Engineering is solving the pivoted problems of the state economy that are the productivity of industry and the quality of the output product. The solution to these problems is seeing by the intensification of the technological process and its structural arrangements. The intensification of the technological process has limitations due to its physics of execution. The structural arrangements of the process are limited by the technical indices. Both limitations depend on numerous physical, technical, and economic constraints. Finding the optimal solution for the pivoted problems of the industry depends on the tactical and strategic goals of the production economics. Both goals depend on the marketing environment. The tactical goal of the production process is solving by the optimization of its technological process and structural arrangements by the criterion of the maximal productivity rate of the physical process. The strategic goal is solving by the optimization of its production process by the criterion of the minimal production cost. Productivity theory considers physical productivity and gives the solution for the tactical goals of industrial engineering

Neutrosophic Number

In order to simplify the complex calculation and solve the difficult solution problems of neutrosophic number optimization models (NNOMs) in the practical production process, this paper presents two methods to solve NNOMs, where Matlab built-in function “fmincon()” and neutrosophic number operations (NNOs) are used in indeterminate environments. Next, the two methods are applied to linear and nonlinear programming problems with neutrosophic number information to obtain the optimal solution of the maximum/minimum objective function under the constrained conditions of practical productions by neutrosophic number optimization programming (NNOP) examples. Finally, under indeterminate environments, the fit optimal solutions of the examples can also be achieved by using some specified indeterminate scales to fulfill some specified actual requirements. The NNOP methods can obtain the feasible and flexible optimal solutions and indicate the advantage of simple calculations in practical applications.

In this paper we consider the technological process of manufacturing micromechanical gyroscopes, the output of which is divided into cells of the crystal plate and each cell contains a fixed number of product elements. The estimation of structural similarity for measurements of technical characteristics of various devices is offered. A relatively large value of structural similarity assessment means that there is a dependence of the quality of the manufactured devices on the position on the crystal plate. This gives a good reason for further work to improve the quality of the process or to change the technological scheme as a whole. The article considers a numerical example based on a real sample of microelectronic products. The proposed method can be used both in the process of adjustment of the production process and in the rejection of products, when further configuration of the equipment is no longer possible.

Through the process analysis of vehicle damper which involved methods of IE(Industrial Engineering), we can find work load imbalanced procedures. In that way, it changed process procedure, shorten the distance in logistics transportation, changed the chaotic production field. At the same time, we used process analysis and production analysis on the key operation, reallocated word and improved arrangement of work field [, laid off unnecessary works, shortened the working time and production cycle. As a result, the working intensity is reduced.

The Relationship

It is shown that increasing the role of control methods, identifying patterns and accuracy of performing technological operations, establishing the relationship between the characteristics of the technological process and the yield of suitable products, will ensure the reproducibility of technology and the formation of instrument structures with specified parameters. In the technological process of production, instrument structures are formed and constructive and technological foundations are implemented, on which the specified parameters are established in technological and final tests. Providing the specified parameters of device structures, depending on the production processes, is carried out on the basis of increasing the dielectric strength of oxide layers, improving the production process, and reducing the number of defects in oxide films. Improving the cleanliness during the production process allows you to reduce the level of defective structures. The inconsistency of the coefficients of thermal expansion of the materials used is the cause of failures of elements of integral electronics and a decrease in their reliability. Analysis of thermal effects and associated mechanical loads allows one to assess the optimality of the selected materials and to clarify the likely failure mechanisms. Knowledge of the failure mechanisms makes it possible to calculate the reliability of the device at the design stage, as well as to predict the reliability of the equipment being developed. The reproducibility of the technology is ensured by conducting a statistical analysis of the technological process, containing statistical processing, establishing statistical relationships between parameters, determining the regularities of the technological process, constructing regression models for the relationship between the yield of good products and modes of technological operations, and analyzing the stability of the technological process. The traceability of the relationship between the parameters of instrument structures and the technology of their manufacture allows to reduce the level of their defectiveness, statistical regulation, based on the measured values of the parameters, and determining their position relative to the regulation limits, ensures the accuracy of the production process.

In this paper we consider the technological process of manufacturing micromechanical gyroscopes, the output of which is divided into cells of the crystal plate and each cell contains a fixed number of product elements. It is shown that on the basis of the general ideology of the mathematical theory of optimal regression experiment planning, when using as the basis of the regression model on the basis of sample principal components, and as a criterion using the quantity of information on Shannon, it is possible to estimate the information content of the crystal plate cells. The ordering of cells in terms of information, in turn, provides the opportunity to accelerate the process of rejection of microelectronic products. A numerical example based on a real sample of microelectronic products is considered. The proposed method can be used both in the process of adjustment of the production process and in the rejection of products, when further configuration of the equipment is no longer possible.
