Most evolutionary algorithms utilize the posteriori knowledge learned from the running process to guide the search. It is arguable that the priori knowledge about the problems to tackle can also play an important role in problem solving. To demonstrate the importance of both priori and posteriori knowledge, in this paper, we proposes a decomposition based estimation of distribution algorithm with...
To solve the cumbersome authorization, heavy workload and such problems which exposed in practical applications of the web application access control, the paper introduces a new access control model based on web application(WRBAC). The model classifies the object directly of web application, which can reduce the difficulty of assigning permission between roles and objects. The model improves the efficiency...
Based on customer-oriented e-commerce flow, this paper analyses the knowledge of e-commerce flow and builds e-commerce domain ontology and sub-ontology. Based on this analysis, this paper builds reusable model of e-commerce domain ontology by using ontology construction standard technology. This reusable model can reveal the knowledge and the relationship between knowledge of the e-commerce flow deeply...
An analysis for individual behaviour in group formation is shown in this paper. We find that individuals adjust their states by means of pulse during the group formation. An explanation for this phenomenon is proposed by studying the characteristics of these oscillations, that is, when group is in dynamic equilibrium, it's change of state will be passed to the individual in the form of fluctuation...
The specific transmission and diffusion of emergency in supply chain is determined by the characteristics of complexity, multitudiousness and diversification of stakeholders of supply chain. This paper analyzed the diffusion traits, patterns and influencing factors of emergency in supply chain. The incubation period, fast outbreak period and slow diffusion mechanism of emergency in supply chain are...
To identify and eliminate the product's early failures with the lowest cost and the best effect, this paper proposes a HASS profile research method based on computer simulation technology. Firstly, the flow and implement steps are introduced, then take the solder joint as an example, to show the application of the computer simulation method in a specific way, finally, summarizes the application prospect...
