Résumé :

The purpose of this article is to determine the most difficult to install structural components of large-span buildings. Determination of the most complex structures for installation processes was carried out on the basis of comparative analysis on the indicators of labor intensity, volumes and complexity of installation works, hazard level of works at high altitudes, involvement of high-capacity cranes or powerful hydraulic lifts in erection processes, complex configuration and weight of mounted structures. Large-span coatings are the most difficult to erect from the entire list of bearing an

Résumé :

The automotive industry is developing at a fairly high pace. At the present stage of development of our society, the demands of consumers for these products are increasing more and more. In turn, this forces vehicle manufacturers to improve paint coatings, expand the color gamut, in order to increase the competitiveness of their products. The more modern the generation of the car, the more difficult the paintwork, therefore, the restoration operations. In this regard, the role of the importance of the quality of bodywork performance comes to the fore. Currently, car repair is a profitable busi

Résumé :

The problem of developing an algorithm for structural-parametric optimization of production and technological capacities of regional service centers for the repair of components and assemblies of aviation equipment is considered. A mixed-integer model has been formed, where integer variables determine the composition of maintainable components (MF) of aviation equipment and repair levels, and continuous variables are indicators of the cost and labor intensity of work with them. It is shown that the problem under consideration relates to difficult combinatorial optimization problems, that is, t

Résumé :

The structure of the labor intensity of aircraft manufacturing is considered, in which the largest part is occupied by the aggregate and final assembly. The need for redistribution of work between different types of production has been formed in order to further reduce the labor intensity of assembly by forming additional requirements for structural elements that differ from the design documentation and the fulfillment of which would be expected during assembly. The main ways to reduce the labor intensity of the unit and final assembly of modern aircraft have been identified, which consist of

Résumé :

The study of the state of health of the population requires special attention due to the difficult socio-economic situation in which the entire national economy and, above all, the agricultural sector found itself. The labor intensity of workers in this industry directly depends on the season of the year, mechanized labor-intensive processes, labor supply. Of particular concern are the unfavorable tendencies that are now manifesting themselves more vividly. The agrarian sector of Tatarstan employs about 400 thousand people, of which almost 300 thousand are directly in agriculture.

The influence of design routing on the possibility of assembling pipelines of ship systems is considered. As a result, it is planned to manufacture pipes for the backlog, ensuring successful installation to reduce the labor intensity of pipeline work and shorten the construction time of the vessel as a whole. To exclude deviations during the installation of ship pipelines systems, it is proposed to use direct pipes made with an admissible mixing and connection. According to the proposed approach, in which the joints are not installed perpendicular to the pipe axis, but mutually parallel, a lin

This chapter explores whether a new labor system could ever become law and overcome the massive political hurdles standing in the way. The path to victory is quite narrow. There needs to be sufficient grassroots activism to push labor issues to the top of the agenda, a strong majority of politicians willing to vote for pro-union policy, champions to drive the policy forward, and a favorable intellectual climate. As difficult as these are to achieve, they are possible if favorable trends continue and rise in intensity. The public must increasingly and more forcefully demand change, and the poli

Résumé :

Abstract Corrosion, either internal or external, along with other types of defects on pipelines eventually lead to leaks without proper treatment. This gives rise to several issues, including environmental and safety hazards, and in case of pipe leaks in a plant, a loss of the efficiency of the process or, ultimately, failure of the process. Replacing the corroded pipelines (piping) can be difficult, costly and time consuming especially for plant. A required shutdown causes major economic loss. Thus, instead of a replacement of the defected pipelines, the installation of online repair is a bet

The need to divide attention in order to deal with information flowing in from a number of sources is observable in many work settings. Although most people can perform several simple activities concurrently, such as eating and watching television (Sharon, 1997), making simultaneous decisions is difficult (Pashler & Johnston, 1998). For the majority, task overload causes errors in performance (Girard, 2007), a decline in the quality of treatment (Ruthruff et al., 2001), and longer reaction time (Levy et al., 2006).

Laboratory tests through field sampling can intuitively and effectively obtain various parameter data of material deformation and failure, thus providing theoretical and data basis for specific engineering design. But the laboratory test cost is high, the labor intensity is big, mainly cannot carry on the repetitive test to the single material, and the numerical simulation calculation just makes up for these shortcomings and can verify the laboratory test results.
