Abstract:As a new kind of supply chain with "Internet + innovation", crowdsourcing supply chain is becoming a hot topic in today''s research.Different from traditional enterprises to develop new products. When crowdsourcing supply chain enterprises face the Internet characteristics of online design products, there are many problems such as online mass design participants and consumers'' emphasis on experiential and design production. And crowdsourcing supply chain has the characteristics of leveraging Internet, mass participation and participatory heterogeneity, making it contains potential risks different from the traditional supply chain. This paper based on the Fuzzy-owa operator for analysis, from the perspective of supply chain, including the crowdsourcing design, supply, manufacturing to evaluate the risk of new product development in the crowdsourcing supply chain and establish Dematel model. On this basis, we analyze the logical relationship between the main risks based on the reasons and results, find out the main risk factors that affect the development of the crowdsourcing supply chain, and give some suggestions according to the results of the model analysis.
