In order to stabilize the required overload of last ballistic paragraph for the interception of high-speed and high-mobility targets, two types of three-dimensional adaptive proportional guidance algorithm are proposed in this paper. Through the establishment of three-dimensional kinematics equations which describe the moving relationships of the missile and target, the acceleration and velocity direction...
This paper focuses on the change in damping characteristics of interconnected bulk power grids before and after UHV extension project, and makes a check of the dominant oscillation mode by means of eigenvalue method and prony analysis method. Such two analysis methods are applied in the North and Central China interconnected grids which are linked through UHV line. The results show that frequency...
In this paper, we consider an extension to the dual model under a barrier strategy, in which the innovation sizes depend on the innovation time via the FGM copula. We derive a renewal equation for the expected total discounted dividends until ruin. Some differential equations and closed form expressions are given for exponential innovation sizes. Finally, a numerical example is given.
Matching of parts of solar heat pump unit plays an important role on system design and selection of operation scheme. Steady state distribution model of evaporator is built and algorithm flow of simulation is designed with reasonable hypothesis. The steady state distribution model is simplified association with RBF and BP neural network. The optimization model is obtained with using correction method...
The importance of recycle center to reverse logistics is just like that of distribution to forward logistics. And the location selection of recycle center directly impacts on the performance of the reverse logistics management. A hybrid model combining AHP and DEA methodologies is given here. AHP is used to determine the comprehensive benefit of each alternative location of recycle center. And then...
In the conceptual design stage of excavator, there are many uncertain information so that the quantitative evaluation of design schemes is very difficult. Traditional AHP (analytic hierarchy process) method can’t deal with the multi-attribute problem with uncertainty, so the FAHP (fuzzy analytic hierarchy process) is presented. And then, the hierarchical evaluation structure is constructed. In the...
