“…В наших работах [14; 15] предложена система показателей, обеспечивающая оценку проектных решений в автоматизированном режиме [14], и обоснован обобщенный критерий эффективности (ОКЭ) ТПП [15], который представляет собой суммарное время работы оборудования для обработки заданной номенклатуры деталей и позволяет оценить влияние решений, принятых в различных проектных процедурах. Отсев нерациональных вариантов проводится по критериям, которые не обладают свойством гибкости, что может привести к исключению из рассмотрения вариантов, которые потенциально могли бы увеличить совокупные показатели эффективности работы производственной системы.…”

“…Для решения этого вопроса в работе [15] описана методика ранжирования проектных процедур по уровню влияния на значение ОКЭ. В результате проектные процедуры, имеющие более высокий ранг, обладают большей значимостью и влекут необходимость проведения менее жесткого отсева для увеличения количества анализируемых вариантов.…”

The development of the mechanical treatment workflow CAP system is aimed at the solution of a crucial task of reduction of terms and the improvement of quality of multiproduct machining manufactures work preparation, as the existing workflow CAP systems have not got the possibility of fast response to changes in a production situation often arising within the multiproduct manufacture. The authors of this paper developed the workflow CAP system, which contains the requirements of the design activity full automation, design solution multivariance, and the feedback with the engineering process implementation subsystem. The paper deals with the development of a mathematical model and the technique of searching for sustainable levels of selecting design alternatives depending on the production situation for the whole design procedures of the workflow CAP system. The authors prove the application of a mathematical tool of genetic algorithms; describe the mathematical model using its terms. As a gene, the level of selection in a separate project procedure is specified. A chromosome is a set of genes according to the project procedures. The objective function determines the minimum total time of processing of the specified nomenclature of parts based on the ranges of gene aggregates resulting from crossing and mutation operations. The result of the work is the mathematical model and the technique for identifying the sustainable levels of selection in each project procedure ensuring the possibility of self-adjustment of the workflow CAP system depending on the production situation.

The article deals with the algorithmic implementation of the complex of design procedures of the system of accounting requirements for assembly in design of manufacturing methods of mechanical processing. The implementation of this integrated approach within the framework of the existing multinomenclature production made it possible to obtain rational manufacturing methods of mechanical processing of parts that provide a 26 % reduction in the subsequent assembly of high-precision products due to a decrease in the number of assembly iterations. The number of incomplete parts (work-in-process) decreased by 5.5 % on average.

In current conditions, the necessity to produce many high-precision tooling and machines has increased many times over. That is why the improvement of such products manufacture becomes of paramount importance due to the increasing requirements imposed on them. The existing approaches to ensuring the quality and accuracy of high-precision products are not universal and not always can be implemented when producing high-precision goods. For a comprehensive solution to this problem, the authors proposed using an integrated approach – the complex of formalized design procedures of the system for accounting of the requirements to the high-precision products assembly when designing the manufacturing methods of machining. However, for the establishment of relations between the process design and designing preproduction of multi-product manufacture, the transition to the assessment of the production manufacturability of goods and deeper integration of this system into the structure of the system of automated sequencing of manufacturing methods, it is necessary to search for ways to improve the existing approaches of the developed system. The paper considered in detail the enlarged block of design procedures for the analysis of requirements to the assembly of high-precision products, since this stage is directly related to the designing preproduction, and the initial data obtained in the course of its implementation ensure the quality of choice of rational manufacturing methods of machining of parts. The authors propose the techniques to improve mathematical, methodological, and algorithmic support of this enlarged block implementation. The introduction of the proposed solutions will allow performing effectively the design dimensional analysis of a high-precision assembly unit in an automated mode and forming a set of assembly requirements, which, as a result, will allow ensuring the expansion of digitalization of the process design and designing preproduction and the transition to intelligent production systems.
