Research Of Dynamic Pricing Strategy In Grid Market

Through the integration of the computation, storage and communication resources, the grid can provide widely resource share for the members in the virtual organization. Grid market can accelerate the development of grid technology. However, the application of economic theory in the current grid is focused on resource management and task scheduling, rather than grid market trading platform. Through grid market trading platform, the organizations that own idle resources can sell these resources and obtain the corresponding income; the organizations that need resources can use others'resources through grid platform and reduce their cost.In order to establish grid market trading platform better, dynamic pricing strategies and characteristic of grid market is researched. According to competition among resource providers, dynamic pricing strategies based on QoS feedback is proposed; according to exponential smoothing theory, dynamic pricing strategies based on the feedback of supply and demand is proposed; according mutual consultation, supply and demand, a pricing strategy in continuous double auction is proposed. In order to test and evaluate these dynamic pricing strategies, a grid market trading simulator is established. It simulates posted price market trading, one-to-many market trading and continuous double auction trading. In this simulator, these strategies is implemented and tested.Test results show that the dynamic pricing strategy based on QoS feedback can effectively adjust the price according to competition between providers. When the stability comes, it reflects the true price difference caused by fixed QoS. The dynamic pricing strategy based on the feedback of supply and demand can effectively change according to consumer demand in market. Dynamic pricing strategy in continuous double auction can make market price achieve overall balance, according market bid and potential consultation.
