Management systems for handling these documents depend on specific demands of every organization an d the way the organization communicate with other business partners. Under specific demands we may consider availability of documents in their origina l or other appearances, time needed for the document retrieval, document handling costs and other criter ia that effect on the document management systems. The aim of lowering the costs of document handling organizations is implementing various document management systems, especially when documents are considered as working assets. Contemporary information and communication technologies enable "paperless" work, by implementing digital archiving systems that store documents temporarily or permanently. Before implementing such digital archiving systems it is necessary to develop the most suitable configuration which consists of available technical and ...

Discrete event simulation (DES) can help identify resource's bottlenecks, such as staffing, estimate process execution or delay times, test improvement suggestions in the process design phase, and overall assist in understanding how processes might impact performance in various scenarios. While many research papers report on the industry applications of BPM and DES, we focus to higher educational institutions (HEIS). Goals of the paper are: (1) to review the research of BPM and DES in HEIs, and (2) to discuss the impact of BPM and DES to process performance in one Croatian HEI. The case study methodology has been used in order to shed some light on the issue of applying discrete event simulation in BPM in the HEIs, especially for the purpose of collaboration improvement and impact assessment.

Organizations try to add or create new value for their customers by innovating existing or developing new business models and designing new products and/or services, implementing and using thereby new modern digital technologies. The selection of appropriate digital technologies, which are supposed to enable the desired business change, is addressing different challenges. Main reasons that make the decision hard are that not all technologies are suitable for every business change and that some technologies are emerging and bring great impact on improvement in some industries, while the same technology in another industry can be widely in use or presents already a standard. This paper is aimed to give guidance on how to select one or combination of several appropriate technologies for steering the digital...

The proposed new approach is a Graphical Model Comparison Algorithm (GMCA) which includes a procedure, methods and an algorithm that can be used for comparing two data models for similarities. The comparison is based on the structural similarity of graphs representing data models that contain some semantically similar data objects.

That is the case for the agriculture field as well. Among many possibilities and different ICT solutions in agriculture, selection of the appropriate solution that will result in the satisfaction of both - customers and producers - becomes an important issue, and it is the main research topic of this paper. In this paper, we present the factors that influence the digital platform selection and propose two models for decision making on digital platforms. Decision models can help customers and producers to decide if a specific platform can be useful for their business. The decision model is based on a multi-criteria decision-making method called Dex. Dex is selected because it is very intuitive and less complicated than other multicriteria methods. On the other hand, Dex can aggregate all crucial factors and include the specifics and subjectivity (perception) of each user (customer or producer). The paper also contains a demonstration of the implementations of two models on the hypothetical cases. In future research, we plan to evaluate the model in practice (and possibly update it if needed) and present it to the scientific and professional community. That can help producers/customers to optimize their business processes but also give directions for the development of new platform functionalities for platform developers.

Nevertheless, the most severely affected was and still is the economic sector of countries across the world. One of the major pillars of global economies is the agricultural sector due to its significance in ensuring continuity in food supply and at the same time developing operating business models oriented on sustainability. For achieving these purposes, operating business models had to undergo serious reinventions often supported by digital technologies. In this paper, the impact of COVID-19 on the operating dimensions in agriculture is investigated to gather insights on digital technology implementations, as reported in scientific publications regarding agriculture and its sub-sectors. This research aims to create a conceptual and theoretical framework for investigating the influence of COVID-19 pandemic and technology-related changes that had to be done in the agricultural sector due to its impact.

The next question that becomes a focus of our interest is related to the prioritization of those factors. The first results suggest that some factors have a higher impact on producers (or customers) than others when deciding on digital platform selection in agriculture. In this paper, we will present several approaches that can be used to prioritize factors. Those methods are: direct assessment method, reciprocal ranks, SWING, pairwise comparison, analytical hierarchy process, analytical network process, and SNAP method. Some of those methods are simpler, and some are complex. In general, simpler methods are less, and the complex methods are more precise in terms of prioritization. On the other side, simpler methods are more understandable to the average customers (or producers) in terms of application than the complex methods. We analyzed all prioritizations methods and suggested the most appropriate method having a mind on the complexity of the method (understanding by users) and their precisions.

The reasons for this are, for sure, complexity and an extensive nature of BPMS. In this paper we describe our work on evaluation of the functionalities of BPMS aiming to define basic guidelines for BPMS selection. The research was based on case studies and gathering insights on consulting and customer experience by using semi-structured questionnaires. The goal of research activities within this broader project part was to systematize, analyze and evaluate the functionalities of business process management software and systems, in order to define guidelines for their selection, and further on to develop a guide that would be used by companies in selecting business process management software. In this paper we present one of the case studies dealing with BPMS from our research as well as key experience factors recognized in Croatia that influence later BPMS selection process.

According to existing literature, tourism-related industries suffered huge losses during and after national lockdowns and are struggling to transform their business operations for the post pandemic era. This research aims to contribute to reduce the knowledge gap on the impact of the COVID-19 pandemic on the tourism-related industries, especially when investigating its impact on business transformation. A qualitative literature review was performed in order to gather and analyze scientific publications reporting on business models and case studies in the context of tourism-related industries as well as to explore in-depth these articles in relation to drivers and technologies of transformation. Based on the results of the conducted research rethinking of business models encompasses building operations around social changes, consumers and organizational factors, while relying on innovative, mobile and social media related technologies. Resilience and sustainability confirmed to be important response mechanisms for business transformations in tourism-related industries.

The complex and comprehensive nature of BPM has resulted in the lack of a generally accepted framework for successful BPM adoption. One general means of ensuring BPM success is through the adoption of business process management software (BPMS). The fact that there is currently no consensus as to a generally accepted definition of BPM software makes it difficult to define the criteria for its selection. There are several reasons for this: (i) the size and complexity of the field, (ii) determining business needs is not always straightforward, and (iii) the BPM software market is complex and its features and capabilities vary greatly across vendors. In this article, we examine the contextual and technical perspectives of BPMS adoption and related critical success factors (CSF). The goal of this study was to propose BPMS selection guidelines with regard to the organizational, environmental and technological CSFs of BPMS adoption, to support decision makers in selecting the right BPMS. To accomplish this, we applied a multiple-case study approach and carried out a set of interviews in companies that have fully or partly adopted BPMS. Semi-structured interviews were used to gather quantitative data for those topics that can be evaluated numerically, and qualitative contextual (organizational and environmental) CSFs relevant for BPMS adoption success.

Simulation of business processes, as part of the process modelling and improvement activities in ... more Simulation of business processes, as part of the process modelling and improvement activities in Business process management (BPM) and Business process improvement/reengineering (BPI/BPR), plays a significant role in the assessment of the effects of contemporary information and communication technologies (ICT) and the optimization of resources. Contemporary business process management/modelling tools (BPM tools) embed simulation features as a part of process analysis and process optimization. Although these tools support simulation, there are challenges in their simulation capabilities that can limit or obstruct their use. The limiting capabilities that we are addressing in this paper deal with batch processing activities and dynamic aspects of the capacity changes over time in such activities. The paper explores thereby the dynamic aspects of the simulation, in activities with batch processing within the process model, as the possibilities of some popular business process modelling or management tools. As a supplementary solution, to overcome such limitations of contemporary BPM tools, their batch activity simulation capabilities were compared by running simulations based on Time driven activity based method model (TD ABC model). Also, significant limitations of contemporary BPM tools with process simulation features are assessed and discussed, as well as advantages and disadvantages in comparison to TD ABC model simulation.

Since most contemporary norms for process modelling rely on directed connectivity of objects in the model, connections between objects form sequences which can be translated into performing scenarios. Whereas sequences can be tested for completeness in performing process activities using simulation methods, the similarity or difference in static characteristics of sequences in different model variants are difficult to explore. The goal of the paper is to test the application of a method for comparison of graphical models by analyzing and comparing static characteristics of process models. Consequently, a metamodel for process models is developed followed by a comparison procedure conducted using a graphical model comparison algorithm.

In the development of such platforms, the scope, architecture, realization technology as well as the channels used are important. However, a well-accepted/designed platform does not guarantee profitable results in a digital business model. There are various soft factors that can significantly affect the reach of a platform. Due to its role in food distribution, the specific lifecycle of products and seasonality, agriculture is an industry where timely reach is crucial. In this paper, we investigate the factors influencing users’ perceptions toward platforms in agriculture. We consider both the perspective of the customers/buyers, and the perspective of the producers/sellers. We also examine the perception factors that can influence one’s intention to join and adopt digital platforms. The identification of relevant perception factors is based on a literature review and empirical data from publicly available sources. Our goal in future research is to confirm or revise factors that impact perception, and to assess the impact of perception on the design and functionality of digital platforms, as well as its impact on the development of digital business models.
