Korporativno produktivno vzdrževanje tehničnih naprav
Edvard Krieger, 2021, master's thesis

Abstract: V magistrski nalogi predstavljamo korporativno produktivno vzdrževanje (KPV) tehničnih naprav, ki je zasnovano na osnovi integracije pozitivnih lastnosti do sedaj nam znanih postopkov vzdrževanja. Osnova je metoda Celovitega produktivnega vzdrževanja (Total Productive Maintenance – TPM), ki je bila v prejšnjem stoletju zasnovana na Japonskem. Nekatere stebre te metode smo spremenili (nadgradili) na osnovi naših izkušenj, ki smo jih z leti pridobivali na področju vzdrževanja tehničnih naprav. Kot primer v nalogi predlagamo implementacijo KPV na področju vzdrževanja avtomatskih zunanjih defibrilatorjev (Automated External Defibrillator – AED) na osnovi naših praktičnih izkušenj in podajamo prednosti takega vzdrževanja.
Keywords: vzdrževanje, Total Productive Maintenance, korporativno produktivno vzdrževanje, geostrateško položaj, defibrilator

Creation of own reserves for own shares in the acquisition of own shares for withdrawal by simplified procedure under Slovenian law where the consideration is paid in instalments
Gregor Drnovšek, 2018, original scientific article

Abstract: During the process of withdrawing own shares, the rules that are relevant, among others, to their acquisition by the company are regulations governing the creation of reserves for own shares. The regulations are clear in cases where the company acquires their own shares simultaneously with the payment of the purchase price. This article will pertain to the proper application of these regulations according to Slovenian law, specifically in cases where the company pays the purchase price for their own shares, which it intends to withdraw after acquisition, in instalments, and acquires their own shares only after paying the last instalment of the purchase price.
Keywords: reserves for own shares, protection of creditors, purchase price paid in instalments, capital maintenance principle, withdrawal of own shares, joint-stock company, balance sheet law

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.

Weibull decision support systems in maintenance
Khalid Aboura, Johnson Agbinya, Ali Eskandarian, 2014, original scientific article

Abstract: Background: The Weibull distribution is one of the most important lifetime distributions in applied statistics. Weibull analysis is the leading method in the world for fitting and analyzing lifetime data. We discuss one of the earliest decision support system for the assessment of a distribution for the parameters of the Weibull reliability model using expert information. We then present a different approach to assess the parameters distribution. Objectives: The studies mentioned in this paper aimed to construct a distribution of the parameters of the Weibull reliability model and apply it in the domain of Maintenance Optimization. Method: The parameters of the Weibull reliability model are considered random variables and a distribution for the parameters is assessed using informed judgment in the form of reliability estimates from vendor information, engineering knowledge or experience in the field. Results: The results are the development of modern maintenance optimization models that can be embodied in decision support systems. Conclusion: While the information management part is important in the building of maintenance optimization decision systems, the accuracy of the mathematical and statistical algorithms determines the level of success of the maintenance solution.
Keywords: Weibull distribution, reliability, inference, maintenance, expert opinion

Estimating marginal infrastructure cost in new infrastructure charging model
Marjan Sternad, Timotej Jagrič, Bojan Rosi, 2017, original scientific article

Abstract: Competitiveness of rail transport compared to road transport has been reducing, especially on regional railway lines. To improve this situation, the EU adopted various directives and regulations to increase efficiency of railway undertakings. In this paper we present an organizational and economic model based on European policies for local railway system. The organizational model is based on multi-criteria decision analysis. For the economic model we used an econometric approach to estimate the cost function and marginal costs in regional lines, which constitute the basis for railway charges. By implementing such an organizational model, the functioning of the railway network will improve. The research found that a change in the existing model of calculating costs of infrastructure use would bring economic effects for the railway infrastructure manager and the providers of transport. Using the proposed model we also found that it is reasonable to increase the flow of goods on unused regional railway lines because the railway infrastructure maintenance costs are inelastic with regard to transported gross tons.

Contingency factors influencing implementation of physical asset management practices
Damjan Maletič, Matjaž Maletič, Basim Al-Najjar, Katerina Gotzamani, Maria Gianni, Kalinowski, Boštjan Gomišček, 2017, original scientific article

Abstract: Purpose: The purpose of this empirical study is to examine the role of two contingency factors, i.e. uncertainty and competitiveness in relation to physical asset management (PAM) practices as well as to maintenance key performance indicators. The research is based on a premise that PAM, which was defined by risk management practices, performance assessment practices, life cycle management practices, and policy & strategy practices, has become an indispensable element of strategic thinking of asset owners as well as maintenance and asset managers. The purpose of this study is to advance the understanding of how organizations that face high or low level of uncertainty and competitiveness respond in terms of PAM deployment. Methodology/Approach: This study employed a data set based on a large-scale survey among organizations in six European countries (i.e. Slovenia, Poland, Greece, Sweden, Turkey and Slovakia). Data were collected from 138 organizations located in the above-mentioned countries to conduct the study. Findings: The results show that organizations that are faced with high level of uncertainty and competitiveness are more engaged in the deployment of PAM practices. Moreover, results show that when organizations are facing high levels of competitiveness they are using KPIs to a greater extent than organizations under low levels of competitiveness. Originality/value: From a theoretical perspective, this study contributes to the contingency theory by providing empirical evidence whether a context-dependent approach to PAM is needed. The findings also provide insights for managers on how to respond to the competitive pressure as well as how to customize PAM practices in order to adapt to the changes in dynamic organizational environment.

An application of analytic hierarchy process (AHP) and sensitivity analysis for maintenance policy selection
Damjan Maletič, Matjaž Maletič, Viktor Lovrenčič, Basim Al-Najjar, Boštjan Gomišček, 2014, original scientific article

Abstract: Purpose: The purpose of this paper is to apply an analytic hierarchy process (AHP) for the evaluation/selection of maintenance policy. Methodology/Approach: The paper adopts a case study approach of selecting most appropriate maintenance policy in the case of Slovenian paper mill company. Several steps of the AHP method are used in order to structure the decision-making process. Five possible alternatives are considered: failure based maintenance, preventive maintenance, total productive maintenance, reliability centered maintenance and total quality maintenance. Findings: This paper proposes a framework for maintenance policy selection based on the AHP methodology. The framework was applied to select the most appropriate maintenance policy in a paper mill company. The results suggest that total quality maintenance is the most suitable concept for a paper machine. By performing a sensitivity analysis, it was revealed that the final outcome remained stable in all cases when the weights of the main criteria were increased for 25 percent. Originality/value: The paper contributes to the literature by providing a framework for decision-making process regarding the maintenance policy selection. In addition, this paper utilizes an exponentially weighted moving average (EWMA) chart for performing a consistency test. Moreover, a sensitivity analysis also presents an important implication of this study.
