Alpha-reliable combined mean traffic equilibrium model with stochastic travel timesZHANG Wen-yi(张文义), GUAN Wei(关伟), SONG Li-ying(宋丽英), SUN Hui-jun(孙会君) (Key Laboratory for Urban Transportation... travel time index named combined mean travel time (CMTT) under stochastic traffic network was proposed. CMTT here was defined as the convex combination of the conditional expectations of PTT-below......
stochastic and time-dependent (STD). The methodology of relative robust optimization was applied as measures for comparing time-varying, random path travel times for a priori optimization. In accordance with the situation in real world, a stochastic consistent condition was provided for the STD networks and under this condition, a mathematical proof was given that the STD robust optimal path problem can......

Markov chain simulation, however, is still under development, mainly because......
. The rock and soil around pipe-jacking tunnel is considered as a stochastic medium, the movement of the soil due to tunnel excavation or squeeze is considered as a stochastic process and the stochastic medium theory is applied to analyse and calculate the movement and deformation in the disturbance area due to pipe-jacking construction. The formulas of rock and soil′s subsidence, horizontal......

to study the uplifting effect of compensation grouting on ground surface and the upper structures, the ground heave induced by stratum expansion was considered as a stochastic process and the stochastic... than that from uniform expansion for shallow grouting, both of them tend to be convergent with the increasing of grouting depth. Key words: grouting; ground surface uplifting; stochastic medium theory......

2006 Abstract: A stochastic model for simulating the microstructure formation of Mg alloy AZ91 during solidification was developed based on the finite element method(FEM) for macroscopic model..., such as nucleation parameters and heat transfer coefficient, on the microstructure formation of AZ91. The result of simulation was displayed on screen. Key words: AZ91; FEM; cellular automaton; stochastic......
