The article considers the components of the target function of optimization of HUNDRED losses associated with the introduction of the post (posts) of acceptance-diagnosis with the increase of the set of diagnostic equipment. In particular, the target function of optimizing losses at the service station is presented in the form of an economic criterion that takes into account the maximum possible number of components on which depends the technological efficiency of the service station and the level of "satisfaction" of car owners with services. The object of research is a car service station. The purpose of the work is to conduct a study of the target function of optimization of HUNDRED losses associated with the type of organization of acceptance-diagnosis of cars and to find out algorithms for finding the components of the target function based on the representation of HUNDRED as a queuing system. Research method - analysis and formalization: quantitative indicators of the objective function, methods of forming a group of events, alternative solutions and calculation of the main components of optimization of HUNDRED losses as a queuing system. It is established that the target function of optimization of HUNDRED losses has economic essence and can be presented in the form of complex criterion. It is found that based on the theory of queuing for the area of reception-diagnosis it becomes possible to find solutions of the system of equations that describe its current state, namely: 1) the probability that the system has no requirements, ie free all "workers »Posts and no applications in the queue; 2) the probability of finding the system in a certain state; 3) the probability of denial of the received application for maintenance, ie the probability of finding the system in the last valid state; 4) the average number of occupied reception posts. Similar solutions were found for the TO-R zone. The formulas for determining the components of the duration of the application are considered and given. The formulas for determining the average value of the duration of work in the area of maintenance by the flow of faults and their share in the total flow of applications. The necessity of the 5th - 6th step of building the equipment in the reception-diagnostic area for detection of additional malfunctions (hidden defects) is substantiated. It is established that the average processing time of the application at the posts of acceptance-diagnosis includes three components: 1) the average time of acceptance-diagnosis of the declared ambiguous manifestation of the fault; 2) the average time of additional preliminary diagnosis on the application, which contained ambiguous manifestations of malfunctions. Depends on the number of diagnostic operations performed and the available equipment; 3) the average time of additional diagnosis on the application, which either did not contain ambiguous manifestations of malfunctions, or they did not fall within the capabilities of the existing diagnostic complex at the reception. The results of the article can be used to model the operation of the service station as a queuing system in computer software products and will reveal the low efficiency of diagnosing the main systems of cars in a particular service station.

The Relationship

For the first time the mathematical model of task optimization for this scheme of cutting logs, including the objective function and six equations of connection. The article discusses Pythagorean area of the logs. Therefore, the target function is represented as the sum of the cross-sectional areas of edging boards. Equation of the relationship represents the relationship of the diameter of the logs in the vertex end with the size of the resulting edging boards. This relationship is described through the use of the Pythagorean Theorem. Such a representation of the mathematical model of optimization task is considered a classic one. However, the solution of this mathematical model by the classic method is proved to be problematic. For the solution of the mathematical model we used the method of Lagrange multipliers. Solution algorithm to determine the optimal dimensions of the beams and side edging boards taking into account the width of cut is suggested. Using a numerical method, optimal dimensions of the beams and planks are determined, in which the objective function takes the maximum value. It turned out that with the increase of the width of the cut, thickness of the beam increases and the dimensions of the side edging boards reduce. Dimensions of the extreme side planks to increase the width of cut is reduced to a greater extent than the side boards, which are located closer to the center of the log. The algorithm for solving the optimization problem is recommended to use for calculation and preparation of sawing schedule in the design and operation of sawmill lines for timber production. When using the proposed algorithm for solving the optimization problem the output of lumber can be increased to 3-5 %.

Well Placement Optimization

Abstract In reservoir development plans, well placement optimization is usually performed to better sweep oil and reduce the amount of trapped oil inside reservoirs. Long term optimization of well placement requires multiple times simulation of reservoirs which makes these problems cumbersome, especially when a large number of decision variables exist. Cumulative oil production (COP) or net present value (NPV) functions are commonly used as the objective function of optimal enhance oil recovery projects. Use of these functions requires a full-time reservoir simulation and their convergence could be difficult with the chance to be trapped in local optimum solutions. In this study, the novel proportionally distributed streamlines (PDSL) target function is proposed that can be minimized to reach the optimal well placement. PDSL can be estimated even without full time reservoir simulation. PDSL tries to direct the appropriate number of streamlines toward the regions with larger amount of oil in the shortest time and hence can improve oil recovery. Particle swarm optimization (PSO) method linked to an in-house streamline-based reservoir simulator is implemented to optimize well placement of water flooding problems in a 2D heterogeneous reservoir model.

Characteristic Features

Methods of landscape analysis are developed to estimate various characteristic features of the objective function in the optimization problem. The accuracy of the estimates largely depends on the chosen method of experiment design for the landscape sampling, i.e. on the number and location of points in the search space forming a discrete representation of the objective function landscape. The method of information content is the most resistant to changes in the experiment design but requires route building to bypass the obtained points of landscape sampling. A method of characterization of the optimization problem objective function is proposed on the base of landscape sampling without building a route to bypass its points. The notion of a variability map of objective function is introduced. The informativeness criteria are formulated for groups of points of a landscape sample. A method of constructing the so-called full variability map is proposed as well as the function of generalized information content for the analysis of the characteristic features of the objective function. The method allows obtaining more accurate estimates of target function characteristics which are resistant to variations of the experiment design

In the paper the way of adaptation of the penalty function method to the genetic algorithm is presented. In case of application of the external penalty function, the penalty term may exceed the value of the primary objective function. This means, that the value of the modified objective function is negative, while in genetic algorithm the adaptation must be of positive value, especially it in the selection procedure utilizes the roulette method. The sigmoidal transformation is applied to solve this problem. The computer software is developed in the Delphi environment. The proposed approach is applied to optimization of the electromagnetic linear actuator.

This article is dedicated to the publication and the comparative analysis of 11 – 12 centuries Pereiaslavl (modern name Pereiaslav) cranial series found during excavations by D. Samokvasov (1877), V. Shcherbakivskyi (1914), and a permanent archaeological expedition of the National Historical and Ethnographic Reserve «Pereyaslav» under the leadership of M. Tovkailo (2004 – 2007), D. Teteria (2008 – 2012), M. Rozdobudko (2014 – 2016), O. Priadko (2015 – 2019). The purpose of the article is to introduce a new material into scientific domain, provide a general description of Pereiaslav population of 11th – 12th cent. on the background of neighboring ethnic groups from Ukraine and Eastern Europe (synchronistic method), determine the distance between separate cranial series of 11th – 12th cent. with the help of multidimensional canonical and cluster analysis, and to find out the place of 11th – 12th cent. Pereiaslav male population in the system of craniological types of Eastern Europe. This paper attempts to apply two typological approaches to the researched group. The methodology of the research. The research is based on the principles of historicism and objectivity, general scientific (analysis and synthesis), historical (comparative-historical), anthropological and statistical methods were used. The skulls were measured according to the full craniometric program using the standard R. Martin method, according to which the numbering of signs was indicated. Computer software developed by B. Kozintsev and O. Kozintsev in 1991 has been used in the research. 14 craniometric traits defined by R. Martin have been involved into the study. Scientific novelty of the work is that for the first time, the general male Old Rus selection of Pereiaslav town including 59 skulls has been created. According to the craniometric trait average value, the male part of the series can be classified as dolichocranic Caucasoid variant with moderately broad face. It has been proved that after uniting two male craniological groups from Pereiaslav, its representatives, according to typological scheme by T. Alekseeva, belong to dolichocranic, middle size face craniological type. This is the same type where Siverians, Dregoviches, Smolensk Krivichs, and Radimichs belong to. Grounding on V. Diachenko typology, the male group can be classified to some extend as Neopontic craniological type. Conclusion. The comparison of the male researched group from 11th – 12th cent. with synchronic series from Old Rus territory with the help of multidimensional canonical and cluster analysis has shown its similarity to town series from Liubech, Halych and to less extend Chernihiv.

The Impact

This article discusses several issues related to intellectual capital, including a historical review, interest in elusive and intangible assets, and the impact of recent technological progress related to the development of information technology. Ralph Styer, CEO of Johnsonville Foods Company, was the first to use the term “intellectual property” to refer to an organization’s intangible assets. This document also defines the concept of intellectual property, which is the totality of all the knowledge that organizations have that helps them achieve their goals. Intellectual property includes ideas, inventions, technologies, general knowledge, computer software products and programs, projects, data skills, processes, creativity and applications in all organizations. Intellectual capital is knowledge that can be converted into profit. The components of this concept were defined as follows: structural capital, human capital, social capital and psychological capital. The article also discusses various definitions presented by a number of scholars related to intellectual capital, including: Edvinsson & Malone, K.E. Svieby, Y. Malhorta, T. Stuart, Depres and Channel, as well as Mackenzie and Winkelen. The article concludes that specific issues regarding companies and the nature of the market do not allow for certain results that can be generalized by comparing modern administrative trends or attitudes that define intellectual capital as intangible assets.
