Optimal Approach

Machining of different materials brings increasing of productivity, economical effectivity and quality of work piece. Constant development of Robotics and information systems brings new views of using robots in a process of production. Instead of using robots for a purpose of manipulation with work pieces, it is possible to use a robot directly for machining. Robotics machining technology has its advantage in application, which represents an adequate alternative in machining of metals on tradition of machine systems. The aim of the suggested plan of the experiment is to identify the optimal approach and combinations of each parameter during milling.

Information technology (IT) has radically improved many aspects of organisational activities. Computer-based information systems (CBIS) are constantly developed more effective and efficient. Development of a new CBIS is justified by higher quality of work, more efficient work processes, and more flexible work practices. However, introduction of the new IS can produce a variety of problems. This paper describes the problems observed in the use of a library CBIS in a Finnish scientific library. The results of the study illustrate well the environment which should be understood by the designers of computer-based information systems. One important prerequisite of good (re)design is a wide understanding of the problems that may prevent effective use of a CBIS. In this study we introduce a classification based on the problems which were found in the case. The classification describes the causes and effects of the observed problems.

Information Systems Quality

Usability is one of the characteristics that compose the multi-dimension concept of information systems' quality. Technology improvements enable the building of information systems to be used "any place, any time", through mobile handheld devices and wireless networks. Usability is threatened by the use of mobile-wireless information systems, especially because of the use of small devices with tiny screens, the difficulty to operate and the use during mobility. Therefore, there is a need to measure the usability characteristic, in order to define the level of quality of such information systems. This paper introduces the definitions of usability, and presents the definition of new metrics, defined in order to measure the quality level of usability of mobile-wireless information systems. These metrics were empirically validated using four different experiments, based on handheld devices.

The article describes the difficulties faced by organizations engaged in engineering and geodetic work at power plants, with participation in procurement. It is shown that the majority of procurement participants are representatives of small and medium-sized businesses. The factors affecting the reduction in the price offer are given. It is noted that a decrease in the initial (maximum) price during the procurement procedures varies from 75 to 90%, which cannot but lead to a decrease in the quality of work, and often to falsification of reporting documentation. Conclusions are made on the example of three realized purchases by the definition of the contractor for geodetic work at thermal power plants.

This article is the first in a series to celebrate the 70th anniversary of the ILR Review. We will be highlighting important research themes that have been featured in the journal over its many years of publication. In this article, Paul Osterman reviews research on the quality of jobs and recent debates over “High Road” and “Low Road” approaches to employment practices. Scholars and policy advocates frequently utilize the distinction between High Road and Low Road firms as a framework for efforts to improve the quality of work in low-wage employers. This article assesses the logic and evidence that underlies this construct. The author provides a definition of the concept and examines the evidence behind the assumption that firms have a choice in how they design their employment policies. He then takes up the assertion that firms that adopt a High Road model can “do well by doing good” and adds precision to this claim by reviewing the evidence that a profit-maximizing firm would benefit from following the High Road path. The article concludes by suggesting a research agenda and providing a framework for policy that flows from the conclusions drawn from the existing research base.

In the context of the digital transformation of the economy, the effective development of corporate information systems of research and production holdings of aerospace instrumentation is becoming one of the decisive factors in ensuring the high quality of domestic avionics. This article is devoted to the analysis of the influence factor of digitalization and informatization processes in scienceintensive industries of modern aerospace instrumentation, as well as the definition of a qualimetric model for assessing its impact on the quality of domestic avionics products in the current economic and technological conditions. The influence of the level of development of corporate information systems of aerospace instrumentation enterprises on the quality of domestic avionics products is assessed in the article on the basis of the corresponding hierarchy of quality indicators. The proposed model of the influence of the level of development of corporate information systems on the quality of aerospace instrumentation products assumes the choice of the form of the integral criterion depending on the external requirements for the efficiency of the assessment, the sensitivity of the system of quality indicators.

As HR experts would propound, organizational success is highly dependent on attracting, recruiting, motivating, and retaining its workforce. The quality of work life (QWL) pertains to favourable or unfavourable work environment in keeping employees motivated so as to enable increase per capita productivity. It aims at achieving an effective work place environment that satisfies  both the organizational and personal needs and values of employees , promoting well being by job security,  job satisfaction, development and thereby helping to maintain a better  balance between work and non-work life. The word sustainability is derived from the Latin sustinere (tenere, to hold; sus, meaning up. Dictionaries provide more than ten meanings for sustain, the main ones being to “maintain", "support", or "endure”. However, since the 1980s sustainability has been used more in the sense of human sustainability on planet Earth and this has resulted in the most widely quoted definition of sustainability as a part of the concept sustainable, that of the Brundtland Commission of the United Nations on March 20, 1987: “sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their needs.

Quality of work is a core element of the European social model. In this article we analyse the role and instruments of EU actors in this policy area in order to discover the extent to which it has been institutionalized since the mid-1990s. We first demonstrate that quality of work has to be understood as a multi-dimensional concept, before analysing the respective roles of and interactions between the Council, the Commission, the European Parliament and the social partners. Both the definition of the subject as a policy problem and the construction of a comprehensive indicator-based monitoring tool represent necessary, albeit not sufficient, steps to promote the quality dimension of work. The article is based on document and secondary literature analysis as well as expert interviews.

Some effects come into the practice because of decreasing quality of a cutting knife. These effects then influence the whole cutting process. The paper deals with analysis of methods for evaluation of a chain saw wearing. It is necessary to know the methods for measurement of a chain saw wearing because the tool wearing has significant influence on the whole system acting i.e. machine-tool-work piece. The measurement of wearing rate was realized to obtain knowledge about the wearing rate of cutting knives on chain saws. The goal of measurement was to design suitable methods for evaluation of wearing and definition of exactness for used methods. The exactness of used methods is evaluated according to the range of variance. The cutting knife wearing was analyzed by two methods; the results of both methods were compared. In the future it would be very effective to generalize mentioned methodology for measurement of a cutting knife wearing.
