Revenue sharing contract collaborative mechanism in supply chain

In a two-stage supply chain composed of two manufacturers and one dominant retailer, the supply chain revenue sharing contract collaborative mechanism is researched under a fuzzy and pricedepended demand environment. Result shows that under the fuzzy demand environment,the double marginalization effect still exists in the many-to-one and retailer-dominant supply chain,and revenue sharing contract mechanism can achieve supply chain collaboration; meanwhile,both Income distribution coefficient and the profits of the whole supply chain have a positive relationship with the substitutability between products.
