The engineering,economic activities of human beings is important possible factor of induced geological hazard,in view of this characteristics,combining with the geology and exploration achievement related to Zhengzhou-Shaolinsi highway construction,form aspect of engineering geology,the possible factors of this project suffering regional geological hazard risk influence are analyzed and evaluated.

Binomial option pricing model considering stochastic factors;

An index was defined to measure relative efficiency degree of decision making units with its outputs influenced by stochastic factors.

The influence of stochastic factor and interwork effect couldn t been though about in tradition analysis and calculation of the contribution coefficient of irrigated benefit.

Theoretic capacity model considering with variable following time and random factors;

How to schedule highway engineering while considering influence of random factors was discussed,then,a new project planning technique considering effect of random factors was presented which classified those random factors and constructed different models to deal with different kinds of random factors using computer simulation technology and program evaluation and review technique(PERT).

The probability distribution of the random factor and that in thereal problems has been presented.
