Profit Allocation of Agricultural Machinery Service-Oriented Manufacturing Alliance Based on Modified Shapley Value Method

Shapely value is a method of determining the importance of individuals in the collective, avoiding the equal allocation of profit. The profit allocation on SOM (service-oriented manufacturing) alliance between agricultural machinery manufacturing enterprises and suppliers under the SOM mode is a complex problem restricted by many factors, but the Shapely value method does not consider the differences of member enterprises. Therefore, factors that affect the profit allocation are given in this paper, such as input level, effort level, innovation level, risk factor, and value-added factor. Based on these factors, the Euclidean distance is used to modify the traditional TOPSIS method to determine the profit allocation correction coefficient, and the GRA (grey relational analysis) is introduced into the TOPSIS method to calculate the closeness degree, which reflects the position relationship and consistency of data curve. Based on the modified Shapley value method, a profit allocation method of agricultural machinery service-oriented manufacturing alliance is constructed. Finally, an application example is given to verify the effectiveness of the proposed method.

The Measures Contribution Researches on Renewable Energy Accommodation Based on Production Simulation

This paper presents the impacts of load, source and grid factors on renewable energy accommodation in the northern region of China. Renewable energy curtailment reasons and key measures to improve accommodations are also discussed. The production simulation method is utilized to analysis renewable energy accommodation and the Shapely value method is introduced to calculate the accommodation contribution rate of different factors. The result shows that the amount of renewable energy accommodation is 389 TWh in northern region of China by the year 2020. The contribution rate of load, source and grid factors to renewable energy accommodation are 39%, 35.8% and 25.1%, respectively.

Comprehensive Benefit Allocation for Joint Operation of Multiple Reservoirs in the Ningbo Based on Shapely-Value Method and Benefit-Incremental Method

With the completion of interconnection project of the Eastern Reservoir Group, it is possible to realize the joint operation of the multiple reservoirs in the Ningbo, and integrated dispatching involving water supply and power generation has significant benefits. Based on the inequality of multi-stakeholders and the irrationality of benefit allocation in the cascade reservoir, this paper takes the joint operation of three reservoirs in Ningbo as an example and establishes a Shapley-value and benefit-incremental model, aiming at quantifying and sharing the compensation benefits. Results show that this method not only has strong operability, but also it has clear objectives that can be quantified. Moreover, this method takes the actual contribution value of different stakeholders into consideration. Thus, adopting this method is able to give full play to the enthusiasm of different reservoirs and achieve the maximum comprehensive benefit of the reservoir group.
