Indices factors decomposition method is used to decompose the factors affecting electricity consumption into four effects: structure effect, quantity effect, intensity effect, structure effect of power consumption. It is considered that the structure effect and the quantity effect are the critical factors to affect the total indices of electricity consumption. Further more, total indices of electricity...
The simulated experiments are generally adopted to study the control performance of earth-pressure-balance system of shield machine economically and safely. But, the range and strength of simulated experiments are usually restricted by the physical conditions of simulated system. In this study, the simulation model of earth-pressure-balance simulated system of shield machine was established based...
Decision-making information often has uncertainty because of inaccurate estimate and survey error. This causes the quantification of information to appear in the form of intervals. To solve the multiple attribute decision-making issues of interval number, a new method based on fuzzy theory is put forward. On the basis of this method, different schemes of the water resources allocation in a certain...
A Hinfin filter based on GPS dynamic locating method is put forward in this paper. The proposed method is able to decrease the current acceleration model error. Some examples show that the method can perform better in GPS dynamic locating than EKF for less computation consumption and higher locating accuracy.
