By using the (alpha-beta )-level set of intuitionistic fuzzy numbers and Zadeh's extension principle, the FBVP is solved with the proposed method. Furthermore, a numerical example is illustrated and the advantages of the proposed approach are compared with other well-known methods such as the solutions based on the generalized Hukuhara derivative.eninfo:eu-repo/semantics/openAccessHeaviside functionEigenvalueFuzzy eigenfunctionZadeh's extension principleArticle14322022810.11121/ijocta.1471Q21252654WOS:001267413600005N/A
