    A New Methodology for Improving Service Quality Measurement: Delphi-FUCOM-SERVQUAL Model
    (MDPI, 2018) Prentkovskis, Olegas; Erceg, Živko; Stević, Željko; Tanackov, Ilija; Vasiljević, Marko; Gavranović, Mladen
    The daily requirements and needs imposed on the executors of logistics services imply the need for a higher level of quality. In this, the proper execution of all sustainability processes and activities plays an important role. In this paper, a new methodology for improving the measurement of the quality of the service consisting of three phases has been developed. The first phase is the application of the Delphi method to determine the quality dimension ranking. After that, in the second phase, using the FUCOM (full consistency method), we determined the weight coefficients of the quality dimensions. The third phase represents determining the level of quality using the SERVQUAL (service quality) model, or the difference between the established gaps. The new methodology considers the assessment of the quality dimensions of a large number of participants (customers), on the one hand, and experts’ assessments on the other hand. The methodology was verified through the research carried out in an express post company. After processing and analyzing the collected data, the Cronbach alpha coefficient for each dimension of the SERVQUAL model for determining the reliability of the response was calculated. To determine the validity of the results and the developed methodology, an extensive statistical analysis (ANOVA, Duncan, Signum, and chi square tests) was carried out. The integration of certain methods and models into the new methodology has demonstrated greater objectivity and more precise results in determining the level of quality of sustainability processes and activities.

    A New Model for Stock Management in Order to Rationalize Costs: ABC-FUCOM-Interval Rough CoCoSo Model
    (MDPI, 2019) Erceg, Živko; Starčević, Vitomir; Pamučar, Dragan; Mitrović, Goran; Stević, Željko; Žikić. Srđan
    Cost rationalization has become imperative in every economic system in order to create adequate foundations for its efficient and sustainable management. Competitiveness in the global market is extremely high and it is challenging to manage business and logistics systems, especially with regards to financial parameters. It is necessary to rationalize costs in all activities and processes. The presence of inventories is inevitability in every logistics system, and it tends to create adequate and symmetrical policies for their efficient and sustainable management. In order to be able to do this, it is necessary to determine which products represent the largest percentage share in the value of procurement, and which are the most represented quantitatively. For this purpose, ABC analysis, which classifies products into three categories, is applied taking into account different constraints. The aim of this paper is to form a new model that involves the integration of ABC analysis, the Full Consistency Method (FUCOM), and a novel Interval Rough Combined Compromise Solution (CoCoSo) for stock management in the storage system. A new IRN Dombi weighted geometric averaging (IRNDWGA) operator is developed to aggregate the initial decision matrix. After grouping the products into three categories A, B and C, it is necessary to identify appropriate suppliers for each category in order to rationalize procurement costs. Financial, logistical, and quality parameters are taken into account. The FUCOM method has been used to determine the significance of these parameters. A new Interval CoCoSo approach is developed to determine the optimal suppliers for each product group. The results obtained have been modeled throughout a multi-phase sensitivity analysis

    A Novel Approach for the Assessment of Logistics Performance Index of EU Countries
    (De Gruyter, 2024) Ju, Mali; Mirović, Ivan; Petrović, Vesna; Erceg, Živko; Stević, Željko
    The impact of logistics performance in the era of sustainable mobility on the overall economic development of a country is inevitable. It can even be said to represent an extremely important component in identifying economic conditions and provides the possibility of defining adequate strategies. In this article, the evaluation of the member countries of the European Union was carried out on the basis of the logistics performance index (LPI) according to the latest report of the World Bank (WB). A unique and original Multiple-Criteria Decision Making (MCDM) approach has been created, and it involves the application of four methods: Criteria Importance Through Intercriteria Correlation, Method based on the Removal Effects of Criteria, and Entropy and Fuzzy ROV (Range of Value). The weighting coefficients of six factors were obtained with the first three methods in crisp form, so they were converted into Triangular Fuzzy Number. The Fuzzy ROV method has been created for the first time in the literature and represents a great contribution from the methodological aspect. The results of the developed model and the applied steps show that there are certain differences in the rankings compared to the World Bank report, with a note that the best-ranked countries have maintained their positions. In addition, verification tests of the originally obtained results were created, with an emphasis on the importance of evaluation parameter values and their impact on the LPI ranking.

    INNOVATIVE APPROACH TO MEASURING THE IMPACT OF FDI ON SOME MACROECONOMIC INDICATORS IN B&H
    (Sciendo, 2018) Subotic, Slobodan; Erceg, Živko
    The necessity of economic life and economic development of every economy is the free movement of capital. The international movement of capital has its balance of payment when capital export represents economic surplus in relation to consumption of the national economy and the import of capital represents an increase of consumption in regard to the output of a national economy. Analysis of the influence of foreign direct investment (FDI) on economic growth of the host country, among other things, is emphasized in the function of the achieved phase of its economic development. Taking all this into consideration, the aim of this paper refers to an attempt to indicate the significance and the role of FDI as well as the importance of attracting foreign direct investment in B&H and the determination of the effects of FDI on the economy of B&H. In this regard, we will try to determine the level of FDI’s impact on some macroeconomic indicators in B&H (GDP, import, export, unemployment) by using contemporary SPSS statistical analysis program (model) and applying the methods (calculating coefficients) of correlation and regression analysis. In other words, we will determine the analytical expression used to describe a statistical relationship of these macroeconomic categories.

    INTEGRATED MCDM MODE L FOR PROCESSES OPTIMIZATION IN THE SUPPLY CHAIN MANAGEM ENT IN THE WOOD COMPANY
    (2019) Erceg, Živko; Mularifović, Fatima
    Supply chain management (SCM) is a global strategy in nowadays business environment. It is a useful tool for managing a number of processes and activities on a daily basis in order to achieve a competitive advantage. Also, in order to achieve adequate bases for successful functioning, it is necessary to know their abilities and weaknesses; this knowledge, yet, requires decomposition of the overall system. In this paper the decomposition in a wood company and its supplier selection in the subsystem of procurement is performed. For determining criteria weights the Full Consistency Method (FUCOM) is applied while the ranking of suppliers is performed using the Weighted Aggregated Sum Product Assessment (WASPAS) method. The obtained results are checked through the sensitivity analysis that is formed with modeling of criteria weights. In the sensitivity analysis it was found that the changes in the significance of the criteria could influence the decision-making and ranking of suppliers.
