Aiming at the problem that the traditional reliability method with small failure samples cannot accurately calculate the reliability, this paper makes full use of existing information and expert information, etc. Based on the combination of prior information and constrained no prior information, the improved Bayesian method is used to establish reliability. Sexual analysis model. First, a weighted fusion method is used to establish a joint prior distribution that combines prior information with constrained and no prior information according to the credibility of the prior information to the posterior information. At the same time, the robustness of the joint prior distribution is analyzed; The prior distribution is combined with the posterior information to calculate the posterior distribution form of the distribution parameter, and the distribution parameter value and the mean time between failures are calculated.

As the backbone of China’s economic development, the procurement of state-owned enterprises has a far-reaching impact on the breadth and depth of the whole procurement field. With the rapid development of China’s economy and the accelerating pace of GPA accession, the role of procurement in the supply chain of Chinese state-owned enterprises has become more prominent. Based on the procurement dilemma of Chinese state-owned enterprises and the characteristics of procurement under the supply chain environment, this paper dialectically analyzes the relationship among supply chain management and procurement of Chinese state-owned enterprises, and compares the advantages and disadvantages of the general framework agreement procurement method and the bidding framework agreement procurement method from the perspective of supply chain procurement. On this basis, it explores that the consignment bidding framework agreement procurement is an effective way to optimize the procurement method of Chinese state-owned enterprises.

The view of semantic activation provides a fair cognitive basis for English vague ambiguous sentences. Integrating the access-and-activation model with a chain of reference point relationships, this paper constructs an access and spreading activation network model of reference point relationships to probe into the cognitive interpretation of vague ambiguous sentences. Results indicate that the double-decoding conceptualization process involves the reference point’s activating and spreading to the target. Vague ambiguity takes place at the levels of lexeme, lemma and conceptual level. The research may shed new light on cognitive linguistics, language education and computer processing of natural language.

The issue of college students' entrepreneurship and employment has always been a headache for the government. How to solve this problem is about social stability and people's happiness. And it's up to 89 colleges & universities and 1.3 million college students in WuHan, the number of college students is at the forefront of the world's single cities, it's situation of college students' entrepreneurship and employment in Wuhan can reflect the employment and entrepreneurship of contemporary Chinese college students. So research team took Wuhan as an example. The phenomenon of "going away" is serious in Wuhan. In the past 5 years, less than 50% of Chinese students have been studying in the past five years. To solve this problem, the Wuhan government has launched the "Millions of College Students to Start Businesses and Employment Program" since the "Qingtong" project. The purpose is to enable millions of college students to "come in, go on, stay, and do" in Wuhan. Through field research and case interviews of universities such as Huazhong University of Science and Technology, Wuhan University and Wuhan University of Technology, this paper analyzes the status quo of college students' innovation and entrepreneurship, points out their problems, analyzes the causes, and finally puts forward four suggestions. Aim to make a small contribution to the innovation and entrepreneurship of millions of college students, and solve some problems for the innovative and entrepreneurial students.

It’s difficult to obtain and standardize the contractor capacity information during the process of the military equipment contractor evaluation. This paper analyzed 8 main influencing factors of contractor capacity and established a comprehensive evaluation model of military equipment contractor capacity based on grey target decision theory. Taking the military software production and development project as an example, the evaluation model was used to evaluate the capacity of five contractors, and the effectiveness of the model was verified. The evaluation model realized the comprehensive evaluation of the qualified influencing factors of the contractor capacity, and put forward an effective method to evaluate contractor capacity under the limited sample information situation.

Inspired by recent academic advancement as well as real-world cases on hedge fund activism, the main purpose of this paper is to verify the potential effects of hedge fund activism on target firm’s CEO compensation. We used Propensity Score Matching and Difference-in-Differences approach to conduct the statistical analysis based on 835 analyzed samples. We found that the difference between the previous CEO pay level before hedge fund’s intervention and the post CEO pay level after hedge fund’s intervention for target firms is smaller compared to that for non-target firms. The result provides new evidence for the argument that the hedge fund’s intervention can be effective in suppressing the increase in CEO pay in hedge fund’s target firm. The study reveals a possibility that the hedge fund’s involvement in target firm can be viewed as a solution to adjust the executive pay to the reasonable level and make the executive compensation structure more based on company performance.

With the signing of the China-Korea bilateral free trade agreement in 2015, the relationship between China and South Korea's trading partners has been further clarified. However, China's trade account with South Korea has been in deficit for successive years, and as South Korea's direct investment in China has increased, the deficit has become more apparent. Based on the introduction of the status of South Korea's direct investment in China and China-South Korea trade, this article analyzes the theoretical mechanism and empirical analysis of the impact of South Korea's direct investment in China on the China-South Korea trade deficit, and makes relevant suggestions for reducing the China-South Korea trade deficit.

The price of oil, known as "black gold", has always attracted the attention of countries around the world. It is already a consensus that international oil prices affect economic operations, and naturally will affect the stock market which is regarded as a barometer of economic operations. The purpose of writing this article is to reveal the impact of international crude oil price fluctuations on China's stock market. In order to solve this problem, the author of this paper selected two sets of time series of Brent crude oil spot price and Shanghai Stock Index, and used Eviews software to perform various econometric tests such as cointegration test, Granger causality test, impulse response function, and decomposition of variance. It is found that there is a long-term stable cointegration relationship between the international oil price and the Shanghai Stock Index, and that the international oil price is the Granger cause of the Shanghai Stock Index. Furthermore, the former has a positive dynamic impact on the latter as a whole. It reached its maximum by the middle of the third month, and then slowly decreased to stabilize. Compared with the results of other similar studies, this article draws more accurate conclusions thanks to the latest, more realistic data without much artificial processing. The conclusions of this paper can help stock investors and economic decision makers to make more effective decisions.
