Investment plan and evaluation of the transition of a farm to a wellness tourist farm
Tatjana Klakočar, Karmen Pažek, Lazar Pavić, 2023, izvirni znanstveni članek

Opis: This study aimed to develop a commercial concept for transforming farms into wellness tourist destinations. The proposed scenario involved the renovation of a hayrack into a highend tourist accommodation, comprising relaxation rooms with panoramic glass walls and the renovation of the barns, as well as an outdoor swimming pond. The research methods included description, compilation, and synthesis to explore the legislation in Slovenia related to investment performance and trends in wellness tourism to support the realisation of the proposed investment. Furthermore, the study used the method of financial estimation of investment using cost-benefit analysis to facilitate the transition. Four datasets were used for the estimation: investment income, investment costs, end value of the investment, and annual interest rate. The estimated investment cost was €530,000 and the total estimated revenue was €192,720, with total costs amounting to 50% of the total income, as well as an annual cash flow of €96,360, which was used in the assessment of the investment return period. According to the findings, the investment return period is 15 years with the lowest annual cash flow and interest rate of 3.5%. However, caution is advised due to uncertainties in the long-term costs of raw materials and energy.

ECONOMIC EFFICIENCY ANALYSIS OF DIVERSIFICATION IN MILK FARM BUSINESS USING REAL OPTIONS APPROACH
Nemanja Jalić, 2025, doktorska disertacija

Opis: The significance of the agricultural sector in the economy of Republika Srpska, as well as the importance of dairy cattle farming within agriculture, determined the thematic field of the research, which had several key research objectives. The first objective of the dissertation was to determine the economic efficiency of the investment in milk production and sales on family farms with 8-15 dairy cows in Republika Srpska. The second objective was to assess the risk, or volatility, of such investment projects. The third objective was to calculate the additional value of diversification in transitioning from selling milk to milk processing into cheese on the same farm and determine the additional project's strategic value. The final objective was to compare the case studies of the analyzed farms based on selected indicators. Primary data were collected by interviewing five farmers who produce milk and process it into cheese while secondary data were obtained from various sources. Key data processing methods included Cost-Benefit Analysis, Monte Carlo simulations, and Black-Scholes and Binomial methods for evaluating real options. Based on the results of the analysis of milk production projects on small farms in Republika Srpska, it was concluded that these projects are economically unsustainable due to their negative and insufficiently satisfactory indicators. Through Monte Carlo simulations, it was determined that changes in input and output prices have an impact on such projects. Diversification of milk production into cheese processing on small farms is economically efficient, as the option values of the additional project are satisfactory and the NPVS, representing the total value of the additional project, ranges from €28,000 to €143,000 for all five analyzed farms. Based on the farm analysis, the conclusion is that the farm with the highest number of dairy cows implements an extensive feeding method, and sells its products at a prominent tourist location in rural areas has the best indicators and represents the best business model for small milk farms in the territory of Republika Srpska.

Developing a framework for closed-loop supply chain and its impact on sustainability in the petrochemicals industry
Lobna Tag el Sheikh, Rebeka Kovačič Lukman, 2022, izvirni znanstveni članek

Opis: Companies rely on formulating, implementing, and monitoring strategies in social, environmental and economic aspects to ensure that they achieve their goals and keep abreast of developments related to sustainability requirements. Therefore, our study develops a system to integrate the closed-loop supply chain approach in the petrochemical sector. The research follows the quantitative-based approach by collecting data through a questionnaire directed to employees in the supply chain departments, including 230 questionnaires that were collected. Correlation and structural equation models (SEM) were used. This technique consists of multiple regression analysis and factor analysis and analyses the structural relationship between the underlying structures and the measured variables. The results indicated a significant relationship between the supply chains that have a loop from the following perspectives: economic motivations, customer awareness, environmental legislation, and sustainability. By increasing financial reasons, customer awareness and environmental legislation, sustainability will increase as they all move in the same direction. Therefore, the overall effect of a closed-loop supply chain is positive and significant.
Ključne besede: closed-loop supply chain, petrochemicals, cost effectivity, product stewardship, multiple regression analysis, factor analysis, sustainability

Economic viability of alternative bedding material in broiler chicken farming
Jernej Prišenk, Maksimiljan Brus, 2022, izvirni znanstveni članek

Opis: The aim of this paper is to assess the economic viability of two different bedding materials used in broiler chicken farming processes. The materials considered are wood shavings and slice-dedusted straw. The slice-dedusted straw is considered an alternative type of bedding material produced by a company from Slovenia. While the technological and economic assessment of this type of bedding material has already been researched in the case of horse breeding, it is something new in the case of broiler chicken farming. Data collection is structured from two trials. Trial one (T1) is also known as daily observations, and trial two (T2) involves obtaining input data at the end of the fattening period. During T1, daily observations are focused on collecting data from technical characteristics, and in T2, the percentage of death proportions and average increments are observed, calculated, and considered as economic input data. The cost calculation model is used for the calculation of several different technical-economic indicators, which denote the influence of different bedding materials no economic production viability. Favorable economic results were found for slice-dedusted straw, which shows that this kind of alternative bedding material could be the better option.

Cost-benefit analysis of frost protection methods
Matej Fike, Mateja Fekonja, Miha Smrekar, 2020, izvirni znanstveni članek

Opis: Agricultural losses due to frost are high in various parts of the world, and in Slovenia, frost damage has frequently occurred in recent decades. Multiple methods for preventing frost damage exist and have been researched more or less extensively. Despite this, frost prevention measures are relatively sparsely used in Slovenia. This article aimed to review and compare active frost prevention technology for a case study of a typical fruit farm in Slovenia, based on a cost-benefit analysis. Most of the active methods require either large capital investment or have a high annual cost. According to our analysis, burning wood, used in Slovenia to battle frost damage in orchards and vineyards, proved to be the most cost-effective method, which is probably why it remains in wide use.

The relationship between the intellectual capital disclosure and cost of debt capital : a case of Slovenian private audited organisations
Neca Stropnik, Bojana Korošec, Polona Tominc, 2017, izvirni znanstveni članek

Opis: The existing empirical research into the association between intellectual capital disclosures by organisations and the cost of debt is scarce or is based solely on the samples of the (large) listed organisations. Since agency issues between management/owners and lenders exist also in (large) private organisations whose financing is greatly dependent on loans and whose audited annual reports can be a source of additional information for external users, we performed an empirical research to find the answer to the question whether the level of intellectual capital disclosure (as a whole and of its sub-categories) of organisations is associated with the cost of their debt capital. Our study was performed on a sample of private Slovenian organisations with audited annual reports. The results of our research did not reveal that lenders would take into account intellectual capital disclosures by Slovenian private audited organisations as the information about the potential for their future cash flows when deciding on the cost of debt issued to these organisations.

Financial aspects of a seismic base isolation system for a steel high-rack structure
Vojko Kilar, Simon Petrovčič, Simon Šilih, David Koren, 2013, izvirni znanstveni članek

Opis: The paper deals with the effects and costs of implementing a base isolation system for the mitigation of the seismic risk of an existing steel rack structure. Different realistic distributions of the payload mass and occupancy levels, which form different plan asymmetric variants, have been analysed. The results obtained by the pushover analysis (N2 method) are presented as top floor envelopes and as plastic hinge damage patterns. In the presented cost study, the cost of the implementation of the proposed base isolation system is compared with the estimated costs of structural repairs to the damaged structural members of the superstructure, as well as with estimated expenses of the downtime period. The results have shown that base isolation is, in general, not economically feasible for lower ground motion intensities, whereas it could be of great benefit in the case of moderate and high intensities, especially if the downtime period is taken into account.
Ključne besede: rack structures, seismic behaviour, base isolation, cost efficiency, mass eccentricity, pushover analysis

Karmen Pažek, Črtomir Rozman, Ferhat Ćejvanović, Andreja Borec, Darja Majkovič, Vjekoslav Par, Jernej Turk, 2005, izvirni znanstveni članek

Opis: The fruit production in Bosnia and Herzegovina (BIH) is slowly returning to normality after Balkan wars. Due to favorable climatic and soil conditions it presents a clear business opportunity for family farms. The decision which fruit species/variety to grow is a complex decision and should be made on the basis of sound empirical analysis. This paper present a multi criteria model for planning and decision making methodology based on expert system DEX-i. In the first stage the technological and financial cost benefit analysis were conducted for each fruit production alternative. The results were further evaluated with expert system DEX-i considering all possible criteria influencing the fruit grower decision. In the case of a sample family farm the plum yielded with best multi criteria evaluation, followed by apple and pear, while sour cherry gave unsatifactory outcome.

Concept and design of electric car body
Marko Sovič, 2012, diplomsko delo

Opis: In this thesis, a concept multi-material body for an electric vehicle is presented. A selection criteria for materials is made with regard to component function, their traditional shape and the mode of load they have to carry. Initial component design is based on a vehicle reference model. Numerous component modifications are done in dependence on the chosen materials and their production processes. Special attention is payed to the electric vehicle's body structural changes that need to be performed due to the passenger and battery safety. A program for distance simulation is made and used to evaluate cost changes, on a whole vehicle scale, when performing mass-reduction in a vehicle body. It has been proven that it is justified to use light materials.
Ključne besede: body-in-white, electric vehicle, material selection, Catia V5, distance simulation, cost analysis.
