As the rapid development of wireless communication technologies and the widespread popularity of smart terminals, traffic and demands of the mobile network grow exponentially, moreover the deployment of small cells in current heterogeneous networks becomes denser and denser. These bring lots of signaling overhead and too much energy consumption, in addition these challenge the robustness of mobile...
Because of drawing of aerospace task and requirement of technical development, more autonomy and intelligence of spacecraft is needed and it is also for the cooperation of ground systems. According to requirements and the state of art of existing research, firstly a universal autonomous cooperative control process is brought forward, then an autonomous cooperative cognitive architecture is designed,...
For features of planning and design's evaluation, and on basis of the principles of establishing evaluation index system, this paper established the comprehensive evaluation index system of residential planning and design program; In the use of analytical hierarchy process to determine weights of evaluation indexes, and based on the character of fuzzy comprehensive evaluation method that using dimensionless...
CUSCORE control chart is designed based on the thought of CUSCORE statistic to control the non-stationary autocorrelated process IMA (1, 1). The MMSE method is used to remove the auto-correlation among the observations. By comparing the performance of CUSCORE control chart to Shewhart Control Chart, the CUSCORE control is more effective in the case of the process mean drifting.
Multiple attribute decision-making theory under uncertainty is an important part of decision making theory, in this paper, a grey multiple attribute decision-making approach is proposed to study multi-criteria decision-making problems under uncertainty in which criteria values are interval gray numbers. Using grey related analysis as a means to reflect uncertainty in multiple attribute models through...
Product design which is one of the most important stages for manufacturing is a complex activity involving a great amount of knowledge. In this paper, knowledge is divided into three types: formula knowledge, diagram knowledge, table knowledge. Based on these requirements, knowledge base is constructed. This is used to store knowledge and to support the decision-making product design. First, the knowledge...
The comprehensive business includes many links, and the radical of agile networked manufacturing is reducing cost and improving agility for manufacturing enterprises. So,in order to form an agile networked manufacturing system, it needs selecting appropriate partners in every link. But it is difficult to select from so large number of partners. Genetic algorithm is a method for resolving combinatorial...
A risk assessment method is introduced to the estimation of network security. The method, which combines AHP method and fuzzy logical method, is applied to the risk assessment. AHP method and fuzzy logical method are improved according to the actual condition of the risk assessment of network security. Each risk factor is estimated in the aspect of the probability, the impact severity and uncontrollability...
