en عمومى General پژوهشي Research paper <div style="text-align: justify;">In this study, we employ fuzzy Sumudu transform to find the solution for system of linear fuzzy differential equations where the system possesses fuzzy constant coeffcients instead of crisp. For this purpose, fuzzy Sumudu transform has been revisited and a brief comparison with fuzzy Laplace transform is provided alongside, particularly on the scale preserving property. For the sake of comparison, we introduce to the literature a time scaling theorem for fuzzy Laplace transform. Next, the system with fuzzy constant coeffcients is interpreted under the strongly generalized differentiability. From here, new procedures for solving the systems are proposed. A numerical example is then carried out for solving a system adapted from fuzzy radioactive decay model. Conclusion is drawn in the last section and some potential research directions are given.</div> Fuzzy Sumudu transform, Fuzzy differential equations, System of fuzzy differential equations, Fuzzy Laplace transform, Radioactive decay model. 79 100 http://ijmsi.ir/browse.php?a_code=A-10-5631-1&slc_lang=en&sid=1 N.
