Dynamic programming algorithm was introduced to solve the problem. Based on discussion of calculation complexity and effectiveness, the exact DP Algorithm was successfully used in operative schedule of the collecting bucket in multi-car-single-layer mode, which has few service nodes. For problems with large number of service nodes, restricted DP algorithm was constructed to avoid rapid expand in calculation and memory demands during programming process. The restricted DP algorithm, successfully used in single-car-multilayer and compound service modes, gets balance between near optimal programming results and reasonable programming time, so as to meet the real time schedule demands.

It has become the restrictive factor of economic development. The implement of water saving rebuild programming in northern droughty areas is an important measure for sustainable use of water.This study is based on the investigation of the type, step and method of SEA, and focuses on the water saving rebuild programming in Mongolia Hetao regions as a case. The SEA technique is applied to agricultural sustaining using of water. The contents and impact factors are summarized along with the objective and standards defined clearly. This paper also offers assessment indexs on water saving rebuild programming, which evaluates the subsequent environmental impacts and public benefits. Some measures avoiding the negative impact are also presented to ensure that this programming is in accordance with the principle of sustainable development.

Firstly, an empirical approximation model of stochastic programming is obtained by replacing the probability measure of original program with empirical probability measure. Sequentially, the constrained stochastic programming is transformed into an equivalent unconstrained stochastic programming. Finally, using the epi-convergence theory, the almost everywhere upper semiconvergence of optimal solution set of empirical approximations for stochastic programming is obtained.

The mathematical programming formulation and related solution procedure are established by the traditional BEM. Through the discretization of space and time, the elastoplastic stress simulation method and reduce-basis technique are adopted to construct the self-equilibrium stress field. The numbers of variables and constraint equations in the resulting mathematical programming formulation are reduced greatly and then the dimension obstacle of computation in 3-D limit and shakedown analysis is overcome.
