Remanufacturing　is　an　emerging　green　strategic　industry　with　resource,　economic,　and　environmental　advantages,　and　has　gradually　become　a　popular　research　topic.　The　multiple　benefits　of　remanufacturing　make　it　a　key　direction　for　its　industrial　development,　so　the　quantitative　evaluation　of　its　comprehensive　benefit　has　important　research　value.　Automotive　parts　have　a　high　remanufacturing　value　and　account　for　a　large　proportion　of　the　remanufacturing　industry,　and　thus,　they　require　systematic　benefit　evaluation　as　a　reference　for　production　decisions.　To　address　the　above　problems,　this　paper　proposes　a　multi-parameter　method　for　a　comprehensive　evaluation　of　remanufacturing　benefit　based　on　remanufacturing　process　data,　using　an　automotive　alternator　as　the　research　object.　The　method　is　developed　by　analyzing　the　remanufacturing　characteristics　and　process　of　automotive　alternators　and　constructing　a　multi-parameter　comprehensive　evaluation　indicator　of　the　remanufacturing　benefit　with　five　aspects.　The　method　uses　the　analytic　hierarchy　process　and　fuzzy　comprehensive　evaluation　for　a　comprehensive　evaluation.　Finally,　the　proposed　method　is　validated　and　analyzed　using　an　automotive　alternator　product　remanufacturing　example.　The　results　show　that　the　method　can　obtain　multi-dimensional,　detailed,　and　reliable　evaluation　results,　that　it　can　effectively　help　decision-makers　optimize　the　program,　and　that　it　has　strong　feasibility　and　effectiveness.
