For each structural and functional design of the organizational system, it is necessary before the start of design to know which is the highest hierarchical principle for the organization. The paper presents the results of research that give an answer to the question "What is the highest hierarchically principle for QMS in profit-oriented organizations?". Presented the highest hierarchical principle is explored for the purpose of orientation of quality management system in profit-oriented organizations. Defined principle should be used for the decomposition of lower hierarchical principles and objectives (6.2, ISO 9001: 2015). Defined principle enables the necessary integration of quality management systems in the business system of profit-oriented organizations.

The article discusses the concept of "human development" and the schematic diagram of the organizational design of regional management systems in relation to human development. Management as an organizational process in the study is considered as part of all social subsystems, specifies regularities of development and formation of new structures and functions. In the study applied the following methods: allocation of levels of models, techniques of domination, the allocation phases of the operation, the construction of generalized indicators, etc. As a result of research design problems of systems management human development revealed that the primary means of successful adaptation of organizations to changing conditions is an effective mechanism for management of human capacity, which will provide the best in current economic terms the end results that allows you to apply the concept of "innovation potential" in relation to the process of human development.

Personal values are seen as a higher level of attitudes and they reflect the general view on life and the world, dispositions aimed for achieving goals that are desirable and valuable for human- universal values in the structure of human personality that it strongly and permanently run on certain activities. It is found that ethical behavior have long been associated with personal values and that personal values in personal value systems of universalism, benevolence, tradition, conformism, security and independence are positively and significantly correlated with ethical behaviour, whereas universal values in personal value systems of power, achievement, hedonism and incentive are negatively and significantly correlated with ethical behaviour. This study presents the results of empirical research on personal value systems and ethical / unethical behavior among hotel strategic managers in large hotel companies in Croatia.

The paper exhibits the examination of life quality evaluation of helical coil springs in the railway industry as it impacts the safety of the transportation of goods and people. The types of spring considered are: the external spring, internal spring and stabiliser spring. Statistical process control was utilised as the fundamental instrument in the investigation. Measurements were performed using a measuring tape, dynamic actuators and the vernier caliper. The purpose of this research was to examine the usability of old helical springs found in a railway environment. The goal of the experiment was to obtain factual statistical information to determine the life quality of the helical springs used in the railroad transportation environment. Six sigma advocacies were additionally used as a part of this paper. According to six sigma estimation examination only the stabilizers and inner springs for coil bar diameter met the six sigma prerequisites. It is reasoned that the coil springs should be replaced as they do not meet the six sigma requirements.

Control charts for range (R-chart) and standard deviation (S-chart) are commonly used charts along with X-bar control chart for variables. One of the major challenges in these charts is the use of appropriate estimators of the unknown population parameters involved in the control limits. In this paper, first a detailed review on the classical charts for dispersion, R-chart and S-chart, is presented and then by applying the concept of Six Sigma quality characteristics, new set of Six Sigma-based R- and S-charts are developed. The motivation of the proposed approach is due to the fact that "specifications refer to the deviations that are permissible from the target and the units produced from a well-behaved process will match the target and standard deviation associated with its specifications". Accordingly, unlike the traditional charts, in this new approach, the unknown population standard deviation related to range and standard deviation are derived from specification using the perspective of Six Sigma. Procedures for obtaining control limits of the proposed Six Sigma-based R-and S-chart are given. The average run length values for the proposed new charts are also obtained for different in-control and out-of control shift values. It is discussed that due to various reasons a process may maintain certain sigma quality level at a point of time that may be in terms of number of sigma. Since the goal of Six Sigma is of 3.4 defects per million opportunities, it is recommended to keep monitoring the process in terms of sigma quality level by using the improved control limits for the purpose of continuous quality improvement every time till the goal is achieved. The proposed charts are illustrated with appropriate numerical examples for better understanding.

The purpose of this paper is to investigate the scope of reliability improvement of aluminium wire rolling mill. This paper addresses the performance reliability of continuous process industry of interest to many applications in maintenance planning where multi-attribute decision making (MADM) approaches are very useful. The paper addresses the process of discriminating critical components through substantial shop-floor failure data. The research work narrates a method for evaluating risk priority number (RPN) traditionally. Moreover, the maintainability criticality index (MCI) for each failure cause of identified critical components is evaluated through two disparate MADM failure models: technique for order preference by similarity to ideal solution (TOPSIS) and preference section index (PSI) to overcome the limitations of more traditional approaches. The primary findings of this research work are to enhance quality in planning the maintenance activities of critical components of targeted process industry through traditional as well as non-traditional failure analysis models. The research work is focused on potential failure causes of critical components like; bearings, gears, and shafts of aluminium wire rolling mill which are commonly representing the most critical components in a large range of industrial processes including aluminium wires. The proposed work will illustrate the working lives of components and associated failures. It will help to elucidate maintenance issues of major process industries and recommended deliverable keys.
