“…First, the compatibility of opinions expressed by the Lithuanian experts was calculated (see Table 4). The compatibility of opinions expressed by the experts is considered sufficient when the condition W > 0.6 is met (Šateikienė et al, 2015;Akhmetshin et al, 2019). According to Motienė et al (2017), only if this condition is met, the results of the research can be used for making further recommendations.…”

As more and more attention is paid to the formation of models of new service development, it is noticed that the compositions of a new model are usually based only on examples of previous models that were presented in the scientific literature. Although the practical application of the proposed models in any organizational condition is often verified by empirical studies, the revisions of the validity of model compositions are still quite fragmented. The lack of such research does not give the possibility for any further improvement of the model or elimination of the revealed shortcomings and it makes the proper preparation for testing the proposed model in a company complicated. In order to evaluate the suitability of the composition of the newly formed model of service development in the conditions of modern service companies, an empirical evaluation was performed by using the methods of abstraction, comparative analysis, synthesis, and expert survey. According to the results of the research, the suggestions for the improvement of the new service development model were made and guidelines for further research were formulated.

“…Satir 35 utilized the fuzzy AHP technique to select the best BWT system. Šateikienė et al 36 employed PROMETHEE to evaluate and compare different BWT systems and their related technical parameters for ships in which BWT solutions were not anticipated during design. Karahalios 37 applied the hybrid multi-criteria decision-making method (AHP-TOPSIS) to help ship operators select the suitable BWT technology.…”

Giving the ratification of the ballast water management convention, a number of ballast water treatment technologies are emerging in the maritime industry; however, choosing the most appropriate technology has been a big challenge for ship owners because it is a very complex and critical task. The aim of this article is to propose a multi-attribute decision analysis model which integrates the fuzzy analytical hierarchy process and the weighted linear combination method into a more comprehensive approach to select the most appropriate ballast water treatment technology for ship owners. The proposed model consists of 6 attributes (i.e. technological readiness, commercial readiness, operational readiness, seafarer’s skills readiness, biological efficacy readiness and cost of ballast water treatment technologies) and 17 ballast water treatment technologies among which ship owners can choose the best. The fuzzy analytical hierarchy process is used to obtain more realistic weights of the attributes, while the weighted linear combination is applied to prioritize the technologies. To demonstrate the applicability of the model, it is applied to select the best ballast water treatment technology for a ship owner in Ghana. The result shows that the ballast water treatment technology which uses membrane filter is selected as the best. Sensitivity analysis is then carried out to determine the effect of changing attributes’ weights on the final priority rankings of the ballast water treatment technologies. Finally, the model is validated by comparing the obtained results to those from the PROMETHEE model and both results are consistent.

“…Considering the above challenges, transportation system is one of the implicational areas of MADM (Bagočius et al 2014;Elevli 2014;Šateikienė et al 2015). An MADM problem can be defined as follow (Zimmerman 1987): Suppose that we have a nonempty and finite set of decision alternatives, that their desirability will be judged according to a finite set of goals, attributes or criteria.…”

Fuzzy Belief Structure Based Vikor Method: An Application for Ranking Delay Causes of Tehran Metro System by Fmea Criteria

et al. 2016

Public transport is a critical part of civilization in this decade. The amount of money invested and the criticality of transferring people in an acceptable time and without any conflict made it a challenging problem for managers, especially in metropolises. Absolutely, making effective decisions in this area requires considering different aspects. Waiting time is a key criterion in apprising quality of public transport. In this paper, a real world case study of ranking causes of delay in Tehran (Iran) metro system is solved by developing multi attribute group decision-making VIšeKriterijumska Optimizacija I KOmpromisno Rešenje (in Serbian, VIKOR) method under uncertainty, where this uncertainty is captured by Fuzzy Belief Structures (FBS). The obtained results are then compared with a previously proposed Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method with FBSs. The results show that human related issues, along with the problems related to line and transportation system are the most important causes of delay. The obtained results of the problem seem acceptable for decision makers.
