  • Group Decision Making Model for Evolution and Benchmarking Explosive
           Ordnance Risk Education (EORE) Messages in Iraq Based on Distance
           Measurement and Spherical Fuzzy Set

    • Authors: Hadeel M. Al Shukri; Abdelaziz Dammak
      Abstract: Explosive Ordnance Risk Education Messages (EORE) is a multi-criteria decision-making problem (MCDM) based on three steps, namely, the identification of distinct evolution criteria, the significance criteria, and the variation of data. Because it makes use of a more sophisticated classification technique, the group decision method (GDM) based on weighted arithmetic mean (AM) to prioritize (EORE) messages is the proper approach. In contrast to GDM, which explicitly weights each criterion, GDM implicitly weights each alternative's criterion values. With the help of the new hybrid method weighting technique, we can overcome this theoretical difficulty by providing explicit weights for criteria generated with zero inconsistencies and combined with the new distance-based weighting method. SFS (spherical fuzzy set) is used in hybrid methods, although it can only be used to solve the ambiguity associated with the theoretical concerns outlined above.

  • The Historical Background of a Famous Indeterminate Problem and Some
           Teaching Perspectives

    • Authors: Ioannis Rizos; Nikolaos Gkrekas
      Abstract: The well-known from the History of Mathematics “hundred fowls problem” is the topic of this paper. Our main aim is to analyze the historical background of the problem and to present some ways of solving it, which have different characteristics, and each one represents a particular strategy. The interaction of Eastern and Western mathematics and the combination of different fields like Algebra and Technology in order to solve the problem has been highlighted. The study of the specific topic revealed some teaching perspectives, which we note at the end together with some concluding remarks. This paper might have implications in future research in the field of indeterminate analysis but also in Mathematics Education.
