Abstract: Traditional DBC（Deadline and Budget Constrained） scheduling algorithms，such as time optimal scheduling algorithm and the cost optimal scheduling algorithm are in deadline and budget constraints，satisfies the deadline and budget unilateral QoS demand.In response to the shortage，this paper proposes a cost-effective resource scheduling algorithm based on DBC，considering the deadline and budget QoS demand，aiming at raising tasks，as well as the cost-effective of the tasks，and through reasoning arg-umentation and simulation，the paper verifies the effectiveness and superiority of the algorithm.
