Razvoj sistema za podršku odlučivanju u procesu obuke vojnika
No full textОвај рад представља систем за подршку у одлучивању примењен при обуци младих војника и кадета током прве две године Војне академије, са акцентом на вештине гађања коришћењем DIDEX методологије. За потребе развоја система, праћени су кадети у Војној академији који су учествовали у обуци путем симулатора који омогућава ефикасније усвајање вештина гађања кроз реалистичне сценарије. Истраживање је показало да кадети који су учествовали у обуци путем симулатора, посебно они који су вежбали два пута недељно, имају значајно боље резултате у гађању у поређењу са контролном групом и онима који су вежбали једном недељно. Међутим, просторни капацитет ограничавају употребу симулатора те је неопходно проценити којем полазнику треба понудити обуку путем симулатора. Развијени систем за подршку одлучивању показују да комбинација симулација и циљаног саветовања има потенцијал да значајно побољша резултате у гађању. Такође, развијени систем за подршку одлучивању заснованог на DIDEX методологији пружа персонализоване препоруке за обуку, усмерене на појединачне потребе стрелаца
CAN E-PROCUREMENT BE A PANACEA FOR UPGRADING THE COMPETITION AND EFFICIENCY IN PUBLIC PROCUREMENT?
No full textThe aim of this paper is to analyze whether electronic public procurement (EPP) has a positive and statistically significant impact on the efficiency and economy of the public procurement process as well as on broader participation of micro, small and medium enterprises (MSMEs), both of which are recognized as strategic goals of a government. For this purpose, focusing on transparency, efficiency, centralization and bidder participation, we use a database of 65,394 public contracts awarded in the Republic of Slovenia in 2016-2020. Our research shows that there is a strong positive correlation between EPP on the one hand and: (1) higher transparency, expressed by a decreasing share of non-transparent procedures; (2) higher efficiency and economy indicated by the degree of centralization; and (3) broader participation of MSMEs on the other hand. Contrary to expectations, the introduction of the EPP did not increase the intensity of competition and the acceptance of framework agreements as an instrument of centralized and collaborative procurement

Challenges in defining the framework for ESG reporting
No full textESG has emerged as one of the most prominent trends impacting corporate governance,
management, and investment over the last twenty years. Despite its widespread use, there remains a
lack of clarity regarding its application in corporate practice and in defining the correct way companies
should approach meeting the need for nonfinancial reporting on the way they conduct their business.
As trillions of dollars pour into investment products labeled as ESG, and as companies and regulators
engage with ESG policies, the term has taken on various interpretations, causing inconsistencies in the
ways in which companies create their ESG reports.
This article firstly aims to achieve clarity in defining the ESG reporting framework that can be universally
used as a standard form of ESG reports. Secondly, it emphasizes the challenges corporate
representatives have in making these reports, and the various differences in the way they are
constructed. Finally, it offers a critical analysis of different ESG frameworks and gives guidelines on

THE IMPORTANCE OF FORMALIZED SELECTION OF BPI METHODOLOGY FOR BPM SUCCESS
No full textThe field of business process management (BPM) has witnessed substantial expansion in literature
in recent decades. While BPM plays a pivotal role in establishing sustainable competitive advantages, a
considerable number of BPM projects still encounter challenges and fail to achieve success. Important part of
BPM is selection of business process improvement methodology. The aim of this paper is to examine the
relationship between formalization the choice of business process improvement methodology and BPM
success. Data were collected from 91 Serbian companies. It was concluded that organizations that lack defined
criteria for selecting a BPI methodology tend to experience lower rates of success in BPM success compared
to those that employ an analytical approach. Formalizing the selection of a BPI methodology for BPM success
holds practical importance because it can boost efficiency, align endeavors with organizational goals,
standardize processes, minimize risks, and cultivate a culture of ongoing enhancemen
Clustering Consumer Profiles in Peer-To-Peer Travel Accommodation
No full textThe sharing economy has significantly transformed the tourism landscape, introducing peer-to-peer accommodation platforms that have reshaped market dynamics and consumer behaviors. This study analyzes the socio-economic impact of these platforms on tourism. Employing a dataset from a survey of 344 respondents, we conducted a cluster analysis to identify distinct user profiles and their preferences. The analysis reveals two primary user clusters: 'Experienced Sharers' and 'Guided Novices', differentiated by their familiarity with and usage of sharing platforms. Key factors influencing user choices include personal experience, knowledge of shared accommodations, and socio-economic indicators such as city size and monthly income. Our findings underscore the dual impact of peer-to-peer accommodation: while it offers economic opportunities and diverse choices for consumers, it also presents challenges in terms of privacy concerns and the quality of service
