IMPACT OF BALANCED ORGANIZATIONAL VALUES ON BUSINESS PERFORMANCE
Ivan Malbašić, 2015, doctoral dissertation

Abstract: Theories of organization and management have offered several concepts and models indicating that organizational values are an important factor in running organizations. A still unexplained question concerns the creation of balanced organizational values which can support the achievement of diversified and even seemingly incompatible goals of today's organizations. To explore balanced organizational values in contemporary business practice, we tested two most frequently used value models, i.e., the Competing Values Framework and Schwartz’s values model, on the sample of the Fortune 100 companies. This dissertation proposes a new model of balanced organizational values named Mission-based model of organizational values which proved itself to be more appropriate for researching balanced values in contemporary business practice than the two most frequently used value models (the Competing Values Framework and Schwartz’s values model), thus supporting the first hypothesis of this dissertation. Given the particularities of balanced organizational values research, an instrument for measuring organizational values was developed to suit the specific needs of this research. In order to test the research hypotheses, a research in 24 Croatian companies was conducted. In each of these companies, between 27 and 50 employees were surveyed giving a total sample size of 874 respondents. The results of statistical analysis performed to test the second hypothesis, as well as the related sub-hypotheses, indicate that the degree of imbalance of organizational values has no significant effect on the higher level of organizational commitment. The same applies to the two separate components of organizational commitment—affective and normative. However, the existence of medium-sized negative correlation between the degree of imbalance of organizational values and continuance component of organizational commitment was determined. The testing results of the third hypothesis, as well as the related sub-hypotheses, indicate that organizations with balanced organizational values are, in general, more effective than organizations with imbalanced values. Moreover, this correlation was found not only for the overall level of organizational effectiveness, but also for the most perspectives of organizational effectiveness based on the Balanced Scorecard approach. To conclude, this dissertation contributes to a better understanding of the role of organizational values in business, especially emphasizing the importance and role of balanced organizational values. Mission-based model of organizational values, developed within this dissertation, follows the findings of the most used models, integrating and upgrading them with new cognitions based on selected scientific knowledge and experience from business practice. And most importantly, this dissertation presents an empirical confirmation of the importance of balancing organizational values as one of the preconditions for successful business.
Keywords: organizational values, balanced values, model of organizational values, business performance, organizational effectiveness, organizational commitment, Fortune 100 companies

Fuzzy Logic Model for the performance benchmarking of sugar plants by considering best available techniques
Damjan Krajnc, Miro Mele, Peter Glavič, 2007, original scientific article

Abstract: This paper deals with the problem of performance benchmarking of traditional beet sugar plants, by considering Best Available Techniques (BAT) for beet sugar production, as determined by the Integrated Pollution Prevention and Control (IPPC) Directive. A Fuzzy Logic Model, based on fuzzy set theory, was constructed for this purpose, in order to compare the performances of sugar plants within the sector's best standards, as expressed in the Reference Document on BAT. The effectiveness of the model was tested in the case study,in which three sugar plants were benchmarked against the BAT regarding the consumption of energy, water, raw materials and the production of wastes, wastewater, by-products and the main product. The model was recognized as helpful for the benchmarking needs of sugar plants. In addition, by integrating BAT Reference Document analysis into the model, it provides IPPC permitting authorities with an objective method and uniform BAT benchmarks to manage permitting process.
Keywords: chemical processing, beet sugar production, sugar industry, clean technologies, performance benchmarking, IPPC Directive, technology performance assessment, fuzzy set theory, best available techniques, IPPC permitting process

Optimization of a fuel injection system for diesel and biodiesel usage
Breda Kegl, Marko Kegl, Stanislav Pehan, 2008, original scientific article

Abstract: This paper presents an optimization procedure of a fuel injection system of a bus diesel engine. Attention is focused on the differences resulting from using two different types of fuel: diesel and biodiesel. The proposed design procedure relies on the assumption that the atomization of fuel spray influences the diesel engine performance, fuel consumption, and harmful emission significantly. As a measure of spray atomization, the Sauter mean diameter is employed and introduced into the objective function. The design problem is formulated in the form of a multiobjective optimization problem, taking into account the ESC 13 mode test for diesel engines of commercial vehicles. The design variables of the injection system are related to the shape of the cam profile, to the nozzle geometry, and to the control parameters influencing the injection quantity and timing. The geometrical properties of the cam profile and the injection parameters are kept within acceptable limits by the imposed constraints. The results of optimization using diesel and biodiesel are compared to each other to show the influence offuel type on final design and performance of the system.
Keywords: fuel injection system, diesel engine, biodiesel fuel, engine performance, numerical simulations

Analysis of innovation concepts in Slovenian manufacturing companies
Iztok Palčič, Borut Buchmeister, Andrej Polajnar, 2010, original scientific article

Abstract: Competitive advantages of manufacturing companies are not only generated by R&D based product innovations but also by technical and non-technical process innovations aiming to modernise manufacturing processes. This paper presents the use of selected innovation concepts in Slovenian manufacturing companies. Later we analyse the relationship of the use of selected technical and organisational innovation concepts and companies performance indicators. The results show that R&D expenses and innovation concepts are not always correlated and that there is a difference in innovation concepts utilisation between low, medium and high-tech industries. The data were obtained with The European Manufacturing Survey (EMS) that was conducted in 2009 within nine European countries. For the purpose of this paper we use data of Slovenian manufacturing companies.
Keywords: innovation, technical innovation, organisational innovation, company performance

INTERACTION BETWEEN QUALITY MANAGEMENT, PRODUCTION AND MAINTENANCE PERFORMANCE
Damjan Maletič, 2015, doctoral dissertation

Abstract: Many organisations invest a considerable amount of capital and resources, implementing new techniques to improve their performance. An effective management of production and maintenance and processes is vital for economic viability and a long term survival of many industries. In fact, an effective and efficient maintenance process is essential to assure asset performance. With this recognition, the asset and maintenance management has become an indispensable element of strategic thinking of asset owners and asset managers. This research aims to investigate the interaction between quality management, production and maintenance performance. The relevant theoretical foundations and research gaps are presented first, followed by development of a conceptual framework. The framework builds upon resource-based theory (RBT) literature to develop a conceptual framework, mainly to understand how company’s resources could contribute to company’s performance. Based on this theoretical underpinning two main research streams are studied, namely quality management in maintenance and asset management. Different sources of data were utilized to answer the proposed research questions. The thesis includes two large-scale surveys (among Slovenian organizations as well as an international survey conducted in Slovenia, Sweden, Poland, Slovakia, Greece and Turkey) and two empirical case studies. The outcome of regression analysis provides the evidence that quality management orientation is an important predictor of maintenance performance. By testing the impact of quality management orientation on maintenance performance, this research shows that strong foundation on quality management orientation is an effective way of improving maintenance performance. Further, by examining continuous improvement in relation to maintenance performance, this research seeks to examine the role of quality management practices in achieving maintenance performance. In this regard it was found that continuous improvement significantly and positively affects the maintenance performance. In addition, results of this research revealed a mediator effect of continuous improvement on the relationship between quality management orientation and maintenance performance. Moreover, this research examines the relationship between physical asset management practices and sustainability and operational performance as well. The research is based on a premise that asset management, which comprises of risk management practices, performance assessment practices, life cycle management practices, policy & strategy practices, leads to improved organizational performance. The results of this research provide the evidence to support the hypotheses and to demonstrate that organizations can benefit from the implementation of asset management practices. The MANOVA furthermore provides interesting insights into the effects of asset management practices on the organizational performance. The results indicate that there are significant mean differences in organizational performance dimensions (as measured by the business performance, environmental performance, social performance and operational performance) for low and high levels of asset management practices. Therefore, by focusing on asset management practices, organizations can expect to achieve higher performance outcomes. In addition a comparison between Slovenian and Polish data subset was performed. The results revealed some distinct elements, namely regarding the performance outcome. For example, the results indicate that Slovenian organizations achieved higher scores in business, environmental and operational performance, while Polish organizations achieved higher scores in social performance.

High-speed rail and air passenger transport : a comparison of the operational environmental performance
Milan Janić, 2003, original scientific article

Abstract: This paper presents an overview of the environmental performance of high-speedrail (HSR) and air passenger transport (APT) in the European Union (EU). This performance embraces the direct environmental burdens/emissions such as energy consumption, air pollution, noise, landtake and land use, safety and congestion. A comparison of the marginal values of particular burdens/emissions and their costs (externalities) is carried out. The results have shown that significant mitigation of the impacts and savings of costs could be achieved by substitution of air passenger transport by high-speed rail. The substitution can be carried out through competition and complementarity of operations of both modes.
Keywords: high-speed rail, air passenger transport, interactions, environmental performance, burdens, emmisions, externalities
