Abstract
Based on the analysis of the functional capabilities of modern information systems, the paper substantiates the applicability of multidimensional combined information structures for computer-assistant planning in machinery production. A multidimensional optimization model has been developed for elementary technological surface-treatment routing in the case of using complex quality indicators determined by the operational properties of products. The dimensions of its coordinate space are determined by the number of technical constraints that govern the quality of the product. The paper provides an example of an algorithm that uses logical algebra operations to reduce the coordinate space of the model and to reduce the computational complexity of the design task.
Highlights
The concept of quality in relation to mechanical engineering products includes "... a set of properties that determine their suitability to fulfill their functional purpose in a given range of changes in operating conditions" [1, 2, 3, 4]
Mechanical engineering uses a system of simple indicators, which are subdivided into operational and production-and-technical ones [1, 2]
Insufficiency of accuracy tables is determined by the lack of data on changes in the values of quality and accuracy criteria in the course of the technological process when executing each pair of adjacent machining methods
Summary
The concept of quality in relation to mechanical engineering products includes "... a set of properties that determine their suitability to fulfill their functional purpose in a given range of changes in operating conditions" [1, 2, 3, 4]. E., either arranging a new production line or modernizing an existing one - in the general chain of technological design measures, there is a particular stage [3, 4] of forming possible options for routing, comparing their technical and economic indicators, and choosing the optimal option [6]. It is known [1, 6] that the formation of quality indicators is influenced by the finishing stages of machining, and by the entire sequence of technological operations. The issues of surface treatment sequence algorithmization with normalized quality requirements (hereinafter - a machining sequence, technological chain, elementary route) is not properly reflected by the methods of technological design
