Abstract: Crowdsourcing supply chain as a new type of supply chain under Internet plus is becoming a hot topic in today's research.Aiming at the problem that few researches focuses on integration of upstream crowdsourcing and downstream production,the basic model of supply chain based on crowdsourcing was established by embedding the crowdsourcing design link into supply chain.On this basis,the influence of the accuracy in customized demand information on the quality of crowdsourcing design decisions was considered to extend the basic model to crowdsourcing supply chain design under the information update,and the production quantity under two design policies—Initial Design(ID) and Modified Design(MD) were obtained respectively.Two different design policies would inevitably cause the downstream supply chain manufacturers to respond accordingly,so three combination strategies of crowdsourcing supply chain that were ID and Postpone Production (PP) policy,MD and Instant Production (IP) policy and MD and PP policy were discussed.The optimal production quantity and implementation prerequisite under three combination policies were obtained.Through the example,the different combination policies were compared and analyzed,the results showed that MD & PP was the best,followed by MD & IP and ID & PP.The sensitivity analysis was used to further confirm effectiveness of the models.
