We are very happy to introduce this inaugural issue of the Turkish Journal of Fuzzy Systems (TJFS): An official journal of Turkish Fuzzy Systems Association which is a member of International Fuzzy Systems Association (IFSA).
Uncertainty, ambiguity or in other words fuzziness is all around of our life. We believe that it is not wrong to say: “we are surrounded with fuzziness”. However, it is interesting to note that most of the classical computing and modeling approaches available for researchers and practitioners were developed based on the assumption of “everything is known with certainty”. This is fine but with a penalty of loosing lots of useful information for modeling and computing. In order to overcome this problem Prof. Dr. Lotfi A. Zadeh proposed “fuzzy logic” as an alternative approach. Since its introduction, fuzzy logic has found numerous applications in many diverse areas. Research related to fuzzy logic and its extensions is still an open and promising active research area. There is still a very long way to go and much to explore. It is now very well known by researchers and practitioners that fuzzy logic and systems provides a lot of tools and methodologies to model uncertainty and ambiguity which is an important characteristic of many real life systems. However, we should mention here that in most of the cases it is not straightforward to distinguish between problems that actually require a crisp or fuzzy approach in their modeling and solution. Actually, the boundary between them is also uncertain. What types of problems really require modeling and solution with fuzzy logic? What is “fuzziness” in them? This is actually the first basic question that needs to be answered before developing a useful fuzzy model and its solution methodology. The main goal of TJFS is to promote the publication of high quality papers which present the proper use and innovative applications of fuzzy logic and systems. TJFS will mainly focus on the determination of problems which can most suitably be handled through a fuzzy systems approach (i.e. fuzziness is their fundamental characteristics) and will provide a unique journal for publishing the recent research on applications, practices, and methodologies of fuzzy sets and systems. Therefore, TJFS requires from the prospective authors to clarify why their problem needs a fuzzy modeling and/or solution approach in their work in order to be considered for possible publication in TJFS.
TJFS favors engineering and application oriented papers. TJFS is a refereed, electronic and open access journal that acts as a forum and source of information in the field of fuzzy logic and systems. This will help researchers and practitioners working in the field of fuzzy logic and systems, to discuss the new, innovative and emerging ideas, concepts, approaches, methodologies, applications and tools and to publicize information.
The inaugural issue provides some of the selected papers, which were also presented orally and discussed at the “FUZZYSS’2009: 1st International Fuzzy Systems Symposium, 1-2 October 2009, Ankara, Turkey”. After the re-submission of the revised manuscripts and refereeing processes, four papers were finally considered for the publication in the inaugural issue of TJFS. The first paper in this inaugural issue studies influence of transitive closure complexity in FJP-based clustering algorithms. The second paper presents fuzzy parameterized fuzzy soft set theory and its applications. The third paper proposes a fuzzy approach to DC motor position control and the final paper critiques artificial and classical logic from the perspective of deterministic and fuzzy logic.
Finally we would like to thank to our Honorary Editor Prof. Dr. I Burhan Turksen who played one of the key roles for initiating this journal as well as Turkish Fuzzy Systems Association. We also thank to the editorial board members of TJFS and the referees for their objective evaluation of papers and for their timely and detailed reports which have improved the quality of the accepted papers significantly. We sincerely thank to the contributing authors for their valuable work.
