Aiming at the characters of emergency, urgency, continuity, and criticality of heart first aid, generated stochastic Petri nets was introduced to model and optimize the process of heart first aid. In the process, the stochastic time was taken into account, and the time characteristic of the process was analyzed. Via process optimization, the execution time of each node was shortened and efficiency...
Model predictive control (MPC) is to solve an optimization problem for a finite future at current time and to implement the first optimal control input as the current control input. To improve the performance of the Stirred Tank Reactor, a new method based on predictive hierarchical control was introduced. As a modification of the regulatory controller usually implies higher costs, it is a common...
Proxy cache which is an important device to guarantee the quality of Web service works with a poor efficiency when hot-spot appears. To solve this problem, load balancing method should be applied. In this paper, a load balancing model based on ant colony behavior is put forward. In the model, agent monitors the status of proxy server it has been installed on. Based on that status, if it judges that...
