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.

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.

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.

The purpose of researches was an analysis of a motivational mechanism as an element of quality management in a technological process by means of the influence upon human element. To achieve a purpose set there were solved the following problems: - the analysis of basic factors defining techno-logical process quality was carried out (taking into ac-count human element influence upon a production process); - the influence of a motivational mechanism upon quality of a production process of vibromechanical treatment of parts. On the basis of work results there were offered additional professional competences of a processing engineer and an operator of metal-working machinery. The model of a compensating simulation of the mechanism for workers motivation is developed and a formula for its definition is offered.

The Impact

Given the low carbon transformation of our energy systems, demand response has the potential to increase the adaptability of electricity demand to a volatile electricity supply. In this article, we investigate the demand response potential for the case where substituting technologies are available in an energy-intensive industrial production process. The available production technologies may not only differ in their technical characteristics, but also vary by the necessary input materials. We present a generic linear optimization model for such a production process and apply it to a real-world example in the paper industry. The results show that the question of which substituting technologies are used in an optimal production schedule to which degree, is highly influenced by the combination of current input parameters such as prices. In direct consequence, the corresponding demand response potential is not a fixed number. From an operational perspective, this input dependency implies that the price relation of raw input materials used in substituting technologies can be a crucial driving force for the ability and willingness of industrial enterprises to provide demand response. In addition, from a strategic perspective, long-run investments in demand response potentials may rely on expected price development of major input factors.

Traditional economic manufacturing quantity (EMQ) model addressed the perfect production for product. However, there possibly exists the defective product in the production process. In this paper, we present a modified EMQ model with shortage based on considering the product revenue and the inventory cost. The economic production run length, the maximum shortage level, and the optimal warranty period are simultaneously determined for obtaining the maximum expected total profit per year. The numerical example and the sensitivity analysis are further provided for illustration.
