Nowadays,　knowledge　has　become　one　of　the　most　important　tools　of　power,　distributing　public　services　that　accept　the　audience　as　citizens　and　not　consumers　and　provide　the　principle　of　services　without　financial　worries.　Moreover,　the　urban　products　have　a　specific　production　and　distribution　channel　that　should　be　assessed.　In　this　research,　a　mathematical　framework　is　proposed　for　designing　the　supply　chain　network　of　urban　products.　The　main　contribution　of　this　research　is　to　incorporate　the　e.ect　of　public　service　into　urban　products＇　supply　chain　planning.　In　this　regard,　a　mixed-integer　mathematical　model　is　proposed.　In　this　mathematical　model,　an　attempt　is　made　to　minimize　the　costs　of　the　product　distribution　system　by　considering　the　e.ects　of　production,　maintenance,　and　distribution.　Moreover,　fuzzy　uncertainty　has　been　applied　to　adapt　the　mathematical　model　to　real　conditions.　The　numerical　results　show　that　if　manufacturers　and　distributors　want　to　strengthen　their　institutions　and　maintain　their　leadership　roles　as　in　the　past,　they　can　optimize　their　distribution　network　structure　to　achieve　the　best　possible　performance.　Moreover,　technological　advances　and　innovations　in　production　and　distribution　systems　can　create　a　huge　leap　in　profltability.
