Flexible manufacturing shop is examined. Multilevel control system of the shop is built. The demands to the system construction are listed. The existing input information is insufficient for building of the inventory model, for choice and realization of the optimal model of the manufacture. By this reason the situation of the uncertainties is arise. For the purpose to find needed data and to receive necessary knowledge the following intelligence procedures are suggested: ”Pendulum” – for stock foundation and for construction of the inventory model, “Symmetry in the arithmetical progression” – to define the values of the coefficients with unknown quantities in the aim function of the optimal task. With the help of the procedure “Pendulum” the equal corteges of the quantum of time are building. Cortege of the quantum of time is the unit of the stock and the direction for selection of the kind of the optimization model. The optimization model of location is suggested to use. Building of the indicated models (they are small dimension and equal dimension) give the opportunity to organize the parallel calculations.

В настоящей статье предпринята попытка исследовать отдельные проблемные аспекты института потерпевшего в российском уголовном процессе. В этих целях подвергнуты анализу правовые нормы, регламентирующие его процессуальный статус. Раскрываются отдельные пробелы уголовно-процессуального законодательства в сфере защиты законных прав и интересов потерпевшего. Автор акцентирует внимание на том, что совершенствование уголовно-процессуального законодательства в части расширения правомочий потерпевшего по отстаиванию своих нарушенных преступлением прав следует продолжить. На основании проведенного исследования действующего законодательства в части регламентации прав потерпевшего от преступления предлагается расширить перечень получаемых им копий постановлений, указанных в п. 13 ч. 2 ст. 42 УПК РФ. Автор предлагает включить в перечень указанной законодательной нормы право получения потерпевшим копии постановления об избрании конкретного вида меры пресечения, избранного в отношении подозреваемого (обвиняемого). Для создания действенного механизма защиты интересов потерпевших от преступления юридических лиц предлагаем ч. 9 ст. 42 УПК РФ изложить в следующей редакции: «в случае признания потерпевшим юридического лица его процессуальное право в уголовном процессе осуществляет представляющий его профессиональный адвокат». This article attempts to investigate certain problematic aspects of the institution of the victim in the Russian criminal process. For this purpose, analyzed the individual norms governing his procedural status. Separate gaps of the criminal procedure legislation in the sphere of protection of the legal rights and interests of the victim are disclosed. The author emphasizes that the improvement of the criminal procedure legislation in terms of the extension of the victim’s authority to defend his rights violated by the crime should be continued. On the basis of the study of the current legislation regarding the regulation of the rights of the victim of a crime, it is proposed to expand the list of decisions received by him, referred to in paragraph 13, part 2 of article 42 Code of Criminal Procedure. The author proposes to include in the list of the indicated legislative norm the right to receive the victim a copy of the decision on the selection of a specific type of preventive measure, selected in relation to the suspect (accused). To create an effective mechanism for protecting the interests of legal entities victims of a crime, we offer part 9 of art. 42 of the Code of Criminal Procedure of the Russian Federation shall be reworded as follows: «if a legal entity is recognized as a victim, his procedural right in criminal proceedings is exercised by the professional lawyer representing him».

Since application of integrated energy systems (IESs) has formed a markedly increasing trend recently, selecting an appropriate integrated energy system construction scheme becomes essential to the energy supplier. This paper aims to develop a multi-criteria decision-making model for the evaluation and selection of an IES construction scheme equipped with smart energy management and control platform. Firstly, a comprehensive evaluation criteria system including economy, energy, environment, technology and service is established. The evaluation criteria system is divided into quantitative criteria denoted by interval numbers and qualitative criteria. Secondly, single-valued neutrosophic numbers are adopted to denote the qualitative criteria in the evaluation criteria system. Thirdly, in order to accommodate mixed data types consisting of both interval numbers and single-valued neutrosophic numbers, the TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) method is extended into a three-stage technique by introducing a fusion coefficient μ. Then, a real case in China is evaluated through applying the proposed method. Furthermore, a comprehensive discussion is made to analyze the evaluation result and verify the reliability and stability of the method. In short, this study provides a useful tool for the energy supplier to evaluate and select a preferred IES construction scheme.

The aim of the study is to optimize the comprehensive treatment of patients with severe arterial hypertension, through the use of multicomponent rational antihypertensive pharmacotherapy, followed by the use of unloading therapeutic exercises. 32 men with severe arterial hypertension were examined. Initially, a clinical, instrumental and laboratory examination, registration of blood pressure and its 24-hour monitoring were carried out. The average daily systolic (ADBPsyst.) and average daily diastolic (ADBPdiast.) blood pressure were determined. A multicomponent rational antihypertensive pharmacotherapy, according to the clinical recommendations for the treatment of arterial hypertension was selected for all the patients. In at least 3 months after the selection of pharmacotherapy, the patients were divided into two groups, comparable in gender, age, severity of the condition, features of the disease course and medicamentous therapy. Patients of the 1st group (active treatment group) against the background of pharmacotherapy were prescribed unloading therapeutic exercises according to a patented technique. The 2nd group of patients continued to take pharmacotherapy and it was used as a baseline group. The average age in the 1st and 2nd groups was 46,3±6,8 and 43,6±7,2 years, respectively. Patients of the 1st group were prescribed unloading therapeutic exercises and in 3 months in both groups the ADBPsyst. and ADBPdiast. were compared. Initially, there was a significant increase in ADBPsyst. and ADBPdiast. compared to the normal range in both groups. These indicators in both groups differed insignificantly. In 3 months after pharmacotherapy, there was a significant decrease in ADsyst. and ADdiast. in both groups, but these indicators remained elevated and did not reach the target level. Then, in the 1st group, unloading therapeutic exercises were included in the comprehensive treatment. Patients of the 2nd group continued to receive pharmacotherapy. In 3 months after including unloading therapeutic exercises in the 1st group, there was a significant decrease in ADBP (syst. and diast.) not only in comparison with the initial data, but also with the data in 3 months after pharmacotherapy. In the 2nd group, these indicators did not change significantly compared to the three-month data. In 6 months, ADBPsyst. and ADBPdiast. in the 1st group were significantly lower compared to similar indicators in the 2nd group, which proves significant clinical effectiveness of unloading therapeutic exercises in patients of the 1st group. The results obtained confirm that patients with severe arterial hypertension have such types of disorders at the cellular-tissue and microcirculatory level that are not eliminated only by drug therapy. For their high-grade correction, along with multicomponent pharmacotherapy, it is necessary to include unloading therapeutic exercises. To optimize the treatment of severe arterial hypertension against the background of receiving multicomponent antihypertensive pharmacotherapy, it is recommended to include unloading therapeutic exercises in the therapeutic complex.

Purpose To receive a satisfactory consultancy service, a construction client must first select suitable consultants. While numerous criteria for the selection of construction consultants have been suggested in the literature, their influence on client satisfaction has hardly been statistically established. This study aimed to reduce the criteria for the selection of construction consultants into a more manageable set of fewer factors and ascertain the influence of the factors on client satisfaction. Design/methodology/approach Data were gathered through a purposively administered cross-sectional survey of public sector clients in Nigeria. Analyzes were done using relative importance index, factor analysis and multiple regression analysis. Findings The results proved that the criteria for the selection of consultants can, in the order of decreasing influence on client satisfaction, be grouped into service delivery approach (SDA), relationship with the client, the caliber of personnel, firm reputation and firm certification. However, SDA is more influential on client satisfaction. All the factors were found to have significant statistical effects on clients’ overall satisfaction with consultancy services. Originality/value The study demonstrates the extent to which construction consultant selection criteria are relevant to client satisfaction. It shows that SDA is the most important predictor of clients’ satisfaction with consultancy services. The results are helpful for grouping consultant selection criteria in future studies, and in guiding clients on the weights to assign to consultant selection criteria during tender evaluation.

This chapter focuses on the deadlock prevention problems in Flexible Manufacturing Systems (FMS), and the major target is to design more excellent controllers that lead to a more permissive supervisor by adding a smaller number of monitors and arcs than the existing ones in the literature for the design of liveness-enforcing Petri net supervisors. The authors distinguish siphons in a Petri net model by elementary and dependent ones. For each elementary siphon, a monitor is added to the plant model such that it is invariant-controlled without generating emptiable control-induced siphons, and the controllability of a dependent siphon is ensured by changing the control depth variables of its related elementary siphons. Hence, a structurally simple Petri net supervisor is achieved. Based on the previous work, this chapter explores two optimized deadlock prevention approaches based on elementary siphons that can achieve the same control purpose and have more excellent performance.
