“…Using this logic, we are able to include a large number of relevant documents within this review that may have otherwise been missed, enabling a more comprehensive assessment of SBD. We refer to this set of documents as Group B from this point forward 1,66–122 . We provide the complete listing for all Group B documents in Table 2.…”

Increasing system complexity has provided the impetus to develop new and novel systems engineering methodologies. One of these methodologies is set‐based design (SBD), a concurrent design methodology well suited for complex systems subject to significant uncertainty. Since the 1990s, numerous private, public, and defense sector design programs have successfully implemented SBD. However, concerns regarding SBD's complexity, tendency toward qualitative methods, and lack of quantitative tools have limited its use. To address these issues, our research surveys 122 refereed journal articles and conference papers to assess SBD's state‐of‐practice and identify relevant research opportunities. To accomplish these tasks, we perform a structured literature review to identify and assess relevant and influential research. We found that SBD's state‐of‐practice relies heavily upon decision and tradespace analysis with increasing emphasis on uncertainty modeling and MBSE. We found that the majority of SBD research consists of quantitative methodologies focusing on component and small system applications. We also found that complex system applications used mostly qualitative methodologies. We identify SBD research opportunities for requirements development, MBSE, uncertainty modeling, multiresolution modeling, adversarial analysis, and program management. Finally, we recommend the development of a comprehensive SBD methodology and toolkit, suited for complex system design across all stages of the product development life cycle.

“…Decision-making is a structured approach used to guide decision-makers to determine the best solution among different conflicting decisions by considering various sets of criteria at the same time (Deng and Jiang, 2018). Therefore, strategic decision-making is complex, particularly when several tangible and intangible criteria are considered simultaneously to select the best alternative (Adetunji et al, 2018). MCDM is an important branch of the modern decision theory, industrial engineering, and management systems which has many applications in various sciences (Guo and Zhao, 2017).…”

“…In pairwise comparisons, each expert k determines which of the two criteria is more important and then assigns a linguistic value a ij to show the degree of the relative importance of a criterion over another. (2) In the above pairwise comparison matrix, if two criteria have the same importance, let ; the values of represent the relative importance of criterion i with respect to the criterion j, and the values of reflect the relative importance of criterion j as compared to criterion i.…”

Given the growing competition in domestic and international agricultural product markets, choosing a business strategy compatible with requirements of marketing resources can guide agro-food firms to maintain and enhance competitive advantages. However, this is not as simple as it seems because the decision-making criteria expressed in a fuzzy manner and the relationship between them can be hierarchical or network-based. Therefore, the main goal of this study was to select the most suitable business strategy and to prioritize marketing resources for one of the major agro-food firms in Iran. To ensure the robustness of the results, both fuzzy analytic hierarchy process (AHP) and fuzzy analytic network process (ANP) were applied to prioritize business strategies and marketing resources. The results of both methods revealed that the differentiation strategy had the highest priority in terms of the experts' viewpoints. The results also showed that managerial and customer relationship capabilities were the most important criteria in selecting the differentiation strategy. According to the findings of the study, for the successful implementation of the differentiation strategy, company managers are recommended to take the following three main elements into huge consideration: financial conditions, paying attention to customer's needs and requirements, and the introduction of new products and services.

“…The European Journal of Social Sciences published the study [12] also focusing on TOPSIS and WSA method applications in terms of the multi-criteria decision analysis of economic activity for the EU states and candidate countries assessed by these two techniques. In this view, the system managed through decision-making is analyzed in the research work [13], where the authors introduce expert-opinion criteria to the methodology of managing system obsolescence applying multi-criteria decisionmaking, specifically the TOPSIS method and Monte Carlo simulations are suggested as a background for the article. The particular case study conducted in their research work was elaborated with a participation of military and civilian experts.…”

The subject of this article is to model and streamline processes in the area of the transport-supply logistics in a specific enterprise. The topic of the manuscript was implemented in a particular enterprise with the residence in the city of České Budějovice (South Bohemia region). The aim of the article is to step by step analyze the current state of the supply logistics of the specific subject and propose appropriate measures contributing to optimize the entire process using selected techniques of the Operations Research. By applying the methods of multi-criteria decision analysis (such as Weighted Sum Approach and Technique for Order Preference by Similarity to Ideal Solution), the most attractive option is chosen; i.e. the optimal supplier for the implementation of the transport-supply process that will enhance the effectiveness of specific logistics activities in the operation being examined. The conclusion in detail discusses individual contributions in terms of the suggested ways of modeling and improving the current state with respect to supply processes in the selected enterprise.
