Research On Coordination Of Logistics Service Supply Chain Under Contracts Based Stochastic Yield And Demand

In this paper,we focus on the problem of the logistics service supply chain composed of "logistics service function provider? logistics service integrator?customer",and we analyze it with mathematical analysis,operational research,game theory and so on.By drawing lessons from the contract coordination theory of traditional supply chain,we research the coordination of logistics service supply chain under uncertain output,uncertain demand and simultaneous uncertain output and demand.The main contents and conclusions of this paper are as follows:Firstly,we study the problem of the coordination of logistics service supply chain with stochastic output.In this case,a coordination model of logistics service supply chain based on the contracts of the capacity surplus risk sharing contract and the capability deficiency penalty is constructed.The results show that:the ability surplus risk sharing contract can reduce the risk of logistics service function provider,and the function provider can reduce the investment reserve of logistics service ability.Meanwhile,the penalty contract increases the risk of logistics service providers.In order to avoid punishment,this mechanism can stimulate the logistics service providers to increase their logistics service capacity and investment reserves,which will improve the output of logistics service capacity.Both capability surplus risk sharing contract and capability deficiency penalty contract can realize the free distribution of revenue between logistics service providers and integrators.The profit distribution coefficient depends on the negotiation ability of logistics service integrator and function provider,which reflects the flexibility of logistics service supply chain.Secondly,we research the problem of the coordination of logistics service supply chain under stochastic demand.In this case,we analyze the demand patterns of linear demand and elastic demand.Combing with the revenue sharing,price discount and the effort cost sharing contract in the supply chain,we propose three new coordination mechanisms:direct feedback revenue sharing coordination contract,multi-level feedback coordination contract and direct feedback effort level sharing coordination contract.The results show that whether it is linear demand model or elastic demand model,the direct feedback revenue can share the coordination contract,the multi-level feedback coordination contract can realize the coordination of logistics service supply chain and the direct feedback effort sharing coordination contract can only achieve the coordination of logistics service supply chain under the linear demand model while it cannot get the coordination of logistics service supply chain under the mode of elastic demand.In the linear demand model,the logistics service providers prefer both the direct feedback revenue sharing coordination contract and the direct feedback effort level sharing contract while the logistics service integrators prefer the multi-level feedback coordination contract.For the mode of elastic demand,the logistics service providers prefer multi-level feedback coordination contract,and the logistics service integrators tend to adopt direct feedback revenue sharing coordination contract.Finally,we analyze the problem of the coordination of logistics service supply chain with stochastic output and demand.In this case,a flexible ordering strategy is proposed for the situation of uncertain output and demand,meanwhile,a joint coordination strategy of penalty feedback contract based on the revenue sharing contract is also proposed.The results show that the flexible ordering strategy can not only reduce the uncertainty of logistics service supply chain,but also can improve the overall revenue level of logistics service supply chain by coordinating contracts in the output and demand uncertain case.The revenue growth rate of logistics service supply chain increases with the increase of output uncertainty and demand uncertainty.The penalty feedback joint coordination contract based on revenue sharing contract can realize the coordination of logistics service supply chain.The logistics service providers and integrators can realize the reasonable distribution of revenue in logistics service supply chain by adjusting the revenue sharing coefficient.
