Under conditions of increasing of industrial consumption of sugar in Russia and applying specific requirements for sugar as primary commodity, issues of flexibility and readjustment of process lines for production of sugar of prescribed properties become relevant. Maintaining the quality and safety of products in this case can be ensured by the transition of the process control system to a new paradigm, including the improvement of tools in the form of measurement methods. As a basis for the methodology of forming the system of control methods, three principles have been proposed: the package principle, the acquisition of standard and extended case methods, and the unification of methods presentation. The package principle as a tool of the rule-making methodology, with its detailed elaboration in standardization, has been considered in detail. It is shown that in order to ensure the compatibility of operational control methods, it makes sense to provide unified approaches to their development, essential content, construction and presentation, which is possible by adopting the package principle used in standardization. The necessity of expanding the nomenclature of control parameters of the technological flow of sugar production was considered in detail; the existing prerequisites were shown. It was proposed to provide the implementation of nomenclature variations of control parameters on the basis of the formation of two case methods, differentiated according to the destination of the sugar produced - for population or industrial consumers. It is noted that control parameters of the technological flow of sugar production are the quantities related to the subject of quantitative chemical analysis, the practical side of which is reflected by analytical methods. Due to the current variety of attributes of methods presentation, their harmonization is required both by means of the unification of the presentation of measurement methods of the same parameters for different control objects according to their substantive essence, and by means of the unification of the text presentation of the methodology. The principles considered together constitute the essence of the methodological approach to the formation of the system of control methods of the technological sugar production flow.

This article presents an in-situ comparative analysis and power quality tests of a newly developed photovoltaic charging system for e-bikes. The various control methods of the inverter are modeled and a single-phase grid-connected inverter is tested under different conditions. Models are constituted for two current control methods; the proportional resonance and the synchronous rotating frames. In order to determine the influence of the control parameters, the system is analyzed analytically in the time domain as well as in the frequency domain by simulation. The tests indicated the resonance instability of the photovoltaic inverter. The passivity impedance-based stability criterion is applied in order to analyze the phenomenon of resonance instability. In conclusion, the phase-locked loop (PLL) bandwidth and control parameters of the current loop have a major effect on the output admittance of the inverter, which should be adjusted to make the system stable.

Definition Of

The main approaches to the methodology of staff incentive and engagement are considered in the article. The research aim is to develop theoretical and methodological provisions, methodological approaches to the formation, functioning and development of a staff incentive scheme. Today, economics has developed several contradictory approaches to the definition of a category “staff incentive scheme”, as a consequence of ambiguous understanding of such categories as “motive” and “stimulant”, “engagement” and “incentive”. The issue of the relation between these concepts has remained controversial. In management practice, these categories are not differentiated, they are considered rather as synonymous concepts. The author has summarized the views of economists on the essence of the “incentive” and “engagement” concepts. It has been determined that, most scientists proceed from the fact that engagement is a broader concept than incentive. The article examines the engagement process from the standpoint of the stimulant impact on the motive formation. Staff incentive in an organization is not only a process but also a system, therefore, defining the technological component of the methodology, the author considered it as a system and process at the same time. The article describes the structure of a staff incentive scheme in different types of social and labor relations. As a result of studying the genesis of social and labor relations and the conceptual fundamentals of management and engagement, society development and the scientific and technological progress, the author found that development of a theoretical and methodological approach to staff incentive is efficient and meets the requirements of a new paradigm of socio-economic systems. A theoretical and methodological approach to staff incentive has been offered. This approach differs in the concepts of incentive as a system and process in the formation and support of which the object of management together with the subject is involved. The worldview aspect of the methodology was formed as a result of the development of mechanistic, humanistic, socially-oriented and participative approaches to human resources management. The cognitive component of the methodology is shown in the development of theories which reflect this evolution: classical management theories, the concept of human relations, the concept of human resources, the concept of socially responsible and ethical management.

The purpose of this study is, using the example of sugar production, to identify parametric characteristics and relationships that make it possible to simulate an algorithm and assessment procedures for predicting the possible results of the economic activity of processing organizations in the context of unstable business relations with suppliers of beet raw materials. The developed methodological approach is based on the classification of factors and conditions by sources of occurrence (external, conjugate and internal environment). When modeling scenario and situational changes, the assumptions inherent in the law of “diminishing returns” were made. In particular, only units of the conjugate environment (beet losses during storage and transportation; sugar losses during storage and in production; conjugation coefficient) are presented as dynamic (subject to change) indicators, the rest are positioned as constants, justifiably unchanged in the short term. Approbation of the proposed valuation procedures made it possible to identify imbalances in the level of dynamics of the resulting indicators (specific profit from sales (per ton of product) and profitability of sales with deviations in the values of the conjugation coefficient of the relative base level characterizing the balance of business relations with suppliers. Based on the results obtained, a conclusion was made about the possibility of manifestation of the established disproportions and the effective use of the proposed methodological approach for their leveling in the subjects of other industries.

Dynamic Programming Problem

This paper proposes a Supervised Reinforcement Learning (SRL) algorithm for the Adaptive Cruise Control system (ACC) to comply with human driving habit, which can be thought of as a dynamic programming problem with stochastic demands. In short, the ACC problem can be deemed as the host vehicle adopting different control parameters (accelerations in the upper controller, brakes and throttles in the bottom controller) in the process of following or other driving situations according to the driver’s behavior. We discretize the relative speed as well as the relative distance to construct the two-dimensional states and map them to a one-dimensional state space; discretize the acceleration to generate the action set; and design additional speed improvement shaping reward and distance improvement shaping reward to construct the supervisor. We apply the SRL algorithm to the ACC problem in different scenarios. The results show the higher robustness and accuracy of the SRL control policy compared with traditional control methods.

This paper reports on a complex approach to including emotional engineering and system engineering in the development of a concept of a future product. The concrete problem was to develop a new product paradigm and a feasible concept of a branded motorcycle for 2020. The new product paradigm has been developed by considering some trend-setter new developments in the field of driving, moving, and control systems for motorcycles. Emotional engineering was used to include the opinion of the potential users in the formation of the new paradigm and to provide the users with comfort, pleasure, and emotional sensations. System engineering made it possible to find realistic solution elements for the implementation, and to develop a feasible product concept based on this paradigm that fulfils the functional, utility, and emotional expectations of the users. The information and knowledge intensive sub-processes of emotional and system engineering have been supported by design inclusive research. This methodological approach included the evolving product paradigm, and its various representations and prototypes as a research means. Design inclusive research consisted of an exploration research part, a concept and prototype development part, and a confirmative research part. Using this framing methodology, designers can get a better idea of what preferences their target groups have and understand what can be successful on the market. The results achieved are being used as input for further strategic investigation by the concerned companies.

The Stability

Based on the stability and orthogonal polynomial approximation theory, the ordinary, dislocated, enhancing, and random feedback control methods are used to suppress the Neimark-Sacker bifurcation to fixed point in this paper. It is shown that the convergence rate of enhancing feedback control and random feedback control can be faster than those of dislocated and ordinary feedback control. The random feedback control method, which does not require any adjustable control parameters of the model, just only slightly changes the random intensity. Finally, numerical simulations are presented to verify the effectiveness of the proposed controllers.

Value Measurement

This paper addresses the issues of methodological problems and limitations regarding measuring values. A short scan review of values measurement methods from psychological and ethnobotanical approaches was made to enumerate some of those shortcomings. A new methodological approach, named Kab’s Value Survey (KVS) was proposed and compared with other well adopted methods based on some important criteria to assess its suitability, uniqueness and novelty. The results of the comparisons shows that KVS for its considerations to the theoretical explanations distinguishes itself over other methods of value measurement in the sense that the methodological approach employed is more broad in scope and applications, simple, specific and reliable in terms of instruments for data collection, psychometric data analysis, and of course data presentation. The method however solved some of the criticized limitations that exist in other well adopted methods of values measurement from psychological and ethnobotanical perspectives.

ABSTRACT In March 1986 an unknown quantity of paraffin-based oil and brine was spilled in the Sam Houston National Forest, San Jacinto County, Texas. The source of the spill was a ruptured production flow line. A tributary to the East Fork of the San Jacinto River and 12.5 acres of the forest were affected by the spill. Mitigative options were evaluated for speed and environmental acceptability. Two atypical control methods were selected: freshwater flushing in areas principally affected by brine, and controlled burning in oil-saturated areas. These techniques provided rapid control of the contaminants and exerted the least additional stress on the forest. Restoration methods were suggested after the initial mitigation of the spill by burning and flushing.
