Temelcan, G.T.Gonce Kocken, H.Albayrak, I.2026-01-302026-01-30202297817998922129781799892205https://doi.org/10.4018/978-1-7998-9220-5.ch118https://acikerisim2.beykoz.edu.tr/handle/123456789/255The complex system of linear equations (CSLE) has a wide range of applications in engineering, optimization, operational research, such as circuit analysis and wave equations in quantum mechanics. Since variables and/or parameters of the CSLE are generally unknown, uncertain, or imprecise in real-life applications, Fuzzy CSLE (FCSLE) arises. The fuzziness enables the modeling of the CSLE in a more natural and direct way, and thus, the FCSLE has attracted the attention of many researchers and become a significant area both in theory and application. With this motivation, a short review of the FCSLE has been conducted to guide the future studies of new researchers in this area. This review will give a general framework about the progression of the area, its solution approaches, and provide a bibliography on the topic. © 2023 by IGI Global.
