The paper presents an economic design of a bayesian chart for short-run production. Based on the static chart, we employ the bayesian method which uses sample information to update the information of the process, and the updated information is then combined with the inspection probabilistic model which is developed through the markov chain method to design the dynamic chart. The dynamic chart allows all three parameters, namely the sample interval, sample size and control limit location, to change during production. A direct search technique is applied to find the optimum parameters which minimize the expected cost function. Numerical examples illustrate that the dynamic chart has an overwhelming advantage over the static chart.

In order to investigate the change of time-frequency characteristics of vehicle/track/bridge coupling system caused by wheel tread reprofiling, a coupling model of vehicle/track/bridge system is developed, the empirical mode decomposition (EMD) and Hilbert-Huang Transformation (HHT) are introduced to the analysis of vibration signal. Based on the theory of vehicle/track/-bridge coupling dynamics, vibration acceleration of coupling system of motor car moving over bridge are calculated before and after wheel tread reprofiling, respectively. Vibration signal of coupling system is firstly decomposed into intrinsic mode functions (IMFs) by EMD method, and then Hilbert marginal spectrum is obtained from Hilbert-Huang transform. Compared with Fourier amplitude spectrum, Hilbert spectrum has higher resolution power in frequency domain in the time-frequency analysis. The simulation indicates that the proposed method is effective in the time-frequency characteristics extraction of vehicle/track/bridge coupling system.

Supply chain hybrid competition happens among two manufacturers and one traditional retailer in e-commerce age. Being a channel leader the first manufacturer's role becomes a little sophisticated. That is, being the traditional retailer's supplier and competing with the second weaker manufacturer on the internet at the same time. Besides, as an online competitor the second manufacturer's channel status could go steadily up as electronic market becomes more mature institutionally. This paper compares two kinds of game models corresponding to two different channel statuses in supply chain partners, which means a weakest traditional retailer or a weakest online manufacturer separately. It finds two models' existence conditions of supply chain partners' optimal revenues, optimal decision variables, etc. By numerical analysis it especially analyzes their products' differentiation effects. At the same time, it gives some useful managerial inspiration further.

In this paper we analysis the relation between of ownership structure and performance of the city commercial banks in China. In the analysis method and chooses data, we attention the comparability to the existing research literature. It is found that the higher the proportion of government shareholding and the proportion of the largest shareholder proportion, the poorer performance of the city commercial bank is, which is consistent to the existing majority literature search conclusion. We also found that foreign capital shareholding will reduce non-performing loans ratio of city commercial bank, but the proportion of shareholding did not have remarkable influence to the performance. Therefore, the city commercial bank do not have to introduce foreign strategic investors, may also introduce the high quality domestic strategic investor. In the end, The size of banks and ROE has a positive relationship, but the size of banks and non-performing loans ratio has a negative relationship, this indicates that under the existing environment, the city commercial bank should expand their own assets scale, and reduce the non-performing loan rate simultaneously.
