Research on Multi-Objective Dynamic Priority Request Scheduling of Business Web System

The general target of request scheduling is to maximize throughput and minimize response time under the condition that existing system resource is in full use. But for a busy business Web system with the goal of revenue generation, it is crucial to increase the completion rate of transaction related requests and requests from VIP. Aiming at the multi-objective of request scheduling for business web system, the multi-objective dynamic priority optimization scheduling mechanism and algorithm is proposed based on reward-driven multi-dimension criterion for request classification and one-step-ahead overload estimation. Simulation experiment shows the validity of this scheduling algorithm.
