Artificial intelligence and agility-based model for successful project implementation and company competitiveness
Polona Tominc, Dijana Oreški, Maja Rožman, 2023, izvirni znanstveni članek

Opis: The purpose of the paper is to present a model of factors affecting the successful project implementation by introducing agility and artificial intelligence to increase the company’s competitiveness. In the model, the multidimensional constructs describing the implementation of an agile work environment and artificial intelligence technologies and tools were developed. These multidimensional constructs are agile work environment, agile leadership, agile team skills and capabilities, improving the work of the leader in the project, adopting AI technologies in the project, and using AI solutions in a project. Their impact on successful project implementation and on the company competitiveness was tested. The fundamental reason for conducting this research and developing the model is to enhance the understanding of factors that contribute to the successful implementation of projects and to increase a company’s competitiveness. Our developed model encompasses multidimensional constructs that describe the agile work environment and the utilization of AI technologies. By examining the impact of these constructs on both successful project implementation and company competitiveness, we aimed to establish a comprehensive framework that captures the relationship between agility, AI, and successful project implementation. This model serves as a valuable tool for companies seeking to improve their project implementation processes and gain a competitive edge in the market. The research was based on a sample of 473 managers/owners in medium-sized and large companies. Structural equation modeling was used to test the hypotheses. In today’s turbulent environment, the results will help develop guidelines for a successful combination of agile business practices and artificial intelligence to achieve successful project implementation, increasing a company’s competitiveness.

Active BIM system for optimized multi-project ready-mix-concrete delivery
Hana Begić, Mario Galić, Uroš Klanšek, 2023, izvirni znanstveni članek

Opis: Purpose – Ready-mix concrete delivery problem (RMCDP), a specific version of the vehicle routing problem (VRP), is a relevant supply-chain engineering task for construction management with various formulations and solving methods. This problem can range from a simple scenario involving one source, one material and one destination to a more challenging and complex case involving multiple sources, multiple materials and multiple destinations. This paper presents an Internet of Things (IoT)-supported active building information modeling (BIM) system for optimized multi-project ready-mix concrete (RMC) delivery. Design/methodology/approach – The presented system is BIM-based, IoT supported, dynamic and automatic input/output exchange to provide an optimal delivery program for multi-project ready-mix-concrete problem. The input parameters are extracted as real-time map-supported IoT data and transferred to the system via an application programming interface (API) into a mixed-integer linear programming (MILP) optimization model developed to perform the optimization. The obtained optimization results are further integrated into BIM by conventional project management tools. To demonstrate the features of the suggested system, an RMCDP example was applied to solve that included four building sites, seven eligible concrete plants and three necessary RMC mixtures. Findings – The system provides the optimum delivery schedule for multiple RMCs to multiple construction sites, as well as the optimum RMC quantities to be delivered, the quantities from each concrete plant that must be supplied, the best delivery routes, the optimum execution times for each construction site, and the total minimal costs, while also assuring the dynamic transfer of the optimized results back into the portfolio of multiple BIM projects. The system can generate as many solutions as needed by updating the real-time input parameters in terms of change of the routes, unit prices and availability of concrete plants. Originality/value – The suggested system allows dynamic adjustments during the optimization process, andis adaptable to changes in input data also considering the real-time input data. The system is based on spreadsheets, which are widely used and common tool that most stakeholders already utilize daily, while also providing the possibility to apply a more specialized tool. Based on this, the RMCDP can be solved using both conventional and advanced optimization software, enabling the system to handle even large-scale tasks as necessary.

Ephemerality in personal memory travel : encountering the changing environment
Andreja Trdina, Maruša Pušnik, 2023, izvirni znanstveni članek

Opis: This article approaches personal memory travels with the aim of investigating people’s encounters with the changing environment in relation to time. It centers on the intra-actions with perceptual ephemera as immaterial non-solid entities to argue that our relational reality is a cyclical, dis-continuous process of past and present encounters. The study is grounded in the post-humanist performativ-ity approach and based on personal life histories of memory trips gathered in Slovenia with the help of in-depth interviews and photo-elicitation. Findings suggest that travelers’ engagements with ephemera at site illustrate complex entanglements between human and other (immaterial) entities as co-constituted in time and from within time, provoking the production of situated and temporally sensitive knowledge about the more-than-human world. The article endorses the significance of memory work and human engagements with absences and resonances, both allusions to other (past) contexts, as fundamental for cultivating post-anthropocentric attitudes and advancing the habit of timefulness.

Urban greening as a cooling tool towards the heat island effect
Anja Bubik, Lucija Kolar, 2019, izvirni znanstveni članek

Opis: Roofs, as the top layer of the urban environment, significantly contribute to overheating and creating a heat island, which is known as one of the most critical global warming effects. There are several ways to mitigate the effects of such heat islands, among which greening is the most natural, sustainable solution, and also economically acceptable and socially valued principle. Vegetation is known to significantly improve the urban microclimate and directly reduce the effect of the urban thermal core. At the Environmental Protection College in collaboration with the Institute Complementarium, both based in Slovenia, we conducted a pilot experiment to evaluate greening, in our case the principle of a flat green roof, as an effective and promising approach for reducing an urban heat island and its effects. Temperature measurements have shown that the green surface can lower both the surface temperature itself (e.g., the roof) and the air surrounding the green surface. We have presented an initial pilot case, which is planned to be upgraded in the future to confirm our current results and assumptions. In addition, we summarized data showing that Velenje is, in view of annual higher average temperatures, a highly suitable urban environment for the introduction of greening principles on the top urban layers.

A conceptual model of developing an agile work environment
Katja Crnogaj, Polona Tominc, Maja Rožman, 2022, izvirni znanstveni članek

Opis: This study has highlighted the need for an agile work environment to enhance companies’ performance, growth, and sustainability. In today’s rapidly changing business world, the goal of every individual and team in a company should be to deliver value to customers. The paper highlights theoretical and empirical evidence on the importance of an agile work environment and its positive effect on company performance. In addition, the paper provides insights into the important concept of developing an agile work environment and offers a conceptual model with five selected constructs, which can be leveraged to build an agile mindset in companies. Moving away from traditional leadership models, this paper highlights the significant role that agile leadership can play in enhancing effectiveness and performance, even in long-established large companies. The empirical research was based on 468 randomly selected medium and large Slovenian companies. Structural equation modelling (SEM) was used to test the model. The empirical results show that changing and adaptive agile companies are the ones that thrive more easily in an environment that is unpredictable and characterized by rapid change.

Country life in the digital era : comparison of technology use and cybercrime victimization between residents of rural and urban environments in Slovenia
Igor Bernik, Kaja Prislan Mihelič, Anže Mihelič, 2022, izvirni znanstveni članek

Opis: Cybercrime is one of the most significant security challenges of the 21st century. However, official statistics do not provide insights into its prevalence and nature. Representative cross-sectional field studies may help fill this gap, focusing on differences between urban and rural technology users. We (a) investigated the association between the purpose of computers and other electronic device usage and perceived vulnerability, (b) compared the differences in the purpose of computers or other electronic device use and perceived vulnerability, and (c) compared the perceived cyber victimization between residents of rural and urban areas. We conducted a field study that resulted in a representative sample of the Republic of Slovenia in Europe. We found several significant differences in the purpose of technology use and perceived cyber victimization. Furthermore, the results indicate that the purpose of technology use is somehow associated with perceived vulnerability in cyberspace; however, such associations are different in cyberspace than in the material world.
