Aiming at the main problems of low loading rate of vehicles, poor arrangement efficiency of routes, high costs for distribution and collecting the parts without the time window provided by a certain vendor in the milk-run process of enterprise operation, a new mathematical model called Time Window Priority Model (TWPM) is established based on the concept of the milk run system in order to solve vehicle...
With the development of RFID technology, RFID based applications are wildly used in various fields, especially in supply chain automation. EPC (Electronic Product Code) Information Service, which takes a basic and key role in EPC network system, has become a hot research spot. How to establish highly efficient and extensible distributed EPCIS repositories is an important problem to be resolved. This...
In this paper, we generalize the Gaussian Mixture Model (GMM) in two ways: a) by introducing novel distance measures between two vectors based on nonlinear maps to give more general mixture models; b) by building mixture models based on multiple different kinds of distributions. These two generalizations cope with different problems arisen in feature modeling. Mixture model obtained by first method...
In a single-cylinder gasoline engine for the study, made a simulation optimization method of engine valve timing. After the construction of a simulation model of the engine, the simulation results are compared with the data of engine bench test to verify the accuracy of the constructed model. For improving the engine power performance, valve timing optimization simulation to this model is carried...
The physical mechanism of three-tank water level system is analyzed, and an approximated linear model is deduced to represent the dynamic property of the water level system around an equilibrium point. On the other hand, Three different identification methods based on different model structures: linear model, BP neural network model, nonlinear Hammerstein ARMAX model are used to identify the dynamical...
