Collusion behaviors in the market are divided into three types: rotation, price alliance and compensation bid. Constructing AHP-Fuzzy model evaluates bidders’ parallel string behaviors. It is judged with the aid of grey correlation analysis and fuzzy comprehensive evaluation. Price correlation, price rationality and the annual output value rate of the total assets are taken as influence factors of comprehensive evaluation. Finally, an example proves the correctness and effectiveness of the model.

Temperature Radiation

In order to accurately simulate the combined action of rainfall, high temperature and sunshine effect on asphalt mixture, the experiment of water-temperature-radiation circulation was designed. The changes of air void, split tensile strength, freeze-thaw splitting tensile strength and dynamic stability were quantitatively analyzed under the condition of different asphalt-aggregate ratio and different striking times during water-temperature-radiation cycle. Grey correlation analysis method was used to analyze the influence factors of the four parameters mentioned above, and comprehensive correlation was put forward to evaluate the influence factors of mechanical properties of asphalt mixture. It is proven that, the cycle index of water-temperature-radiation is the main factor. The striking times and asphalt-aggregate ratio influence mechanical properties of asphalt mixture less than the cycle index, and the initial void influences least.

In order to forecast the using life of the armored vehicle engine synthetically, the index system of the armored vehicle engine using influence factors is established by means of the relativity analysis method, while the weightiness values of the indexes are calculated out by AHP. Taken as similar systems, different engine using environments are evaluated quantificationally in applying of the similar system theory and its measurement, and the actual consumable of motor hour for the engine under different using conditions is figured out defining the engine using condition correctional coefficient. As a result, the right weightiness matrix of the engine using influence factor indexes as well as the calculation method of evaluating the armored vehicle engine life under different using conditions is given. The feasibility and validity of the method is proved by the instance calculated.

Durability Of Concrete

In this paper, under the environment of saline soil in the western region of Jilin Province, a series tests research on the durability of concrete has been made. The test results show that: there are a lot of factors that influence the durability of concrete, including the concrete itself internal factors and the external environmental factors. The correlation degrees between these influence factors and the durability of concrete are uncertain. In this paper, a grey correlation degree method has been used to analyze the correlation degrees between these influence factors and the dynamic elastic modulus loss rates of concrete, in order to determine the influence degree of each factor on the durability of concrete.

Grey Correlation Theory

Concrete structures durability is affected by a number of factors which have different sensitivity. According to level of sensitivity classified the influence factors could promote concrete structures durability design. The disadvantage of traditional methods of sensitivity analysis in concrete structures durability is the larger number of samples. The grey correlation theory was used to analyze the degree of the sensitivity of the influence factors and comparison with traditional methods of calculation. The results show that the grey correlation analysis method could quantify the levels of the sensitive factors and with higher reliability. A new way to study the durability of concrete structures was provided.
