Application of quantitative and qualitative methods for determination of priority development directions of companies implementing lean manufacturing

This article covers the issues of integration of qualitative and quantitative methods applied when justifying management decision-making in companies implementing lean manufacturing. The authors defined goals and subgoals and justified the evaluation criteria which lead to the increased company value if achieved. The authors identify the most important top-level rating indicators: receiving a profit and increase in cash flow. The lower level includes criteria: 1) created value, sales volume, productivity, customer satisfaction; 2) net cash flow, turnover of current assets, EBITDA; 3) amount of accounts receivable; acceleration of the time from receipt of the order to receipt of money, expansion of own dealer network; 4) loss reduction, reduction of indirect costs, reducing inventory. The application of the analytic hierarchy process and the involvement of experts of various services allow accelerating management decision-making with regard to the determination of the priority development directions in the current economic conditions and making the process objective to the maximum.Keywords: analytic hierarchy process, lean manufacturing, management accounting, decision-makin

Features of conducting the decoupling-analysis

At the present stage of development the issues of economic growth for any country becomes important. However, intensive economic growth leads to an exacerbation of a number of problems such as unbalanced exploitation of natural resources, decrease of quality of environment, increase of the costs of natural balance reproduction and so on. Therefore, in view of these problems, it is extremely important to disclose the essence of decoupling effect as an economic phenomenon that reflects the ability of an economy to grow without increasing pressure on the environment.

Aluminum nanoscales as hormetic response effectors in Fagopyrum esculentum seedlings

Aluminum (Al) nanoscales have been applied in many areas of production industries to produce cosmetic fillers, packaging materials, cutting tools, glass products, metal products, semiconductor materials, plastics, etc. Several studies have demonstrated the contradictory data for positive and negative effects of Al nanoscales on plants. The total length of seedlings grown for 21 days and the relative water content are used to determine the stimulating effects. In addition, the enhancement effect of Al nanoscales on photosynthetic pigments and the total phenolic and anthocyanin contents are determined. The growth stimulation and increase of the content of photosynthetic pigments are observed at the addition of 50 and 250 mg/L of Al nanoscales. Plant growth stimuli and the fixed beneficial action of Al nanoscales on morphofunctional traits at physiological and biochemical levels are interpreted as the hormesis phenomenon.Наночастинки алюмінію (Al) використовуються у багатьох сферах промислового виробництва для отримання косметичних наповнювачів, пакувальних матеріалів, різальних матеріалів, виробів зі скла, металевих виробів, матеріалів з напівпровідниковими властивостями, пластмас тощо.

Gender differences of basketball players aged 12-13 years according to the response to a moving object

Purpose: The study aims at the determining gender differences of basketball players aged 12-13 years in response to an object in motion that determines the predominance of excitation and inhibition processes. Material: The participants of the study are 58 basketball players aged 12-13 years, 35 are male basketball players and 23 are female. Male basketball players had 4-5-year training experience, female had 1,5-2-year experience. All athletes had normal visual acuity and were healthy at the time of the study. Young basketball players were informed about the purpose of the study. The computer program containing visual stimuli, moving with acceleration from different points of the monitor was used for testing. Results: The deviations from the target data as well the pole were taken into consideration. It demonstrated the predominance of excitation and inhibition processes of basketball players of different sexes. The response accuracy to visual stimuli without taking into account the pole during perception with the left eye and the right eye is shown. Conclusions: It was found out that the females’ response accuracy during monocular perception is more closely related to the response accuracy during binocular imaging, whereas the role of the males’ leading eye is increased during perception of objects from a convenient side. This may indicate the peculiar reactions under the conditions of double perception of objects in solving complex spatial problems

Random line tessellations of the plane: statistical properties of many-sided cells

We consider a family of random line tessellations of the Euclidean plane introduced in a much more formal context by Hug and Schneider [Geom. Funct. Anal. 17, 156 (2007)] and described by a parameter \alpha\geq 1. For \alpha=1 the zero-cell (that is, the cell containing the origin) coincides with the Crofton cell of a Poisson line tessellation, and for \alpha=2 it coincides with the typical Poisson-Voronoi cell. Let p_n(\alpha) be the probability for the zero-cell to have n sides. By the methods of statistical mechanics we construct the asymptotic expansion of \log p_n(\alpha) up to terms that vanish as n\to\infty. In the large-n limit the cell is shown to become circular. The circle is centered at the origin when \alpha>1, but gets delocalized for the Crofton cell, \alpha=1, which is a singular point of the parameter range. The large-n expansion of \log p_n(1) is therefore different from that of the general case and we show how to carry it out. As a corollary we obtain the analogous expansion for the {\it typical} n-sided cell of a Poisson line tessellation.Comment: 26 pages, 3 figure

ϒ production in p–Pb collisions at √sNN=8.16 TeV

ϒ production in p–Pb interactions is studied at the centre-of-mass energy per nucleon–nucleon collision √sNN = 8.16 TeV with the ALICE detector at the CERN LHC. The measurement is performed reconstructing bottomonium resonances via their dimuon decay channel, in the centre-of-mass rapidity intervals 2.03 < ycms < 3.53 and −4.46 < ycms < −2.96, down to zero transverse momentum. In this work, results on the ϒ(1S) production cross section as a function of rapidity and transverse momentum are presented. The corresponding nuclear modification factor shows a suppression of the ϒ(1S) yields with respect to pp collisions, both at forward and backward rapidity. This suppression is stronger in the low transverse momentum region and shows no significant dependence on the centrality of the interactions. Furthermore, the ϒ(2S) nuclear modification factor is evaluated, suggesting a suppression similar to that of the ϒ(1S). A first measurement of the ϒ(3S) has also been performed. Finally, results are compared with previous ALICE measurements in p–Pb collisions at √sNN = 5.02 TeV and with theoretical calculations.publishedVersio

(Anti-)deuteron production in pp collisions at 1as=13TeV

The study of (anti-)deuteron production in pp collisions has proven to be a powerful tool to investigate the formation mechanism of loosely bound states in high-energy hadronic collisions. In this paper the production of (anti-)deuterons is studied as a function of the charged particle multiplicity in inelastic pp collisions at s=13 TeV using the ALICE experiment. Thanks to the large number of accumulated minimum bias events, it has been possible to measure (anti-)deuteron production in pp collisions up to the same charged particle multiplicity (d Nch/ d \u3b7 3c 26) as measured in p\u2013Pb collisions at similar centre-of-mass energies. Within the uncertainties, the deuteron yield in pp collisions resembles the one in p\u2013Pb interactions, suggesting a common formation mechanism behind the production of light nuclei in hadronic interactions. In this context the measurements are compared with the expectations of coalescence and statistical hadronisation models (SHM)

Multiplicity dependence of inclusive J/psi production at midrapidity in pp collisions at root s=13 TeV

Measurements of the inclusive J/psi yield as a function of charged-particle pseudorapidity density dN(ch)/d eta in pp collisions at root s = 13 TeV with ALICE at the LHC are reported. The J/psi meson yield is measured at midrapidity (vertical bar y vertical bar <0.9) in the dielectron channel, for events selected based on the charged-particle multiplicity at midrapidity (vertical bar eta vertical bar <1) and at forward rapidity (-3.7 <eta <-1.7 and 2.8 <eta <5.1); both observables are normalized to their corresponding averages in minimum bias events. The increase of the normalized J/psi yield with normalized dN(ch)/d eta is significantly stronger than linear and dependent on the transverse momentum. The data are compared to theoretical predictions, which describe the observed trends well, albeit not always quantitatively. (C) 2020 European Organization for Nuclear Research.
