Special Issues of IJFS and JCIE – Submission Guidelines
To be considered for the special issue of either the International Journal of Fuzzy Systems (IJFS) or the Journal of the Chinese Institute of Engineers (JCIE), authors must first submit a Conference Proceedings-only paper prepared in accordance with the conference formatting guidelines via the conference submission system, selecting either a Regular Session or any Special Session, and complete the registration process. In addition, authors must submit a version formatted according to the respective journal's requirements directly to the corresponding Guest Editor.

Rejected papers will not be considered for inclusion in the corresponding special issue and will only be presented in the originally selected session.
-
Revised papers must be presented in a designated special session related to the respective journal (IJFS or JCIE) and will be subject to questions from the review committee.

1. International Journal of Fuzzy Systems
Some high-quality papers on fuzzy topics for fuzzy system and its applications can be directly published in the special issue of International Journal of Fuzzy Systems (IJFS). This journal is indexed in the Science Citation Index Expanded (SCIE, impact factor is 3.6 in 2023). Hence, we have at least a session for the special issue of International Journal of Fuzzy Systems at iFUZZY2025 conference. It will be a question-and-answer session with three reviewers for elected papers and the session is open to all the audience.
If your papers are intended for this special issue, please send emails to the guest editor (Prof. Jin-Tsong Jeng, tsong@nfu.edu.tw) when you submit your papers.

2. Journal of the Chinese Institute of Engineers
To provide a platform for timely original engineering researches and emerging technologies, the Journal of the Chinese Institute of Engineers (JCIE) is devoted to publish articles in all aspects of engineering and related fields in applied sciences ranging from fundamental principles to practical applications. Research findings and ideas published in this journal are considered with great lasting value in the engineering domain.
The JCIE is published eight times a year in January, March, April, June,July, September, October, December for effective distribution of research results. For years, our journal brings its readers the latest in technology trends as written by the very creators and innovators of those technologies. The JCIE has been recognized as one of the leading prestigious international journals. Thus, JCIE has been recorded in many widespread indexing information databases such as Aerospace & High Technology Database, Asia/Pac Bus, Jrnls, Current Contents Search, Ei Compendex, Elsevier Science's Bibliographic Database, Engineered Materials Abstracts, INSPEC, Mathsci, METADEX, SciSearch Cited Ref Sci, Social SciSearch, etc. The journal can also be found in the ISI master journal list.
