Fuzzy Techniques for Decision Making

This book contains the successful invited submissions [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21] to a Special Issue of Symmetry on the subject area of “Fuzzy Techniques for Decision Making”.

We invited contributions addressing novel techniques and tools for decision making (e.g., group or multi-criteria decision making), with notions that overcome the problem of finding the membership degree of each element in Zadeh’s original model. We could garner interesting articles in a variety of setups, as well as applications. As a result, this Special Issue includes some novel techniques and tools for decision making, such as:

• Instrumental tools for analysis like correlation coefficients [1,16] or similarity measures [4] and aggregation operators [2,21] in various settings.
• Novel contributions to methodologies, like discrete optimization with fuzzy constraints [3], COMET [5], or fuzzy bi-matrix games [7].
• New methodologies for hybrid models [12,15,18,20] inclusive of theoretical novelties [9].
• Applications to project delivery systems [6], maintenance performance in industry [8], group emergencies [10], pedestrians flows [11], valuation of assets [13], water pollution control [17], or aquaculture enterprise sustainability [19].
• A comparative study of some classes of soft rough sets [14].

Response to our call had the following statistics:

• Submissions (58);
• Publications (21);
• Rejections (37);
• Article types: Research Article (21);

Authors’ geographical distribution (published papers) is:

• China (11)
• Spain (4)
• Pakistan (2)
• Poland (1)
• Japan (1)
• Taiwan (1)
• Slovenia (1)

Published submissions are related to various settings like fuzzy soft sets, hesitant fuzzy sets, (fuzzy) soft rough sets, neutrosophic sets, as well as other hybrid models.

I found the edition and selections of papers for this book very inspiring and rewarding. I also thank the editorial staff and reviewers for their efforts and help during the process.
