To　effectively　solve　the　overstock　problem　of　apparel　products,　in　consideration　of　customers＇　preferences　for　product　availability　and　the　strategies　differentiation　of　supply　chain　in　different　stages,　the　0-1　mixed　integer　dynamic　programming　model　was　constructed　with　the　maximum　profit　in　entire　cycle　by　introducing　presale　mode.　Under　presale　and　non-presale　modes,　the　decision　variables,　profits　and　related　parameters＇　sensitivity　of　dual-channel　supply　chain　at　each　stage　were　made　comparative　analysis　with　numerical　examples.　The　results　showed　that　the　coordinated　operation　of　dual-channel　supply　chain　network　based　on　presale　mode　effectively　reduced　the　inventory　amount　and　shortage　amount　of　products　simultaneously　under　certain　circumstances.　©　2016,　CIMS.　All　right　reserved.
