Study Of Free-riding Of Dual-channel Supply Chain With Random Demand

The development of information and network technology to promote the blowout of the online transaction. Many enterprises to consolidate offline sales channel at the same time adding the online channel, form a dual-channel mode of operation. Dual channel supply chain aroused great attention of scholars. In particular,information free-riding behavior especially worth study. In reality, a large number of consumers first went to the physical stores to experience the products, then went to the online store to purchase the corresponding products at a lower price. Now clothing store is just like the fitting room of shoppers. Visible, electronics retailer free ride on the traditional retailers information service phenomenon is very common.This article research the information service free-riding behavior of dual-channel supply chain from different angles. Mainly includes third party electronic retailer dual-channel information service free-riding behavior research.Study of the order and information free-riding of dual-channel supply chain based on CVaR criterion. Study on the decisions of order, price and promotion effort and coordination of dual-channel supply chain with information service free-riding and study of the model hybrid algorithm based on the simulated annealing algorithm(SA)and genetic algorithm(GA).The concrete research content is as follows:(1) Assume that there is defective product need to repair, the product demand is random and is affected by the retailers’ sales price and information service level, this paper sets up the decentralized and centralized decision models of order and information of supply chain with traditional channel consisting of one manufacturer and one retailer, together with one buy-back plus information service subsidy contract coordinating this supply chain. Further consider the information service free-riding behavior of one introduced e-commerce retailer, the MPEC model of decentralized decision and optimal model of centralized decision model of dualchannel supply chain are put forward by using equilibrium analysis method. The buy-back plus information service subsidy contract is presented to coordinate thisdual-channel supply chain. Final example demonstrates the reasonability of the proposed models and feasibility of the coordinative contracts. This study shows that introducing electronic sale-channel benefits the whole supply chain. The suitable information free riding behavior and the enhancement of qualified product’s rate benefit all agents of dual-channel supply chain.(2) Consider one dual-channel supply chain(DCSC) consisting of one manufacturer and one retailer who take charge of the direct-sale on internet and the traditional retail respectively. Assume that the demand is random and dependent on retailer’s information service level, the information free-riding behavior of the direct-sale channel to retail channel is studied. This paper firstly sets up the centralized and decentralized decision models of DCSC with risk-neutral manufacturer and retailer.One buy-back plus information service subsidy contract is obtained to coordinate this DCSC. Based on CVaR criterion, the centralized and decentralized decision models of DCSC with risk-averse manufacturer and retailer are put forward, together with the correspondent buy-back plus information service subsidy coordinative contract.Final example demonstrates the reasonability of the proposed models and feasibility of the coordinative contracts. The study shows that the enhancement of information free-riding behavior of direct-sale channel benefits all agents; the more risk-averse decision-makers are, the less order quantities are, which lowers the profits of manufacturer, retailer and whole supply chain;, the decisions of DCSC with risk-averse decision-makers are identical to those with risk-neutral members when the risk-averse factor equals to one.(3) Assume that the product demand is random and is affected by the retailers’ sales price and promotion effort level, this paper sets up the decentralized and centralized decision models of order, price and promotion effort of supply chain with traditional channel consisting of one manufacturer and one retailer, together with one profit share contract coordinating this supply chain. Further consider the mutual service free-riding behavior of one introduced direct channel producer, the model of decentralized decision and optimal model of centralized decision model of dual-channel supply chain are put forward by using equilibrium analysis method.HSAGA is designed to solve the bilevel programming model. The profit sharecontract is also presented to coordinate this dual-channel supply chain. Final example demonstrates the reasonability of the proposed models and feasibility of the coordinative contracts. This study shows that HSAGA is effective to solve the dual-channel supply chain problem and introducing direct channel is benefit to the whole supply chain. The excessive service free riding behavior is not benefit to dual-channel supply chain.First, the existing study of dual channel supply chain rarely consider random demand situation. In this paper, we study dual-channel supply chain based on random demand situation. In addition, the innovation of this paper include:(1) Considering factors such as product ordering and information service decision, dual-channel supply chain structure exist with a third party E-commerce retailer, defective products recycling remanufacturing, information free-riding behavior.(2)Considering factors such as product ordering and information service decision,dual-channel supply chain structure exist of manufactuer direct selling, CVaR risk measurement standards, information free-riding behavior.(3) Further consider the product price decision. For it is difficult to solve explicit expression when solve the mathematical model. We innovative design for a class of algorithm hybrided by SA and GA to solve the dual-channel supply chain model.
