# The Common Warehouse Model and Profit Distribution of the Express Industry
###### Abstract  
The sharing mode of the logistics industry can effectively solve the new problems arising from the rapid development of the express industry. However, only when the interests are reasonably distributed can the sharing mode be implemented for a long time. This paper discusses the connotation of unified warehouse and distribution, designs the operation mode of a unified warehouse and distribution, and solves the profit distribution problem of a unified warehouse and distribution alliance based on the improved Shapley value method. Firstly, the traditional Shapley value method is improved by using a comprehensive correction factor, including the proportions of investment, risk, and innovative research contributions. Secondly, each factor's weight is determined by the analytic hierarchy process (AHP), and the profits are distributed according to the contribution of each express enterprise to the alliance. Finally, an example is given to verify the validity of the modified algorithm. It proves that the modified Shapley value method can effectively solve the problem of profit distribution.

on the distribution and logistics crowdsourcing sharing mode, \"sharing\" broke the space and time limits of resources, and realized the integrated use of idle and scattered resources, thereby effectively reducing the costs of enterprise management. However, the express delivery industry in China has not formed a real scale sharing system in recent years, and some existing sharing logistics modes only achieve the common express cabinets and public outlets at the end, and each express delivery enterprise still operates independently in transportation, storage, distribution, and other operations. There are two main reasons. On the one hand, the express delivery industry is restricted by these problems:  
* Research of sharing in the field of logistics and express delivery started late, with little experience and much copying;
* Size and distribution proposals for warehouses are unreasonable;
* The degree of digital intelligence for distribution and storage areas is low;
* There are not enough effective coordination mechanisms.  
On the other hand, the industry lacks an effective incentive to promote cooperation and resource sharing between enterprises. Thus when discussing the unified warehouse and distribution, it is necessary to specifically discuss a fair and effective allocation method, in order to effectively guarantee the express companies gain greater profits from \"sharing\"--promoting the express delivery enterprises to actively participate in the sharing. Besides, it is worth noting that resource sharing is inseparable from the angle of profit distribution. Scholars adopted the Shapley value method, Raiffa method, Nash negotiation solution, and other sharing enterprises to make reasonable profit distributions to ensure the fair and stable operation of the model.  
This paper uses the existing shared logistics model for reference and combines it with the operational characteristics of the express industry to amend the Shapley value method to solve the profit distribution problem of the express enterprise alliance under this model.
