Multi-objective optimization algorithms with the island metaheuristic for effective project management problem solving
Christina Brester, Ivan Ryzhikov, Eugene Semenkin, 2017, izvirni znanstveni članek

Opis: Background and Purpose: In every organization, project management raises many different decision-making problems, a large proportion of which can be efficiently solved using specific decision-making support systems. Yet such kinds of problems are always a challenge since there is no time-efficient or computationally efficient algorithm to solve them as a result of their complexity. In this study, we consider the problem of optimal financial investment. In our solution, we take into account the following organizational resource and project characteristics: profits, costs and risks. Design/Methodology/Approach: The decision-making problem is reduced to a multi-criteria 0-1 knapsack problem. This implies that we need to find a non-dominated set of alternative solutions, which are a trade-off between maximizing incomes and minimizing risks. At the same time, alternatives must satisfy constraints. This leads to a constrained two-criterion optimization problem in the Boolean space. To cope with the peculiarities and high complexity of the problem, evolution-based algorithms with an island meta-heuristic are applied as an alternative to conventional techniques. Results: The problem in hand was reduced to a two-criterion unconstrained extreme problem and solved with different evolution-based multi-objective optimization heuristics. Next, we applied a proposed meta-heuristic combining the particular algorithms and causing their interaction in a cooperative and collaborative way. The obtained results showed that the island heuristic outperformed the original ones based on the values of a specific metric, thus showing the representativeness of Pareto front approximations. Having more representative approximations, decision-makers have more alternative project portfolios corresponding to different risk and profit estimations. Since these criteria are conflicting, when choosing an alternative with an estimated high profit, decision-makers follow a strategy with an estimated high risk and vice versa. Conclusion: In the present paper, the project portfolio decision-making problem was reduced to a 0-1 knapsack constrained multi-objective optimization problem. The algorithm investigation confirms that the use of the island meta-heuristic significantly improves the performance of genetic algorithms, thereby providing an efficient tool for Financial Responsibility Centres Management.

Providing the success of Six Sigma by proper project identification and selection
Dušan Gošnik, Andrej Bertoncelj, 2010, izvirni znanstveni članek

Opis: Results of Six Sigma projects are related to company performance. Successful Six Sigma projects increase customer satisfaction and have many other positive effects on organisations. Success of Six Sigma projects is related to key management decision about how to identify potential projects and which projects to select for final implementation. This research is oriented toward the study of tools used in the phase of Six Sigma project identification and criteria used in the phase of Six Sigma project selection. The purpose of this research is to compare results from manufacturing sector in Slovenia and the UK. Results of this study indicate that management within the organisations tend to identify potential Six Sigma projects with the use of different tools, such as: brainstorming (Slovenia and UK.), followed by Critical To Quality tree (UK.), and interviews and customer visits (Slovenia). Further, the results show that the final decision about Six Sigma projects selection in the UK and Slovenia include different criteria, such as: customer benefit (Slovenia and UK), finance impact (UK) and connection to business strategy (Slovenia). Many companies in the UK as well in Slovenia combine the use of tools and balanced selection criteria at the same time.

Survey of accomplishments in BIM implementation in Croatia, the Czech Republic, Germany, and Slovenia
Mario Galić, Vaclav Venkrbec, Franziska Chmelik, Immo Feine, Zoran Pučko, Uroš Klanšek, 2017, izvirni znanstveni članek

Opis: Building information modelling (BIM) may currently be considered the fastest developing concept in the field of construction management, aiming to become a global standard. Although the roots of the concept date back to the mid-1970s, some original expectations are still missing from its implementation. There has been a time gap between its theoretical and practical implementations. While the simultaneous development of information technologies is one reason for the implementation delay, other reasons remain unclear. This paper analyzes the gaps between theoretical and practical BIM application, as well as the legislation regarding BIM implementation in four countries (in alphabetical order: Croatia, the Czech Republic, Germany, and Slovenia). The paper additionally presents a survey of current practical BIM applications as well as general and theoretical feedback from construction projects that implemented BIM.

Developing soft skills for engineering
Franc Gider, Tanja Urbančič, 2010, izvirni znanstveni članek

Opis: While advanced technologies are entering schools at all levels, we claim that other skills required to deal with them in the complex modern world should not be neglected in the education system. In this article, a promising approach to interdisciplinary postgraduate education is described. The idea of the »Team project« course is to give the students the opportunity to gain experience in an extensive project where various skills are needed, e.g. teamwork, coordinating work, project management, research, problem solving, public presentations, time management, etc. The course is obligatory and held in the first year of the master study program at the School of Engineering and Management of the University of Nova Gorica. The main advantage of the course is to give the students hands-on experience of work on a project that is very close to reality. Students are forced to gain experience in teamwork and to overcome the uncertainties and obstacles that arise in such projects. Since the launch of the course, several improvements have been made with the aim of improving the performance of the course. Nevertheless, the course remains a challenge for both students and teachers.

Usage of agile SCRUM methodology on configuration management application
Željko Stanojević, 2017, magistrsko delo/naloga

Opis: The purpose of the master thesis is to research and determine how to successfully manage a project using agile methodology Scrum. Scrum methodology will be used to improve the functionality of existing internally developed software solutions. Scrum, being an agile methodology, is an alternative approach to the traditional waterfall methodology, and is typically used in software development. Agile methodologies help teams respond to a project’s unpredictability by using incremental, iterative way of work known as sprints. The first part of the master’s thesis presents a problem, defines goals and methods used, and the necessary tools required to achieve the objectives. The following part of the thesis presents the foundations of agile methodologies and describes the used methodology – Scrum - in detail. In the practical part, the thesis presents the existing software solution and opportunities for its improvement. We use Scrum for upgrading existing application, including all the attributes of the mentioned methodology, from team design to artifacts and events. The thesis also presents a renewed application in detail. In conclusion, by using the SWOT analysis we observe suitability for use of the Scrum methodology in the case of renewal of application and propose further changes to improve the application.

Impacts of the implementation of a project management information system
Mirjana Kljajić Borštnar, Andreja Pucihar, 2014, izvirni znanstveni članek

Opis: Background: The problems of resources management (human, financial, time) in multi-project companies are inherently complex and need to be addressed systematically, in both small and large organizations. Furthermore, there is a need for transparent communication and collaboration within the organization as well as with partnering organizations. There are many methodologies and tools supporting project management, which are themselves complex and are therefore not widely adopted, especially among small companies. Objectives: The aim of this paper is to analyse impact of the implementation of a flexible cloud-based project management information system (PMIS) from the human resources, financial management, and collaboration points of view. Method: We have conducted a case study in a small Slovenian research and development company, that has implemented the 4PM PMIS. Results: The findings imply the importance of keeping the balance of the creative processes that are unstructured, rule free and even chaotic, with structured processes monitor and control. Conclusions: The results of the study suggest that the use of “4PM” in support of multi-project management improves human resources and financial management in a collaborative and transparent way when implemented in an open and highly motivated environment

Cost optimal project scheduling
Uroš Klanšek, Mirko Pšunder, 2008, izvirni znanstveni članek

Opis: This paper presents the cost optimal project scheduling. The optimization was performed by the nonlinear programming approach, NLP The nonlinear total project cost objective function is subjected to the rigorous system of the activity preceden- ce relationship constraints, the activity duration constraints and the project duration constraints. The set of activity precedence relationship constraints was defined to comprise Finish-to-Start, Start-to-Start, Start-to-Finish and Finish-to-Finish precedence relationships between activities. The activity duration constraints determine relationships between minimum, maximum and possible duration of the project activities. The project duration constraints define the maximum feasible project duration. A numerical example is presented at the end of the paper in order to present the applicability of the proposed approach.

Tadeja Leskovar, 2014, magistrsko delo

Opis: This Master’s thesis topic are Enterprise Resource Planning (ERP) solutions in general with emphasis on systems appropriate for small and medium sized enterprises and industry specific solutions. The chosen industry and case study of the present thesis are manufacturing and construction; specifically the industry of ready-mixed concrete manufacturing. An ERP is a company-wide system that replaces many previously scattered and standalone systems of individual departments and offices. After the (successful) implementation it integrates all functions into a single, automated system that runs on a single database. This thesis strives to present different stages of ERP acquiring, from decision-making, through implementation and use. Because the empirical part contains a presentation of an actual business and their requirements, we focus in the particular conditions and issues related to the size and industry of the given company, Beton – Betonski izdelki Kuhar Dušan, s.p throughout the thesis. Additionally, part of the thesis is also presentation and potential beneficial role of one of the leading organizations in the area of project management – Project Management Institute. The outcome of our research is realization that ERP solutions are a crucial aspect of modern companies if they wish to be competitive on the market, have the ability to grow, and continuously maintain the existing pool of costumers. However, before the right ERP solution can be selected, a careful decision-making needs to be undertaken and implementation has to be thoroughly planned. There are many tools and guides that can be used with such demanding project. Project Management Institute, which will be presented in this work, offers many advices on the topic in question.
