Competitiveness of an IT Provider: from benchmarking and “Best Practices” to models and management mechanisms
Authors: Zimin A V , Burkova I V , Zimin V V , Ivushkin A A 
Published: August 2021

Abstract
The paper proposes the development of the approach described in the ITIL-3,4 library to the formation by an IT provider of competitive IT assets (called “best practices”). The ITIL mechanism provides for regular benchmarking in order to determine the composition and values of indicators of critical factors for the success of the market area and the formation by the IT provider by methods of the theory of asset management, the functioning of which ensures the achievement/superiority of market values of these indicators. The difference between the proposed approach consists in replacing the “best practices” of management with procedures for solving optimization and game problems, the mathematical models and control mechanisms of which are based on mathematics, control theory, decision theory and game theory. The proposed approach makes it possible to overcome such disadvantages of “best practices” as the averaging of the conditions for their application and their insufficient efficiency. This is achieved due to the multivariate formulation of control problems, and the multi-structure and optimality of control mechanisms. In conclusion, it is indicated that it is legitimate to consider the developed models and management mechanisms as a separate new type of IT provider assets.

Corporate rent and its role in replication of regional resource dependence
Authors: Kavkaeva O N , Goosen E V , Nikitenko S M 
Published: August 2021

Abstract
For countries with significant natural resources, the process of distributing and managing rents plays a key role. For a long time, the influence of rent on the development of territories was assessed by comparing the dynamics of the growth rates of the gross domestic product of countries with resources and countries without natural resources-a macroeconomic approach. The criticism of this approach is well known. Much less studied is the microeconomic aspect of this problem-how a company extracts rent and how the method of withdrawing and disposing of corporate rent (excess income received by an individual company) affects the development of its host regions. The so-called resource regions are experiencing the greatest negative impact. At the same time, it is the activities of large mining companies that lead to a stable replication of the resource capacity of the economy-the dependence of the country’s well-being on income from the extraction and export of natural resources. The purpose of this article is to describe the mechanisms of extraction and distribution (corporate rent) at the level of mining companies and assess the impact of these processes on the host regions. PJSC Gazprom, PJSC Lukoil, OJSC UGMK, JSC SUEK were selected as examples. The choice of companies is due to their role in the relevant sectors of the fuel and energy complex, as well as the pronounced multidirectional influence of these companies on the regions. The methodological basis of the article is the concept of value chains. It is shown that the mechanisms for extracting and distributing corporate rent at the level of mining companies have a significant impact on the regions where they are based. The search for ways of optimal distribution and effective impact of natural rent on the development of resource regions through the formation of new value chains is proposed as a “treatment”. Interaction scenarios can be different: interaction with scientific and educational institutions or the creation of scientific and educational centers. It is proposed to stop special attention on the formation of new manufacturer-controlled value chains based on cooperation with vertically integrated companies.
Innovative component of the transformation of resource-based regions

Published: August 2021

Abstract
The problem of changing the extensive model of economic development in Russia is directly related to the willingness of resource regions to move to the trajectory of balanced development. Therefore, the question of developing approaches and algorithms for assessing the readiness of resource regions for the development of technologically interconnected industries focused on the production of products with high added value is relevant. The solution to this issue is connected both with the selection of the most informative indicators, on the basis of which an assessment of this readiness can be made, and with a strong differentiation of resource regions. The purpose of the article is to study the possibility of a comprehensive assessment of the readiness of resource regions for the development of technologically interconnected industries focused on the production of products with high added value based on their investment and innovative activity. To solve the problem, the article presents and analyzes statistical information on investment and innovation activity of the studied group of regions for the period 2010-2017. The performed analysis allows us to conclude that the studied group of regions has significant heterogeneity. As an explanation of the causal mechanism, there are two main versions of the resource curse theory. They can be conditionally called “economic” and “political” resource curse. In the first, the so-called crowding-out effect has a negative impact on economic growth (or, in our case, innovation)-a high return on investment in the extractive sector leads to a reduction in investment in other sectors. Within the second framework, resource rent causes a drop in the quality of public administration, which, in turn, negatively affects economic growth. Within the framework of our study, it is difficult to unambiguously draw a conclusion about the causal mechanism that determines a lower indicator of the “innovative activity” component with an increase in the resource dependence of the region, however, the effect of the “crowding out effect” is more likely.

Published: August 2021

Abstract
The features of the provision of transport and logistics services by road transport in the conditions of the Russian Federation are determined. The urgency of solving the issue of reducing costs by adjusting routes of cargo delivery by road transport is substantiated. It should be made taking into account the state of the resource allocation system of the road and transport infrastructure. An additional set of indicators is proposed, which allows the process of adjusting the routes of cargo delivery to be divided into three stages and taking it into account the state of the resource allocation system of the road and transport infrastructure. An algorithm is developed for adjusting the routes of cargo delivery, taking into account the state of the resource allocation system of the road and transport infrastructure. The problem of adjusting the routes of cargo delivery, taking into account the state of the resource allocation system of the road and transport infrastructure is solved. The proposed algorithm for correcting cargo delivery routes allows it to be used for solving the problem of multi-criteria choice optimization of the route option that best meets all the requirements declared by users of the road and transport infrastructure.

Published: August 2021

Abstract
The paper is a partial synthesis of the work that a team within the Faculty of Managerial and Technological Engineering has in the field of modeling and simulation of systems with Petri nets. The paper deals with three issues. The first part is Modeling and simulation of manufacturing systems with timed Petri nets. The first part presents the way in which the performances of some manufacturing systems are evaluated using timed Petri nets. The first example is a manufacturing system specific to the textile industry. The system has three production lines. In this case, the modeling with timed Petri nets allows the analysis of the operation of the flow lines and highlights the bottleneck. Another modeled manufacturing system is specific to a series production, more precisely it refers to the manufacture of gas cookers within a company from Oradea. The model with Petri nets also describes the supply sequences of the stocks of parts and subassemblies. The next modeled system is an automated manufacturing system for the packaging of detergents. The complexity of the Detergent Packing System and the high level of automation, require the use of efficient modeling and simulation methods to verify the validity of the solutions adopted. In this chapter is present the model of a robotic welding cell. The second part of the paper, the transition from timed Petri nets to hierarchical colored Petri nets, shows how Petri nets were developed for a robotic cell for metallographic analysis. The third part is dedicated to modeling with colored Petri nets timed with complex colors of the flexible manufacturing cell A007 within the Department of Industrial Engineering.

Authors: Gavrila C C , Lates M T 
Published: August 2021

Abstract
Minting metal coin, mean to impress a given relief model on both coin faces and also on the edge. Due to the high striking pressure, the round blank material is forced to fill the inner space between dies. In the past, for less coin value, the coin edge remained cylindrical, without any inscription. Following the increased coin value, it was introduced a security feature against forgery; on the coin edge model could be toothed or inscribed with relief or incuse text logo. Besides the coin edge basic design, a various amount of coin edge error types are released. In the paper there are studied some errors on the metal coin edge impressed with incuse text by punching. First, there are presented some particular examples and general aspects about the coin edge punching are also introduced. Then, the simplified 3D model of the parts is presented. Also, the finite element analysis on this model is realized and is achieved for different initial conditions. In the final part, the analysis results and conclusions are presented.
Oil condition monitoring and predicting actions using an Artificial Intelligence technique: Principal Components Analysis algorithm
Authors: Salem N. 
Published: August 2021

Abstract
Like other lubricants, oils play a crucial role in providing the space needed to separate moving parts. In addition, the lubricants ensure the suspension and transport of contaminants, neutralize corrosive acids, protect surfaces likely to wear, ensure heat dissipation, and provide the performance and increasing performance characteristics of industrial equipment and beyond. During use, lubricating oils undergo several chemical transformations due to oxidation at high temperatures (regime temperatures) due to degradation and contamination, water, ethylene glycol, coolants, waste residues. Finally, oils reach a lifetime due to a wide variety of degradation mechanisms, which lead to increased oxidation and nitration, base depletion, acid build-up, water contamination, cooling fluids, and viscosity changes. The rather complex nature of lubricants, along with the distinct variety of industrial equipment, especially the latest generation, equipped with high-performance techniques and artificial intelligence, make it very difficult, if not impossible, to predict all possibilities of generating defects. This study was intended to show how to expect action-time series data using Artificial Intelligence techniques on a set of data collected using direct/indirect sensors and computational determinations based on empirical relationships. The algorithm Principal Components Analysis (PCA) has been approached to predict the values of the next steps of any sequence by support vector machines (SVM) models. The PCA approach was considered a favourable experiment. The answers obtained characterize and equate the training sequences with values changed by a step of the time. This means that the data structure learns to predict the next step’s output value at each stage of the input sequence.
Choice of Offers by means of Multi-criteria Decision Systems, using Fuzzy Logic. Case Study
Authors: Prada A M , Blaga F S , Ursu M 
Published: August 2021

Abstract
This paper shows in detail the steps for the creation of an application in Matlab, using multi-criteria decision systems based on fuzzy logic. The aim of the application is to find the optimal offer for a client, based on the scores attained by simulation. In order to make the optimal offer in terms of quality and price for thermoplastic material parts, the main elements that are taken into account for the final price are cost of raw material, its quality and the price of the mould. The price of the raw material is mainly influenced by the annual necessary volume and by the project duration. The dimensions, the tolerances of dimensions, shapes and positions, the surface roughness, the coordinates of the critical points and the warranty of the mould have all a great influence on the price of the mould. This paper has two main chapters, of which the first one presents the selection procedure of an offer, and the definition of the multi-criteria decision systems that are used to evaluate the final offer, based on the accuracy of the choice for raw material and mould. The second chapter presents a case study which demonstrates the possibility to make such an application. The input quantities of the decision system must be carefully defined in order to attain results as coherent as possible.

Authors: Mitrea-Curpanaru G G L 
Published: August 2021

Abstract
The performance of an organization is determined by: its level of coherence and stability; its ability to procure and use resources; of his reputation and image; the synergy of multiplying determinants such as employee relations, communication, mission, philosophy and leadership style, recognition, quality of organizational processes. Performance is defined by behaviors, but especially by results. A mixed performance management model is concerned with both inputs and outputs. The selection of the best model to improve performance is based on a self-assessment process. The complexity of managing an organization today requires that managers be able to measure performance and analyze the impact of different dimensions of performance on organizational excellence. Many experts in the field have started talking about the importance of measurement as a means of communication. The institution’s performance is analyzed on the basis of key internal and external performance indicators, established targets and existing trends, judged constructively, with the establishment of improvement targets. Any performance measurement indicator is also used as a tool to control it, effectively for the implementation of continuous performance improvement actions.

Enhancement of the photovoltaic performance of dye-sensitized solar cell using porous silicon layer as photoelectrode
Authors: Gamal Y , Abdallah T , Youssef G M 
Published: August 2021

Abstract
Porous Silicon Dye-sensitized solar cell (PS-DSSC) with N719 Dye was employed as photoelectrode. PS layers were formed on textured crystalline silicon CZ-Si (100) by electrochemical etching (ECE) in hydrogen fluoride (HF) based electrolyte at constant current density for different etching times. The morphological properties of the PS were investigated by scanning electron microscopy (SEM). The optical properties of the textured surfaces are studied using photoluminescence (PL) and reflectivity measurements. The bandgaps of PS from UV-Vis and PL measurements increase to 1.9 eV. The Current-Voltage (I-V) characteristics show that the short-circuit current density Jsc and the open-circuit voltage Voc increased as the porosity of the PS layer increased. These results show an improvement in the efficiency of PS-DSSC.
