In order to evaluate the projects, nine sub-criteria were considered which were classified into three categories of business, finance and procedural ones. Also to consider the ambiguity related to the pairwise comparisons being used in the research, the fuzzy logic was employed. The fuzzy algorithm being used is in the method of Mikhailov which has various advantages such as the presentation of consistency index and weight vector in a crisp form. At the end, in order to show the applicability, the proposed methodology was applied in an automobile part manufacturing firm</font></span><span style="FONT-SIZE: 10pt COLOR: black FONT-FAMILY: "Times New Roman" mso-fareast-font-family: 'Times New Roman' mso-ansi-language: EN-US mso-fareast-language: EN-US mso-bidi-language: FA mso-bidi-font-style: italic">.</span></em> Fuzzy analytic network process, Project selection, Six-Sigma 157 164 http://ijiepr.iust.ac.ir/browse.php?a_code=A-10-1-58&slc_lang=en&sid=1 Hosein Saghaei a.saghaei@srbiau.ac.ir 180031947532846003107 180031947532846003107 Yes Hosein Didehkhani hoseindidehkhani@gmail.com 180031947532846003108 180031947532846003108 No
