The Chinese automotive industry is the largest in the world. Although after-sales services are known to be associated with profitability, it has not obtained its rightful prominence in the Chinese industry. To investigate how the quality of leader-member exchange can influence after-sales services in the Chinese automobile industry, we collected data from individual employees and customers and analyzed it using grey theory model. Based on the results, we proposed the industry to pay more attentions to tangible after-sales service. While previous studies tended to adopt an either customer or employee perspective, our research contributes to the literature by offering a more comprehensive perspective from both the standpoints of the organization and consumers, and our grey theory analytic approach offers a viable option for researchers who are interested in reducing biases in data due to the data aggregation process.

While the Chinese banks have started the impact of foreign banks. At the same time, rising pressure on foreign exchange reserves and appreciation of the renminbi has prompted Chinese banks to go abroad and diversify their risks. The financial crisis of 2008 has caused the continued turbulence of the major financial markets around the world, and the valuation of foreign financial institutions has been drastically shrinking, providing opportunities for Chinese banks to carry out overseas M&A. Based on the overseas M&A status of Chinese commercial banks, this paper sums up the characteristics of the overseas M&A. Then taking a series of overseas M&A conducted by ICBC from 2006 to 2011 as an example, it analyzes the relationship between M&A and performance growth using grey incidence model. The test shows: there is a positive correlation between both overseas M&A and interest rate differential with performance growth of ICBC, and overseas M&A transactions role in promoting the performance growth is significantly higher than the interest rate differential.

While the Chinese banks have started the impact of foreign banks, overseas merger and acquisition of commercial banks also have emerged a way of capital transnational movement. At the same time, rising pressure on foreign exchange reserves and appreciation of the renminbi has prompted Chinese banks to go abroad and diversify their risks.

Aimed at the subjectivity of selecting the weight of each objective function in the process of multiobjective reliability-based design optimization (MRBDO), this study proposed a multiobjective weight quantitative analysis method by combining the gray incidence analysis method and evidence theory. This method derived the weight of each objective function from the uncertainty information of design variables, and effectively avoided the subjectivity of weight selection. First, the ideal attribute interval number and the interval number matrix of uncertain design variables were defined based on the gray system theory. On the basis of the definition of the information structure sequence, the gray incidence coefficient (GIC) matrix of measures with ideal attribute deviations was derived. Second, the basic probability assignment of each objective function and model under uncertainty variables was derived based on the DempsterShafer evidence theory. The Dempster-Shafer evidence synthesis rule was used to fuse the multisource evidence information to obtain the weight of each objective function. Then, an MRBDO problem was converted into a single-objective reliability-based design optimization (SRBDO) problem, which is relatively easier to address. Third, the performance measurement analysis (PMA) method was used to transform the reliability constraint into an optimized iterative process, and the MRBDO solution was obtained based on the MATLAB Optimization Toolbox and Symbol Toolbox. Finally, the accuracy and efficiency of the proposed method were verified through a numerical example and a small aeroengine gear reduction system.
