poor readers' multisyllabic word reading accuracy; several examples of instructional programs involving one or both of these elements are provided.
