In cloud computing environment, there is a large quantity of submitted tasks by users. How to schedule these massive tasks efficiently and reasonably becomes a serious challenge. This paper proposes a Chaotic Particle Swarm Optimization algorithm (CPSO) to overcome the problems of Standard Particle Swarm algorithm such as premature convergence and low accuracy. Firstly, in initial process, chaotic...
In the daily audit work, informationization brings huge amounts of business data. Auditors face huge amounts of data, and personnel allocation has no planned way. In order to solve these practical problems, we introduce the data mining technology. Isolated point algorithm based on unit is applied to computer network audit. Boundary cell value of the isolated point algorithm is adjusted. By means of...
Based on the market demand and the competition pressure, using the value chain theory and multi level structural analysis model as the main direction of drug control, and analysis the dual reconstruction properties proceeding from numerical fitting of a resource and a variety of resources. Finally, on the basis of the analysis of the integrated management organization mode, the reconstruction is put...

Far infrared convection combined heat transfer was discussed in detail, the test...
Hybrid electric car fuel consumption optimization based on fuzzy control strategy has strong subjective dependence, and the control results cannot reach the most optimal value. So a kind of improved genetic algorithm is introduced into optimization of control rule. According to genetic algorithm theory, the vehicle fuel consumption and emissions are taken as the objective function and fitness function...
In order to achieve the goal of economic and environmental mutual optimization of micro-grid system operation, a general model of multi-objective dynamic optimal scheduling is established, which takes the independent system simulation module and the operation optimization module as the core. The simulation module uses energy model to evaluate economic and environmental indexes of the system scheduling...
